Abstract: The present invention includes a pointing device having a first surface on which a puck field of motion is defined, a moveable puck, and a position detector. The moveable puck is confined to move on the first surface within the puck field of motion. The position detector periodically determines a position of the puck in the puck field of motion and an angle of rotation of the puck about an axis perpendicular to the first surface. In one embodiment, the puck includes a puck electrode on a second surface on the puck that is parallel to the first surface. The first surface includes first, second, and third electrodes that are parallel to the puck electrode, the puck electrode overlying a portion of each of the first, second, and third electrodes.

Abstract: 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.
