  • Patent number: 11172561
    Abstract: A microwave sensor device is for detecting activity and for sending and/or receiving a communications signal to/from a second microwave sensor device. A microwave transceiver is used for transmitting a microwave transmit signal and for receiving a microwave receive signal. For motion detection, the microwave receive signal is a reflected version of the microwave transmit signal and the signals are processed to identify first signal characteristics. For communication, the microwave transmit signal is a communications signal for detection at another sensor device. The transmit and microwave receive signals are processed to identify second characteristics. This sensor device detects motion and also transmits and/or receives a communications signal using the same transceiver. In particular, the communications signal is designed to be detected by a remote sensor device in the same way as for motion detection.

  • Patent number: 11041947
    Abstract: A method and system for identifying an object in one space monitored by at least one radar transceiver. The method comprises storing intervals of critical distance values (10) associated with the position of a fixed object upon which a time-varying radio signal shadow may be generated, which may be confused with a moving object. Through successive radar detections, the signals are processed and generate a measurement range profile (40), from which a background range profile (41) is extracted to obtain an object range profile (50). The distance of a possible detected object (60) is determined from the analysis of the object range profile. If the distance of the object (4) is external to the critical intervals (51), the object is classified as valid (55). If the distance is internal to the intervals, the detected object may be a shadow and unless further checks are performed, its presence is not indicated.

  • Patent number: 10902710
    Abstract: In at least one embodiment the present invention relates to a Multiple Input Multiple Output (MIMO) covert terrain following outdoor perimeter security sensor that can detect, locate and categorize intruders as they move in proximity to buried sensor cables. This MIMO cable guided radar utilizes parallel standard leaky coaxial cables with uniform aperture(s) in the outer conductor. RF transmissions from both ends of one cable setup an invisible electromagnetic detection field which couples into parallel receive cables. When an intruder moves within the coupled electromagnetic fields the amplitude and phase of the multiple received signals are altered. Signals received from both ends of each receive cable are processed jointly to detect and locate intruders along the length of the sensor cables. The joint processing of the responses seen from both ends of the cable(s), referred to as End-to-End correlation provides uniform sensitivity along the length of cables without the need for expensive “graded” cables.

Contact of the substrate by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or 1000, and/or may cause the trace to disintegrate so as to provide the RF circuit with an open circuit, and/or may substantially render the RF circuit inoperative.

  • Patent number: 9240113
    Abstract: Disclosed are a method for measuring a acoustic transfer function of a predetermined space to be secured or monitored through a correlation between sound signals acquired from a sound source generating device and a sound measuring device and a method and a system for judging whether there is an intrusion object by using a difference between an initially set acoustic transfer function information and varied acoustic transfer function information by using the method for measuring the transfer function. In the present disclosure, when an object moves or an intrusion object is generated in a predetermined space, intrusion or no intrusion is monitored by variation of the acoustic transfer function varied by the intrusion object even though there is no noise generated by the intrusion object.

  • Patent number: 9030320
    Abstract: A real-time threat detection system incorporating a plurality of sensors adapted to detect radiation across the majority of the electromagnetic spectrum. The system also includes an aided or automatic target recognition module which compares the data from the sensors against known radiation signatures and issues an alert when an anomalous signature is detected. The system further includes an operator station which displays sensor information allowing the operator to intervene. The sensors detect radiation which is normally emitted by persons or other bodies and display areas to the operator where normal emissions are blocked.

  • Patent number: 9024760
    Abstract: An ultrasonic occupancy sensor for detecting presence or absence of an occupant in a space includes an ultrasonic receiving circuit having a synchronous rectifier that allows the circuit to detect small-magnitude ultrasonic waves having a Doppler shift. The sensor comprises an ultrasonic transmitter for transmitting ultrasonic waves at an ultrasonic operating frequency, and a controller that drives the transmitting circuit with complementary drive signals to control the ultrasonic operating frequency. The synchronous rectifier receives the drive signals from the controller and rectifies an amplified input signal to generate a rectified signal, which is filtered by a filter to generate a filtered signal. The controller receives the filtered signal and determines that the space is occupied if the magnitude of the filtered signal exceeds a threshold.

  • Publication number: 20150091728
    Abstract: An improved alarm system for monitoring movement through a passageway defined by opposing sidewalls comprises a lower passage indicator disposed toward the lower ends of the sidewalls, an upper passage indicator disposed toward the upper ends of the sidewalls and a control mechanism configured to sound an alarm if one of the passage indicators indicates passage through the passageway and the other passage indicator does not. In a preferred embodiment, the alarm system is configured as a pool alarm and each passage indicator comprises an emitter/receiver that emits an infrared beam toward an opposing reflector to provide a lower beam and an upper beam. If only the lower beam is interrupted, indicating a child passing through the passageway, the control mechanism will generate an alarm signal. If both beams are interrupted, indicating an adult passing through the passageway, the control mechanism will not generate the alarm signal.

A count of the persons present in the accommodation areas is determined in that, in a radio network which contains a plurality of radio stations arranged spatially distributed in the ceiling, wall or floor, the influencing of the radio field of the radio stations between one another by persons physically present there is evaluated, by a radio tomographic location and detection method. A current count of identifiers which are read by RFID reading devices of RFID transponders is determined, the identifiers being carried by authorized persons. The RFID reading devices are arranged there spatially distributed in the ceiling, wall or floor. Based on the respective counts of personal identifiers and the determined person count, an indicator for evaluating the current security situation in the building is determined.
