摘要： Various systems and methods are employed for lift-detection. Beam triangulation can be used, and in one embodiment, an optical lift detection module is separate from the optical tracking module. In one embodiment, a capacitive lift detection technique is used. A capacitor is built into the bottom case of the mouse. When the mouse is resting on a surface, the surface material serves as a dielectric for the capacitor, while air serves as the dielectric when the mouse is lifted. This dielectric change leads to a change in the capacitance value, leading to detection of lift. In one embodiment, a capacitor with an easily compressable material inserted between the two electrodes is used. In another embodiment, a mechanical plunger with an elastic membrane is used for lift detection. Lift detection can be tunable and/or customizable. The actual height of the life can be detected, rather than simple on-off notifications.

摘要： Embodiments of the present invention include a roller for an input device, where the roller's absolute angular position is measured by a magnetic encoder. A magnet is attached to the roller, possibly inside the roller so as to make the embodiment more compact. In one embodiment, the magnetization is simple and low cost. Further, tight tolerances are not required, and such a system is easy to manufacture. In one embodiment, the sensor is covered by any non-ferromagnetic material, to protect it from foreign particles, and to reduce ESD. In one embodiment, the wheel consumes much less power than conventional wheels in input devices. In one embodiment, the tilting of the wheel is measured using the same sensor that is used for measuring the rotation of the wheel. In one embodiment, a ratcheting feel provided to the user when rotating the wheel is synchronized with the rotation signal.

摘要： Embodiments of the present invention enable an optical device to track on a diffusing surface over which a transparent and/or translucent and/or optically smooth surface is placed. Some embodiments are directed towards detecting when an optical device is lifted off the surface it was resting on. Embodiments also include a sensing system that detects the z distance (distance to the tracking surface) and improves image quality by improving the effectiveness of the optical sensor subsystem and/or the illumination subsystem at the detected z distance. Other embodiments include a system and method that enables an optical device to track on a transparent and/or translucent and/or optically smooth surface alone. This may involve dark-field imaging based on certain features (e.g., dirt) already present on the transparent surface. Alternately, this may involve creating features such as droplets, spreading dirt residue, and creating thermal spots, which can be used for tracking.

摘要翻译： 本发明的实施例使得光学装置能够在扩散表面上进行跟踪，在漫射表面上放置透明和/或半透明和/或光学平滑的表面。 一些实施例旨在检测何时将光学装置从其搁置的表面上提起。 实施例还包括检测z距离（到跟踪表面的距离）的感测系统，并且通过改善在所检测的z距离处的光学传感器子系统和/或照明子系统的有效性来提高图像质量。 其他实施例包括使光学装置能够单独在透明和/或半透明和/或光学平滑表面上追踪的系统和方法。 这可能涉及基于已经存在于透明表面上的某些特征（例如，污物）的暗场成像。 或者，这可能涉及产生诸如液滴，铺展污垢残留物以及产生可用于跟踪的热点的特征。

摘要： A system, method, and method of manufacturing directed to an optical device with increased accuracy in tracking ability. The increased accuracy can be achieved by using a multiple sensor system. A second sensor is added to the optical device. The second sensor increases the probability of obtaining a high quality image. Thus, the tracking ability of the device can be performed with greater accuracy over a single sensor device. The second sensor can also perform additional functions.
