How to Use a Different Webcam on a MacBook
All MacBook laptops include an integrated FaceTime webcam that you can use to record quick videos and engage in video calls or chat. For most tasks, the FaceTime webcam is more than adequate and provides reasonably good clarity and resolution. However, if you need to create professional videos with higher resolution and sharper images, or if you just want to use a different webcam, OS X does provide native support for a few Apple-authorized aftermarket cameras. Adding and using a standard USB webcam with your MacBook, though, requires a little extra work.
How to Scan for Bluetooth With the IPod Touch
In addition to being able to play your favorite music and videos, the iPod Touch also supports wireless technologies such as Wi-Fi and Bluetooth. With a Bluetooth connection, you can stream music from the iPod Touch to a compatible stereo system, go hands free with Web chat and even print files on some wireless printers. To use Bluetooth with an iPod Touch, though, you must enable the connection, and then scan for and pair a compatible device.
How to Program My GPS for Freeways
GPS technology has changed the way many travel. For GPS owners, gone are the days of frantically thumbing through maps and looking for an obscured address number on a business exterior. Simply enter an address and your dash-top devices gives you turn-by-turn directions. Sometimes, however, an address located on a freeway can be somewhat challenging; you often have to exit and loop back to the location. GPS systems have features to solve this challenge.
How to Check for Leechers on a Netgear Router
Wi-Fi leechers slow down your Internet connection and may cause you to pay overage fees if they use too much of your bandwidth. More importantly, though, leechers may be able to access sensitive files through the network or bring the authorities to your doorstep if they perform illegal activities using their computers. Consequently, you need to be able to detect Wi-Fi leechers, boot them off your Wi-Fi and prevent them from stealing your bandwidth in the future. With a Netgear router, determining if you have leechers on your network and disabling their access is relatively straightforward.

To access a D-Link router's configuration settings you need the router password. If you're unable to remember the password, you can reset the router and clear the password. D-Link routers are designed with a Reset button to easily clear the settings and give you access to the router settings once again. If you're unsure whether or not you have changed the router's password, try the default password, which is a blank space.
When you buy a wireless Linksys router, you're actually buying a switch, a router, a firewall, a wireless access point and other networking devices together in a single package. When you set up your router, you can choose to enable or disable each of the networking features Linksys provides. For example, if you have multiple routers on your network, you might disable the routing capability and use that router as a switch. Similarly, if you don't need or don't want the device to be a wireless access point, you can disable the Wi-Fi and use the device as a wired router.
GPS receivers have been common auto accessories since the late-1990s, and they have become part and parcel to smartphones since 2008 because the receiver hardware and the digital signal processing chips have dropped in price. GPS mapping software shows your current position on a map overlay, and on many units it can still display the basic coordinates for navigation with a paper map.
Global positioning systems get you to your destination accurately and directly. Behind the wheel, though, it's dangerous to manually enter commands or constantly glance at the screen to follow imprecise turn-by-turn directions. Using text-to-speech, turn-by-turn or voice-guided commands with your smartphone or portable GPS unit helps you to follow the directions safely.
Your Garmin mobile GPS device houses quite a bit of personal data. Should you make the decision to sell the unit or give it away, you will want to remove this information. Performing the master reset process deletes your Garmin ID, while reverting the unit to its factory state and keeping your personal information safe. Additionally, this process is mandatory for the new owner to register her information.
Portable devices like smartphones and GPS units have the ability to track, map and guide you through the use of geolocation. Using cell towers, satellites or some combination of the two, these handheld devices allow you to find locations and for you or your device to be found if lost. Turning this feature on with your iPhone, Android device or Garmin GPS unit is a matter of a few quick button presses.
Garmin and TomTom global positioning system devices reliably and accurately get you to your destination. Although the core functionality of the two brands' devices are similar when considering text-to-speech features and large databases, there are notable differences with other elements. Interface, routes and traffic data, athletic endeavors and smartphone support all have derivations which you may prefer on one brand and not the other. Getting to know these differences helps when transitioning from one brand to the next, or when evaluating which one to get when shopping for your first GPS device.
You probably use the Global Positioning System to find your place in the world, plotting locations on virtual maps and guiding you where you want to go. GPS is also used to find people equipped with GPS devices. Children, Alzheimer's patients and criminals can all be located with dedicated GPS trackers, or through location information emitted by a smartphone.
