Abstract: A projection screen for displaying projected images with a movable shutter that can be positioned and opened at any location within a large rectangular area of the surface of the projection screen. Physical objects and light signals may pass through the open shutter. When the shutter is closed, the projection screen appears to a viewer as a continuous, unbroken, vertical reflective surface.

Abstract: A method and system for identifying sets of instructions within a computer program, execution of which serve as an indicator for processing of a transaction by the computer program and that together comprise a witness set. The witness set may be employed to monitor execution of the computer program and detect processing of the transaction. Witness sets are constructed by iteratively filtering an initial set of instructions based on profile data collected during execution of the computer program.

Abstract: A lamination process for orienting and conforming a film or sheet material to a substrate surface having a surface feature such that the film or sheet material reflects the surface feature includes interposing an adhesive between the film or sheet material and the substrate surface and opposing the film or sheet material and the substrate surface; providing at least two manifolds, where each manifold provides a plurality of flow streams of a pressurized liquid, each flow stream being oriented to effectuate a clear but minimally overlapped resulting flow stream from each manifold; and directing the resulting flow streams onto the film or sheet material to coincide at a contact nip line with at a force effective to conform the film or sheet material to the surface feature of the substrate surface. The resulting flow streams are maintained for sufficient time to adhere the film or sheet material to the substrate.
