Abstract: Aspects of the present invention relate to systems, methods, and computer program products for measuring and compensating for optical distortion. The system includes a plurality of reference marks; a recording device configured to record a first orientation and a first position of a plurality of reference marks relative to a pointing angle of the recording device when an object is located outside of a field of view of a recording device, the recording device configured to record a second orientation and a second position of a plurality of reference marks relative to the pointing angle of the recording device when an object is located inside the field of view; and a processor configured to compare the first orientation and the first position of the plurality of reference marks to the second orientation and the second position of the plurality of the reference marks for measuring distortion of the object.

Abstract: A bus switching apparatus and method for multiple processor computer systems comprises a plurality of bus switches interconnected by branch buses. Each processor or other module of the system is connected to a spigot of a bus switch. Each bus switch also serves as part of a backplane of a modular crate hardware package. A processor initiates communication with another processor by identifying that other processor. The bus switch to which the initiating processor is connected identifies and secures, if possible, a path to that other processor, either directly or via one or more other bus switches which operate similarly. If a particular desired path through a given bus switch is not available to be used, an alternate path is considered, identified and secured.
