If you've ever worried about Big Brother watching you, there's one more reason to be suspicious.

I was recently reading an article about TomTom, a GPS manufacturer, selling information gathered from their units regarding customers' driving habits. The buyer? Local governments.

TomTom thought the information was going to be used for building roads and implementing safety features, but it was also used by the police to target areas where motorists were driving over the speed limit. Armed with this information, the police set up an officer with a radar gun to issue speeding tickets.

It is a bit creepy that the government has information on where people are driving and at what speed.

TomTom uses the information gathered from drivers to help determine optimal routes, especially during rush hour when traffic slows to a crawl.

I don't have a problem with my GPS tracking vehicle speeds if it is used to help me find where I'm going, and if a police officer happens to catch me speeding with a speed detection device I'll understand, but the police having information on my driving habits makes me uncomfortable. TomTom has issued an apology and promised to not sell any more information. Hopefully no other GPS companies have acted in a similar fashion.

Memorial Day is almost upon us once again, and all the holiday traffic will be making the roads more hazardous than normal. Law Enforcement Agencies across the country will be increasing the number of on-duty police officers for the holiday weekend, but even with all the additional cops on the roads many neighborhoods will have to deal with dangerous traffic violators.

If you would like to lend a hand to the police, use your own police radar gun to track the speeds of motorists in your neighborhood. The Bushnell Speedster III is an easy to use and affordable radar gun. Designed specially for RadarGuns.com, the Speedster III employs simple point-and-shoot operation, while providing accurate speeds up to 200 mph.

With your radar gun, a pad of paper and a phone, you can give the police accurate descriptions of speeders in the area. While the data you give the police will not result in a speeding ticket, it may help cut down on dangerous driving.

Make sure to take note of the vehicle's make, model, color and license plate, as well as a description of the driver to give the police with the reading you get from your radar gun. When you report the speeder, ask that a Community Relations Officer get in touch with the driver.

Slowing down dangerous drivers in your neighborhood is especially important if there are children nearby. Memorial Day weekend should be a fun time filled with positive memories of spending time with your family while having a cookout or going camping. Help ensure those good memories by equipping yourself with a speed detection device and helping the police slow traffic violators.

Radar guns have a number of uses, from clocking pitching speeds, checking golfer's swing speeds, catching speeding motorists, to monitoring the speed of an arrow as it leaves a bow. But there may be a new use for devices like radar guns: diagnosing brain injuries.

Researchers at Georgia Tech have developed a new device that uses microwave signals to read minute changes to a person's gait and coordination that may indicate a brain injury. This technology would be primarily used for determining if a person has suffered a concussion. In many instances, concussions go undiagnosed and get progressively worse as pressure builds in the brain. If a concussion is not diagnosed, it can lead to severe and permanent brain damage or even death. In recent years, soldiers and athletes have come forward to show how debilitating even minor brain damage can be.

While the technology is still in its infancy, researchers are working on scaling the cumbersome equipment down and improving accuracy so that it may become ubiquitous in first aid kits on baseball diamonds, football fields and the battle field. Someday a microwave signal gun may be sitting next to the radar gun in many coaches' equipment lockers. Check back with RadarGunsBlog.com for any new developments in radar guns.

While the use of radar guns in the U.S. has been common for years, the Philippines recently decided to increase their efforts in tracking traffic violators and issuing citations.

Chit Estella, a prominent journalist in Manila, Philippines was killed last Friday in a vehicular accident. Public outcry has prompted the Metropolitan Manila Development Authority (MMDA) to increase their efforts to keep roadways safe.

The accident occurred when a passenger bus collided with the taxi cab Estella was riding on Commonwealth Avenue. Criminal charges for reckless imprudence resulting in a homicide and abandonment of victim have been filed against the bus driver. A third vehicle was also involved in the crash but the driver has yet to be identified.

Commonwealth Avenue has been labeled "killer highway" due to the accident and a high number of similar occurrences.

The first improvement implemented by the MMDA is to equip each motocylce unit in their traffic department with a speed radar gun so that they may enforce the new 60-kilometer-per-hour speed limit on thoroughfares.

Scientists from Japan, France, and the United States have discovered that the Doppler Effect occurs at a molecular level, allowing for measurements of the rotational speed of molecules. This measurement allows scientists to better study the molecular spectroscopy of individual molecules, which enables them to determine the chemical makeup of a molecule based on the radiation it emits.

The Doppler Effect was first proposed in 1842 by Christian Doppler as a change in the frequency of a radio wave from the time it is emitted to when the same radio wave is reflected off an object back to the source. It is this principle that allows for radar guns to measure speeds of objects in motion. Police officers and baseball scouts use the Doppler Effect everyday with speed guns to help them perform their jobs.

OpticsPlanet has a full line of speed detection devices that use the Doppler Effect to measure the velocity of distant objects from trusted brands such as Bushnell, Decatur and Sports Radar. For all things radar, check back with RadarGunsBlog frequently for the latest news and sales information.
