  • Publication number: 20190075636
    Abstract: A wall-mountable remote control device may be installed in place of an existing light switch and may be configured to transmit wireless signals to an electrical load device, such as a screw-in light-emitting diode (LED) lamp, to provide control of the electrical load device. The remote control device may comprise an air-gap switch adapted to be electrically coupled in series between a power source and the controllable light source, but may not comprise a bidirectional semiconductor switch for controlling the amount of power delivered to the electrical load device using a phase-control dimming technique. The remote control device may have a low-profile enclosure that is smaller than an enclosure of a standard dimmer switch, and thus may be easier to install in an electrical wallbox. The remote control device may comprise two parts including an air-gap switch device and a wireless communication device mounted to the air-gap switch device.

  • Publication number: 20180287385
    Abstract: A load control system for a building having a lighting load, a window, and a heating and cooling system comprises a lighting control device, a daylight control device, and a temperature control device operable to be controlled so as to decrease a total power consumption of the load control system in an energy-savings mode. The energy-savings mode can be manually overridden in response to actuation of the actuator of an input control device, such that the load control system enters a manual mode for manually adjusting the loads controlled by the lighting control device, the daylight control device, and the temperature control device. The load control system is operable to automatically return to the energy-savings mode at a time after the load control system entered the manual mode.

  • Patent number: 9890587
    Abstract: A motorized roller tube for reeling and unreeling a flexible member between fully open and fully closed conditions operates with minimized sound level. A variable controller energizes a motor with a controllable RPM driving a gear reduction assembly. The motor has a speed versus torque characteristic which extends linearly from a high maximum RPM and low minimum torque, to a low minimum RPM and high maximum torque, and having a peak efficiency at a given RPM. The motor moves the flexible member between its fully open and fully closed positions at a motor speed less than the given peak efficiency RPM and less than 50% of its high maximum RPM, and at a motor efficiency which is less than 25% of the peak efficiency whereby the motor is intentionally operated in a high torque and low efficiency manner.

  • Publication number: 20170179762
    Abstract: A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of independent units responsive to a broadcast controller. Each independent unit includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a control signal received from the commander. The independent units are configured and operate independent of each other. The broadcast controller transmits wireless signals to the energy controllers of the independent units. The energy controllers do not respond to control signals received from the commanders of other independent units, but the energy controllers of both independent units respond to the wireless signals transmitted by broadcast controller. The energy controller may operate in different operating modes in response to the wireless signals transmitted by the broadcast controller.
