  • Patent number: 8025428
    Abstract: An assembly of light emitting diodes for a streetlight or the likes comprises a first board having a first matrix of light emitting diodes (LEDs) mounted thereon defining a first light projection plane and at least another board having a second matrix of LEDs mounted thereon defining a second light projection plane. The other boards are mounted to the first board so as to define an angle therebetween. The LEDs can be mounted to the boards so as to independently define and angle therewith. They can also be oriented towards privileged directions. The present assembly allows providing a more uniform light distribution.

  • Patent number: 7181517
    Abstract: The modular master control unit of the telecommunications power system communicates via a data bus with the associated modular rectifier units, distribution unit(s) and battery connection unit(s) to collect operating state information from the neuron processors of those units and store that information in a database. The master control unit also controls the operation of the associated modular units by supplying operating state information, based on values stored in the database. The user interface manager module provides local user interface control over the system by allowing the user through a local display screen and touch pad to read from and write to the database. By downloading an applet to a remote computer running a web browser, the user interface manager allows users at remote locations to perform the same control and monitor functions as a user at the local site. The applet runs within the standard browser and communicates with the user interface manager using TCP/IP protocol.

  • Patent number: 6885879
    Abstract: A telecommunications power system includes a power bus and a battery module with a plurality of batteries. A contactor connects the batteries to the power bus. A distribution module and a plurality of rectifier modules are connected to the power bus. A plurality of loads are connected by the distribution module to the power bus. A controller disconnects the batteries using the contactor when a voltage of the batteries falls below a low voltage disconnect threshold when AC power is lost and/or the rectifier modules fail. The controller minimizes current surge and high voltage transients when the rectifier modules begin providing power and the contactor closes to reconnect the batteries to the power bus. To minimize current surge and high voltage transients, the controller lowers a voltage of the rectifier modules to the voltage of the batteries before the contactor reconnects the batteries to the power bus.

  • Patent number: 6650967
    Abstract: An automated battery configuration system for a telecommunications power system includes at least one rectifier module, a controller and at least one backup battery. A database system is associated with the controller stores a plurality of records that include a plurality of backup battery parameters. A user interface that is associated with the controller receives user-provided input of at least one battery specifying parameter. The user interface communicates with the database system to retrieve a selected one of the records based on the battery specifying parameter. The controller communicates with the database system and employs at least one of the parameters of the selected record to alter an operating setting of the telecommunications power system. The battery specifying parameters include a manufacturer designation and a model designation of the backup battery.

  • Patent number: 6609081
    Abstract: Processor-implemented monitor and control modules gather operating data from the rectifier units, battery connection units and power distribution units. From these data, statistical operating data are calculated and stored in a database managed by the resident processor within the power system control unit. The system expansion analysis module analyzes the statistical data in view of a set of predetermined warning and alarm threshold parameters, which may be factory specified or user settable. If an alarm or upgrade condition is detected, the system expansion analysis module generates an upgrade notification that is optionally sent in a variety of forms including local audible or on screen notification, remote alarm through network connection to a remote computer, via internet web browser and e-mail message. The system can also optionally initiate automated order processing to place orders for upgrade or expansion equipment and installation services.

  • Patent number: 6560123
    Abstract: An assembly for mechanically mounting and providing electrical connections to overcurrent protection devices having first and second male power plugs includes a non-conductive main structural support member having a plurality of plug passageways formed therein and one or more load busbar modules mounted thereon and also including a plug passageway formed therein, to enable the male electrical plugs to mate with sockets disposed in a conductive line busbar member mounted on said support member and with a socket disposed in a load busbar member included in each load busbar module. Each load busbar module includes a non-conductive housing and a releasable cover within which is mounted the load busbar member. A printed circuit board substrate is preferably also mounted to said support member to provide a support surface for auxiliary signal clip connectors disposed on one side of the substrate.

  • Patent number: 6281602
    Abstract: A telecommunications power system according to the invention includes a power bus and a plurality of batteries that are connected to the power bus. A distribution module is connected to the power bus. A plurality of loads are connected to the distribution module. A plurality of rectifier modules are connected to the power bus and at least one AC power source. A generator provides backup AC power to the rectifier modules when the AC power source is interrupted. A controller is connected to the rectifier modules and the generator. A controller includes a battery recharging control module that allows the user to select a first mode of operation that allows the generator to recharge the battery when the generator provides the backup AC power. A second mode of operation prevents the batteries from recharging when the generator provides the backup AC power.
