Electrical power is dynamically managed a power source a load. A control switching system has a plurality of monitor nodes, a control switch having two switching states, and an electrical power storage cell connected to the power source in one of the switching states for storing voltage, and operative for discharging the stored voltage to the electrical load in the other of the switching states. A programmed controller dynamically monitors operating conditions at the monitor nodes during operation of the electrical load and the power source, and switches the control switch between the switching states in response to the monitored operating conditions for supplying a voltage of a desired waveform shape to the electrical load.

A user is authenticated to operate an electrical device in a network, by encoding an identification symbol with identification data that identifies the user, and by encoding a composite symbol with the identification data and with operating data that enables the electrical device to be operated. The composite symbol is associated with the electrical device to be operated. An image of the identification symbol, and an image of the composite symbol, are captured and compared. The user is enabled to operate the electrical device when the identification data in the composite symbol matches the identification data in the identification symbol.

Portable hybrid applications for AC/DC load sharing includes circuitry for simultaneously using at least one of external AC, internal DC power and/or external DC power. The apparatus also includes an input power receptacle for receiving at least one of AC power and external DC power. A power router inside the apparatus routes at least one of AC power, internal DC power, and external DC power to provide power for an application. An apparatus for providing DC to DC conversion includes a tip and a DC to DC whip connected to the tip. A male plug is connected to the second end of the whip. A buck converter within the male plug converts DC power to a DC power level associated with the whip and transmits the converted DC power along the DC to DC whip to the tip. Alternatively, an internal DC source provides internal DC power.

A multiple bi-directional input/output power control system includes a network of functional blocks housed in a single enclosure, providing DC power to one or more DC loads, and providing control and internal pathways, sharing one or more AC and/or DC power inputs. The system feeds back AC power from the DC power source into an AC input connection, and the fed-back AC power is shared by other AC loads. The system operates at least one alternative source of DC in a dynamic manner, allowing maximization of power generating capability at respective specific operating conditions of the moment.

Electrical power is dynamically managed among one or more power sources and one or more loads. A plurality of monitor nodes is connected to an input terminal connected to each source, and to an output terminal connected to each load. A plurality of electrical power storage cells is connected among the input and output terminals, each cell being capable of storing power from at least one of the sources and being capable of discharging stored power to at least one of the loads. A plurality of controllable switches is connected to the cells. A programmed controller dynamically monitors operating conditions at the monitor nodes during operation of each source and each load, and selectively dynamically controls the switches to interconnect the cells in different circuit topologies in response to the monitored operating conditions.

Electrical power and/or data are distributed to one or more electrical devices, preferably mounted on a structure. A first source module is electrically connected to an electrical power and/or data source. Additional source modules are connected in a daisy chain to the first source module. A plurality of system modules is mounted on the source modules. Each system module is electrically connectable to, and disconnectable from, a module connector of a respective source module. Each system module is removable from the respective source module for replacement without powering down the power and/or data source, and without affecting the data distribution.

An electronic ballast system controls one or more ballasts of HID or fluorescent lamps, which are controlled in an nullon/offnull manner by a ultra low power controller that is isolated for a primary power circuit or derives its very low switch power from the ballast itself. The on/off control provides a near lossless control system. This system may be applied to electronic ballast for operates at fractional power levels corresponding to different lighting intensities and with conventional occupancy sensors. The system may also be applied to other electronically compatible end-use devices and applications.

A DC power system receives AC electrical power and DC electrical power from separate first and second sources simultaneously. The DC power system delivers DC electrical power to an output for use by a load requiring DC power. The DC power system includes a converter to convert AC electrical power to DC electrical power and a power sharing control device to control and distribute the DC electrical power to an output. The first source of DC electrical power includes a storage battery, which provides standby DC electrical power to the DC power system. It also includes a power sharing device, which maintains the storage battery fully charged for use at peak loads, when the DC output electrical power is insufficient to meet the DC load. The second source of DC electrical power is a cogenerator such as a fuel cell, a thermo photovoltaic generator or an internal combustion engine and an alternator for generating and delivering DC electrical power to the power sharing device, while producing and delivering waste heat for use of an external load requiring this heat.
