摘要： The present disclosure is directed to devices and methods for detecting dimming gestures using infrared detection. Infrared signals are detected using a thermal metal-oxide-semiconductor (TMOS) infrared (IR) sensor solution. The TMOS IR sensor is highly accurate and has low power consumptions compared to traditional IR sensors that utilize IR receivers.

摘要： An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data generated by a capture device and an activation signal generated by at least one of a plurality of sensors. The processor may be configured to process the pixel data arranged as video frames, perform computer vision on the video frames to detect objects, perform a classification of the objects, present a control signal in response to receiving the activation signal, determine whether there is a match between the classification and an object class and generate a calibration signal in response to the match. The computer vision may determine which zone that the objects have been detected in. Each zone may comprise a coverage region of one of the sensors. The calibration signal may adjust parameters of the sensors that correspond to the zone with the objects that do not have the match.

摘要： A reconfigurable GPR device for acquiring radar data about a medium includes a radar antenna with a first polarization, a processor unit connected to the antenna, and a casing around the antenna and the processor unit. Further the device includes at least one of a wheel assembly and a direction-determining unit. If present, the wheel assembly includes a holder, a wheel and a wheel rotation sensor. The wheel rotation sensor is connected to the processor unit, and an axis of the wheel is pivotal relative to the first polarization. If present, the direction-determining unit is connected to the processor unit and adapted to determine directional information. The directional information is descriptive of an angle between a direction of movement of the device and the first polarization.

摘要： A terahertz security check method and system may include: a terahertz scanning device collecting a terahertz original image of a human body under test, and sending the same to a central server that identifies the terahertz original image, and determines whether the human body under test carries an article. If so, the image is marked with the position of the article and sent to a monitoring terminal. The monitoring terminal correspondingly marking the position of the article on a pre-stored human body cartoon image, and displaying the terahertz original images before and after marking to monitoring personnel, so that the monitoring personnel determine whether the central server has an identification error; and if so, the monitoring terminal changing a marker on the human body cartoon image, and sending the changed cartoon image to a client of security check personnel for displaying.

摘要： Methods and systems for detection of threats in secure areas are disclosed. Microwaves are transmitted into high traffic areas and are reflected off or transmitted through targets within that area. The resulting signals are detected at receiving antennas which are designed to have a high cross-polarization discrimination (XPD) such that co- and cross-polarizations of the resulting signals are separable for further processing. The receiving antennas of the present invention comprise elliptical antennas with a double-ridged waveguide on the interior and a conically-shaped exterior. This particular design for the receiving antennas allows to technologically obtain an XPD of about 30 dB or more for solid angles measured from a receiving antenna's boresight (the main lobe axis), and formed by rotating the corresponding 30-degree planar angle around the main lobe axis, the solid angles measuring approximately 0.84 sr, in a frequency range between 9.5 and 20 GHz.

摘要： A technique relates to a microwave device. A pump resonator, at a first pump resonator end, is connected to both a dispersive nonlinear element and a first stub. The pump resonator, at a second pump resonator end, is capacitively coupled to a pump port, where the first stub is terminated in an open circuit. A quantum signal resonator, at a first quantum signal resonator end, is connected to both the dispersive nonlinear element and a second stub. The quantum signal resonator, at a second signal resonator end, is capacitively coupled to a signal port, where the second stub is connected to ground.

摘要： Lens systems used in a gigahertz/terahertz imaging system are proposed. Each proposed lens system may include two thin lens elements, spherical or aspherical, in which combined provides gigahertz-terahertz refractive power with a small f-number. The gigahertz-terahertz waves are diverted by the lens systems in such a way that it forms an image of an object, such as a human scale object, on a planar gigahertz-terahertz image sensor. The radius of curvatures, profile, sizes, spacing, and aspherical coefficients of the lens elements may be selected to achieve quality focusing performance. The spacing between the lens elements and the spacing between the lens elements and the image sensor may be adjusted to change both the focal length and the focusing distance to achieve optimum field of view and maximum imaging resolution. The size of the lens may be scaled with the size of the object or the lens aperture stop.
