Abstract: A system and a method remotely monitors electrical and/or mechanical equipment where a user may interactively alter the operation of a piece of equipment remotely. As the operation of a device may be altered remotely, a corresponding resource-consumption amount may also be remotely controlled and adjusted. An embodiment of the present inventions is directed to remotely adjusting, or causing the remote adjustment, of the use, state, parameters or characteristics of a device, process or both, for reducing resource demand and/or adding to the resource supply. The remote adjustment may originate from a user associated with the devices, a supplier of a resource for operation of the devices, a utility industry participant, a third party, government entity, a trader or any other entity. The adjustment of resource-consumption may be based on a triggered event/condition, a predetermined schedule or other defined scheme.

Abstract: A snow and ice melt control system is provided to melt snow and ice from a slab, a temperature sensor means are provided at the input and output from the slab, and a differential temperature is generated reflecting the condition of the slab in respect to the ambient temperature. A controller is provided to adjust the amount of heat and heated fluid flowing to the slab to actively respond to environmental conditions to more efficiently melt snow and ice on the slab.

Abstract: In a thermostatic control system a solid state motor controller is provided by reproducing a potentiometer tracking with a CPU producing appropriate complimentary square wave signals having the duty cycle thereof proportional to a sensed temperature. The square wave signals are fed to circuits which are disposed across two output resistors and the effective resistance of the two resistors are varied in response to the duty cycle.

Abstract: An integral thermostat and digital clock is disclosed which operates with conventional two-wire systems connected between the thermostat and remotely operated relay. The two wires are used to carry a control signal from the thermostat to the remote relay and power to the integral unit for providing timing signals and power. The integral unit has a combined display which can be used for the time of day or temperature and separate day and night time settings are provided for changing the control of the thermostat according to the users' needs.
