Abstract:
A videoconferencing network for digital computer workstations that operate on a local area network (LAN) to exchange data. The network includes a signalling local area network (A-LAN), connected to a first port of a plurality of workstations, for transmitting and receiving data signals between selected ones of the workstations and a broadband local area network (B-LAN) connected to a second port of the plurality of workstations, for transmitting and receiving television signals between selected ones of these workstations. Each television signal is transmitted at a selected frequency channel so that no two transmissions interfere. A software program, stored in and operable on the computer of each workstation, generates and receives data messages, transmitted via the A-LAN, to and from the computer of another workstation, respectively. These data messages initiate and control the transmission of the television signals on the B-LAN such that a plurality of television signals are transmitted simultaneously on the B-LAN, with each television signal assigned to a separate frequency channel. The software program in each computer monitors the status of the channel allocations and generates the channel selecting control signals.
Abstract:
Methods of managing electrical power storage can include remotely controlling operation of one of at least two water heating units included in a single water heater, separately from one another, at a customer location in response to a determination that an imbalance exists in a distribution of electricity to a power grid coupled to the single water heater.
Abstract:
A method of managing excess electrical power generation may be provided by remotely controlling operation of at least one of two energy storage devices coupled in series at a customer location in response to availability of generated electricity to the customer location.

A method of managing excess electrical power generation can be provided by remotely controlling operation of one of at least two heating elements included in a single water heater, where the heating elements are controlled separately from one another, at a customer location in response to availability of generated electricity to the customer location.
Abstract:
Two water heaters may be installed in series at a customer location, such that an output of a first (or storage) water heater is coupled to the input of a second (or primary) water heater, the output of which provides hot water to the customer location. During normal operation, only the primary water heater may actually heat water for use at the customer location. However, during periods of excess capacity, the electrical service provider may enable the storage water heater to store the excess electrical power that is generated by operating the power plant at higher output (which may be more efficient). Later, during hours of greater demand, the electrical service provider may disable the storage water heater used to store the excess capacity, whereas the primary water heater may operate normally. However, during the time of greater demand, the storage water heaters may provide pre-heated water to the primary water heater, which in-turn, may need to heat the water less or perhaps not at all.

A method of managing electrical power storage can include remotely controlling operation of one of a plurality of water heating units included in a single water heater, separately from controlling a remainder of the plurality of the water heating units, at a customer location in response to a remotely transmitted indication.
Abstract:
A wireless interface circuit can include an electrical relay circuit that is configured for coupling to a separate wired thermostat circuit that is separately housed apart from the wireless interface circuit, where an input to the electrical relay circuit is configured for coupling to an electrical conductor provided between the separate wired thermostat circuit and the electrical relay circuit. A processor circuit is electrically coupled to the electrical relay circuit and is configured to control a state of the electrical relay circuit based on messages received via a wireless interface from a local system located at a location of a customer of an electrical service provider.
