Abstract: A conveyance system that transports fabric comprises a work space having a surface that the fabric can be transports across, and at least one budger that moves and/or provide force to the fabric in a servo controlled motion.

Abstract: Embodiments of the invention are directed to medical transport devices, more particularly, to spineboards. In one embodiment, a spineboard includes an upper panel assembly joined to a lower panel assembly by one or more latch assemblies and one or more hinge assemblies. An upper moveable belt wrap about the upper panel assembly and is driven by a motorized drive roller while a lower moveable belt is wrapped about the lower panel assembly and driven by a separate motorized drive roller. The upper and lower moveable belts counter-rotate relative to one another. The upper moveable belt is used to load and unload an injured person from the spineboard while the lower moveable belt is used to advance the spineboard toward and away from the injured person.

Abstract: A continuous feed coater for coating a length of substrate with vaporized or sprayed material, is disclosed. A specific example is a roll-to-roll coater which includes two lower supply rollers for supporting two webs of uncoated material, and two upper take-up rollers for supporting the webs after they are coated. A central web-support forms a plenum that acts as a deposition chimney or chamber by bringing the two webs into close proximity to each other to form two large walls of the plenum. The ends of the webs are sealed using side dams to form the chimney with a rectangular cross section such that the vapor cannot exit from the edges of the material. The vaporized coating constituents to be deposited on the rolled material are directed into the deposition plenum from a coating material supply source located at the bottom of the plenum, and are exhausted through the top of the plenum.

Abstract: A technique for verification of a complex integrated circuit design, such as a microprocessor, using a randomly generated test program to simulate internal events and to determine the timing of external events. The simulation proceeds in two passes. During a first pass, the randomly generated test program and data vectors are applied to a simulation model of the design being verified. During this first pass, an internal agent collects profile data about internal events such as addresses and program counter contents as they occur. During a second pass of the process, the profile data is used to generate directed external events based upon the data observed during the first pass. In this manner, the advantages of rapid test vector generation provided through random schemes is achieved at the same time that a more directed external event correlation is accomplished.

Abstract: A method of testing a circuit design is provided which allows for the comparison output of an abstract reference model of the circuit and the circuit itself to the same set of input stimuli. The circuit under test may operate in a manner which produces unpredictable events, results, or data. Due to the nature of the reference model, unpredictable results, data, or events are not allowed to occur. Thus to compare the outputs of the two as a means of verifying the circuit design, the testing method allows for a comparison analysis of the outputs despite the possibility of unpredictable data and events occurring on the circuit and not the model.
