  • Publication number: 20090315668
    Abstract: A power and control system for minimizing home-run power lines to fixtures located throughout a building and wirelessly controlling fixtures according to zones defined irrespective of their wiring. Less “pipe and box” is necessary when branch circuits are not used to define zones. A building may be wired in order to minimize costs, while increasing flexibility and reliability by implementing wireless zone control.

  • Patent number: 6836810
    Abstract: A backplane bus system and related method for increasing the throughput of cPCI-specified backplane architectures. The system includes an interposer card for transforming reflective-wave switching into incident-wave switching. Establishing incident-wave switching on the bus along with careful slot pitch and impedance layout increases the rate at which the voltage amplitude observed by all receivers connected to the bus is sufficient to produce a change of state on the first signal propagation down the bus. Most existing peripherals are configured with transceivers that produce reflective-wave switching. The present system includes an interposer card to transform that switching into incident-wave switching. A preferred transceiver for doing so and that is implemented on the interposer card is a GTLP transceiver. A state machine is employed to regulate operation of the incident-wave switching transceiver. The system may be used to permit implementation of as many as 21 slots on a conventional cPCI backplane.