A GPS navigation unit is several technologies bundled into one device. It's a GPS receiver that gets a positional fix from satellites, as well as a display unit. If the display unit can display an icon for a given position over a map overlay, that combination of receiver and graphical display is known as a GPS locator map, and this is, broadly speaking, the most widely held view of what a GPS device is.
Garmin's ability to upload custom maps adds value and versatility to an already competent navigation system. Whether used for exploration of historic places or campuses or for navigating your next hiking trip, the feature allows you to cross-reference or integrate a paper map into data from Google Earth. As long as the map is compatible with your device, open for use to the public or you own the rights to it, you can use this tool to easily get from place to place.
The National Marine Electronics Association has a series of standards for connecting electronics such as fish finders, GPS and autopilot devices among others. The standards ratified in 2000 team with NMEA 0183, governing electrical-signal requirements. These mandates help manufacturers create devices that work with one another, in addition to providing standardized specifications for consumers.
Bluetooth protocols allow users of compatible hardware to send, listen to and view files via a secure wireless digital signal. MultiMedia Cards are the immediate predecessor to Secure Digital media. MMC cards generally are forward compatible with devices that take full-size SD cards, so sending an MP3 file to your Bluetooth-enabled device is a matter of pairing the sending and receiving hardware correctly.
Since its founding in 1989, Garmin GPS Ltd. has manufactured over 100 million devices for a hungry market seeking directions on roads throughout the world. Sometimes, even with the millions of points of interest and roads listed on a Garmin, there are rural roads that simply are not listed. Some communities use vague addresses such as "Route 1" as a basic address, rendering a GPS less helpful. Your device can still help you find your way, even in this challenging situation, with a little more information.
If you are serious about running and fitness, a GPS-enabled runner’s watch can be an invaluable tool for maximizing your performance. In addition to tracking your speed and mapping out your runs, these devices can provide a host of other tools to enhance your training, keep you safe and provide vital information about your workout.
Global Positioning System devices are commonly used to find your location in the world, plotting position using satellites, cell-tower triangulation or a combination of the two. When used for investigations or simply keeping tabs on your employee or child's whereabouts, employing GPS tracking can be incredibly useful. Understanding the different types of GPS tracking will help you make a determination as to which is the most effective for your needs. In terms of accuracy, there is very little difference between active and passive GPS tracking devices. The key difference lies in data retrieval.
Finding azimuth is an essential task when attempting to navigate from point to point. Azimuth is the horizontal line on a map measured clockwise connecting two coordinates, referencing a base direction. This direction is typically due north. Unless you're in the military where you will be looking for grid or magnetic azimuth, you will normally be searching for true azimuth when using two known coordinates from your GPS device. Using a conventional map and protractor, you can quickly find azimuth.
Garmin GPS devices perform their essential task of getting you from place to place reliably and as quickly as possible. On occasion, Garmin GPS users experience a nonresponsive touch screen or inaccurate response. Like many touchscreen devices, Garmin GPS units often require screen calibration. Resetting the screen so it does what you expect when you command it is an important thing to know as a prospective or current Garmin owner.
Global Positioning System units connect to external audio devices via the headphone jack, using USB ports for power and firmware updates. Like any portable electronic device, headphone jacks eventually become havens for trapped dirt, pocket lint and other contaminants. In order to prevent intermittent or otherwise impaired sound, occasional cleaning is required. Although an essential task, it is relatively straightforward and not normally something requiring sending the unit for service.
Global positioning system devices use satellites to plot your location within a few feet. In order to give turn-by-turn directions and provide more accurate coordinates relative to places of interest and other landmarks, GPS devices must track your speed as you walk or drive along your route. By accessing the right feature on your GPS device, you can determine with a high degree of accuracy.
Garmin Ltd. was founded in 1989 by Gary Burrell and Dr. Min Kao and has since produced over 100 million products. The Garmin nuvi GPS line offers a diverse array of products for a variety of applications ranging from the casual driver to a professional. This product line includes models priced below $100 to more fully featured models priced a few hundred dollars higher. There are several key characteristics that distinguish the groups of nuvi models.
