  • Publication number: 20070126368
    Abstract: A programmable wallbox dimmer is disclosed. Upon entering a programming mode, the dimmer presents a main menu from which the user may select one or more features to program. The user may scroll through a list of programmable features by actuating the dimmer's raise/lower intensity actuator. The user may select a highlighted feature by actuating the dimmer's control switch. The dimmer may enter a value selection mode that is associated with the selected feature. In the value selection mode, the user may scroll through a list of features that define the selected feature by actuating the dimmer's raise/lower intensity actuator. The user may select a value for the selected feature. The selected value may be stored in the dimmer's memory.

  • Patent number: 4727296
    Abstract: A plurality of groups of linearly adjustable control potentiometers control respective lights of a given light scene in a given area. A particular group of potentiometers to control the scene is selected by a respective push-button switch on the control panel. Each of the potentiometer control sliders has an LED which is illuminated when its group of potentiometers is selected. Each of the control potentiometers controls a respective dimmer control circuit. Respective fader circuits are connected to each dimmer control circuit. All fader circuits are adjusted by a single potentiometer having a logarithmic response function. The single adjustment potentiometer is mounted on the control panel. All of the dimmer control circuits are remotely located from the control panel. The control panel is covered by a solid cover or a translucent cover through which only illuminated LEDs on the potentiometer sliders are visible.
