  • Patent number: 10443561
    Abstract: A hydroelectric power generation device is structure to utilize water flowing to generate electrical power that could be supplied to a bathroom installation and is generally made up of a functional main body, a battery assembly, and a power generation module. The functional main body has two opposite sides each including a mounting end formed thereon. The functional main body forms therein a receiving chamber. The power generation module includes a stator and a rotor. The rotor is coupled, in a manner of being rotatable, to an axle, which is coupled to a vane wheel. Water flowing into the device drives the vane wheel and the rotor to rotate simultaneously so that magnetic interaction between the rotor and the stator generates electrical power that is supplied to a sensor controlling supply of water flow. A sleeve is fit over the axle for correcting and stably supporting the axle in rotation.

  • Patent number: 10382742
    Abstract: An active camera system images successive frames of a scene utilizing an array of detectors configured to produce a response having a linear relationship to a number of incident photons. Multi-frame capture is utilized with differentiated frame illumination for successive frames. Frame processing allows the camera to produce, at the pixel level, different image intensities representing maximum signal intensity, ambient signal intensity, and object signal intensity. The linearized response of detectors in the lighting-invariant image sensor is used to establish non-attenuated signal strength that enables shadow removal and glare removal for one or more of the image signals. Embodiments of a lighting-invariant image sensor may be used in Autonomous and Semi-Autonomous Vehicle Control/Assist Systems.

  • Patent number: 9681996
    Abstract: A wetness sensor includes a self-supporting substrate and an electrically conductive trace carried by the substrate. The trace is patterned to provide at least a portion of a tuned RF circuit, which may be disposed on only one side of the substrate and characterized by an impedance or resistance. The trace is not self-supporting. The substrate is adapted to dissolve, swell, or otherwise degrade when contacted by a target fluid. Such degradation produces a drastic change in the operation of the RF circuit, which can be interpreted by a remote reader as a “wet” condition. 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: 8754771
    Abstract: The invention relates to a method, a device and a system for preventing false alarms in a theft-preventing system comprising a magnetic field for detecting at least one metal object in a first detection zone and means for determining a time-difference; said method comprising the steps of detecting a first change in a parameter indicative of the magnetic field in said first detection zone; detecting a second change in the parameter indicative of the magnetic field in said first detection zone; determining a time-difference between the detection of said first change in said parameter and the detection of said second change in said parameter; and performing an action based on said time-difference. In this way, false alarms due to a metal detector falsely detecting for example movement of metal-doors in a first detection zone may be reduced/eliminated. Additionally, the false alarms due to an opening and/or closing of a door with metal parts acting as an active tag may be reduced/eliminated.

  • Patent number: 8712679
    Abstract: A system and methods for building a map non-invasively (i.e. mapping of occluded and non-occluded obstacles) based on a small number of wireless channel measurements. Approaches for building an obstacle map are based on coordinated space, random space and frequency sampling, such that the sparse representation of the map in space, wavelet or spatial variations, are exploited in order to build the map with minimal sensing.

  • Patent number: 8681005
    Abstract: A technique for operating a Radio Frequency Identification, RFID, reader with motion detection includes detecting a motion in proximity to the RFID reader, and triggering the RFID reader to read any tags in proximity to the RFID reader in response to detecting a motion in proximity to the RFID reader. Detecting a motion can also generate a change in digital signage, or communicate information about read tags to a local area network. Operating this system only when motion is detected saves battery life.

  • Publication number: 20140028457
    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: 8629771
    Abstract: A proximity sensor can be used with a device that relies on GPS signals or other radio-frequency (RF) signals. The proximity sensor can be used to determine if the signals are being deliberately blocked by an object such as metal foil placed near it. The sensor includes an oscillator 2, a directional coupler 4 and an antenna 8. A third port 6c of the directional coupler acts as a coupled port when RF power that has been transmitted by the antenna 8 is reflected back to the antenna by a blocking object. The reflected RF power passes along a main line of the directional coupler 4 and a proportion is coupled to the third port 6c. A detector provides an alert if the magnitude of the power of the transmit signal that is reflected back to the antenna 8 in the form of a receive signal exceeds a threshold.
