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： 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： 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.

摘要： A device for detecting the presence of an object is provided. The device includes a light source, a current controller coupled to the light source, a sensor and a pattern detection engine. The current controller sets to provide the light source with a drive current having a pattern. The sensor is operable to receive light, notably light reflected from an object at the detection area and subsequently generates a signal in response to the light received. The pattern detection engine receives the signal from the sensor and subsequently reports the presence of the object upon determining the presence of the pattern in the signal. The object detection system is further configured to provide a navigation operation when an object is detected at the detection area.

摘要： In one aspect, a diagnostic test system includes a housing, a reader, and a data analyzer. The housing includes a port for receiving a test strip. The reader obtains separable light intensity measurements from localized regions of an area of the detection zone exposed for optical inspection, wherein each of the localized regions is characterized by at least one surface dimension smaller than the first dimension. The data analyzer identifies ones of the light intensity measurements obtained from the at least one test region and computes at least one parameter from the identified ones of the light intensity measurements. In another aspect, the reader obtains a respective set of light intensity measurements from each of multiple corresponding regions of the exposed surface area of the detection zone, and the data analyzer computes at least one parameter from at least one of the sets of light intensity measurements.
