  • Patent number: 9729958
    Abstract: A headset providing audio input and output for a mobile device includes a microphone and speaker. An RF transceiver performs wireless communication with the mobile device. One or more buttons are configured for push operations to control operation of the headset, the mobile device, or both. A processor is configured to process a signal input from the microphone and output the processed signal to the RF transceiver, process a signal received from the RF transceiver and output the processed signal to the speaker, and process a signal input according to the push operations of the one or more buttons. At least one of the buttons is configurable to actuate a selected function. A memory associated with the processor stores program instructions for executing a plurality of functions, wherein the selected plurality of function is selected in response to user input via a user interface on the mobile device.

  • Patent number: 9503802
    Abstract: The present invention relates to a controller for controlling an electronic device. The invention may e.g. be used to control a headset or another electronic device connected to the controller. The controller (1) comprises an elongate controller body (3) having a first body end (4) and a second body end (5). The controller body (3) comprises an elongate rotatable body section (10) adapted to be rotated by a user about a longitudinal axis (11) extending through the first body end (4) and the second body end (5). The rotatable body section (10) has a radially outer side surface (12) extending between a first section end (13) near the first body end (4) and a second section end (14) near the second body end (5). The rotatable body section (10) has a size and shape allowing the user to rotate the rotatable body section (10) about the longitudinal axis (11) by performing a rolling action using three or more fingers (21, 22, 23).

  • Patent number: 9479626
    Abstract: The present invention is directed to, amongst other things, detection of the causes of communications failures primarily between a base station and wireless headset and then taking action in response thereto, such as notifying the user wearing the headset. The wireless telephone sound interface device (2, 22) is characterized in that the device controller (41) further is adapted to estimate a disconnection cause for said disconnection and to control the electronic circuit (42-49) in dependence on the estimated disconnection cause. This may allow the wireless telephone sound interface device (2, 22) to avoid superfluously alerting the user of a disconnection deliberately caused by the user and may thus aid in reducing daily annoyance of the user and/or of colleagues in a working environment.
