摘要:
In a vehicular anti-theft security system which includes a theft detection sensor (2, 3) that detects an abnormality of the vehicle associated with vehicle theft, and performs a theft preventing operation when the theft detection sensor detects the abnormality, an altitude measuring device (1) is provided for measuring the altitude of the vehicle, and a controller (5) restricts the theft preventing operation in the case where the altitude measuring device (1) observes a specified change in the altitude of the vehicle within a specified period of time when the theft detection sensor detects the abnormality. Selected Figure: FIG. 2
摘要:
A moving object detection system includes a transmitter, a receiver, a detector, an oscillation means, a switch and a controller. The oscillation means is configured to generate a first oscillation signal having a first frequency, and a check signal having a check frequency that is different from the first frequency. The switch is configured to supply the first oscillation signal or the check signal to the detector. The controller has a monitoring phase and a check phase and is configured: to supply the first oscillation signal to the transmitter through the switch at the monitoring phase; and also to supply the check signal to the detector through the switch at the check phase.
