摘要： A device includes a light emitter, a current sensing resistance, a current generator, and detection circuitry. The current generator is connected to the light emitter and to the current sensing resistance. During a normal operating mode of the device, the current generator regulates current flow through the light emitter. In a test mode, the current generator regulates current flow through the current sensing resistance. The detection circuitry, during the test mode, detects when current flow through the current sensing resistance is outside an expected range.

摘要： An apparatus for controlling the position of a screen pointer includes an at least partially coherent light source for illuminating an imaging surface, thereby generating reflected images. The apparatus includes a navigation sensor for generating digital images based on the reflected images, performing a movement computation based on the digital images, generating movement data based on the movement computation that is indicative of relative motion between the imaging surface and the apparatus, wherein the movement computation has a low sensitivity to effects in the digital images caused by particle contamination.

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.

摘要： An integrated circuit package includes an angled one-piece substrate having a light source fixed to one area and a sensor die fixed to a second area, such that the light source is directed to illuminate the field of view of the sensor die when a surface of interest is imaged. The integrated circuit package is well suited for generating navigation information regarding movement relative to a surface. In one method of forming the integrated circuit package, the single-piece substrate is originally a generally flat lead frame to which the sensor die and light source are attached. After the components have been connected, the lead frame is bent to provide the desired light source-to-sensor angle. In an alternative method, the lead frame is pre-bent. For either method, optics may be connected to the integrated circuit package, thereby providing a module that includes the optics, the light source, the sensor and the packaging body.
