摘要： The present invention is an alarm system that includes a dual technology motion sensor. The dual technology sensor includes a PIR sensor with a PIR detection pattern and a Doppler microwave frequency motion detector with a detection pattern wider than that of the PIR sensor. The microwave detector's processing circuitry distinguishes motion beyond the PIR detection pattern, and limits the microwave detector's field of view to match the PIR detector's detection pattern. The microwave detector has a transmitting antenna, two receiving antennas, and processing circuitry for processing received signals. The microwave detector's processing circuitry uses phase information from the two receiving antennas to distinguish motion beyond the PIR detection pattern.

摘要： The present invention is a security system and a method for reliably detecting an intruder without false alarms. The security system includes at least three motion detectors and processor circuitry adapted to collect a plurality of location samples and analyze them to determine if a target has transitioned from a first region to a second region, and when the target has transitioned from a first region to a second region, initiating a predetermined action. Each location sample is determined by: detecting motion from a target with each of the three motion detectors, determining the distance to the target for each of the three motion detectors, and triangulating the three determined distances to produce a two-dimensional location. The security system determines if a target has transitioned from a first region to a second protected region by comparing the plurality of location samples to perimeter location data stored in memory. Different modes of operation cause the security system to take different actions before and after the transition, such as generating an alarm or a warning signal. The security system may also include a display to show the location of one or more targets, which may be the intruder or the occupants of the premises.

摘要： A proximity sensor may be used as part of a vehicle blind spot detection system. The sensor is configured to transmit multiple radio frequency (RF) signals of different frequencies, receive reflected RF signals, and supply intermediate frequency (IF) signals. Each IF signal is representative of one of the reflected RF signals, and each reflected RF signal corresponds to a transmitted RF signal that was reflected by an object within the sensor detection region. The sensor uses the IF signals to determine whether an object is within its detection region and its movement direction.
