It is a machine that detects changing in blood pressure, heart rate and other body rhythems to detect false statements.
We use the IC1 555 in LPG gas detector to detect the leaking gases.
Yes, you can use a metal detector in the rain if....... The detector is made for underwater use. If the metal detector is made for land use, put a cover over the electronics housing. Many of the top manufacturers sell rain-proof covers. Be sure your headphones are waterproof!
Yep it does.
yes
no
To use the PLL (Phase Lock Loop) as FM detector, you need to know the Free-running frequency.
To use a smoke detector tester spray properly, follow these steps: Press the test button on the smoke detector to ensure it is working. Hold the tester spray about 6-12 inches away from the detector. Spray a short burst of the tester spray towards the detector. The smoke detector should sound an alarm within a few seconds if it is functioning correctly. If the alarm does not sound, replace the batteries or the detector itself.
motion detector
No.
NO why would there be
Polymorph is used as a lie detector.
VG2 Immunity referrers to the ability of a radar detector to keep you from being seen by the VG2 radar detector detector. The VG2 radar detector detector is used by police agencies in the U.S. and countries (Canada for one) where the use and or possession of a radar detector is illegal. The authorities use the VG2 to detect whether or not you are using a radar detector. The VG2 detects the electronic emissions of non-stealthed radar detectors allowing law enforcement to pull over offenders, ticket them and (in Canada and some U.S. states) confiscate the detector. Radar detectors that use Shadow Technology™ are purported to be shielded in such a way that the amount of detectable emissions allowed to escape the detector are not enough to trigger the VG2 radar detector detector thus making them "immune" to the VG2. It should be noted that in Canada i believe that use and/or possession of a radar detector is considered "conspiracy to speed" and carries a hefty fine and includes the confiscation of the radar detection unit. Edit: In Canada, there are certain Provinces were radar detectors are illegal. You are allowed to use them in BC, Alberta, and Saskatchewan.
