摘要： An apparatus and method for integrating an optical navigation mechanism with non-optical sensor are described. At least one optical sensor is provided that detects light and converts the detected light into a corresponding electric signal. An optical navigation mechanism that employs the output of the optical sensor to provide user-controllable cursor navigation is also included. The optical navigation mechanism has a power saving state and an operation state. A non-optical sensor is provided that detects the presence or absence of an object in the vicinity of the non-optical sensor and selectively generates a present signal. A power saving mechanism is coupled to the non-optical sensor and receives the present signal and responsive thereto causes the optical navigation mechanism to transition from the power saving state to the operation state or from the operation state to a power saving state.

摘要： An optical navigation system. The optical navigation system includes an image sensor capable of optical coupling to a surface of an object, a data storage device, and a navigation circuit. The image sensor includes multiple photosensitive elements with the number of photosensitive elements disposed in a first direction greater than the number of photosensitive elements disposed in a second direction. The second direction is perpendicular to the first direction. The image sensor is capable of capturing successive images of areas of the surface, the areas located along an axis parallel to the first direction. The data storage device is capable of storing the captured images. The navigation circuit includes a first digital circuit for determining an estimate for the relative displacement between the image sensor and the object along the axis obtained by comparing the image captured subsequent to the displacement to the image captured previous to the displacement.

摘要： A contaminant-neutralizing cradle comprises a base and a support surface configured to removably receive a coherently-illuminated mouse. A neutralizing element is disposed on the support surface for alignment with at least one exposed surface of an optics module of the mouse and is configured to neutralize the optical effect of a contaminant on the at least one exposed surface. A method of neutralizing contaminants for an optical mouse comprises providing a mouse containing an optics module having at least one surface exposed to an opening of the mouse and interposing a barrier in the mouse between a contaminant and the at least one exposed surface. A method of detecting contaminants comprises aligning an optics module of a mouse with an imaging surface, obtaining a first image of the imaging surface, via application of coherent illumination from the optics module to the imaging surface, analyzing the first image to identify an interference pattern associated with a contaminant, alerting a user if a parameter of the interference pattern exceeds a threshold value.
