    摘要: A flexible panel is provided that is easily and conformingly applied to a curved display screen of a VDU to afford, in a lightweight manner, variably adjustable contrast enhancement of the VDU while simultaneously providing a decrease in the amount of ambient light reflected from the curved display screen. The flexible panel is a glass microsheet layered, on one side thereof, with an antireflection coating and, on the other side, with an electrochromic device. The electrochrmic device allows for variable adjustment of the contrast of the VDU as a function of the voltage applied across the electrochromic device. The flexible glass microsheet dually possesses the advantages of conventional rigid glass panels, such as excellent optical performance, high durability, capability of being coated with various optical coatings under extreme temperature, pressure and chemical conditions and the additional benfeit of physical flexibility. This flexibility allows for easy application to variously sized and shaped curved VDU display screens. The electrochromic device is a six-layered structure deposited, in order from the layer adjacent the panel: a 1 quarter wavelength (QW) alumina layer; a first indium-tin-oxide (ITO) layer; a tungsten trioxide (WO.sub.3) layer; a tantalum pentoxide (Ta.sub.2 O.sub.5) layer; a nickel-oxide (NiO) layer; and a second indium-tin-oxide (ITO) layer.

    摘要: A switching signal having multiple sequential pulses is applied to a MEMS switch. A first pulse moves the switch from a first switch position toward a second switch position. After a selected dwell period, a second pulse is applied to dampen ringing or overshoot of the movable portions of the switch. In a further embodiment, non-symmetrical switching signals are used to cycle the switch from the first state to the second state, and back to the first.

    摘要: A elemental mirror for vehicles having a luminous reflectance of at least about 30% includes a substrate coated with a thin layer of elemental semiconductor having an index of refraction of at least 3 and an optical thickness of at least about 275 angstroms. Preferably, the elemental semiconductor coating is sputter coated silicon or germanium and a light absorbing coating is included therebehind. The mirror is spectrally nonselective with elemental semiconductor optical thicknesses of about 275 to 2400 angstroms on the front substrate surface. Spectrally selective mirrors are provided by adding an interference coating to the elemental semiconductor layer coating, preferably of a dielectric such as silicon dioxide or silicon nitride, on either the front or rear substrate surface, or by using a thicker, single elemental semiconductor layer. Instead of an absorbing coating behind the mirror, additional elemental semiconductor and dielectric thin layers may be included to reduce secondary reflections. The method includes coating the thin elemental semiconductor layer on flat glass and heating to harden the layer and make it more scratch resistant, or heating and bending the glass without destroying the reflective properties of the mirror. The thin interference layer, secondary reflection reducing layers, and/or light absorbing coating may be coated before or after heating and bending.

    摘要: A bi-stable micro-machined electromechanical system (“MEMS”) switch. In a preferred embodiment, the bi-stable MEMS switch is used in an N×N optical signal switching system. Spring arms act in conjunction with a hollow beam portion of a movable center body of the switch to accommodate strain in the arms as the switch is moved from a first position to a second position, thus avoiding buckling of the spring arms. Both the first and second switch position occur at local minimums of mechanical potential energy, thus providing two stable switch states. The center body is moved in relation to static portions of the switch by an actuator, such as an electro-static comb drive.
