    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.

    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 "wake-up" 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: A method and system use an alternative sensor signal received from a sensor other than an air conduction microphone to estimate a clean speech value. The estimation uses either the alternative sensor signal alone, or in conjunction with the air conduction microphone signal. The clean speech value is estimated without using a model trained from noisy training data collected from an air conduction microphone. Under one embodiment, correction vectors are added to a vector formed from the alternative sensor signal in order to form a filter, which is applied to the air conductive microphone signal to produce the clean speech estimate. In other embodiments, the pitch of a speech signal is determined from the alternative sensor signal and is used to decompose an air conduction microphone signal. The decomposed signal is then used to determine a clean signal estimate.

    Abstract: A mobile device is provided that includes a digit input that can be manipulated by a user's fingers or thumb, an air conduction microphone (108) and an alternative sensor (112,114) that provides an alternative sensor signal indicative of speech. Under some embodiments, the mobile device also includes a proximity sensor (116) that provides a proximity signal indicative of the distance from the mobile device to an object. Under some embodiments, the signal from the air conduction microphone, the alternative sensor signal, and the proximity signal are used to form an estimate of a clean speech value. In further embodiments, a sound is produced through a speaker (110) in the mobile device based on the amount of noise in the clean speech value. In other embodiments, the sound produced through the speaker is based on the proximity sensor signal.

    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 microlens array having an array of lenslets and receiving the illumination light from the collimating lens. The converging microlens array directs the illumination light to an array of pixel apertures in an aperture plate and then to a microelectrical mechanical reflector array positioned opposite the aperture plate. The microelectrical mechanical reflector array includes an array of microelectrical mechanical actuators that support reflectors in alignment with the array of pixel apertures. The array of microelectrical mechanical actuators orients the reflectors selectively to direct the illumination light back through the pixel apertures or against the aperture plate. The illumination light passing back through the pixel apertures passes through the microlens array and a beamsplitter to a display screen.
