Circuits, methods, and apparatus for testing media devices. One example provides a test system for testing a number of media players. One or more computers can control the testing of the media players and collect results. Each media player tested may be connected to a computer via an adapter. The adapter may include a connection control circuit and an interface. The connection control circuit may connect and disconnect a power supply to the media player being tested. The voltage waveform produced when the power supply is connected and disconnected may be designed to mimic the voltage waveform produced when a user connects and disconnects a cable or docking station from the media player. The interface may receive commands to provide specific instructions to the media player. The interface may monitor the status and activities performed by the media player and report back to the computer.

Automated portable media device testing system

A thermal manager has a digital filter whose input is to receive raw temperature values from a sensor and whose output is to provide processed or filtered temperature values according to a filter function that correlates temperature at the sensor with temperature at another location in the device. The thermal manager has a look-up table that further correlates temperature at the sensor with temperature at the other location. The look-up table contains a list of processed temperature sensor values, and/or a list of temperatures representing the temperature at the other location, and their respective power consumption change commands. The thermal manager accesses the look-up table using selected, filtered temperature values, to identify their respective power consumption change commands. The latter are then evaluated and may be applied, to mitigate a thermal at the other location. Other embodiments are also described and claimed.
