    Abstract: A user input detector for a mobile device is described having an ultrasound demodulator having an input for receiving an ultrasound signal reflected from a user and an output for outputting a demodulated ultrasound signal; a gesture processor comprising: a time-frequency processing module configured to generate a time-varying ultrasound-image spectrum from the demodulated ultrasound signal; an image-feature extraction module configured to extract micro-doppler features from the time-varying ultrasound image spectrum; a feature selection module configured to select and compress the extracted micro-doppler features; and a gesture detection module configured to compare the selected micro-doppler features with a known feature set and to output a detected gesture based on the comparison. The user input detector may be incorporated into a mobile phone for example to provide an always on low power control mechanism for the mobile phone by recognizing user gestures and executing control commands in response to those user gestures.

    Abstract: One example discloses an acoustic pairing device, comprising: an acoustic processor configured to receive a first acoustic signal and a second acoustic signal; a signal comparison module configured to identify a propagation delay or amplitude difference between the first and second acoustic signals; and a pairing module configured to output a pairing signal if the propagation delay or amplitude difference is between a first value and a second value. Another example discloses a method for acoustic pairing between a first device and a second device, executed by a computer programmed with non-transient executable instructions, comprising: receiving a propagation delay or amplitude difference between a first acoustic signal and a second acoustic signal; pairing the first and second devices if the propagation delay or amplitude difference is between a first value and a second value.

    Abstract: A method of controlling a mobile device is described, the method comprising: receiving a time varying current or voltage of a signal generated on the terminals of an acoustic transducer of the mobile device, the time varying current or voltage being generated in response to a tapping and/or sliding motion on a surface of the mobile device performed by a user; comparing the time varying signal characteristics with a set of predetermined signal characteristics; and generating at least one user command in dependence of the comparison. The mobile device may reliably detect complex user commands using an acoustic transducer.
