Abstract
A base unit includes a sensor calibration function. When a user communicatively couples a consumer electronic device having a sensor to the base unit, a controller at the base unit retrieves a calibration reference value for the sensor and/or a sensor algorithm that utilizes data output by the sensor. The base unit then sends the calibration reference value to the consumer electronic device to set a sensor calibration parameter associated with the sensor and/or the sensor algorithm.
Claims16
A method comprising:
- detecting, by a wireless charging platform, each of a first electronic device and a second electronic device while both are positioned on a charging surface of the wireless charging platform, the first and the second electronic devices each comprising a battery and a sensor;
- communicatively coupling each of the first and the second electronic devices via respective wireless communications to the wireless charging platform;
- receiving, by the wireless charging platform, identification data comprising information identifying the first and the second electronic devices and the respective sensors of each of the first and second electronic devices;
- reading, by the wireless charging platform, a current reference calibration value associated with the sensor of the second electronic device;
- storing the current sensor reference calibration value in the wireless charging platform;
- and
- determining, by the wireless charging platform, the current sensor reference calibration value is applicable to the sensor of the first electronic device and setting a sensor calibration parameter of the sensor in the first electronic device based on the stored current reference calibration value while wirelessly charging the battery of the first electronic device.
