  • Gesture control
    Patent number: 10459525
    Abstract: A method of operating a touchless user interface on an electronic device is disclosed. The electronic device is configured to determine information regarding the position and/or movement of an input object. The method has the steps of: deciding that an engagement gesture has been performed; deciding that a related input gesture has been performed; and carrying out an operation on the device on the basis of the input gesture only if the engagement gesture has been recognized and if the input gesture is one of a subset of possible input gestures determined by the engagement gesture.
    Type: Grant
    Filed: July 9, 2015
    Date of Patent: October 29, 2019
    Assignee: ELLIPTIC LABORATORIES AS
    Inventors: Guenael Strutt, Joachim Bjørne, Geir Birkedal

  • 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.
