  • Motion feedback
    Patent number: 9201545
    Abstract: A user input to a system is processed by receiving reflections of signals from a moving input object. Information relating to the direction of movement of the input object and information relating to the speed of the input object are determined from the reflections. Continual sensory feedback is provided to the user, controlled by a parameter that is repeatedly updated based on the direction and speed of the input object. When no new determination of information relating to the speed or direction of the input object has been made since a previous update, a time-dependent change is made to the parameter.

  • Multi-range object location estimation
    Patent number: 8681585
    Abstract: Estimating the impulse response of a channel by providing an initial signal (20); applying a time-shift function to the initial signal (20) to produce a transmit signal (36); transmitting the transmit signal (36); receiving a received signal; calculating an impulse response from the received signal as if the received signal had been produced by the initial signal; and using the impulse response to distinguish between received signals arising from reflections from objects (6) at different ranges.
