Pocket Radar Deliver Powerful Performance That Fit Into A Shirt Pocket
Personal Rabar use processing system and a Doppler radar signal sensing coupled with re-engineered microwave and antenna components to deliver powerful performance in a device compact enough to easily fit into a shirt pocket.
In creating the world’s most compact speed radar device, we had to completely re-assess, re-engineer and re-build nearly every aspect of traditional radar technology. Using proprietary Digital Signal Processing algorithms and state-of-the-art intelligent target acquisition techniques we are able to provide users with industry leading accuracy and speed measurement in a device that is a tiny fraction of the size of traditional speed radar guns.
Personal Radar works by emitting a small pulse of radio waves like a flashlight beam in an invisible focused beam. When the radio wave hits an object that is moving toward or away from the Pocket Radar, a small amount of the wave reflects back.
The moving object modifies the reflected radio wave based upon how fast it is moving directly towards or away from the Pocket Radar. The Pocket Radar compares the reflected radio wave with the original.
The Pocket Radar then calculates the difference between the two waves, and displays the object's speed, all of which happens almost instantly. The focused beam comes from the radar lens on the back of the unit directly behind the display. Hold the Pocket Radar up vertically like a camera phone with the beam from the radar lens directly in line with the moving object you want to measure. While the target object is in motion, "Press and Release" the big red button, like you are taking a picture. The speed of the object will appear on the display.
One of customer review is Glenn Mau. Here is what he said about Pocket Radar "We use it on my son's baseball team. This pocket radar is Awesome!. It makes sure the boys are running at full speed to first base. The pocket radar will tracks the kids while they run to first base and we will be know if they are slowing down or not. The soccer team likes it was well. Great Product! Everyone wants to know who fastest kick! Can't wait to time other things like Race cars and Golf Balls coming off the club! Real easy to use! Anyone can use it! I'm going to buy a couple of more for my friends."
Does an antenna speed up you 3g modem?
I have a Novatel MC727 through a local isp and was wandering if an external antenna would speed up my internet? It is taking a pretty long to download some bigger files. My isp says i should be getting 1.2mbs but i dont ever see it when i download songs and things of that sort. So if you could help me it would be great
No, not if you are receiving a HSPDA signal (3G). If the signal is weak it could drop back to 2G or roaming which would be very slow.
It is unlikely you will get 1.2Mbps download speed, this figure is probably the bandwidth and the download sppeed will be quite a bit less. Have you done a speed test?
Also it depends where you are downloading from, some of the file servers are slow at source.
Antenna is better on iPhone 4S, Consumer Reports says (LA Times)
After blasting Apple's iPhone 4 for its antenna problems last year, Consumer
Reports magazine is giving the new iPhone 4S a little less static. The new
model "doesn’t suffer the reception problem we found in its predecessor in
special tests...