GPS technology has come a long way since the military navigation systems of the 1960s and '70s -- from fighter jets and battle ships to station wagons and minivans. More civilians now use GPS than miltary personnel. TomTom makes several models of GPS, including the TomTom Start 45M, TomTom Start 55TM, and the TomTom VIA 1535TM. While they all offer similar navigational capabilities, each model has distinct characteristics to consider when choosing your next GPS navigator.
A GPS receiver can make your life a lot easier if you spend much time on the road. However, that technology can come at a price, with manufacturers churning out pricey new models with new features every year. If you want to enjoy the benefit of GPS navigation without succumbing to sticker shock, prepare to do some comparison shopping. Making a few wise choices when it comes to features, or adapting a device you already pay for, may save you a lot of money in the end.
Losing track of a child, even for a few minutes, can be a harrowing experience for any parent, particularly if your child has special needs. Devices that use GPS and other technologies can serve as excellent tools for monitoring a special needs child, whether a toddler or a teenager. Selecting the right tracking device can give you and your child peace of mind.
When you upgrade the Windows operating system on your computer or run into a virus that alters files, your Internet Explorer Favorites folder could be affected. The Favorites folder is where Internet Explorer stores and organizes bookmarked Web pages. Operating system upgrades or viruses can hide, delete or move the Favorites folder. The key to restoring the folder involves knowing where it resides, and this usually depends on the specific version of Windows running on your computer. In some cases, you may have to redirect Internet Explorer to the correct folder location in the registry.
The Galaxy series of tablet computers from Samsung contain circuitry that allows them to function as GPS devices when appropriate mapping apps are installed. They can use any available Wi-Fi networks to establish their current position. Although there isn't a direct connection between GPS and Wi-Fi, some apps seamlessly switch from GPS navigation to Wi-Fi navigation when you step into compatible indoor locations.
The in-dash GPS devices in many cars provide an impressive level of integration, combining your car stereo, cellular hands-free capability and other features with the GPS screen. Portable GPS devices can't perform all the same functions, but Bluetooth-enabled models from Garmin and other major manufacturers can pair with compatible cellular phones to provide enhanced features.
GPS receivers have become familiar sights in modern cars, but these devices have many uses beyond the automotive. Hikers, anglers, golfers and other outdoor enthusiasts can all benefit from the navigational powers of the global positioning system. There are many different types of GPS receivers on the market, each geared toward its specific market and offering distinct advantages to the user.
For the navigationally challenged, there's never been a better time for travelling. Anyone with an Internet connection can use Google Maps or similar services to locate specific businesses or destinations, and a portable GPS device can actively help you navigate to anywhere you need to go. It's especially helpful when you can locate the information you need on Google and then transfer it to your GPS device. Garmin collaborated with Google to streamline this process for users of its Nuvi devices and other compatible GPS navigation products.
If you enjoy hiking and the great outdoors, one of the most valuable tools you can own is a hand-held GPS receiver. GPS technology provides an amazingly precise level of navigation assistance almost anywhere on the planet and may serve as an important lifeline in a time of crisis. A good hiking GPS tracker will include a number of valuable tools any outdoor enthusiast can rely on.
Automotive GPS units can save you considerable time and frustration on road trips or on your morning commute. However, with so many different models on the market, choosing the right one for your needs can be a confusing experience. Understanding the different features offered by each model can help you make the right choice for your needs and provide you with a navigational aid that will serve you for years to come.
Garmin began in 1989 when founders Gary Burrell and Dr. Min Kao and some fellow engineers began to evaluate how GPS satellites could be used commercially and for a casual user. Garmin GPS has since evolved into a line of products that not only help you navigate in your car, but have hiking, camping, jogging, sailing and aircraft applications as well. Since its founding, Garmin has sold more than 100 million units. Once priced in the thousands, these units start at under $100 today. Finding a Garmin GPS with the features and price you want requires a close evaluation of your GPS usage and the model's corresponding features.
Certain mapping services, such as Google Maps and Mapquest, incorporate a "Send to GPS" feature that allows you to download destination addresses or phone numbers from an Internet map search to select global positioning system (GPS) navigation units using a USB or wireless connection from the computer. This saves you from having to re-enter a destination address you have already searched for on the computer. While most Garvin and Pioneer GPS units provide support for "Send to GPS," some brands, such as Magellan and TomTom navigation units, do not. Users of these systems are still required to key addresses into their GPS units.
