Title: Authentication packaging for replacement parts
Inventor: LUPUL TROY D
IPC: B65D5/42
Filed: 1996-05-24
Abstract: The present invention relates to a simple, inexpensive but effective authentication system and package which will enable end users of replacement parts to quickly and easily ascertain the authenticity of the parts contained in the package without necessitating the use of additional authentication equipment. In general, the authentication system for replacement parts of the present invention comprises a package constructed of a multi-layer material such as corrugated cardboard, having located between two of its layers a tear tape. The tear tape is inserted between the layers during manufacture of the multi-layered material and in such a manner that when the material is formed into packages, the tear tape will extend around a substantial portion of the package and cannot be removed without destroying the package or at least rendering it unreusable. Before the tear tape is inserted into the multi-layered material, the tear tape is inscribed or coded with predetermined indicia that is matchable with the part to be contained in the package. Since the tear tape is located between layers of the package material, neither it nor its inscription are visible from either the outside or inside of the package. Once the packaged part reaches its final destination, the end user authenticates the part by removing the tear tape from the package and comparing the inscription to the part contained therein. The manner in which the system is implemented, i.e. by including an operation during the package manufacture which can only be carried out by few companies because of the size and cost of the equipment involved, but which equipment is normally employed during the package manufacture, deters counterfeiting of the replacement parts.

A pair of bendable latching arms (34, 36) project forwardly from the front of the frame for the reception in a central aperture at the rear of the IC card. The frame has a central opening through which a locking pin (150) can slide to lock the arms in the IC card.
Patent CA-2179098-A1 (CA)
Inventor: TSUTSUI KEIICHI
IPC: G11B7/095
Filed: 1996-06-13
Abstract: The invention provides a recording and/or reproduction apparatus for a record medium in the form of a disk by which the necessity for adjustment of an inclination of a head with respect to a disk upon production of the apparatus is eliminated and correct reproduction of data can be assured irrespective of a variation with respect to time. A control circuit controls an offset generation circuit to generate a predetermined offset signal. A skew servo circuit drives a skew motor in response to the offset signal to adjust the relative angle of an optical head with respect to an optical disk to a predetermined angle. A level detection circuit detects the amplitude of the tracking error signal then and outputs it to the control circuit. The control circuit adjusts the offset signal to be outputted from the offset generation circuit so that the amplitude of the tracking error signal may be maximum.

Title: Radio Communication Apparatus and Method
Inventor: NAWATA HIZURU
IPC: H04J3/06
Filed: 1996-06-28
Abstract: A frequency error occurring in a repeater station and a receiving side radio station is determined by using a dummy signal received from the repeater station, and is stored as frequency control data corresponding to the frequency error into a memory.          By controlling a reception frequency based on the stored frequency control data, a data signal received from the repeater station is compensated for the frequency error.  A relatively large frequency error such as the common frequency error occurring in the satellite and the downconverter of the receiving side can be eliminated effectively.

Patent CA-2188647-A1 (CA)
Inventor: CEDERHOLM-WILLIAMS STEWART ANT
IPC: A61K38/00
Filed: 1995-05-02
Abstract: The invention is directed to fibrin materials for use in fibrin compositions and methods that avoid the need to use thrombin as an activating agent for fibrin monomer-based sealants. The invention provides for substantially pure fibrin chains, fibrin chain precursors, fibrin chains with other N-terminal extensions, fibrin monomer, fibrin-homolog and fibrin-analog. The invention further provides for variant fibrin .gamma.-chains. The variant gamma-chain contains one or more mutations and or deletions in the C-terminal region following the coiled-coil forming region such that, when incorporated into fibrin-homolog, the homolog lacks the ability to self-polymerize but has the ability to form non-covalent bonds, and thereby form mixed polymers useful as sealants, with fibrinogen. The invention also provides nucleotide sequences encoding fibrin chains or fibrin chain variants and cells expressing fibrin chains, fibrin chain variants, fibrin monomer, fibrin precursor or fibrogen-analog.  The invention further provides a method of forming fibrin-related proteins in vitro from their component fibrin chains. The invention additionally provides a method for forming a fibrin sealant by reacting a first fibrin-related protein that is incapable of self-polymerizing with a second fibrin-related protein that is incapable of self-polymerizing. Fibrin chains produced by methods of the present invention may be used as sources of substantially pure starting material for the production of important fibrin-derived factors that regulate angiogenesis, platelet aggregation, and other physiological processes.

Abstract: An apparatus and method for monitoring structural changes of an electrode in a rechargeable battery include an in situ x-ray electrochemical cell (30) comprising top and bottom cell members (32, 34) including at least one beryllium window element (36) for transmission of diffractometer x-radiation.  A rechargeable battery (43) mounted within the x-ray cell enclosure comprises an electrolyte/separator element (68) interposed between positive and negative electrodes (64, 66). A current collector element (70) formed of an electrically-conductive open-mesh grid is disposed between the positive electrode and the separator to enable ion-conducting contact of the electrode and separator while maintaining electrical continuity between the electrode and an external x-ray cell terminal (54). As a result of this arrangement, the positive electrode need not contact the window element to establish an electrical battery circuit, but may be sufficiently spaced from the window to avoid electrolytic corrosion of the beryllium element. The in situ x-ray electrochemical cell and battery structure allow for continuous monitoring of the structural changes in electrode materials during charge/discharge cycling.
