Abstract:
The present invention combines a conventional audio microphone with an additional speech sensor that provides a speech sensor signal based on an input. The speech sensor signal is generated based on an action undertaken by a speaker during speech, such as facial movement, bone vibration, throat vibration, throat impedance changes, etc. A speech detector component receives an input from the speech sensor and outputs a speech detection signal indicative of whether a user is speaking. The speech detector generates the speech detection signal based on the microphone signal and the speech sensor signal.

A pad for a computer input device includes a top surface over which the input device is slid and a bottom surface, opposite the top surface, for contacting a support surface. The bottom surface having a raised pivot portion allowing movement of the pad about the pivot portion.
Abstract:
A device for detecting the position of a human finger or other object on a touch-sensitive scrolling pad. Dual independent oscillators may be used to generate two pulse trains at frequencies dependent upon the capacitance of two conductors resulting from the position of the finger on the conductors. The pulses from each oscillator may be counted over a time interval. A ratio-metric measurement may be taken by calculating the ratio of the two counts, and a sum may also be calculated. The ratio of the two counts relates to finger position on the device, and their sum relates to finger pressure upon the device.

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 out-of-plane thermal buckle-beam microelectrical mechanical actuator is formed on a planar substrate of semiconductor material (e.g., silicon). The actuator includes first and second anchors secured to the substrate and multiple elongated thermal buckle beams that are secured between the anchors. The buckle beams are formed of semiconductor material, such as polysilicon. In one implementation, the buckling beams are coupled together by a pivot frame that includes a frame base secured to each buckle beam and at least one pivot arm that is coupled to the frame base at one end and includes a free end that pivots out-of-plane when the actuator is activated. A cyclic current source directs cyclic electrical current through the thermal buckle beams via the anchors to impart thermal expansion of the buckle beams and hence a cyclic buckling motion of them out of the plane (i.e., away from) the substrate. In one implementation, the actuator has a characteristic resonant deflection frequency range and the cyclic current is of a first frequency within the resonant deflection frequency range.

An electret accelerometer is provided in which a diaphragm, an electret, a back plate and an electronic circuit are placed in a casing and the casing is sealed to isolate the diaphragm from external acoustic signals.
Abstract:
In an example embodiment, a method is adapted to tracking input with a device. The method includes an act of monitoring and acts of activating and displaying if a touch input is detected. The device has a first side and a second side, with the second side opposite the first side. The device has a display screen disposed on the first side, and a screen-reflective interface disposed on the second side. Respective positions on the screen-reflective interface correspond to respective locations of the display screen. The screen-reflective interface of the device is monitored. If a touch input is detected on the screen-reflective interface, the device performs acts of activating and displaying. Specifically, a tracking state is activated for the screen-reflective interface responsive to the detected touch input on the screen-reflective interface. The interface icon is displayed on the display screen to indicate that the tracking state has been activated.
Abstract:
A system that facilitates managing resources (e.g., functionality, services) based at least in part upon an established context. More particularly, a context determination component can be employed to establish a context by processing sensor inputs or learning/inferring a user action/preference. Once the context is established via context determination component, a power/mode management component can be employed to activate and/or mask resources in accordance with the established context. The power and mode management of the device can extend life of a power source (e.g., battery) and mask functionality in accordance with a user and/or device state.
Abstract:
Virtual controllers for visual displays are described. In one implementation, a camera captures an image of hands against a background. The image is segmented into hand areas and background areas. Various hand and finger gestures isolate parts of the background into independent areas, which are then assigned control parameters for manipulating the visual display. Multiple control parameters can be associated with attributes of multiple independent areas formed by two hands, for advanced control including simultaneous functions of clicking, selecting, executing, horizontal movement, vertical movement, scrolling, dragging, rotational movement, zooming, maximizing, minimizing, executing file functions, and executing menu choices.