Global Positioning System devices are passive satellite receivers that tell you where the device is located at any moment on the earth. They have two main uses: tracking you where you are and telling you how to get where you want to go. GPS devices represent extremely sophisticated technology that was originally used by the U.S. military. Consumer models were restricted in their accuracy until the year 2000. However, today anyone can access GPS technology with a range of devices you can put on your car dashboard, tuck in your pocket or wear on your wrist.
Fishfinders are electronic devices that use sonar to detect where fish are swimming, eliminating much of the guesswork and frustration involved with fishing. Effective in either freshwater or saltwater, fishfinders come with a number of different features designed to make fishing as effortless as possible, including built-in GPS that reveals your exact location on the water so you can chart your most productive spots. Selecting a good GPS fishfinder requires considering a number of important factors.
Handheld GPS units enhance a variety of outdoor activities. Hikers and anglers find GPS devices invaluable tools for their activities; golfers use GPS units to track information about courses, and no geocacher could participate in his chosen activity without a handheld GPS unit to guide him. With so many different activities that benefit from handheld GPS devices, selecting the right unit for your needs can be a tricky proposition.
Like many other high-tech devices, portable GPS navigators are wonderful when they work properly but maddening when they don't. For example, you might find that your GPS only gives you a blank screen when you try to turn it on and use it. The causes are similar from brand to brand; usually a software conflict similar the kind that results in a computer crash is the culprit. The recovery process varies. For example, if you have one of the devices in TomTom's XL series, you need to reset the device and possibly reload its software using TomTom HOME.
The rise of GPS technology has made it difficult for even the most directionally challenged drivers to get lost, but personal navigation is only one use of the technology. Another significant use is tracking devices to monitor the health and well-being of people -- for example, children, seniors or handicapped people. GPS locators for children are especially varied, because the needs of toddlers, preteens and teens are quite different.
The Personal Hotspot feature, called "Internet Tethering" in early iOS devices, enables you to use your iPhone as a mobile hot spot for an iPad. Personal Hotspot tethers the two devices via Bluetooth, allowing you to maintain a constant Internet connection while saving battery power on both the iPhone and the iPad. To use this feature, you'll need to pay your wireless service provider for tethering access. You'll also need an iPhone 3G or newer device that runs iOS 4 or a later version.
The Sony PlayStation Portable, or PSP, combines a wealth of control options with a powerful processor and high-quality graphics. Aside from its primary purpose as a gaming system, the PSP is a versatile mobile platform for other uses such as GPS navigation. You can use the optional GPS accessory for conventional navigation, and many games utilize GPS to enhance the gaming experience.
Portable GPS devices use their internal memory or SD cards to store data, including their standard set of maps and millions of points of interest. The in-dash units installed in cars work in much the same way, but some older systems use a specialized DVD disc for their maps. The real-time navigation is still done by satellite, so this older technology works like any other in-dash system as long as you keep your maps updated.
Bluetooth is a short-range wireless connection protocol, commonly used for connecting mice and headsets to computers and phones, respectively. It can also be used to connect your Droid phone to your computer without cables, so you can conveniently move photos to and from the device. While not all carriers support it, the Droid phone is capable of tethering, which lets your computer connect to the Internet over the phone's connection.
If you pair your Motorola Bluetooth headset with multiple mobile devices, you may get unexpected errors when you try to pair it with a new device. To solve the issue, you can reset the Motorola Bluetooth device. Resetting the device clears it of any pairing. After you reset the headset to its factory defaults, you need to re-pair the device before you can use it with the mobile device.
Many consumer electronics devices have their roots in military technology, including the frequency-switching of cell phones and cordless phones -- originally developed for guided weapons -- and autofocusing cameras, based on gunsight technology. Another common example is GPS navigation devices, which use a system of satellites originally established for the use of the U.S. armed forces. By triangulating signals from three to five satellites, your GPS can tell you where on the planet you are. Some models also receive traffic data from other sources, to help you avoid road closures and gridlock.
Garmin's Nuvi line of GPS navigation devices is broad and diverse, with a range of current models and a number of features common to many of them but not all. This can cause a bit of buyer's paralysis in shoppers who are trying to find the mix of features and price that works best for a given use. Savvy shoppers study the available features and identify the ones that matter to them before hitting the stores.
