    摘要： A system for communicating across conventional HVAC wiring is provided. The system includes a communication device having a communication module capable of inducing low power, high frequency current signals into a single control wire coupling, for example, a thermostat with a compressor. The communication module includes a power supply module that draws power sufficient to operate the communication module from the existing HVAC wiring, so as to eliminate any need for batteries or external power sources. A second communication module may be coupled to the single control wire. The second communication module operates as a transceiver sending communication signals to, and receiving communication signals from, the communication module. In one embodiment, the communication module is disposed within a building, for example coupled to an electronic thermostat, while the second communication module is disposed outside the building near the compressor. The communication signals are RF modulated signals between 5 and 50 MHz so as to take advantage of and pass across parasitic capacitances found inherent in transformers or other coils disposed within HVAC loads.

    摘要： A method and system for shedding loads based upon a power system characteristic, such as voltage or frequency, is provided. In one embodiment, a remote party, such as a power generator or utility, transmits a signal to a control device proximately located with a load device. Upon receipt of the signal, the control device measures the power system characteristic for a predetermined time to establish a baseline threshold. The control device then monitors the power system characteristic. When the power system characteristic falls outside the baseline threshold, the control device sheds load. In one embodiment, the loads are prioritized such that the load of least importance may be shed first.

    摘要： A microcomputer controlled coin telephone set prevents coin call fraud and also checks the operational readiness of the telephone set to prevent the acceptance of coins into a hopper for later collection by a coin box unless or until the set is fully functional. Capable of being interrogated remotely, a local memory is used for storing coin deposit information and generating coin deposit signals in order of deposit to a central office. In those instances where the line power drops below that necessary for full operation as a coin telephone, low power sensing circuits convert the telephone to the POTS mode which allows speech and dialing capabilities. Similarly, any type of chute failure, or a full hopper causes the telephone to revert to the POTS mode. While in the POTS mode, any coins deposited in the telephone are returned to the customer.
