Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques include determining the temperature and process speed of chips used in communications devices. The systems and techniques include measuring the output of ring oscillators embedded in the chips, and calculating the temperature and process speed therefrom.

Abstract: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve an efficient power source for prolonged battery life. The power source may include first and second batteries, and a power management module configured to operate each of the first and second batteries in a pulse current discharge mode while supplying continuous current to a load.

Abstract: In general, the disclosure is directed to techniques for reducing power consumption within computing devices, such as wireless communication devices. A device dynamically adjusts the CPU clock frequency based on CPU load in order to reduce power consumption. The device monitors the load of the CPU using a number of sample interrupts. The device determines whether to adjust the clock frequency based on the monitored load of the CPU. In general, the device increases the clock frequency when the load of the CPU is high and decreases the clock frequency when the load of the CPU is low.