Bluetooth is a wireless standard for personal-area networks. It uses low-frequency radio broadcasts to transmit data between electronic devices, in a set of frequencies that won't penetrate most construction and that don't reliably extend past about 6 feet. First introduced with prototypes in 2000, Bluetooth has gone through multiple generations of the basic protocol and gained ancillary functions which might well be protocols of their own.
Global Positioning System (GPS) satellite fixes give precise coordinates on the surface of the earth with a three-satellite lock. With signals from four satellites, the GPS receiver can pinpoint a position in 3-D space, giving latitude, longitude and altitude. This information gets used for GPS guidance of airplanes, guided munitions for the military, hiking data and surveying.
If you have a Microsoft-built Bluetooth peripheral and want to connect it to your computer or you own a peripheral -- such as a Microsoft Windows Mobile smartphone -- that's built to work with a computer running Windows 7, you need to install the appropriate drivers to use the device. You can download the drivers directly from the Microsoft Hardware website and then install them on your computer or use the disk that came with your device to install the correct drivers. You can also find the latest drivers on the manufacturer's website.
GPS personal navigation devices have plummeted in price and grown a wide range of features. With the rise of GPS applications on smartphones, these trends are only going to continue. As GPS devices have matured as a category, many features that were formerly the province of one manufacturer are now widespread. It's difficult to go wrong with any GPS unit in the current market.
Unlike Wi-Fi or cellular connections, which enable communication over longer distances, Bluetooth connects devices that are around 30 feet or less apart. Most commonly used to connect a headset to a mobile phone, Bluetooth uses low power but enough data speed to send high-fidelity music from your smartphone to wireless speakers, and is versatile enough to connect a wireless keyboard and mouse to your computer. To connect two devices using Bluetooth, you must "pair" them, so that they recognize each other. While the steps are similar for many devices, the instructions for your specific devices will vary by manufacturer and model.
In Windows 7, Bluetooth File Transfer walks users through the data exchange process with Bluetooth-enabled devices. Depending on your computer setup, the wizard may launch automatically when you attempt to add a Bluetooth device or it may need to be launched from the command line. The Windows operating system supports Bluetooth version 1.1 and higher, with Windows 7 supporting version 2.1 and Windows 8 supporting version 4.0.
Both the Apple iPhone and iMac come with Bluetooth technology built inside, meaning they can both connect to many of the same Bluetooth devices like headsets and keyboards, and also with each other. Bluetooth uses radio frequencies to connect devices within what is called a Personal Area Network (PAN) up to a distance of 164 feet, depending on the devices being used. For best results, you should generally use them within 30 feet of each other. Note that Bluetooth media streaming is not possible between an iMac and an iPhone; if you wish to stream media, you can use Wi-Fi.
One of the little-heralded changes in how technology shapes our lives involves the rise of Global Positioning System receivers. Initially created as a military guidance system for submarines and ships at sea in the 1970s, and upgraded over time, this system became available for civilian use in 1994. Its impact has ranged far from the original military scope – we're moving towards an era of self-driving cars in which people never need to look at a paper map.
The Global Positioning System or GPS uses satellites positioned over the earth to triangulate the position of your GPS device on the surface. There are many options for GPS services that help you determine your own location and give you directions to other places. You can use any device, including GPS locators, cell phones and tablets, to find your GPS position. You only need an open view of the sky. You can also get the latitude and longitude coordinates of any location on earth using your computer.
Like any form of personal electronics, GPS devices are a delight when they work properly, but maddening when they don't. One common issue you may experience is slow detection of the global positioning satellites, especially if you haven't used the unit for a while. If watching your GPS laboriously track down the satellites is hard on your nerves, there are some things you can do to speed the process.
USB and Bluetooth are peripheral connection technologies. They connect devices like printers, keyboards and headsets to computers, smartphones and other devices. Bluetooth is a wireless protocol. USB is primarily a wired connection protocol that can also be used to power devices. A large number of cell-phone cables use microUSB as a charging standard. There is a Wireless USB specification, but it never got wide adoption.
GPS navigation devices can be a boon for any motorist, providing crucial information about routes and points of interest along the way. Professional truck drivers have even more reasons to value a GPS, and several trucker-oriented models are available from major and minor manufacturers. In addition to the standard features available in consumer models, these GPS devices have a number of specific features just for truckers.
