Abstract: Lighting control systems may be commissioned for programming and/or control with the aid of a mobile device. Design software may be used to create a floor plan of how the lighting control system may be designed. The design software may generate floor plan identifiers for each lighting fixture, or group of lighting fixtures. During commissioning of the lighting control system, the mobile device may be used to help identify the lighting devices that have been installed in the physical space.

The unique identifier may be communicated by visible light communication (VLC) or RF communication. The unique identifier may be associated with the floor plan identifier for communication of digital messages to lighting fixtures installed in the locations indicated in the floor plan identifier.

Abstract: The lighting device may be configured to perform black body curve fading. For example, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting load is adjusted (e.g., faded) along a black body curve. The control circuit may be configured to determine whether to fade from an initial color to a destination color in a Correlated Color Temperature (CCT) chromaticity space or an XY chromaticity space. The control circuit may be configured to determine whether the initial color and/or the destination color are on the black body curve. When the initial color and the destination color are determined to be on the black body curve, the control circuit may be configured to control the drive circuit such that the light emitted by the lighting device is adjusted from the initial color to the destination color along the black body curve.

Abstract: In one embodiment, an RF impedance matching circuit is disclosed. The matching circuit is coupled between a plasma chamber and an RF source. The matching circuit includes a first electronically variable capacitor (EVC) having a first variable capacitance, a terminal of the first EVC being operably coupled to the RF input, and a second EVC having a second variable capacitance, a terminal of the second EVC being operably coupled to the RF output. A control circuit determines, based on a first parameter, a first capacitance value for the first EVC and a second capacitance value for the second EVC. The control circuit then generates a control signal to alter the first and second variable capacitances accordingly. The alteration of the capacitances, while the frequency of the RF source is not altered, causes RF power reflected back to the RF source to decrease.

Abstract: A method and apparatus for spatially switching radio frequency (RF) power from a single RF power generator to a selected one of two or more impedance matching networks coupled to associated RF electrodes for forming plasma in a plasma chamber. Full RF power may be switched within microseconds to the selected one of the two or more impedance matching networks. The two or more impedance matching networks may be coupled to one or more plasma generating electrodes. The two or more impedance matching networks may be interleaved during plasma processing recipe operation. Impedance matching networks can alternate back and forth during operation of a plasma processing recipe. This interleaving in operation and impedance transformation capabilities may also be performed with more than two impedance matching networks, and may be beneficial in enabling the use of fixed tuned impedance matching networks instead of requiring variable impedance matching networks having variable tuning capabilities.
