US Classification:

340554, 340541, 3405453

Abstract:

A microwave direction of travel detector and method of detecting the direction of an intruder in a protected region. The microwave direction of travel detector transmits and receives, by a microwave transceiver a microwave signal directed toward a protected area. The microwave return signal is modulated by a moving target to produce a Doppler signal. The received Doppler signal is amplified by a chain of amplifiers having two or more amplifiers coupled to the microwave transceiver. A controller monitors the output of each chain of the amplifiers. The microwave sensor is configured for parallel sampling an amplified Doppler signal output from each amplifiers having a low signal output and each successive chain of the amplifiers a successively higher signal output. The controller determines if there is a direction of travel motion from the intruder and sends an alarm.

US Classification:

340554, 342 28, 367 93

Abstract:

A microwave direction of travel detector and method of detecting the direction of an intruder in a protected region. The microwave direction of travel detector transmits and receives, by a microwave transceiver a microwave signal directed toward a protected area. The microwave return signal is modulated by a moving target to produce a Doppler signal. The microcontroller monitors the output of the amplifier chain and stores the signal and compares it with previously stored signals. If the amplitude is increasing or decreasing over a preset time period, this would indicate that the target it approaching or receding respectively and an alarm would be generated by the microcontroller.

Abstract:

A method of automatically calibrating a motion detector and a motion detector adapted for calibration using the method. The method comprises setting the motion detector to a calibration mode, waiting a preset period of time for the installer to walk to the furthest distance, receiving a Doppler signal generated by motion at the furthest distance from the microwave motion detector within the protected area, measuring an amplitude of the Doppler signal and storing a motion detection threshold for the microwave motion detector. The motion detection threshold is a proportional to the measured amplitude.

International Classification:

G08B 13/18

US Classification:

340554, 340540, 340542, 342 27

Abstract:

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.

Abstract:

A motion sensing method and apparatus includes a housing enclosing a microwave motion sensor including an antenna, and a security system. The antenna may be a patch antenna which includes microwave radiating elements for transmitting and receiving a microwave signal for sensing motion. A reflector is attached to the housing and positioned above the antenna for downward shaping of the microwave signal. The microwave radiating elements together with the reflector provide a radiation pattern where a main beam is transmitted in a direction orthogonal to a surface of the antenna and a sided lobe is transmitted downward in amplitude below the microwave motion sensor. An alarm circuit indicates when the microwave sensor detects motion in armed mode, and a masking circuit indicates when the microwave sensor detects motion in a mask zone when the security system is unarmed. A second sensor may be positioned beneath the microwave motion sensor.