Lane Assist is one of the most useful features available on modern GPS units from Garmin. When available, it simplifies the process of navigating your way through unfamiliar settings and complex traffic interchanges. It's not a feature that can be enabled or disabled. If your GPS has that feature, it's always ready to use. If your GPS lacks Lane Assist, you'll have to upgrade to a newer or more feature-rich model.
While most people use the iPhone's well-known, on-screen keyboard to send messages or type notes, sometimes you may need to enter more text than your thumbs can handle. Fortunately, Apple has built in Human Interface Device Profile support for the iPhone, enabling Bluetooth wireless keyboards to pair with and input text to the device. Whether you want to use your iPhone in a bring-your-own-device workplace or you want to write your next novel on the go, using a full-size Bluetooth keyboard may improve both your ergonomics and your speed.
Samsung Bluetooth headsets wirelessly connect with a variety of Bluetooth-enabled devices, such as smartphones, MP3 players and computers. "Pairing" the headset establishes a connection with the Bluetooth device. To prevent the headset from inadvertently connecting to other devices, Samsung secures the connection by requiring manual entry of a security passkey, which verifies the appropriate device. Samsung typically uses "0000" as the passkey, but this number should be confirmed by reviewing the headset's manual.
Apple wireless keyboards are included with new iMac computers, but they are also available for any Mac running at least OS X 10.6.8. For the keyboard to work with your Mac, it must be paired using Bluetooth wireless technology. Keyboards included with new iMac computers are prepaired with the iMac, so pairing is as simple as turning on the keyboard. However, to use that same keyboard with another Mac computer, you must sever any current connection and manually pair the device to the other Mac.
Each iPhone contains a Bluetooth radio that can link to nearby accessories without using cables. Bluetooth allows wireless devices such as keyboards and headphones to be easily connected. In order for a Bluetooth device to work properly, it must be "paired" to the iPhone. The pairing process is typically simple to perform, and can be completed in under a minute.
MapSource is a trip-planning program developed by Garmin. This software allows users to create and edit waypoints and routes on a map. These navigational plans can then be loaded onto a compatible Garmin GPS device. In 2011, Garmin replaced the MapSource product with updated software called BaseCamp. However, the legacy MapSource program can still be downloaded and installed by users who prefer this software.
Most automotive GPS units are used for driving to a specific address or point of interest. Sometimes, however, it is useful to navigate to a cross street. An intersection can be a convenient landmark, and is sometimes easier to use than a full street address. For security reasons, you might wish to enter a nearby intersection as your home instead of your actual street address, in case your unit is stolen. Most modern GPS units allow users to enter to streets and navigate to an intersection.
There are many different varieties of GPS devices and apps. Some devices are specialized for a specific purpose, while others are designed for general use. Regardless of the exact design, all GPS units use satellite signals to provide useful navigation information. GPS features can be used from a smartphone, or on a stand-alone unit. There is no single best GPS device that matches the needs of everyone. Buyers should consider how they intend to use the unit, and select a GPS device that most closely meets their needs.
Street addresses are a convenient way to identify a location to other people. Devices such as GPS units, however, use a set of numbered coordinates to determine a point. This latitude and longitude number can be useful for many purposes, such as saving the exact location of a geocache or finding a point on a topographical map. Several online apps can quickly convert a normal street address into GPS coordinates.
Like most electronics manufacturers, Garmin offers a range of useful services to registered owners of its GPS devices. Registering the product means you'll be able to get warranty service even if you've lost your purchase receipt, and if your unit is stolen Garmin will be able to locate it when it is used again. Registered users also receive regular firmware updates, keeping the unit current. Registration is a simple process that takes only a few minutes.
Garmin's GPS devices can be updated and customized regularly with additional maps, providing higher levels of detail for geocaching and vacation planning or simply adding new geographic areas. Over time, these additional maps can take up a significant percentage of your device's available storage space. Freeing up that space by deleting your supplemental maps can restore your ability to add new data, and it's both quick and easy to do.
Modern smartphones and many feature phones support Bluetooth wireless technology. Restrictions regarding cell phone use on the road in many states make choosing the right Bluetooth headset an important consideration if your car doubles as an office extension. A Bluetooth headset should provide a combination of call clarity, comfort and solid battery life, so that you can rely on it for important calls.
