Method and apparatus for maximum permissible exposure proximity sensor fault detection

A mobile device for detecting a failure in a maximum permissible exposure (MPE) proximity sensor, comprising:

• at least one memory;
• at least one wireless transceiver;
• the MPE proximity sensor;
• and
• a processor, communicatively coupled to the at least one memory, the at least one wireless transceiver and the MPE proximity sensor, configured to:
• measure an indication of operation of the MPE proximity sensor;
• determine whether the indication of operation of the MPE proximity sensor is less than a threshold;
• in response to a determination that the indication of operation of the MPE proximity sensor is less than the threshold, send a request for user messaging to an application processor;
• and
• issue an MPE proximity sensor failure alert.

A mobile device for detecting a failure in a maximum permissible exposure (MPE) proximity sensor, comprising:

• means for measuring an indication of operation of the MPE proximity sensor;
• means for determining whether the indication of operation of the MPE proximity sensor is less than a threshold;
• means for, in response to a determination that the indication of operation of the MPE proximity sensor is less than the threshold, sending a request for user messaging to an application processor;
• and
• means for issuing a MPE proximity sensor failure alert.

A non-transitory computer-readable medium, having stored thereon computer-readable instructions to cause a processor on a mobile device to:

• measure an indication of operation of a maximum permissible exposure (MPE) proximity sensor;
• determine whether the indication of operation of the MPE proximity sensor is less than a threshold;
• in response to a determination that the indication of operation of the MPE proximity sensor is less than the threshold, send a request for user messaging to an application processor;
• and
• issue an MPE proximity sensor failure alert.
