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.

Lithographic mask correction using volume correction techniques

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.

Wireless solid state lighting controller

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 &#x201c;smart&#x201d; 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.

A PWM dimmer includes a source terminal, a load terminal, a power stage, an interface, and control circuitry. The power stage is coupled between the source terminal and the load terminal and is configured to receive from the source terminal an AC supply signal and provide a pulsed AC load signal to the load terminal in response to a control signal. The AC supply signal has a sinusoidal envelope with a positive half-cycle and a negative half-cycle for each cycle. The pulsed AC load signal tracks the envelope and includes a plurality of pulses in the positive half-cycle and the negative half-cycle for each cycle. The interface is configured to receive dimming control information bearing on a dimming level from a user or remote terminal. The control circuitry is configured to receive the dimming control information from the interface and generate the control signal based on the dimming control information.

A power supply includes a power conversion circuit configured to selectively operate in one of an active mode in which output power is supplied to a load and a standby mode in which output power is not supplied to the load, a plurality of auxiliary circuits including a first auxiliary circuit and a second auxiliary circuit, a bias node configured to supply power to the plurality of auxiliary circuits, and a switch that is coupled between the bias node and the first auxiliary circuit and that is configured to disconnect the first auxiliary circuit from the bias node in response to a control signal.
