Abstract: A wireless light socket assembly for remotely actuating a light bulb includes a socket unit that has a male connector that is threadable into an existing light socket in a building. The socket unit has a female coupler integrated into the socket for insertably receiving a light bulb and the female coupler is in communication with the male connector. A communication unit is integrated into the socket unit and the communication unit is in remote communication with a security system of the building. The communication unit actuates the female coupler when the communication unit receives an alert signal from the security system to visually alert an observer that the security system has been triggered.

Abstract: A touch panel device including, and arranged above each other in a downward direction, a cover layer, a sensor layer including a plurality of sensing elements, characterized in that between the cover layer and the sensor layer is an electrically-resistive layer, electrically resistive layer being an electrically non-insulating layer and having an electrical resistance is provided, wherein the electrical resistance of the electrically-resistive layer is lower than the electrical resistance of the cover layer and higher than the electrical resistance of the sensing elements.

Abstract: The invention provides a touch panel device comprising, and arranged above each other in a downward direction, a cover layer for use as a touch surface, a sensor layer comprising a plurality of sensing elements, the sensing elements being arranged to register capacitance, characterized in that between the cover layer and the sensor layer is an electrically-resistive layer, electrically resistive layer being a electrically non-insulating layer and having an electrical resistance is provided, wherein the electrical resistance of the electrically-resistive layer is lower than the electrical resistance of the cover layer and higher than the electrical resistance of the sensing elements. The electrically-resistive layer can have a resistance suitable for causing, in response to a touch event above a center of a central sensing element, a detectable change in the capacitance as measured by at least two sensing elements adjacent to the central sensing element.

Abstract: A liquid crystal display is provided to include a display panel with a plurality of pixels, which are arranged in rows and columns in a matrix form. Each pixel has a plurality of sub-pixels of first, second, third and fourth sub-pixel types, respectively, corresponding to red, green, blue and white (RGBW) colors and interleaved together. Each succession of first, second, and third sub-pixels form a first sub-pixel group, and a subsequent fourth sub-pixel forms a second sub-pixel group. The sub-pixels are arranged such that the second type of the sub-pixels and the fourth type of the sub-pixels are in a same column. In each row, the sub-pixel in a rightmost column is of the same sub-pixel type as the sub-pixel in a leftmost column of that row.

Abstract: A tunable tandem Fabry-Perot etalon in used in wavelength division multiplexed optical systems or in an optical device. One path is used to calibrate the pre-spectral range with respect to a reference wavelength and the other path is used to select and acquire the desired wavelength.
