Abstract
The subject matter disclosed herein relates to dynamically determining DC-offset used for proximity sensing of a mobile device.
Claims30
A method comprising:
- receiving one or more signals from one or more inertial sensors on a mobile device;
- receiving a received power signal from a distance sensor on said mobile device;
- and
- estimating a DC offset component of said received power signal based, at least in part, on said one or more signals received from said one or more inertial sensors.
1 more element
A method comprising:
- receiving a received power signal from a distance sensor on a mobile device;
- detecting a user event on said mobile device at a time;
- and
- estimating a DC offset component of said received power signal at said time responsive to said user event.
1 more element
The method of claim 8, wherein said user event comprises a camera shutter click.
A mobile device comprising:
- one or more inertial sensors to provide signals representative of orientation of said mobile device;
- a distance sensor to provide a received power signal;
- and
- a DC offset component manager to estimate a DC offset component of said received power signal based, at least in part, on said signals provided by said one or more inertial sensors.
1 more element
An apparatus comprising:
- means for receiving one or more signals from one or more inertial sensors on a mobile device;
- means for receiving a received power signal from a distance sensor on said mobile device;
- and
- means for estimating a DC offset component of said received power signal based, at least in part, on said one or more signals received from said one or more inertial sensors.
1 more element
The apparatus of claim 25, wherein said DC offset component is estimated to comprise substantially said received power signal.
A mobile device comprising:
- one or more inertial sensors to provide signals representative of orientation of said mobile device;
- a distance sensor to provide a received power signal;
- and
- a special purpose computing device adapted to estimate a DC offset component of said received power signal based, at least in part, on said signals provided by said one or more inertial sensors.
1 more element
An article comprising:
- a storage medium comprising machine-readable instructions stored thereon that are executable by a special purpose computing device to:
- receive one or more signals from one or more inertial sensors on a mobile device;
- receive a received power signal from a distance sensor on said mobile device;
- and
- estimate a DC offset component of said received power signal based, at least in part, on said one or more signals received from said one or more inertial sensors.
