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： The present invention detects single faults that would cause the current flowing through the light source to increase by a significant amount over the intended value. When the fault is a small leakage path to Ground potential from the light source cathode, it can be detected while maintaining operation of the light source within eye safety limits. In addition, the fault may be detected without activating the light source.

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.

摘要： An apparatus such as a wireless telephone is disclosed, the apparatus having a screen with an icon, and an input device for controlling the icon on the screen. The input device includes a sensor adapted to detect movement and a captive disc movably suspended over the sensor, the captive disc having an active surface facing the sensor and the sensor viewing a portion of the active surface. When the captive disc is moved, the sensor detects differing portions of the active surface and determines movement by changes in its view. Because the captive disc is substantially flat, the input device can be relatively small in size compared to input devices of the current art. The smaller size requirement is advantageous for implementing the input device in various devices including the PDAS, wireless communication devices, and other electronic equipment.
