摘要： A control circuit having a drive circuit and a controller adapted for use in optical mice is disclosed. The drive circuit is connected between first and second ports and passes a current between those ports having an amplitude determined by a control signal that is generated by the controller. The first port is connected to an illumination device and the second port is connected to a power rail. The control circuit also includes a potential measuring circuit that generates a signal indicative of a drive circuit potential between the first and second ports. The controller records the drive circuit potential for a predetermined current when the first port is connected to an illumination device. The controller sets the control signal based on the recorded drive circuit potential. The control circuit can record the drive circuit potential when the controller is powered.

摘要： A pointing device and method for using the same are disclosed. The pointing device includes an illumination system, an imaging system, and a controller. The illumination system illuminates a portion of a surface over which the pointing device travels with coherent light. The imaging system includes a first window for receiving light from the illuminated portion of the surface and transmitting that light to a first imaging array such that a speckle pattern is generated on the first imaging array and a second window includes an imaging optical system for forming an image of part of the illuminated portion of the surface on a second imaging array. The controller selects either the first imaging array or the second imaging array and compares the output of the selected imaging array at first and second times to determine a displacement indicative of the direction and distance the pointing device moved.

摘要： An Electrical Fast Transient/Burst (EFT/B) detection and recovery system for a Universal Serial Bus (USB) device. The system includes a USB core and a burst controller. The USB core provides serial communications with a host device through a USB data channel. The burst controller is coupled to the USB core. The burst controller detects an EFT/B event and automatically reconnects the USB core to the host device in response to recognition of a suspend state of the USB core by the host device.

摘要： An optical navigation device includes a housing, a light source, a navigation sensor, and optics. In accordance with the invention, the light source is a vertical cavity surface emitting laser (VCSEL) that is configured to generate coherent light in the visible light spectrum. For example, the VCSEL generates red coherent light in the range of 600-700 nm. In an embodiment, the VCSEL generates red coherent light at 665 nm±20 nm. Because the light generated by the VCSEL is in the visible light spectrum, a human will sense contact with the corresponding beam and will naturally react to avoid injury. This enhances the overall safety of an optical mouse. Additionally, when using a VCSEL that generates visible red light, it is easy to visually determine whether or not the beam is focused directly on a measurement sensor during calibration.

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： A pointing device, such as an optical mouse, includes a light unit for illuminating a surface, a photodetector array configured to generate image information related to the illuminated surface, a navigation engine for generating navigation information at a target resolution of the pointing device, and a resolution input interface for controlling or adjusting the target resolution value of the pointing device via input of a resolution scaling ratio. The resolution input interface is configured for user input of the resolution scaling ratio, such that the target resolution of the pointing device can be readily adjusted, in real time, over a broad range of resolution values and in small increments. A technique for mitigating cursor jitter problems at high resolution values is also disclosed.
