Abstract: A security enhanced computer system arrangement includes a coprocessor and a multiprocessor logic controller inserted into the architecture of a conventional computer system. The coprocessor and multiprocessor logic controller is interposed between the CPU of the conventional computer system to intercept and replace control signals that are passed over certain of the critical control signal lines associated with the CPU. The multiprocessor logic controller arrangement thereby isolates the CPU of the conventional computer system from the remainder of the conventional computer system, permitting separate control over the CPU and separate control over the remainder of the computer system. By controlling the control signals that are normally passed between the CPU and the remainder of the computer system, the multiprocessor logic controller permits the coprocessor to perform highly secure operations.

Abstract: In a semiconductor fabrication method for forming a transistor structure upon a semiconductor substrate, a nitride layer is also formed over the semiconductor substrate. A gate oxide layer is formed over a region of the semiconductor substrate. The gate oxide layer has a relatively thinner oxide region over the nitride layer and a relatively thicker oxide region over the substrate adjacent the nitride layer. A transistor gate is formed extending over the relatively thinner oxide region and over the relatively thicker oxide region. The transistor thus formed is therefore asymmetric. A first transistor active region is formed in the vicinity of the relatively thicker oxide region and a second transistor active region is formed in the vicinity of the relatively thinner oxide region. The nitride layer can be formed by rapid thermal nitridization of the semiconductor substrate. The relatively thinner oxide region can be one-half as thick as the relatively thinner oxide region.

Abstract: A swivel exhaust conduit for rotatably connecting a patient mask to the delivery conduit of a positive pressure air supply. The swivel exhaust conduit design provides an exhaust port that utilizes the rotating bearing of the swivel conduit's rotating two-piece design for permitting and directing exhaust of CO.sub.2 laden air. A baffle chamber formed in the clearance of the two pieces provides an area where noise is reduced. As CO.sub.2 laden exhaust exits the swivel exhaust conduit, it is directed away from the patient mask and down the outside of the delivery conduit via a slit pattern on the swivel conduit.

Abstract: A high speed non-contact beam scanning device sized and shaped to provide the ergonomic benefits of a pen or wand, yet can scan a wide angle moving beam across an information-bearing target in one or two dimensional scan patterns such as lines, rasters or other patterns in order to read information therefrom. The device is well suited for reading one or two dimensional bar-code or other printed matter. In order to achieve the high density optical packaging necessary for its high performance to size benefits the device employs a novel in-line or "axial" gyrating, or "axial" scan element. The axial scan element can accept an input light beam at one end and cause the light beam to emerge from its opposite end as a scanned beam, propagating in the same general forward direction the light beam had upon entering the element. Reflected light, which carries information contained on the target, is collected by an internal non-imaging light collector and is processed by signal processing electronics.

Abstract: A method for correcting the shape of a semiconductor structure. According to the method the shape of a semiconductor structure is initially determined to discern the presence, location and magnitude of structural deformities including warp and bow. Information derived from the topography of the structure is then used to control a heating apparatus. More particularly, individual zones or elements of a multiple zone heating assembly are selectively controlled to direct heat radiation of nonuniform intensities toward different regions of the structure to effect non-isothermal conditions within the structure and thereby reduce deformities that were determined to be present in the structure prior to shape correction.
