Abstract:

A method of making a mask includes computing a mask volume correction matrix for a given mask layout to be used to perform a lithography process. The mask volume correction matrix represents a diffraction field for a predetermined thickness of a material of the mask. A simulated mask pattern is computed by applying the mask volume correction matrix to the given mask layout. The simulated mask pattern is provided to a mask making tool.

Abstract:

A lighting controller comprises power circuitry, transmitter circuitry, a touch-sensitive panel, and processing circuitry. The power circuitry is configured to relay power from the lighting controller to a solid state lighting fixture wired to the lighting controller. The transmitter circuitry is configured to wirelessly exchange signals with the solid state lighting fixture. The touch-sensitive panel is configured to emit light and receive touch input from a user. The processing circuitry is electrically coupled to the power circuitry, the transmitter circuitry, and the touch-sensitive panel. The processing circuitry is configured to wirelessly control, via the transmitter circuitry, the attribute of light emitted by the solid state lighting fixture in accordance with the touch input received via the touch-sensitive panel and control the light emitted from the touch-sensitive panel to indicate the attribute as the attribute is wirelessly controlled.

Abstract:

A lighting wall controller can be a retrofit for existing light switches, and the lighting wall control replaces the conventional light switch and can still work as a conventional light switch or other power switch with “dumb” lights or appliances while providing the ability to control “smart” lights and/or other “smart” devices with voice commands. In addition to controlling lights and/or devices, voice commands can be used to provide information or actions back to the user in response to the voice command. The lighting wall controller thereby provides voice control functionality without requiring additional devices, such as additional voice control appliances.
