New Year's Day is the worst holiday for car thefts

Officials from the Des Plaines-based National Insurance Crime Bureau said Tuesday that New Year's Day has been automobile thieves' favourite vacation.

Police plus insurance officials are warning drivers to be sure that while they're having fun ringing in the New Year, they're not making it simple for a automobile thief to start 2011 on a productive note.

According to National Crime Information middle figures, 2,760 cars were reported stolen on New Year's Day in 2009 plus 2,189 were taken on New Year's Eve.

Christmas day is not for giving, it's also for not stealing. According to the National Insurance Crime Bureau, December 25th is the day lots of thieves take a break from stealing cars. kind of them, no? But here's the bad news: those thieves are postponing their nefarious ways for a week. That's right, New Year's Day is the worst vacation for automobile thefts.

Here's some raw data: 2,760 vehicles were reported stolen in the United States on January 1st, 2009, plus 2,189 were stolen on New Year's Eve. Naturally, this year is expected to much do likewise, though the actual number of stolen vehicles is expected to fall for the seventh straight year.

what are you able to do to combat the issue? Mostly exercise some common sense. The NCIB recommends the following: parking in well-lit areas, keeping packages in the trunk or out of sight, plus ensuring your vehicle is locked while it's parked. And installing some alarm or with reverse sensors which has warn function, Or you could drive an unstealable automobile... Check out the entire press release after the break.

Reversing Radar Sensor

Concerning parking sensor kit, then it is related to the ultrasonic probe. The ranging advantage lies in its convenience for quick, simple calculation, easy to do real-time control. Parkin sensor is a non-contact detection and measurement precision, can be achieved in the practical requirements of industry. Take it as an example: In order to mobile robots to automatically avoid obstacles walking distance, measurement system must be equipped to make timely access to information on the distance from the obstacle. Also can be used for reversing radar, topographic mapping, construction of houses, bridges, roads, excavation of mines, oil wells.


Reversing radar sensor: In order to study and learn how to use ultrasound, it has been designed and produced a number of ultrasonic generator. Ultrasound probe, the use of sensor, generally speaking, the ultrasonic probe can be made into two categories: one is to use electrical methods generated ultrasound, another is mechanically generated ultrasound. Now the piezoelectric ultrasonic generator is more commonly used. It consists the two piezoelectric chip and a resonance plate.

When it's poles plus pulse signal, whose frequency is equal to the piezoelectric wafer. The natural oscillation frequency, the piezoelectric resonance will occur, and drive plate vibration resonance, ultrasound arises. On the contrary, if there is no applied voltage between two electrodes, it will be pressure for piezoelectric vibration when the board receives the ultrasonic resonance. The mechanical energy is converted to electrical signals, then it becomes an ultrasonic probe.
Reversing Radar Ranging: Parking sensor ultrasonic probe will emitting signal in a given time. Experiencing the measured object and then reflected back by reversing radar received. As long as the calculated ultrasonic signal received from the launch to the echo time, we can calculate the distance from the measured object, and get the propagation speed in the medium : Backup sensor probe can bring shell and line .Also can age the sensors by the high and low temperature, then the performance will be stability. Diameter size from 10mm to 22mm variety, generally based on various types of specifications to design the probe.

DIY- Install a Parking Sensor

This weekend My frined tackled his terrible parking by isntalling a universal parking sensor kit, purchased for all of US$26 from a online shop. Nothing fancy, no screens, just a simple beeper and sensors affair. This is how I fitted it, along with lots of help from Nev of course.cheers fella! He told me this story as following.

The kit is simply, only 4 sensors, a beeper, control box and it even came with its own holesaw for the sensors. I suggest you test the kit prior to attempting to fit it, imagine your mood if it was faulty!

Step 1. Bumper removal

There are 2 x 18mm bolts that hold the bumper on, along with 6 other screws around the rear wheel arches. The bolts can be found under small foam covers underneath the bootfloor roughly where the back of the rear light clusters are. The 6 screws around the rear wheel arches can be a pig to get to without removing the wheels..but a pair of mole grips locked with a suitable stubby bit at 90 degrees did the job very nicely. Or even better if you have a flexible drive, use that!. You don't need to remove the mudflaps, just the screws in the bumper.
Step 2. Dismantle and drill the bumper

There is a large aluminium section that needs to be removed, as you dont really want to be drilling this. It is simply clipped top and bottom to the plastic bumper section. This was a very fiddly job, and really needed 2 people and some decent flat bladed screwdrivers to help. Once off, there is a foam chunk underneath, that is the bit you will need to drill. Be aware of where the aluminium section that has to go back, I personally drilled upwards, so that all wiring would come out above where it would be. For the 2 middle sensors, I also drilled through the upper plastic that clipped to the aluminium section, this way all 4 sensors could be wired along the top edge.

Next, mark your sensor positions ready for drilling. I marked 1.5 inches down from the trim strip all the way along the length. With the middle 2 sensors, take into account you may wish to put a tow bar on in the future, leave enough room for this. Once your happy with the positions (check at least twice) be brave and get drilling!

Step 3. Sensor fitting and cabling

Before you attempt to fit anything, check the cable lengths of the sensors, ensure they are all equal, if some are shorter, then place those nearest where your control box will be in the boot. To pull the cables through the holes, I used a screwdriver, and taped each sensor plug to it and pulled it through. That polystyrene can be suprisingly tight to feed things through! Make sure that the hole edges are nice and clean before pushing the sensors home. I had to trim the foam back a little on the sensors on mine to ensure it was a snug tight fit against the bumper skin. Once all sensors are in place, tidy the wiring and reassemble the bumper. I strongly recommened you lubricate the foam that the aluminium goes back to, or you will struggle to get the clips back on.
Step 4. Bumper wiring and refit

Firstly, find a suitably stiff piece of wire with which to pull through the sensor wires into the boot. There are a couple of options as to where, I chose to wire it into the boot via one one the bolt mounting points. Once all cables are through, then its time to pop the bumper back on a-la Haynes refit is the opposite of removal. It did need a bit of tweaking in order to get it sitting right, but it went back fairly easily in the end. The live feed for the reverse light is the GREEN wire as shown in the picture, attatch the live wire from the control box to this, and the other to any neutral wire.

Now plug all sensors in, along with the beeper and give it a whirl before you tidy it all up. He placed the beeper under the back shelf, and the control box was stuck behind the carpet near to the boot wiring loom.He is so clever and carefull to do it.A backup sensor fitting is well done by him now!!
