    Abstract: Systems and methods are provided that facilitate automatic convergence and geometry alignment in projection systems. Preferably, an optical element such as a lens array is coupled to all areas of the projection system's screen and to a detector element such as a photocell array. In operation, each lens of the lens array is adapted to map an individual portion or region of the screen onto the photocell array. A microprocessor, controller or the like uses the data output from the photocells to instruct an alignment controller to center or steer the beams to compensate for convergence error at a particular location. In a center alignment mode, four (4) or more beacon dots located about the periphery of the screen are detected to determine screen size and position, which is used to center the video image and the centers of the mapped regions on the screen.

    Abstract: An adjustable shim for aligning a component of a manufactured device comprising plates for mounting or abutting the shim to the component to be aligned and to a stationary portion of the device, an adjustable retainer wall extending between the plates and enclosing a volume filled with thermoplastic material having a melting temperature that exceeds the operating temperature of the component to be aligned. In operation, the component to be aligned is mounted to the shim and the shim is mounted to a stationary portion of the manufactured device and the device is then positioned on a tool defining a predetermined alignment of the component. The thermoplastic material is then heated to its melted state and the alignment of the component is adjusted to the predetermined alignment set by the tool while the thermoplastic material is in its melted state. The thermoplastic material is then cooled to fix the shim and component in the adjusted position.
