Abstract: A capacitive power transfer system can include a power transmitter having one or more primary side filter components, a communications modulator, and transmitter capacitive couplers; and a power receiver having receiver capacitive couplers capacitively coupled to the transmitter capacitive couplers, one or more secondary side filter components, and a communication demodulator. The one or more primary side filter components and the one or more secondary side filter components can be selected to provide power amplifier operation at a power delivery frequency and act as a stable gain high pass filter above a communications cutoff frequency that is higher than the power delivery frequency.

Abstract: A liquid crystal display may have a layer of liquid crystal material. The display may have an array of display pixel circuits. The display pixel circuits may each include a display pixel electrode that applies electric fields to a corresponding portion of the liquid crystal material. Thin-film transistor circuitry and other structures in the display pixels may control operation of the display pixels circuits. The thin-film transistor circuitry may be configured to handle operation of the display at multiple refresh rates. To accommodate multiple refresh rates, each pixel circuit may include a pair of transistors. A first transistor is used to apply data signals from a data line to the display pixel electrode. A storage capacitor is used to maintain the data signal on the electrode. The second transistor may be used to adjust the capacitance of the storage capacitor depending on the refresh rate of the display.

Abstract: An optical system may include equipment with a housing that is configured to receive external equipment such as a cellular telephone. The external equipment may have a display mounted on a front face of the external equipment and may have additional components such as a front-facing camera. Communications circuitry in the equipment may support wired and wireless communications with the external equipment. An optical combiner in the equipment may be used to combine display image light emitted from pixels in the display with real-world image light received from external objects. The optical combiner may have a reflector with a concave lens shape that focuses light from the display towards eye boxes in which a viewer's eyes are located. The reflector may be a partial mirror or a reflective polarizer. The reflective polarizer and additional components may be used in implementing a tunable tint layer.
