  • Patent number: 11056597
    Abstract: A photoelectric conversion device includes a photoelectric conversion element formed of a polar material and including no p-n junction, and first and second electrodes provided on the photoelectric conversion element and arranged at an interval. Space-inversion symmetry of a structure of the photoelectric conversion element is broken. The first and second electrodes are each formed of a metal material that generates no substantial potential barrier preventing majority carriers for the photoelectric conversion element from moving from the electrode to the photoelectric conversion element. Light incidence on the photoelectric conversion element without voltage application between the first and second electrodes causes electromotive force to be generated between first and second electrodes, and enables electric current to be continuously taken out from the first and second electrodes.

    Abstract: A passive infrared sensor system for detecting the direction of movement by a warm object includes a passive infrared sensor and a lens having multiple lenslets. Different lenslets may have different lens characteristics, for example, different focal lengths or thicknesses, to produce focused infrared beams of different intensities for the sensor. As a warm object, such as a person or an animal, moves from one location to another in the field of view of the sensor, the infrared energy emitted by the warm object may be focused by different lenslets having different focal lengths or thicknesses, and the sensor may detect different intensities at different times. A processor may estimate the direction of movement by performing pattern matching of the detected intensities with a database of patterns based on actual statistics or simulations of movements by warm objects in the environment monitored by the sensor, or known characteristics of the environment and the sensor.

  • Patent number: 9857227
    Abstract: A flash thermography device for generating an infrared image of a turbine component located inside a turbine. The device includes a flash enclosure having an aperture. A flash source is located in the aperture wherein the flash source generates a light pulse that heats the turbine component. The device also includes an infrared sensor for detecting thermal energy radiated by the turbine component wherein the radiated thermal energy is transmitted through the aperture to the infrared sensor to enable generation of an infrared image of the turbine component. Further, the device includes moveable arm that holds the flash enclosure and infrared sensor wherein the arm is inserted through an opening in the turbine to enable positioning of the flash source and infrared sensor in close proximity to the turbine component.

  • Patent number: 9846091
    Abstract: Certain example embodiments include a press sensor element that includes a piezoelectric layer having a first surface in communication with a first layer, the first layer including a first conductive region, where the first conductive region covers at least a central portion the first surface. The sensor element includes a second surface in communication with a second layer, the second layer including a second conductive region, a third conductive region, and a first non-conductive void region separating the second conductive region and the third conductive region. An area of the first conductive region is configured in size relative to an area of the third conductive region to substantially reduce a thermally-induced voltage change between two or more of the first, second, and third conductive regions responsive to a corresponding temperature change of at least a portion of the piezoelectric layer.

  • Patent number: 9797779
    Abstract: Graphene and ferroelectric materials are used as tunable sensors for detecting and measuring radiation, such as infrared radiation. The low absorption and reflectance of graphene and interconnected graphene networks, for example in the infrared, are exploited for use in such tunable sensors. The active layer makes use of a unique property of ferroelectric materials, known as the pyroelectric effect, for measuring the intensity of impinging radiation. Using graphene electrodes may offer a significant increase in sensitivity, tunability and mechanical flexibility of sensors, such as infrared sensors. In one method, intensity of radiation is measured using variations in the doping level of the graphene electrode.

  • Patent number: 9735708
    Abstract: Technologies are generally described for generating electrical power from piezoelectric power. Example devices/systems described herein may use one or more of a piezoelectric device, a plurality of solid particles, and/or a container. In various examples, an electrical power generator apparatus is described, where the apparatus may be configured to provide an electrical signal upon application of a mechanical stress to the piezoelectric device. Some example apparatus may also be configured to contain the plurality of solid particles in the container, which may be coupled to at least a portion of a surface of the piezoelectric device. When a mechanical force is exerted on the plurality of solid particles, the plurality of solid particles may be effective to receive at least a portion of the mechanical force and responsively apply the mechanical stress to the piezoelectric device.

  • Patent number: 9715769
    Abstract: A process for determining a stationary state of a vehicle includes providing a camera and a control having an image processor. Vehicle data is provided to the control by an accelerometer of the vehicle and by at least one of (i) a transmission sensor of the vehicle and (ii) a speed sensor of the vehicle. A determination that the vehicle is stationary is made when at least one of (i) the control determines a jerk value that is approximately zero for a selected duration of time and the control receives vehicle data indicating that the speed of the vehicle was approximately zero for the selected duration of time and (ii) the control determines a jerk value that is approximately zero for a selected duration of time and the control receives vehicle data indicating that the transmission of the vehicle was in ‘Park’ for the selected duration of time.
