Abstract
A personal electronic device is provided with a feature of intelligently adjusting a sampling rate of sensors, such as barometers. Before acquiring a measurement from the sensor, the device checks other hardware for conditions that could introduce noise into the measurement. If the device does not determine that excessive noise is likely after checking the other hardware, the device proceeds to acquire the measurement from the sensor. Otherwise, the device delays the measurement. At the end of the delay, the device may check the other hardware again before acquiring the measurement from the sensor.
Claims20
A device comprising:
- a sensor;
- noise associated hardware;
- and
- one or more processors in communication with the sensor and the noise associated hardware, the one or more processors configured to:
- periodically check the noise associated hardware for noise associated conditions;
- and
- determine to either acquire a measurement from the sensor if the noise associated conditions are within acceptable limits or delay acquisition of a measurement from the sensor if the noise associated conditions are outside of acceptable limits.
A method of periodically sampling a sensor, comprising:
- checking, with one or more processors, hardware other than the sensor for noise associated conditions;
- and
- determining, with the one or more processors, to either acquire a measurement from a sensor if the noise associated conditions are within acceptable limits or delay acquisition of a measurement from the sensor if the noise associated conditions are outside of acceptable limits.
A non-transitory computer-readable medium storing instructions, which when executed by one or more processors, would cause the processors to:
- periodically check noise associated hardware for noise associated conditions;
- and
- make a determination to either acquire a measurement from a sensor if the noise associated conditions are within acceptable limits or delay acquisition of the measurement from the sensor if the noise associated conditions are outside of acceptable limits.
