Patent CA-2378246-A1 (CA)
Title: Sterilization of biological tissue
Inventor: GIRARDOT JEAN-MARIE
IPC: A01N1/02
Filed: 2000-08-10
Abstract: Allograft tissue prostheses, as well as tissue valves for replacement of defective heart valves and other tissue-engineered products (TEPs), are effectively sterilized by treatment with a coupling agent known to create amide linkages between amines and carboxylic acids in the presence of a protecting agent. The sterilization treatment preferably employs EDC as a water-soluble coupling agent, plus a water-soluble protecting agent which complexes with potentially reactive amine or carboxyl moieties on the biological tissue, in the optional presence of isopropanol or an equivalent alkanol. One preferred sterilization treatment process uses a buffered aqueo us solution where a hydroxymonoamine buffer, such as TRIS plus ethanolamine, provides both the buffering effect and the protecting agents, effectively complexing with potentially reactive carboxyl moieties on the tissue. The treatment is particularly advantageous for sterilizating fresh biological tissue where substantial cross-linking that would alter physical properties of the tissue is undesirable or any tissues or TEPs where a controllable amount  of cross-linking is desired.

Patent CA-2379794-A1 (CA)
Inventor: ORR TOM E
IPC: B25C3/00
Filed: 2002-03-28
Abstract: A connector having apertures to be used to secure different pieces of construction material in relation to each other is provided with structure to hold a nail thereto. This structure permits the nail to be brought into selective alignment with the aperture allowing the nail to be driven home without the workman holding the nail. The invention includes aperture engagement structure which is located in the aperture of the connector. The nail is held in a fastener engagement structure, which has the structure of a sleeve. The fastener engagement structure is attached to the aperture engagement structure on their common first side by a hinge. The fastener engagement structure further has a male portion located on its second side. The aperture engagement structure further has a female portion located on its second side. In a first configuration, the nails are held flat against the body of the connector. When it is desired to drive the nail, the user rotates one or more of the nails into a second, upright position about the hinge.      In this second position the male portion engages the female portion causing the fastener engagement structure and the aperture engagement structure to be locked together. This aligns the nail with the aperture present on the connector.     Once the sleeve is locked in the upright position the user then drives the nail through the aperture securing the connector to the construction material. The sleeve may include a corrugated interior to assist in gripping the nail more firmly in place. Also, the sleeve may be scored so that when the nail is driven, the sleeve splits and falls out of the way.

Title: Dispersion and dispersion slope compensated fiber link
Inventor: SRIKANT V
IPC: H04B10/18
Filed: 2000-08-25
Abstract: Disclosed is a dispersion compensating waveguide fiber suitable for use in high data rate, high light power telecommunications systems of intermediate length. The refractive index profile of the compensation fiber is segmented.  The core region includes three, four, or five, a central segment (28), a fir st annular segment (30), a second annular segment (32), a third annular segment  (34), and a fourth annular segment (36) having different relative refractive  indexes. The segment relative refractive indexes and radii are chosen to provide negative total dispersion and negative total dispersion slope over a n extended wavelength range. The index profile design is flexible enough to provide compensated links having total dispersion that is positive, negative , or zero, while maintaining appropriate total dispersion slope compensation. In addition, the waveguide fiber of the invention may be cabled or otherwise buffered prior to its use in a communications system.

Abstract: L'invention concerne un système et un procédé permettant de brouiller la caractéristique de phase d'un signal de porteuse. Le brouillage de la caractéristique de phase de chaque signal de porteuse comprend l'association d'une valeur à chaque signal de porteuse, et le calcul d'un décalage de phase pour chaque signal de porteuse, basé sur la valeur associée à ce signal de porteuse. La valeur est déterminée indépendamment de toute valeur de bit d'entrée portée par le signal de porteuse. Le décalage de phase calculé pour chaque signal de porteuse est combiné à la caractéristique de phase du signal de porteuse, de façon à brouiller sensiblement la caractéristique de phase des signaux de porteuse. Les bits d'un signal d'entrée sont modulés sur les signaux de porteuse qui présentent la caractéristique de phase sensiblement brouillée pour produire un signal de transmission présentant un rapport valeur de crête sur valeur moyenne réduit.

Patent CA-2398906-A1 (CA)
Title: Sterile water generator
Inventor: JOSLYN LARRY J
IPC: C02F1/02
Filed: 2001-02-05
Abstract: A sterile water generator (B) generates a stream of sterile water on demand. A  water heater (130) heats incoming, unsterile water to a sufficient temperature to achieve sterilization of the water. The sterile water is then passed through a heat exhanger (110) which transfers excess heat from the sterile water to the incoming water. This reduces the energy consumption of the water heater and reduces the temperature of the sterile water ready for use. The sterile water is delivered to a site (A), at which the water is to be used, through a sterile water delivery pathway (C) to avoid recontamination of the water. A first portion (162) of the pathway is pre-sterilized by flowing steam or hot water, generated by the water heater, along the pathway (C). A second portion (212) of the pathway is sterilized with a liquid antimicrobial from the site. The first and second portions of the pathway have at least one common leg (164).

Title: A system and method for using a payroll deduction card as a payment instrument
Inventor: WATKINS KIRK
IPC: G06Q20/00
Filed: 2000-07-19
Abstract: The present invention relates to a system and method for using an e-duction card as a payment instrument, whereby a purchase price of articles purchased on-line or off-line is deducted form an employee's paycheck. The e-duction card is similar to a credit card but is not bound by the same terms and conditions of a credit card. An employer authorizes the inventive system to accept payroll deduction as a payment option for the employer's employees. The employer and/or the system establish guidelines for utilizing the payroll deduction option during commerce and the system stores the guidelines and identifying information for the employer and corresponding employees in a database. Merchants also sign up with the inventive system and agree to accept the e-duction card as a payment instrument. Thereafter, when an employee selects articles from the merchant's web site or store, the employee may use the e-duction card to pay for the selected articles. A magnetic stripe on the e-duction card stores an employee's account information. When a consumer purchases a product and uses the e-duction card as a payment instrument, the account information on the e-duction magnetic stripe is transmitted to a network processor with access to information stored on the database. The processor verifies the employee and merchant status, and the employee account information in order to approve or reject the transaction. This method therefore affords authorized employees the option of using the e-duction card as a payment instrument.
