    Abstract: Embedded electronics (102) are operated under normal operating conditions, with power being supplied to embedded electronics via a power source (205). Heat is generated via the normal operation of the embedded electronics (102), and a voltage (117) is generated via thermionic emission from the heat. The voltage (117) that is generated is supplied to the power source (205) to help power the embedded electronics (102).

    Abstract: An antenna switching system for handling high traffic sectors in a cellular radiotelephone system. The system switches the cell's base station transmitters (210) to sectors that have more mobile traffic than they can handle. The additional transmitters (210) increase the number of frequencies in the overloaded sector, thereby allowing a greater amount of mobile traffic to use the cell.

    Abstract: Cellular radiotelephone communication system cell site equipment has a radio frequency transmitter (240) operating as one signal frequency source and a first and a second signal combiner device (282) tuned to a first and a second signal frequency, respectively, each signal combiner device (282) having resonant cavity means for isolating a signal frequency source from other signal frequency sources. Each signal combiner device (282) has coupling means (210) for coupling the isolated signal frequency source to a respective common transmitter output. The system further comprises a radio frequency switching means (230), operatively coupled to the radio frequency transmitter (240), the first signal combiner device (282) and the second signal combiner device (282), for coupling the radio frequency transmitter (240) to either of the first and the second signal combiner devices (282).
