Patent CA-2362962-C (CA)
Title: A system for providing an integrated circuit with a unique identification
Inventor: LOFSTROM KEITH
IPC: H01L23/544
Filed: 2000-02-11
Granted: 2008-05-13
Abstract: An integrated circuit identification device (ICID) (38) to be incorporated into an integrated circuit (IC) (40) includes an array of electronic cells (46) in which the magnitude of an output signal of each cell is a function of randomly occurring parametric variations which vary from cell-to-cell. The ICID (38) also includes a circuit for measuring (50) the output of each cell and for producing output data having a value reflecting the particular combination of measured characteristics of all of the elements of the array (46). When we make the number of elements in the array (46) large enough, we insure that to a high degree of probability, the pattern of measured array cell characteristics for an ICID (38) embedded in any one IC (40) will be unique and distinguishable from such patterns measured by ICIDs (38) embedded in millions of other ICs (40). Thus the value of the output data produced by an ICID circuit (38) acts as a unique "fingerprint" for the IC  (40) in which it is installed, and can be used as a unique identification (ID) for that IC (40).

IPC: F02C7/04
Filed: 2000-08-09
Granted: 2006-04-18
Abstract: A supersonic external-compression inlet (20) comprises a generally scoop- shaped supersonic compression section for diffusing a supersonic free stream flow (24). The supersonic compression section includes a main wall having a leading edge (28) and a throat portion downstream of the leading edge (28), and side portions joined to opposite side edges of the main wall so as to fo rm a generally scoop-shaped structure. The side portions advantageously extend into the supersonic flow stream far enough to encompass the initial oblique shock wave that is attached to the leading edge of the main wall. The main wall has an inner surface (22) formed generally as an angular sector of a surface of revolution, the inner surface (22) of the main wall coacting with inner surfaces of the side portions to define a three-dimensional external- compression surface. The supersonic external-compression inlet (20) also includes a subsonic diffuser section arranged to receive flow from the supersonic compression section and to diffuse the flow to a subsonic condition. A variable-geometry inlet includes an external ramp hinged about its forward edge and forming a portion of the inner surface of the scoop- shaped diffuser, pivotal movement of the external ramp serving to vary a throat size of the inlet. The subsonic diffuser (20) includes an internal ra mp hinged about its aft edge for maintaining a smooth transition from the external ramp.

Abstract: A data distribution system provides capability for synchronised delivery of data elements to each of a set of receivers In the system, a number of forwarding computers are linked together in a predetermined configuration by a communications network. An originating forwarding computer receives a data element from a source and forwards it to one or more predetermined destination forwarding computers of the system for delivery to receivers. Each forwarding computer operates a cyclical monitoring process to measure at least one characteristic known to contribute to delay in transferring a data element between forwarding computers, calculating the maximum expected delay for each cycle. On forwarding a data element, an originating forwarding computer calculates a prescribed time for delivery to a receiver by a destination forwarding computer taking account of the maximum expected delay at that time, writing the prescribed delivery time into the data element being forwarded. The system is adaptive to varying network performance in maintaining synchronised delivery.

Abstract: A tibia fixturing device comprises a metal tray formed with annularly spaced recesses in its underside at a depth of at least about 1.5 mm and from which a stem depends for axial insertion into a tibia conical cavity. The stem has a circular cylindrical portion proximal the tray and a conical portion distal the tray. Fins radially extend from the stem cylindrical portion and penetrate the tibia to provide some torsional resistance. Axially extending channels are formed about the stem periphery which channels have bottom surfaces parallel to the stem axis to provide further torsional resistance. The channels are arranged to not interlock with the cement in the axial direction to permit the cement to separate first from the device during axial removal of the device from the bone. The fins have inclined edges distal the tray and inclined radial outer edges to align and center the stem to the bone cavity edge. Cement in the tray recesses bonds the tray to a tibia resected surface to provide major torsional resistance of the tray about the cavity longitudinal axis.