Speed is the distance covered over a given interval of time. GPS systems give position fixes that are updated multiple times per second. This information is used by a computer algorithm to provide a ground speed. This ground speed often differs from the miles per hour shown on a car's speedometer. Figuring out which of those speed displays is more accurate is a bit tricky.
GPS coordinates are presented in a format that dates back to the Age of Aail, giving the number of degrees east or west of the prime meridian in Greenwich, England and degrees north or south of the equator. Your GPS receiver also presents coordinates in this system, though it does the spherical trigonometry for you and is much more accurate than anything a Napoleonic captain could've dreamt of.
Using a GPS in your car is usually a simple matter of attaching it to the windshield, where it's easily visible but doesn't obstruct your view. However, this might not be practical in other vehicles. For example, impeding the view from an aircraft window can have fatal consequences, so airborne GPS units are often mounted on the craft's control yoke. You can use similar mounting systems for motorcycles and mountain bikes, providing easy visibility and convenient access to the screen.
Geographic Information Systems and the Global Positioning System are complementary technologies. GIS systems are high-resolution maps, with a lot of additional information available that can be referenced by map coordinates, and GPS receivers can generate precise latitude and longitude coordinates over most of the earth. These technologies are the two halves that form the whole of turn-by-turn navigation devices, such as a Garmin Nuvi or TomTom.
In the civilian market, Global Positioning System navigation is used most often for turn-by-turn navigation devices, which, as they've matured, have plummeted in price and increased in features. Now, the technology even works as a smartphone application. Other uses of GPS include marine and aviation navigation systems, Internet network timekeeping, and monitoring the time and position of delivery trucks, pet collars and even children.
Powerful, portable GPS devices make it possible for even the most directionally challenged drivers to plan a worry-free vacation. Many models from major manufacturers such as TomTom have the ability to plan a complete itinerary for your vacation or road trip. These include both destinations you're aiming for and waypoints you'll pass through without stopping.
Garmin GPS units allow you to save and upload key points of interest, known as "waypoints." These locations can be favorite restaurants, important highway exits, shopping centers and hotels. They are uploaded to the GPS unit via BaseCamp, Garmin's GPS device management software. Using the Garmin USB data cable, you can save those locations you'd love to visit again directly to your Garmin GPS unit, in addition to your computer.
Handheld GPS units are dedicated single-function devices used for hiking and land navigation, including a hobby called geocaching. Smartphones are general purpose computing devices that have a lot of different functions. Smartphones, like cell phones before them, are part of a trend that converges several formerly separate devices into one gadget. The camera phone has largely replaced the small point-and-shoot camera, and the smartphone is in the process of taking over the product niche of the dedicated handheld GPS device.
Garmin BaseCamp is mapping interface software that allows you to view maps, plan routes and mark tracks and waypoints on your computer and then transfer them to your handheld Garmin personal navigator or the BaseCamp app on your GPS-enabled smartphone. With the track drawing feature in BaseCamp, you can plot your planned route and also view topographical data such as elevation changes that will help you to assess the difficulty of a bike ride or hike. When you transfer the new track to the device or smartphone app, the track appears on the map as a dotted trail and the GPS device displays your progress as you move along the track.
Bluetooth compatibility provides a convenient way for your electronic devices to communicate with each other. Originally intended for wireless cellular headsets, it's now used for everything from home audio to portable GPS devices. If your GPS and cell phone both support Bluetooth, you can link the two to use a variety of helpful travel and safety features and services.
The Global Positioning System (GPS) satellite network has revolutionized ocean travel and maritime trade. It's also made recreational boating, both on lakes and on the open sea, much safer for boaters. It doesn't completely replace the skills needed to properly navigate on a course on the open water, but it significantly lowers the barrier to entry. If your primary exposure to GPS navigation is a turn-by-turn city navigation app, there are some differences to keep in mind.
GPS devices are frequently in contact with fingertips and fingernails, thrown into pockets and backpacks and generally subjected to many things that scratch the screen. Finer scratches on GPS screens are quickly removed using mild abrasives, restoring your GPS unit's screen to a like-new appearance. In addition to cosmetic improvements, removing scratches can also improve visibility of small map details that may otherwise be obscured, especially in direct sunlight.
