Safety device
专利汇可以提供Safety device专利检索，专利查询，专利分析的服务。并且PURPOSE: To enhance the quality of the safety device necessary for safe driving of vehicles, by giving the distances between one's own vehicle and the vehicles located ahead, behind and at the sides thereof as quantitative values to the driver.
CONSTITUTION: A projector has an infrared ray lens 22 and other parts disposed in the front face and an infrared ray emitting diode 21 provided in the rear part thereof. The infrared ray emitted from the light emitting diode 21 is modulated by a pulse transmitter 23 and a pulse amplifier 25, and is condensed by a condenser lens 22 to be projected as a nearly parallel light 30. The reflected light 31 reflected by the vehicle located ahead is selected only of the central light of the light projected by a band pass filter 32, and is transformed into an electric signal, so that risk of danger is judged in a judging circuit 41. At this time, in order to prevent malfunction of the own vehicle due to projected light from the safety devices mounted on vehicles running ahead or in opposing direction, it is necessary to take proper measures to very the central wavelength of the projector with respect to the forward monitor safety device and the backward monitor device.
