  • Patent number: 11284484
    Abstract: A system for setting the light level in one or more lighting fixtures connected to a control device such as a wall switch or occupancy sensor using only the conventional power wires. The conventional switch is used to turn power on and off to controlled circuits but also to send level setting sequences to special modules installed in the lighting fixtures and connected to the conventional 0-10V dimming connections. The special modules are connected only to the low voltage 0-10V dimming connections with no connections to the power line or neutral circuits.

  • Patent number: 11263320
    Abstract: Example implementations relate to updating firmware. For example, a system according to the present disclosure may include a printing device and a computing device. The printing device may be on a network. The printing device may detect an intrusion against the printing device. The computing device may be on the network. The computing device may receive a broadcast reporting the intrusion directly from the printing device. The computing device may request, responsive to receiving the broadcast, an updated portion of a firmware code image for the computing device.

  • Patent number: 10251228
    Abstract: An add-on electronic load that, when inserted in parallel with a LED fixture, which is controlled by a triac-based dimmer, will improve dimming performance by reducing flickering and/or achieving a lower stable dim level, while dissipating an amount of power that can be safely dissipated if said add-on load in installed in a single-gang wall box behind installed said dimmer.

  • Patent number: 9293918
    Abstract: An electrical control system consisting of two or more electrical transmitting devices each capable of transmitting synchronized messages consisting of electrical pulses to devices connected to one or more of the three phases of the AC power lines in a typical three phase power system. The synchronized transmitters are each connected to neutral and to one or more of the three phases, A, B, and C, or across two of the phases, of different circuit breaker panels in a typical three phase power system, and are capable of transmitting messages to one or more of the three phases. The transmissions from the two or more transmitters are synchronized such that the transmitted pulses from each transmitter are transmitted at the same time to produce a message that can be received correctly at any receiving device connected to any of the connected circuit breaker panels.

  • Patent number: 8294556
    Abstract: Circuits and methods for transmission of digital data between two or more devices via powerline particularly suited for use in high attenuation, high noise commercial/industrial powerline environments, including transmission of pulses generated by a capacitor charged in the positive half cycle of the sine wave and discharged during the negative half-cycle, placing the pulse at one of two predetermined signal timing positions related to zero voltage crossing points or to previously transmitted pulses so that the pulses are substantially in the powerline temporal quiet zone near zero crossing and so that the powerline voltage at the time of the pulse is additive to the capacitor voltage.
