  • Motion localization based on channel response characteristics
    Patent number: 10109168
    Abstract: In a general aspect, detected motion is localized based on channel response characteristics. In some aspects, channel responses based on wireless signals transmitted through a space between wireless communication devices are obtained. A motion detection process is executed to detect motion of an object in the space based on the channel responses, and the channel responses are analyzed to identify a location of the detected motion within one of a plurality of regions within the space.

  • Function approximation circuitry
    Patent number: 9411756
    Abstract: Function approximation circuitry approximates an arbitrary function F over discrete inputs. Discrete values of the function F are stored in a lookup table (LUT) component for various inputs. An addressing module generates an address from an input. An interpolation factor module generates an interpolation factor from the input. An interpolation module generates an output, which is an approximate value of the function F for the input, from the interpolation factor, and from outputs of the LUT component when the LUT component is addressed by the address.
