摘要： A light modulator and a method of manufacturing the same are provided having a continuously deformable optical surface. Generally, the modulator includes a substrate, a membrane disposed above and spaced apart from an upper surface of the substrate, the membrane having a continuously deformable light reflective surface formed on its upper side facing away from the upper surface of the substrate, and a means for deflecting the deformable surface relative to the substrate. Light reflected from different points of the deformable surface can interfere to modulate light reflected from the modulator in 0th order applications. In one embodiment, the membrane includes a static reflective surface surrounding the deformable surface. Light reflected from the static surface and the deformable surface can interfere to modulate light reflected from the modulator in non-0th order applications. Preferably, the static surface is substantially planar and the deformable surface are sized and shaped to define substantially equal areas. In one embodiment, the static surface circumscribes the deformable surface to define a parabolic reflector.

摘要： A light modulator and a method of manufacturing the same are provided having a substrate with reflectivity enhancing layers formed thereon. The layers include at least a top surface for receiving incident light, a first layer overlying the substrate, and a second layer between the top surface and the first layer, the second layer overlying and abutting the first layer. The second layer has a predetermined thickness selected in relation to an index of refraction of the second layer and to a wavelength of the incident light such that the light reflecting off an interface between the first and second layers constructively interferes with light reflected from the top surface. Preferably, the first layer also has a predetermined thickness selected such that the light reflecting off an interface between the first layer and the substrate constructively interferes with light reflected from the top surface.

A system in accordance with one embodiment includes a motion-based input device adapted to move relative to a surface. The input device has one or more force sensors capable of detecting forces acting upon the input device. The system may then move a navigational object displayed on a receiving device in relatively small increments or relatively large increments, depending upon the detected forces acting upon the input device.

摘要： An input device includes a deflection based capacitive sensing input. Deflection of a metal fame of the input device causes a change in capacitance that is used to control a function of an electrical device. The input appears selectively visible because it is made of the same material as the housing it is contained in and because it is selectively backlit through tiny holes.

摘要： An electronic device may have a housing in which an antenna is mounted. An antenna window may be mounted in the housing to allow radio-frequency signals to be transmitted from the antenna and to allow the antenna to receive radio-frequency signals. Near-field radiation limits may be satisfied by reducing transmit power when an external object is detected in the vicinity of the dielectric antenna window and the antenna. A capacitive proximity sensor may be used in detecting external objects in the vicinity of the antenna. The proximity sensor may have conductive layers separated by a dielectric. A capacitance-to-digital converter may be coupled to the proximity sensor by inductors. The capacitive proximity sensor may be interposed between an antenna resonating element and the antenna window. The capacitive proximity sensor may serve as a parasitic antenna resonating element and may be coupled to the housing by a capacitor.
