Abstract: A near-infinity image display system (10) has a convex-faceplate cathode ray tube (12) positioned with respect to a concave mirror (14) such that the cathode ray tube (12) is in front of the center of curvature (16) of the mirror (14) and so that the mirror (14) reflects a near-infinity image of the visual display surface to an eyepoint (20) of an observer located below and in front of the center of curvature (16) of the mirror (14) and below the cathode ray tube (12). The cathode ray tube (12) is positioned at a height above the eyepoint (20) of the observer so that it does not interrupt the vertical field of view (24) of the image reflected to the eyepoint (20) of an observer. The concave mirror (12) may be a spherical, ellipsoidal or toroidal mirror. A multiple-display system (30) may be used to create a mosaic reflected image. In the multiple-display system (30), the convex faceplates of cathode ray tubes (12) are placed side by side, and optimally spaced apart at an angle (35) to provide a near-infinity mosaic reflection to an eyepoint (20) of a single observer or eyepoints (40) and (42) of multiple observers. In the multiple-display system (30), multiple observers are spaced apart a distance (41) that optimizes independent viewing of the near-infinity image by each observer.

Abstract: A vibration assembly comprising a housing (12) having a central cavity (20) and a pair of side cavities (22, 24) of radially smaller dimension than that of the central cavity, all of which extends axially about an axis (26) from opposed ends of the central cavity. A piston (50) is housed within the cavities (20, 22, 24) and includes a mass (52) disposed within the central cavity (20) and a pair of supports (54, 56) which are disposed within respective ones of the cavity pair (24, 22) and which extend axially from the mass. The supports (54, 56) have radial dimensions which are substantially the same as those of the pair of cavities (22, 24). The mass (52) and the supports have axial dimensions which are substantially less than those respectively of the central cavity means and of the pair of cavities (20, 22, 24) for enabling the piston (50) to move axially within the cavities. Air inlets (61, 62) in the housing and conduits (66, 68) in the piston enable the piston to reciprocate within the housing for repeated impact against an impactor (38) for transmission of energy thus obtained to a test table and an item under test.

Abstract: The invention is an improved distributed information system which automatically provides for the transmission of security protocol data units between end-users of a distributed information system. The invention includes a processor (14) that compares the adress and security key of a received security protocol data unit to stored end-system addresses and security key information stored in memory (10, 12) and, in the absence of an existing end-system (B) address and security key, includes a processor (20, 24) to automatically initiate negotiation of a security key between end-systems (A, B) and then confirms the negotiated security key and initiates a security protocol transmission of the data unit using transmitters and receivers (18, 20) and protocol processors (19, 28).

Abstract: Optically sensitive materials such as sensors (18) or the human eye are passively protected (10) against overexposure to high intensity light (20) in the visible range using a reverse saturable absorber (14) organometallic cluster compound having a core of at least two multiply-bonded transition metal atoms selected from group 8, 6b or 7b of the periodic table. The core atoms are bound together with ligands that permit the formation of a complex. A preferred organometallic cluster compound is cyclopentadienyl iron carbonyl tetramer. As the intensity of incident light increases, the intensity of transmitted light also increases up to a saturation level, but above the saturation level the transmitted light intensity remains substantially constant even with increasing incident light.

Abstract: An improved curing oven is disclosed. The present invention (10) provides an improved curing oven which cures materials with electromagnetic radiation in the ultraviolet region. The invention consists of a surface (12) lined with a layer of material (14) effective to radiate ultraviolet radiation in response to the application of infrared radiation. In a specific illustrative implementation, the invention (10) includes a second surface (18) overlying the first surface (12) providing a passageway therebetween. The oven temperature is set and maintained by a conventional temperature controller (20). Tne temperature controller (20) measures the oven temperature and controls a valve (22) which adjusts the gas pressure from a gas supply (24) to a set of oven burners (26). Air is supplied through inlet ports (28) included in the second surface (18).

Abstract: A method and apparatus for non-contact measurement of the viscosity of a liquid such as paint. In accordance with the method and apparatus, the surface of a liquid is perturbed with a standing wave of predetermined wavelength. This perturbation is effected by directing a burst of air against the surface of the liquid using periodically spaced air nozzles. The frequency and rate of decay of the induced surface wave is measured using typically optical means including a reflected light beam. The measured frequency and decay rate are combined with the known depth of the liquid sample in a computing circuit to provide a measurement of fluid viscosity.

Abstract: An electrical circuit component is temporarily fixed to a temporary substrate. Electrical contacts on the component are interconnected with corresponding contacts on the test substrate by lead wires or ribbons using a bonding wedge that forms the lead wires into a gull-wing shape with central portions thereof formed adjacent to edge portions of the component. The component is subjected to a test procedure while fixed to the temporary substrate via signals applied to the contacts thereof. The lead wires are then severed near their connection to the temporary substrate, and the component with the remaining lead wire portions attached is removed from the test substrate. The lead wires are sufficiently stiff and/or are adhered to the edge portions of the component with an adhesive so as retain their shapes after removal of the component from the temporary substrate. The component is then adhered to a permanent device substrate, and the ends of the lead wires are bonded to corresponding contacts on the device substrate.

Abstract: An electrical circuit pattern (52) is formed on a glass-ceramic, thermally fusible tape (50). The tape is heated to a temperature at which it becomes temporarily plastic, and is then bent into a desired non-planar shape. Further application of heat causes the tape to be sintered in the non-planar shape. A multi-layer structure can be provided by laminating plural layers of Low-Temperature-Cofired-Ceramic (LTCC) tape (10, 12, 14) with respective circuit patterns (10a, 12a, 14a) formed thereon together, and plastically bending the laminated structure into the non-planar shape during the heating step. A circuit struture including an edge connector (50b) can be formed by laminating a layer of glass-ceramic transfer tape having an electrical circuit pattern which includes conductor strips (52c) formed on an edge connector portion thereof onto a relatively rigid substrate (54), such that the edge connector portion is bent around an edge of the substrate to form a rigid edge connector. The edge connector portion of the transfer tape which is formed into a non-planar shape during the lamination step, is fused together with the remaining portion of the transfer tape onto the substrate during the heating step.
