Patent CA-2459970-A1 (CA)
Inventor: GUTHRIE DON W
IPC: H01L25/16
Filed: 2002-09-04
Abstract: Zener diodes Z1, Z2 are connected in parallel with sets 201a, 201b of series-connected light emitting diodes L1-L4 with a reverse forward bias orientation.  The threshold voltage of the zener diodes Z1, Z2 is matched to equal, or be just slightly greater than, the forward voltage drops for the light emitting diodes L1-L4 at maximum current. During normal operation, therefore, the zener diodes Z1, Z2 draw virtually no current. Upon failure of one of the light emitting diodes L1-L4, the associated zener diode Z1 or Z2 conducts without increase in the applied voltage, providing an alternate current path maintaining circuit integrity so that other set 201a or 201b of light emitting diodes L1-L2 or L3-L4 connected in series within the circuit 200 continues to illuminate.

Title: Tamper resistant magnetic contact apparatus for security systems
Inventor: BUCKLEY MARK C
IPC: G08B13/08
Filed: 2002-09-13
Abstract: A tamper resistant magnetic contact switch apparatus for alarm systems that has a plurality of magnetic reed switches configured in a logic circuit and a magnetic pack for actuation. A magnetic shield disposed around the switches defines an actuation zone. In combination with the magnetic shield preventing magnetic fields from reaching the switches from locations outside the actuation zone, the magnet pack activates two of the five switches when positioned within the actuation zone to complete the logic circuit, The magnet pack does not, however, activate any of the other switches. If any of the other three switches are activated, or if either of the two activated switches are deactivated, the logic circuit is broken and the alarm circuit is activated.

Abstract: Systems and method implant prostheses in the body. The systems and method provide permanent attachment of the prosthesis in the body. The prosthesis can comprise, e.g., an endovascular graft, which can be deployed without damaging the native blood vessel in either an arterial or a venous system. The endovascular graft can comprise, e.g., a radially expanding vascular stent and/or a stent-graft. The graft can be placed in the vasculature, eg., to exclude or bridge an aneurysm, for example, an abdominal aortic aneurysms. The graft desirably adapts to change in aneurysm morphology and repairs the endovascular aneurysm. The fastening systems (27) and methods can be deployed through the vasculature and manipulated from outside the body, to deliver a fastener (28) to attach the graft to the vessel wall.

Abstract: It is intended to provide a method of efficiently constructing a germline chimeric animal and a method of conveniently constructing a heterozygous animal and a homozygous animal. More specifically speaking, embryonic stem cells (ES cells) are injected into an early embryo (i.e., a blastocyst) which cannot form germ cells due to a genetic cause to thereby construct a chimeric animal carrying germ cells originating in the ES cells thus injected. By crossing male and female heterozygotes obtained from the chimeric animal, a homozygote can be obtained. The chimeric animal thus obtained is highly useful in analyzing gene functions, etc.

Filed: 2002-04-08
Abstract: In a new supplemental combination, the herb, Vitex agnus-castus (chasteberry), enhances hormone balance by increasing luteinizing hormone (LH) and progesterone release and, therefore, ovulation frequency. The antioxidants, green tea, vitamin E, and selenium, improve overall reproductive health. L-arginine, an amino acid, stimulates the reproductive organs by improving circulation. Folic acid, vitamins B6 and B12, iron, zinc and magnesium help promote women's fertility. For men, a combination of L-carnitine, antioxidants, folic acid, zinc and B vitamins can improve fertility. L-carnitine, an amino acid improves sperm quality and motility. Ferulic acid, an antioxidant found in Dong quai, also improves sperm quality. Sperms are highly susceptible to free radical or oxidative damage from environmental toxicants and natural aging. Vitamins C and E, green tea, and selenium are all potent antioxidants that help improve overall reproductive health. zinc and B  vitamins (B6, B 12 and folate) are critical nutrients in male reproductive systems for hormone metabolism sperm formation and motility.

Title: Methods and systems for effecting payment card transactions
Inventor: BARRY GERARD J
IPC: G06Q20/00
Filed: 2003-07-14
Abstract: The present invention relates to card payment systems. In particular, the present invention relates to systems and methods for processing payment card transactions in a dynamic currency conversion and/or multi-currency scheme. To operate correctly, ghost transactions are used. However to prevent duplication of debits against the Card Holder, these "ghost copy" transactions must not be processed into the card schemes with the normal transactions. Thus the Acquirer's and/or third parties host systems have to be amended, in addition to modifications to the related accounting thereof. To overcome this necessity, the present invention provides a method for effecting the performance of a payment card transaction for a first transaction amount in a first currency, between a first merchant and a first payment card holder, the method comprising the steps of a)creating a first payment card transaction record between the first merchant and a second cardholder for the first transaction amount, b) creating a second payment card transaction record between a second merchant and the first cardholder, wherein the second transaction record identifies a second transaction amount in a second currency which equates to the first transaction amount converted into the second currency, and submitting the first transaction record and the second transaction record for processing as payment card transactions.
