Abstract: Energy efficient transmissive and transreflective display devices are described. Ambient light from a natural or artificial source is used to replace and/or supplement light normally supplied by a backlight. This is done by directing ambient light to the rear of a transmissive display panel. A window, light tunnel, or a reflective surface located in the rear or top of a display device may be used to direct the ambient light to the back of the display panel. A translucent diffuser and/or diffuse reflector are used to diffuse the ambient light to reduce the chance of bright spots appearing on the display. Additional energy efficiency is achieved by using one or more photo-sensors to detect the amount of light, incident on the front and/or rear of a display panel and by automatically adjusting the backlight intensity as a function of photo-sensor output. In this manner, backlight intensity can be minimized while maintaining the viewability of images shown on the display. In such an embodiment, energy savings are achieved as compared to devices which use fixed backlight intensity settings in a variety of light conditions. Control of the power supplied to a display's backlight in accordance with the present invention can reduce electrical energy consumption and prolong the amount of time a portable device can be used before its batteries need to be recharged.

Abstract: A scrolling device for a computer may include a touch-sensitive surface, which may be elongated and/or have one or more active regions. Scrolling may be performed in manual as well as automated ways that may result in more accurate and efficient scrolling. Scrolling, as displayed on the screen, may further be rounded to the nearest document text line and/or distance unit, even though a more precise scrolling location value may be stored and/or tracked.

Abstract: A MEMS optical display system includes an illumination source for providing illumination light, a collimating lens for receiving the illumination light and forming from it collimated illumination light, and a converging microlens array having an array of lenslets that converge the collimated illumination light. The converging microlens array directs the illumination light to a microelectrical mechanical system (MEMS) optical modulator. The MEMS optical modulator includes, for example, a planar substrate through which multiple pixel apertures extend and multiple MEMS actuators that support and selectively position MEMS shutters over the apertures. A MEMS actuator and MEMS shutter, together with a corresponding aperture, correspond to pixel. The light from the converging microlens array is focused through the apertures and is selectively modulated according to the positioning of the MEMS shutters by the MEMS actuators, thereby to impart image information on the illumination light. The light is then passed to a diffused transmissive display screen by a projection microlens array.

Abstract: An improved method and system for reducing the power consumption of computing devices capable of communicating over a wireless network allows longer device operation and/or the use of smaller batteries. The wireless computing device supports a low power channel for receiving control signals during idle periods of operation. When the computing device is idle, the device is configured to power down all of its components with the exception of the circuitry required to power the low power channel. As such, the channel is maintained in an active state for receiving signals during both idle and non-idle periods, or in an embodiment, only during idle periods. When another device wishes to communicate with the wireless computing device, the low power channel passes a nullwake-upnull signal to the device indicating that the device be powered up from the idle mode of operation. A host RF component that is coupled to the network via a host computer generates this wake-up signal in an embodiment of the invention.

Abstract: An electrostatic bimorph actuator includes a cantilevered flexible bimorph arm that is secured and insulated at one end to a planar substrate. In an electrostatically activated state the bimorph arm is generally parallel to the planar substrate. In a relaxed state, residual stress in the bimorph arm causes its free end to extend out-of-plane from the planar substrate. The actuator includes a substrate electrode that is secured to and insulated from the substrate and positioned under and in alignment with the bimorph arm. An electrical potential difference applied between the bimorph arm and the substrate electrode imparts electrostatic attraction between the bimorph arm and the substrate electrode to activate the actuator. As an exemplary application in which such actuators could be used, a microelectrical mechanical optical display system is described.
