A coincident fastener for use with a display unit of a configurable imaging system, comprising a screw for insertion through the display unit, wherein the screw includes a head portion, a threaded male portion at an end of the screw opposite the head portion, and an anti-rotation locking mechanism for locking the screw relative to the display unit.

Coincident fasteners for configurable imaging systems

For use in an imaging system having a plurality of adjacent display units, the improvement comprising a thermal actuator in at least one of the display units for moving a screen thereof away from a chassis thereof when the said display unit exceeds a predetermined temperature, so as to prevent mechanical interference between the adjacent display units.

Thermal actuator for configurable imaging systems

An expanding chassis for an imaging unit is provided, the expanding chassis for use in imaging systems having a plurality of imaging units arranged in an array. The expanding chassis comprises a rigid frame for housing a light engine and related circuitry, and for mounting a screen on a front surface of the rigid frame for use with the light engine. The expanding chassis further comprises at least one expandable interface pad on at least one side of the rigid frame. The rigid frame and the expandable interface pad have a combined thermal expansion characteristic that provides an overall expansion in the expanding chassis that substantially matches the expansion of the screen.
