摘要:
A secure device (1) has a circuit board (2) with various exposed components such as an LCD (4) and keys (40). A secure circuit (10) is housed within an enclosure formed between the board (2) and a cover (11). The cover (11) has, on its inside surface, a security track (23) in a dense serpentine pattern. The board (2) has a security track (52), also in a dense serpentine pattern, is an inner layer. The track (52) is linked to covered surface-level tracks (27) by vias (64). The cover's security track (23) is connected to the board's security tracks (52, 27) via a deformable pad (25) whose conductivity increases with applied compression.

The present invention is directed to processes for the preparation of N-(3R, 3aS, 6aR)-hexahydrofuro[2,3-b]furan-3-yl-oxycarbonyl-, (4S,5R)-4-[4-(2-methylthiazolo-4-methyloxy)-benzyl]-5-i-butyl-[(3,4-methylenedioxyphenyl)sulfonyl]-aminomethyl-2,2-dimethyl-oxazolidine.
摘要:
One aspect of the invention includes and method of generating virtual autostereoscopic images using a computer. The method may include defining at least one object in a virtual three-dimensional space and defining a virtual point of view. Images may be generated by simulating a parallax scanning motion of the at least one object. The generated images and be displayed and stored.

A pair of brazed sheets or plates having abutting portions through which aligned openings are formed, the opening through one sheet being larger than the opening through the other.
摘要:
A heat exchanger in which a heat exchanger core is disposed within a casing which includes a side wall formed by bending a plate into the form of a sleeve in which edges of the plate are in adjacent, confronting relationship with an inwardly projecting, transversely extending deformation, the deformation being disposed between a pair of press members with one of the press members being transversely inserted within the sleeve. The press members are moved together to remove the deformation with resultant pivoting of the edges into abutting contact or overlapping relationship. The heat exchanger core is formed of a plurality of stacked plate pairs each having a plate in inverted orientation. Outwardly projecting ribs of anticlastic form are so formed in each plate that the ribs on each plate of each plate pair are interengagingly intersect with the ribs on the adjacent plate of the adjacent plate pair accurately to align the plate pairs in the heat exchanger core.
摘要:
A support surface that utilizes repulsive forces of opposing magnetic fields is described. In preferred embodiments, the support apparatus includes first and second frame members having first and second pluralities of magnets disposed thereon. The pluralities of magnets are oriented such that the first plurality of magnets produces a magnetic field having an orientation that opposes the magnetic fields of the magnets of the second plurality. The first and second frame members interact such that they maintain a substantially static lateral position relative to each other despite the repulsive forces of the opposing magnetic fields. A support member, such as a cushion member, is disposed adjacent one of the frame members, and can be connected thereto. A covering can surround the entire assembly. In particularly preferred embodiments, the frame members have dimensions similar to those of conventional mattresses, and the cover confers the appearance of a conventional mattress onto the support apparatus.
摘要:
A sanding apparatus (1) is provided with a platen (2) formed of several layers and with a flat surface to which an abrasive sheet is attached. The platen (2) has a peripheral edge (7) with at least one point (4). A conductive means (18, 20) is provided through the layers of the platen (2) to act as a heat sink adjacent to the point (4) to remove heat from the surface point (4).
