Abstract: An apparatus for providing a private multiple screen includes a signal modification element and a communication element. The signal modification element is configured to apply a privacy operation to an input video signal to produce a modified video signal. The communication element is in communication with the signal modification element and is configured to transmit security information to the receiving device to enable the receiving device to substantially restore the input video signal.

Abstract: The specification and drawings present a new method, apparatus and software product for dynamically adjusting a color gamut of a display (e.g., a field sequential color display) and further adjusting a luminance of the display in an electronic device by adjusting and turning on field duties of primary colors. During each color field, the other primary colors of light sources supporting the display can be turned on at their respective fractions of their color field. These fractions can be continuously tunable in order to control the color coordinate of each primary color dynamically thus adjusting the color gamut and the luminance of the display.

Abstract: A combined input/output device having a display mode in which it operates as a matrix display and sensing mode in which it receives optical input, comprising multiple picture element circuits arranged as a matrix display and multiple optical sensors arranged as a sensor matrix. The optical sensors and pixel circuits are integrated on the same substrate and the control lines used for controlling the pixel circuits are advantageously re-used for controlling the optical sensors. A plurality of optical sensors are enabled at a time, thereby allowing for the discrimination of inputs by gesture.

Abstract: A screen basket for screening suspensions, containing wearing particles, comprises a circumferential wall of a base material provided with screen passages, and a wear resistant outer layer of a material, typically chromium, which is harder than the base material and covers the circumferential wall. At least one wear-indicating layer is applied on the circumferential wall between the latter and the outer layer and adapted to indicate when at least a portion of the outer layer has been worn down to the wear-indicating layer.

Abstract: A display device comprising: display element switchable to adjust the transmission of light therethrough; and a reflector located behind the display element for receiving ambient light transmitted through the display element and reflecting it back through the display element; wherein the diffusivity of the reflector is adjustable.

Abstract: A light modulating apparatus includes a semiconductor device having a quantum well structure and a device for applying an electric field to the quantum well structure of the semiconductor device. Both of pump and probe light beams or a pump and probe light beam is input into the semiconductor device. The pump light beam or pump and probe light beam received by the semiconductor device causes a real charge excitation in the quantum well structure, and the real charge excitation screens the electric field applied to the quantum well structure. The polarization state of the probe light beam or pump and probe light beam emerging from the semiconductor device is changed by an electrooptical effect in the quantum well structure induced by the real charge excitation. A polarizer may be disposed for converting a change in polarization state of the light emerging from the semiconductor device into a change in intensity of the light.
