Abstract: A power charging module includes a controller, a charging port, and a temperature sensor. The charging port delivers power to an external device plugged into the charging port. The temperature sensor provides a sensed temperature to the controller. A standard maximum power output is delivered to the charging port if the sensed temperature is categorized in a nominal thermal condition range, a modified maximum power output is delivered to the charging port if the sensed temperature is categorized in an intermediate thermal condition range, and power output to the charging port is discontinued if the sensed temperature is categorized in a critical thermal condition range.

Abstract: A method is provided that includes selectively engaging impedance circuits one at a time from a plurality of selectable impedance circuits in-line with a communication channel. Each of the plurality of selectable impedance circuits includes a hybrid circuit responsive to a modem and to the communication channel. The method further includes determining a performance characteristic for each of the impedance circuits and selecting one of the plurality of selectable impedance circuits for transmission based on the respective performance characteristic.
