Abstract: An operating method for an electronic device comprising the steps of: monitoring a far-field proximity sensor of the electronic device for far-field detection of a user approach; responsive to said far-field detection, monitoring a near-field proximity sensor of the electronic device for near-field detection of a user approach; and responsive to said far-field detection and/or said near-field detection, providing a visual indication of an interaction zone for the electronic device.

Abstract: This application relates to transfer of digital audio data between a host device (200) and an accessory apparatus (101) that may be connected to the host device via a suitable connector (106), such as a USB connector. A path selector (240, 270) is operable to establish either a first digital data path (201) or a second digital data path (202) for transfer of digital data. The first digital data path (201) includes a first data bus host (103) and a general purpose digital data interface (131) suitable for bulk data transfer between the first data bus host and the applications processor (110) of the device. This may be a default USB path. The second digital data path (202) includes a second data bus host (230) and at least one pair of second path data interfaces (140, 141). The second data bus host (230) does not form part of the applications processor and each of said second path data interfaces comprises a digital audio interface suitable for streaming of audio data. The path selector selectively establishes the first data path for bulk digital data transfer or the second data path for streaming of audio data where latency is important.

Abstract: A method of controlling an audio system comprises: receiving an audio signal, and applying a first gain to the audio signal and outputting an amplified audio signal. On receiving a user input to increase the first gain applied to the audio signal, if the first gain is at a first threshold value, the method comprises: receiving an ambient noise signal, processing the ambient noise signal with a second gain value and outputting a noise cancellation signal, and changing the second gain value in response to the user input.
