  • Patent number: 11125856
    Abstract: An apparatus, including processing unit (PU) cores and computer readable storage devices storing machine instructions for determining a distance between a target object and a radar sensor circuit. The PU cores receive a beat signal generated by the radar sensor circuit and compensate for a phase difference between the received beat signal and a reconstruction of the received beat signal to obtain a phase compensated beat signal. The phase compensated beat signal is then filtered to remove spurious reflections by demodulating the phase compensated beat signal using an estimated frequency of the phase compensated beat signal. The PU cores then apply a low pass filter to the demodulated phase compensated beat signal, resulting in a modified beat signal. The PU cores then determine the distance between the target object and the radar sensor circuit using the modified beat signal.

In order to determine the level of a filling material in a vessel, only frequencies within a fundamental frequency interval are used. In this case, the minimal frequency of the fundamental frequency interval is greater than the minimal frequency of the frequency ramp and/or the maximal frequency of the fundamental frequency interval is smaller than the maximal frequency of the frequency ramp. The approach provides a reduction of power peaks in the frequency spectrum of the mean power of fill level measuring devices, which peaks result from times in which the fill level measuring device emits a constant frequency before the beginning of or after a frequency ramp.

  • Patent number: 10417545
    Abstract: A detection device includes a first antenna configured to receive a first radio wave transmitted from an external device, a second antenna configured to receive the first radio wave transmitted from the external device, and transmit a second radio wave to the external device; and a chip configured to obtain a comparison result between a first electromotive force generated by the first radio wave received by the first antenna and a second electromotive force generated by the first radio wave received by the second antenna, and to send the comparison result to the external device through the second radio waive. When the first antenna is disposed closer than the second antenna to a place where the existence of moisture is to be detected, a change of the first electromotive force is greater than a change of the second electromotive force in response to the existence of moisture.

  • Patent number: 10402598
    Abstract: Systems, apparatuses and methods provide for detecting the proximate placement of an external NFC reader to a specific location on a display surface. The display surface can be intended for viewing indicia and enabling interaction with an NFC communication device embedded within the display. A circuit can control an NFC security system that can scan for unauthorized tags affixed to the surface of a display. The NFC security system may be activated by an NFC enabled mobile phone placed proximate to the indicated region for receiving an NFC coded message from the display. An NFC security scan can be performed prior to the mobile phone reading the message from the intended NFC tag in the display. Enabling interactive display modes can allow for making selections indicated on the display or detecting motion gestures across the face of the display.

  • Patent number: 10346950
    Abstract: A system and method of capturing and rendering stereoscopic panoramic content is provided. The system may capture information from a virtual scene to generate a stereoscopic panorama in the form of a stereoscopic cube map. Using the pre-captured cube map, the system may render stereoscopic images during gameplay, image viewing, and/or playback of a three dimensional video. The system may capture camera distance information during capture for use in distortion reduction during image rendering and playback. The system may implement additional distortion reduction measures. Further, the system may use the capture camera distance information to write to depth buffers corresponding to rendered images for use when introducing dynamic gameplay elements into the scene. Additionally, the system may use realistic camera models to simulate human anatomy and reduce distortions associated with simplistic camera models.
