Abstract: For use with a physical document bearing content visible when illuminated by light in the human visible spectrum, a tag printer, a verifier and a document processing system employing one or both of the printer and the verifier. In one embodiment, the tag printer includes: (1) a processor operable to generate metadata regarding the physical document and (2) a printer associated with the processor and operable to print a tag containing the metadata on a location of the physical document irrespective of locations of the content using an ink substantially invisible in the spectrum.

Abstract: A splice closure contains multiple splice trays that can be individually pivoted and accessed so that the splice closure is capable of optimally carrying and providing access to numerous optical fibers and optical fiber splices. The splice closure has a housing defining an internal cavity and at least one opening to the internal cavity. An end cap is capable of occluding the opening of the housing to provide an enclosed configuration. A support frame has opposite front and rear ends, the front end of the support frame is connected to the end cap, and the support frame is capable of being positioned within the internal cavity of the housing during the enclosed configuration. The support frame extends in a longitudinal direction between the front and rear ends, and defines a frame axis that extends in the longitudinal direction.

Abstract: A closure that is operative for containing optical fiber splices includes a support assembly that supports the splices. While the closure is in an enclosed configuration, the support assembly and a holding bracket are substantially contained in a housing of the closure. When the splices within the closure are to be serviced, the support assembly and the holding bracket are removed from the housing. Thereafter, the holding bracket is configured so a protruding portion of the holding bracket extends away from the support assembly to provide an extended configuration. While in the extended configuration, the protruding portion of the holding bracket is clamped to a work surface with a clamping device so the holding bracket supports the support assembly in a cantilever-like fashion and the holding bracket and the clamping device do not substantially interfere with the servicing of the optical fiber splices.

Abstract: An actuating device for use in moving a school bus safety unit, such as a stop sign or crossing arm, between a retracted position adjacent the school bus, and an extended position projecting outwardly from the bus. The actuating device includes a drive motor and a friction-type slip clutch which permits the safety unit to be manually moved from its extended or retracted positions without damage to the drive arrangement for moving the safety unit, and several alternative control circuits may be utilized to automatically or semi-automatically return the safety unit to its retracted and/or extended positions if manually moved therefrom.

Abstract: An improved actuating device for school bus safety unit, such as crossing arms and the like, which includes an arrangement for driving and controlling the crossing arm in a continuous predetermined arcuate path of movement, with the safety device being moved continuously back and forth in a sweeping motion that provides a moving barrier in areas adjacent the school bus where children may be placed in an unsafe situation, such as immediately adjacent the front bumper of the bus which is outside of the normal line of vision of the school bus operator. In one embodiment, an extendable line is anchored to the bus at one or both ends, and an intermediate portion of the line is engaged by the moving safety unit, whereby the line itself creates a changing barrier as the safety unit sweeps through its path of movement.

Abstract: A crossing arm unit for use on the front of school buses and the like to protect children walking in front of the school bus, the crossing arm unit including a frame attached to the front bumper of the school bus, and a movable arm pivotally mounted in the frame for movement between a retracted position along side the bumper and an extended position projecting outwardly from the bumper.
