    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： This invention pertains to a microcomputer controlled coin telephone set which prevents coin call fraud and performs all of the coin discrimination functions. The microcomputer also checks the operational readiness of the telephone set to prevent the acceptance of coins into a hopper for late collection by a coin box unless or until the set is fully functional.

    摘要： A system for establishing local control of a space conditioning load includes a switch for controlling a flow of energy for a space conditioning load. Control logic is operatively coupled to the switch, for receiving control parameters associated with a direct load control event from a utility provider. The control logic may also measure room temperature based on received temperature signals and determine if a room temperature is greater a comfort temperature range. The control logic may eliminate operation of a direct load control program if the room temperature is greater than or equal to the comfort temperature range. The control logic may log and signal back to the utility provider that the comfort temperature range is exceeded. The control logic may then restore local control of the switch and initiate a temperature setback control to a thermostat for the remainder of the control period.

    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.
