  • Method and apparatus for expanded temperature operation of a portable communication device
    Patent number: 9749740
    Abstract: A method and apparatus for operation of a remote speaker microphone over an expanded temperature range. By monitoring a temperature of the communication device, a temperature sensitive microprocessor can be disabled above a predetermined extreme temperature, thereby allowing control of an audio path of the communication device to be modified. Microphone and speaker signals of the communication device can be switched or rerouted to an electronic path capable of operating above the predetermined extreme temperature for expanded operation while previous microprocessor controlled digital and analog audio circuits are shut down.
    Type: Grant
