Abstract: A card package production system (10) with interchangeable inserters (24A, 24B) and carrier folders (86A, 86B) to enable use of forms (26A, 26B) of different types verifies the carriers (30) if they are properly produced and rejects them if they are not prior to the attachment to a carrier. The embossed characters and encoding read from the card are compared with the stored card data to verify accuracy and are compared to coding on the carrier form (26A, 26B) to determine if there is a match. A code on the carrier is also compared to stored carrier data and to the cards provided for insertion and are rejected without cards if incorrectly prepared.

Abstract: The present invention provides a set of holding pattern entry algorithms used to define flight segments for entry into holding patterns. These geometries preferably describe the specific location and distance of various segments used in the holding pattern and holding pattern racetrack, with each segment defined as a curved or straight segment between endpoints. The algorithms also preferably include criteria used to determine entry extension, maximum initial turn angle, and minimum distance between a hold fix and an entry turn point. The geometry also preferably extends entry distance to avoid excessive iterative calculations. The algorithms are preferably utilized by a flight management system and method that determines segment sequencing during entry into holding patterns and the holding patterns themselves.

Abstract: A module locator has a generator that provides to each of a series of module slots in a mainframe, a signal having a unique signature. Each module interfacing with a module slot has an associated receiver that receives the signal through the module slot and reads the unique signature of the signal provided by the generator. The unique signatures read by the receivers are typically reported to a host processor associated with the mainframe when queried, so that the location of the module within the series of module slots can be established.

The fringe pattern detection system measures an interference fringe pattern of the unknown signal. The power detecting system measures relative power of the unknown signal before the unknown signal enters the fringe pattern detection system. The relative power of the unknown signal is used to compensate for modulation within the unknown signal.

Abstract: A feedback position control system and method enable an optical element in a variable arm of an interferometer to be varied according to a predesignated motion profile. The system and method detect a reference optical signal that varies in intensity according to a position of the optical element in the variable arm. The system and method receive the detected reference optical signal, derive a motion profile from the detected reference optical signal and compare the derived motion profile to the predesignated motion profile to generate a control signal based on a deviation between the derived motion profile and the predesignated motion profile. The control signal is used to adjust the position of the optical element in the variable arm of the interferometer to minimize the deviation between the derived motion profile and the predesignated motion profile.

Abstract: A linear translation apparatus for optical systems has a tube and a piston that slides along an inner wall of the tube that is disposed about a longitudinal axis. An optical element mounted on the piston intercepts optical signals entering the tube so that optical path lengths within the optical system are varied as the piston moves along the longitudinal axis. The piston has a magnetic moment enabling the piston to slide along the inner wall in response to the strength and direction of a magnetic field generated by a magnetic actuator. A driver coupled to the magnetic actuator establishes the strength and direction of the generated magnetic field to achieve a predesignated motion profile for the piston along the longitudinal axis.
