  • Patent number: 10600384
    Abstract: An electronic system having an assembly of a plurality of electronic devices each driven by a local power unit and a power sequencer control circuit for controlling the power on or off operation of the local power units. The electronic devices can be for example display units of a display wall. An advantage of such an assembly, e.g. a tiled display or display wall, is that a low level or as little energy as possible is dissipated by the local power units such as DC power supplies associated with the electronic devices, e.g. tiles of a display, and the associated “housekeeping” electronics. A further advantage is a limitation of the inrush current at start-up.

    Abstract: An interlock arrangement allows a floating neutral electrical generator having a receptacle, such as a duplex receptacle, absent GFCI protection to be used to provide electrical power to the electrical system of a home or other building during utility power interruption. The interlock arrangement includes structure to disable or prevent access to the duplex receptacle when the electrical generator is coupled to the power cord used to transfer electrical power from the generator to the electrical system of the building. Thus, the duplex receptacles cannot be used to power electrical devices when the generator is connected to supply power to the electrical system of the building. Conversely, when the generator is physically disconnected from the electrical system of the building, the interlock arrangement exposes or supplies power to the duplex receptacles, and may be configured to close access to the receptacle used for connecting to a building electrical system.

  • Publication number: 20140078686
    Abstract: A stackable communications apparatus comprises modules to be powered on in a sequence. Each of the modules comprises components that perform an individual function or group of functions of the apparatus, each module in the plurality of modules comprising an individual chassis stackable with at least another individual chassis of at least another module in the plurality of modules. The modules comprise at least two modules establishing surface contacts by stacking. The surface contacts maintain, without physical cabling, power connection between the at least two modules. A preceding module in the sequence determines, via a power controller in communication with a power controller of a next module, a power requirement of the next module. The power controller of the preceding module in the sequence enables power to the next module if a remaining power from the preceding module is greater than the power requirements of the next module.

  • Patent number: 8653692
    Abstract: A method and system for managing electrical loads on a standby generator. The method includes utilizing a transfer switch control to selectively shed loads each associated with one of a series of priority circuits. Priority values are initially assigned to each of the electric loads based upon the initial hard-wired connection of the electric loads to a main breaker panel during set up. The control unit of a transfer switch allows the user to reassign priority values to each of the electric loads based upon a user preference. The control unit includes one or more predefined priority assignment programs that can be selected to modify the priority values assigned to the electric loads.

  • Patent number: 8466657
    Abstract: A charge balancing circuit implemented within a charge storage device (cell) in a series connected charge storage unit (battery) made up of a plurality of cells. The charge balancing circuit may utilize a controller to sense the voltage in the cell it is implemented therein and the cells adjacent thereto. If the voltage of the current cell exceeds a threshold voltage and is greater than at least one adjacent cell the current cell can transfer charge to the adjacent cell having the lowest voltage. The transfer of the charge is done with a switching network that extracts current from the current cell and then transfers the current to the adjacent cell having the lowest voltage. The switching network may utilize switches and a current storage device (inductor) to transfer the charge. The controller may activate different switches based on which adjacent cell has the lowest voltage.

  • Patent number: 8415830
    Abstract: A method and system for managing loads powered by a standby generator. The method includes utilizing a transfer switch control unit to selectively shed loads each associated with one of a series of priority circuits. The loads are shed in a sequential order based upon the priority circuit to which the load is applied. Once a required load has been shed, the control unit determines whether any of the lower priority loads can be reconnected to the generator without exceeding the rating of the generator while one of the higher priority circuits remains open.