Global Positioning Satellite (GPS) navigation has become a household term. The first GPS satellites were launched in 1973, and public access was available in 1994. GPS is maintained by the United States Air Force, but competing systems include the Russian GLONAS system, which works on the same principles.

We spend more time in our vehicles during daily commutes than we like to acknowledge. In many cases, this time is wasted sitting on a backed up highway or in a parking lot waiting for an appointment. When we aren't tasked with paying attention to other drivers and hazards, we can use these moments to stay productive or connect to social media. From in-vehicle systems to tablets and smartphones, there are fewer reasons than ever to waste time in the car.
Pairing two Bluetooth-enabled devices creates a wireless connection between both devices for transferring data. Common uses of Bluetooth include headset communication, wireless navigation with a mouse or data transfer between smart phones. Some devices require manually entering a passkey to prevent unauthorized pairing with Bluetooth devices. Most manufacturers use a simple, default passkey, but others use one linked with the product serial number or a randomly chosen value.
The Sony Vaio's internal Bluetooth adapter simultaneously and securely connects with up to seven devices within a range of approximately 33 feet. However, Bluetooth's 2.4GHz frequency range potentially interferes with some communications, so Sony integrates a hardware and software switch for disabling the adapter to prevent interference, for example, during a plane's takeoff. Wireless technologies also require additional battery power, so disabling wireless communications minimizes battery draw when Bluetooth is not required. Before using Bluetooth, you need to turn it on via the hardware switch and internal software controls.
The Jawbone line of headsets use Bluetooth technology to create a wireless connection to your phone, allowing you to use the phone without having to be tied to it by a cable. To start using your Jawbone, you first have to go through a pairing process to connect it to your phone.

Bluetooth is one of the older wireless technologies and has been around since 1999, but it really did not become popular until mobile devices such as the iPhone, Android smartphones and mini-sized MP3 players became mainstream products during the mid-2000s. Many smartphones and MP3 players support audio streaming over a wireless Bluetooth connection. Therefore, if you have such a portable device, you can connect it to your car or home stereo and listen to music on the player without headphones. Even if the stereo does not have native Bluetooth support, you can connect mobile players by connecting a Bluetooth adapter to the “AUX” or “Auxiliary” input.
In 1997, SanDisk and Siemens jointly released the MultiMedia Card. Almost immediately, MMC became the standard for storage on MP3 players, smartphones and other mobile devices. In 2001, manufacturers began releasing Secure Digital SD cards based on the original MMC design. MMC and SD cards are identical in size and even interchangeable in many devices labeled “SD/MMC” compatible. As a result, you can copy music files from a mobile device with a standard SD slot directly to MMC media on many devices. However, if you need to transfer MP3 files from a portable device with a MiniSD slot or no memory to one that uses MMC media, you can do so by using a your computer, a USB card reader and a Bluetooth connection.
Bluetooth is a type of technology that is used to connect devices and accessories using radio signals. The Bluetooth protocol permits data sharing without wires. Introduced in 1994 by the Ericsson electronics company, Bluetooth is now relatively common in cell phones, headsets and other portable devices. While it is very commonly used for connecting to cell phones, Bluetooth can be used to link a wide range of devices, ranging from laptop computers to keyboards and even printers.
Generally considered the brainchild of science fiction writer Arthur C. Clarke, the Global Positioning System consists of 24 communication satellites in geosynchronous orbit about 23,000 miles above the Earth. First intended for military use, GPS came into commercial use in the late 1990s and soon became an essential tool of the transportation industry. Whether moving by land, sea or air, GPS plays a vital role by streaming real time data as to the location of people or commodities. According to a 2011 report on U.S. GPS usage by Nam D. Pham, Ph.D., “GPS technology will create $122.4 billion benefits per year and will directly affect more than 5.8 million jobs.”
If you have not used a Bluetooth device with your iPad for a long time, if you deleted it from your Bluetooth device menu, or if you have recently reinstalled the iOS operating system, you may find that the iPad has forgotten how to connect to it. Reconnecting a Bluetooth device is just like connecting it for the first time. This is done by putting the device into discovery mode and then pairing it with the iPad. If you've not used the device in a long time, consult the user guide to refresh your memory on how it should be connected and if a passkey is required.
