Patent CA-2117184-A1 (CA)
Title: Binary encoded multiple frequency rf identification tag
Inventor: HUTCHISON DONALD W
IPC: G06K19/067
Filed: 1992-05-18
Abstract: A tag (10) for identifying an item to which it is attached includes an inductance (L) connected in parallel with a capacitance.  The capacitance includes a plurality of individual capacitors (C1, C2, C3, C4, C5), each of a predetermined different capacitance.  The individual capacitors (C1, C2, C3, C4, C5) are connected to the inductance (L) to establish a resonant circuit (20) having a predetermined resonant frequency. At least one of the capacitors (C1, C2, C4) includes a dimple (12) for shorting the capacitor when the tag (10) is exposed to electromagnetic energy at the predetermined resonant frequency. The shorted capacitor establishes a second resonant frequency which may be used to identify which capacitor (C1, C2, C4) has become shorted. A binary "1" is assigned to either the shorted capacitor (C1, C2, C4) or the non shorted capacitor (C3, C5) and a binary "0" is assigned to the capacitors which are not assigned a binary "1", the binary "1"s and "0"s combining to establish a numeric code uniquely associated with the tag (10).

Title: Preparation of a skin surface for a surgical procedure
Inventor: KHAN MOHAMMAD A
IPC: A61K9/70
Filed: 1994-08-12
Abstract: Abstract of the Disclosure A film forming composition for preparation of a skin surface as a surgical site includes a film forming material and a antimicrobial agent soluble in a fugitive solvent. The composition when applied to the skin surface forms a substantially water insoluble, substantially tack-free flexible film adherent to the skin surface. The film is capable of releasably retaining the antimicrobial agent to substantially inhibit microbial growth on the skin surface. The film releases sufficient antimicrobial agent to substantially eliminate the microorganisms normally present on the skin surface to prepare the surface for the procedure and continues to release the antimicrobial agent during the procedure and subsequent wound healing. A preferred embodiment of the composition includes at least one compound for providing a first color indicative of the skin surface area covered by the composition and develops a second color upon the substantial elimination of the fugitive solvent indicating that the site is ready. A method for use of the composition to prepare a skin surface for a surgical procedure includes providing the composition, observing the first color for indicating the skin area covered and the second color indicating that the fugitive solvent has substantially evaporated. A single use kit for preparing a skin surface for a surgical procedure includes a non-resealable unit container of the film forming composition and an applicator in a non-resealable package.

Patent CA-2133054-A1 (CA)
Inventor: RIVARD COREY M
IPC: B62D25/12
Filed: 1994-09-27
Abstract: An attenuated hinge spring assembly for a trunk lid of an automotive vehicle includes a coiled spring which is connected to a bracket secured to the vehicle, a threaded stud which is secured to the bracket, a plate which is slidably mounted on the bracket and the stud, a nut rotatably attached to said threaded stud and selectively secured to an arm, and a washer which lies between the plate and the nut.  The plate lies adjacent to the coiled spring.  The arm is pivotally connected to the trunk lid and to the bracket.  The spring is connected to the stud and the arm and uncoils as the arm pivots from a lowered position to a raised position to move the lid between a lowered position and a raised position.  When the lid is raised, the arm rotates which causes the nut to rotate and translate along the stud, which in turn causes the washer and plate to translate along said stud.  The plate moves against the coiled spring and frictionally brakes the spring and the nut to slow the momentum of the lid as the lid is being raised.

Title: Case nitrided aluminum product, process for case nitriding the same, and nitriding agent for the same
Inventor: YAMADA YASUHIRO
IPC: C23C8/02
Filed: 1994-10-05
Abstract: A case nitrided aluminum product is produced by contacting an aluminum product with a nitriding agent at a part of a surface thereof at least, and by nitriding the aluminum product at the surface with an ambient gas at a temperature of a melting point of the aluminum product or less while keeping the aforementioned contact. The nitriding agent includes an aluminum powder, and the ambient gas virtually includes a nitrogen gas. The resulting nitriding layer has a depth of 5 micrometers or more, and it exhibits a case hardness of from 250 to 1,200 mHv. Thus, it is possible to form the deep and hard nitriding layer on the aluminum product with ease under the conditions where it has been said to be too difficult to nitride aluminum products. The case nitrided aluminum product can appropriately make sliding parts which require high wear resistance.

Title: Addressing a matrix-type liquid crystal cell
Inventor: SURGUY PAUL WILLIAM HERBERT
IPC: G02F1/133
Filed: 1993-10-04
Abstract: A liquid crystal cell comprising a matrix of pixels defined by areas of overlap between members of first and second sets of orthogonal electrodes has its pixels selec-tively set to first and second states by addressing the pix-els in rows. The pixels of a given row are first set to a first state by applying an erase signal (12) to the corresponding row conductor simultaneously with applying bipolar data signals (8, 9) to all the column conductors. Selected pixels of the row are subsequently set to a second state by apply-ing a strobe signal (10) to the row conductor simultane-ously with applying a bipolar data signal (9) to the rele-vant column conductors, another bipolar data signal (8) being applied to the column conductors corresponding to non-selected pixels. The start of the strobe signal coin-cides with the start of the active central portion of the data signals but the strobe signal continues beyond the end of this portion, enabling the addressing rate to be increased.
