A wearable device, comprising: one or more processors configured to: detect a wear status of the wearable device; and in response to the wear status, allocate resources of the wearable device to one or more functions of the wearable device.

Dynamic resource allocation

Dynamic allocation of operational resources of wearables

This application relates to transfer of digital audio data between a host device and an accessory apparatus that may be connected to the host device via a suitable connector, such as a USB connector. A path selector is operable to establish either a first digital data path or a second digital data path for transfer of digital data. The first digital data path includes a first data bus host and a general purpose digital data interface suitable for bulk data transfer between the first data bus host and the applications processor of the device. This may be a default USB path. The second digital data path includes a second data bus host and at least one pair of second path data interfaces. The second data bus host 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.

Audio transfer

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.

Method and system for an electronic device

This application relates to transfer of digital audio data between a host device () and an accessory apparatus () that may be connected to the host device via a suitable connector (), such as a USB connector. A path selector () is operable to establish either a first digital data path () or a second digital data path () for transfer of digital data. The first digital data path () includes a first data bus host () and a general purpose digital data interface () suitable for bulk data transfer between the first data bus host and the applications processor () of the device. This may be a default USB path. The second digital data path () includes a second data bus host () and at least one pair of second path data interfaces (). The second data bus host () 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.

Systems and methods for digital data transfer between an electronic device and an accessory apparatus removably connected to the electronic device

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.
