  • Patent number: 10754476
    Abstract: A close-range motion detector has at least one transmitter, at least one receiver, and at least one more transmitter or receiver. The transmitter(s) transmit, and the receiver(s) receive signals in one of the ultrasonic or mm-wave ranges. Multiple transmitters or receivers are spaced apart from one-another along a plane, and transmission of a signal takes place at a known time. Echos of the signal that bounce of a scatterer are received and digitized during a receive window, and the time-of-flight is determined using CAF. Time scaling may be determined as well, and may be determined using CAF. The determined time-of-flight is used to determine an X-Y-coordinate for the scatterer, and its motion (e.g., velocity) can be determined, which are output. In an embodiment, a such a close-range motion detector can be implemented on the side of a smart-watch, making a virtual writing surface on the back of a user's hand.

  • Patent number: 10707575
    Abstract: Optimizations are provided for controlling an amount of radiated power (i.e. spectral flux density) that is being transmitted to a particular location. To that end, one or more antennas are used to transmit a power signal. Then, position information for each of those antennas is determined. Additionally, environmental information for the environment in which the antennas are operating is also determined. Also, an antenna radiation pattern for each of those antennas is also determined. Thereafter, how much power is radiated to a particular location is controlled so that the power never exceeds a certain threshold value. This control is achieved by dynamically adjusting the transmit power of the antennas based on the information obtained from the position information, the environmental information, and the antenna radiation pattern information.
