Abstract: A configurable wall mount light switch for use in controlling multiple light fixtures. In one embodiment, the switch includes a touch screen display, a transceiver and a programmable microcontroller. The microcontroller may be programmed to display a plurality of interface elements on the touch screen display for selection by a user to control one or more light fixtures. Typically, the switch is dimensioned to be received by a single gang electrical box.

Abstract: A lighting control system for controlling lights of buildings includes a computer server communicating with programmable master interfaces through an Ethernet communication link. The server is programmed to establish control commands responsive to environment status information. The master interfaces communicate through a primary communication link with programmable input devices which include input interfaces and smart switches, and with programmable output devices. The output devices communicate with a master interface through its primary communication link and also communicate with programmable relay/dimmer devices through a secondary communication link. The relay/dimmer devices control building lights responsive to control commands. The input interfaces communicate with a master interface through its primary communication link and also communicate with ambient light/occupancy sensor devices through a secondary communication link.

Abstract: A computerized method for controlling one or more a lights in an area. The method may include establishing an electronic profile of lighting conditions in an area to be controlled and then controlling lighting conditions in the area based on the profile. For example, the profile could be created by determining a respective influence on artificial light of each switch within the area to be controlled. This information could be used to turn on the appropriate switches that best match a set point for a light level in the area.

Abstract: A method of determining the position of a probe tip. An evanescent electromagnetic field is generated extending beyond an interface boundary between a first medium, having a first refractive index, and a second medium, having a second refractive index which is greater than the first refractive index, the interface boundary extending in a plane. A probe tip is positioned in the evanescent field in the first medium thereby causing propagating electromagnetic radiation to be produced as a result of the disruption of the evanescent field by the probe tip, and at least a portion of the propagating electromagnetic radiation is collected. The spatial intensity distribution of the collected radiation is detected with respect to an image plane. An at least one dimensional position of the probe tip in a probe tip plane is determined from the detected spatial intensity distribution, the probe tip plane being a plane which contains the probe tip and which is substantially parallel to the plane of the interface boundary.
