Abstract: A power meter includes a voltage sensor input port configured to receive one of single phase AC voltage and three phase AC voltage values. The power meter further includes a current sensor input port configured to receive one of single phase AC current and three phase AC current values. The power meter further includes a bus connector adapted to be coupled to a data bus. The power meter further includes a module connector adapted to be coupled to a module bus. The power meter further includes a timer for producing a digitizing clock. The power meter further includes a microprocessor.

Abstract: Methods and apparatus provide for at least one relay with contacts transitioning from: an OFF state to an ON state in response to an ON-pulse of current through a coil in a first direction; and the ON state to the OFF state in response to an OFF-pulse of current through the coil in a second, opposite direction. A driver circuit operates to produce the ON-pulse through the coil of the relay in response to a control signal commanding the ON-state of the contacts; produce the OFF-pulse of current through the coil of the relay in response to a control signal commanding the OFF-state of the contacts; and produce the OFF-pulse of current through the coil of the relay in response to a loss of operating potential across the pair of operating power nodes.

Abstract: An intelligent, modular server management system for coupling a series of remotely located computers to one or more user stations allowing for selective access of the remotely located computers. A centralized computer matrix switching system is provided to enable a computer user station to access and operate a remotely located computer in a stable environment and transmit analog signals through the switching system over an extended range. The centralized computer matrix switching system receives the input from the computer user station or the remotely located computer, including the keyboard, video monitor and mouse signals, and transmits the signals as though the computer user station was directly coupled to the remotely located computer.

Abstract: An apparatus for providing I/O support to a computer system and a method of use thereof is disclosed. The apparatus in accordance with the present invention includes an internal control element located within the apparatus. The control element allows the apparatus in accordance with the present invention to relinquish ownership of the associated I/O devices for the purpose of being used by another computer. Accordingly, through the use of the apparatus in accordance with the present invention, expensive KVM switches and cabling, along with the accompanying I/O devices, are no longer needed to provide I/O support for computer networks. A first aspect of the present invention provides an apparatus for providing I/O support to a computer system. The apparatus comprises an I/O device and an internal control element coupled to the I/O device for relinquishing ownership of the I/O device from the apparatus to the computer network.
