摘要： An optical navigation system having an illuminator housing and a sensor housing that are movably connected at a connection point with a connection mechanism, which may include a pivot. The illuminator housing and the sensor housing may be rotated about the connection point relative to each other so that the optical navigation system may be configured with a desired operating Z-height. The optical navigation system may also include a locking mechanism to lock the illuminator housing and the sensor housing in a predetermined fixed position after the desired operating Z-height has been selected.

摘要： In one embodiment, apparatus for providing a visual indication of a position of a steerable wheel includes an encoder and a display system. The encoder has a mechanism for mounting part of the encoder to a movable component of a steering system coupled to the steerable wheel. The encoder produces an output signal related to a position of the movable component. The display system is responsive to the output signal produced by the encoder and displays the visual indication of the position of the steerable wheel. Other embodiments are also disclosed.

摘要： An optical navigation system having two or more optical pipelines for image acquisition and a single multiplexed optical array. Each of the two or more optical pipelines for image acquisition may include an illuminator that emits optical radiation at a navigation surface where each navigation surface is separate from the other navigation surfaces. The single multiplexed optical array may be configured to receive optical radiation reflected from the respective navigation surfaces. The optical navigation system may further include illuminator drivers that control each of the optical pipelines for image acquisition and an optical sensor that is configured to multiplex the images recovered by the optical pipelines for image acquisition and perform image correlation for the different navigation surfaces.
