Patent CA-2400030-A1 (CA)
Inventor: THOMPSON MARC T
IPC: B60L7/28
Filed: 2001-02-13
Abstract: L'invention concerne un appareil de freinage à courants de Foucault comprenant un réseau d'aimants permanents (180, 182, 184) espacés ainsi que plusieurs aimants à flux directionnel (190, 192, 194, 196, 198, 200) que l'on peut disposer dans les espaces entre les aimants permanents. Les aimants à flux directionnel (190, 192, 194, 196, 198, 200) sont orientés de façon à produire une polarité de flux directionnel dont la rotation est de 90· par rapport à la polarité du flux magnétique des aimants permanents espacés (180, 182, 184) dans le but d'augmenter la densité de flux dans l'entrefer ce qui conduit à une meilleure performance du système de freinage. Dans une autre réalisation, on peut utiliser des aimants cubiques (270), chaque aimant étant disposé afin de produire un changement de polarité de flux entre des aimants adjacents. Un élément conducteur électrique capte le flux magnétique fourni par le réseau d'aimants permanents, ces aimants et l'élément conducteur étant montés de façon à permettre un mouvement relatif entre les aimants et l'élément conducteur afin de produire des courants de Foucault dans l'élément conducteur, ce qui donne naissance à une force de freinage entre les aimants et l'élément conducteur.

Abstract: A system and method for permitting purchases over a communication medium such as the Internet is provided. A payment identifier (19) is produced when a purchaser (7) makes a purchase from a merchant (3). This payment identifier (19) is generated by a payment establishment (17). The payment identifier( (19) is communicated to the purchaser (7). The purchaser (17) then takes the payment identifier (19) to a payment establishment (17) to make an in-person payment. The payment identifier (19) does not have to display in human readable form the identify of the merchant (3) or the goods or services purchased. When in-person payment is made at the payment establishment, the merchant (3) is advised, and the purchased goods or services can then be delivered by the merchant (3). The system and method takes away the uncertainty associated with making payment on-line by providing credit card or like details over the communication medium. The payment establishment (17) can be a respected organisation with whom purchases can feel comfortable with in so far as disclosing their credit card or like details. Typically the payment establishment (17) can be a Post Office.

Title: Apparatus and method for reducing the risk of decubitus ulcers
Inventor: SMITH TOBY E
IPC: A61B5/11
Filed: 2001-06-08
Abstract: There is provided herein a sensor for use in patient monitoring situations, wherein the level of patient motion activity is tracked for purposes of determining whether or not that patient has exhibited sufficient activity to merit eliminating a scheduled assisted relocation to a new position. The instant device broadly operates to sense the length of time since a patient has last moved from a previous sitting or lying position. If the patient has not moved during some predetermined time interval, it is preferred that the nursing staff be notified that it is time to manually reposition the patient.  On the other hand, if the patient has changed position within the specified time period, the device will note that fact and inform the attending nurse or other caregiver that the patient need not be moved at the next scheduled relocation, thereby eliminating the need in some cases to rouse the patient from an otherwise sound sleep. In either case, the instant invention operates to reduce the risk that a patient will develop bed sores by helping ensure that the patient manually moved as frequently as is medically necessary, but no more often than is actually necessary.

Inventor: ANDRADE-GORDON PATRICIA
IPC: A61K48/00
Filed: 2001-06-08
Abstract: Here we describe the molecular identification of a cDNA encoding a novel serine protease we have termed D-G. The deduced amino acid sequence, and its  alignment with other well characterized serine proteases clearly indicates that it is a member of the S1 serine protease family. We have found that the  protease D-G mRNA is widely expressed in several tissues throughout the body  including epidermis, fibroblasts, keratinocytes, colon, small intestine, stomach, lung, kidney, bone marrow, lymph node, thymus, ovary, prostate, uterus and spinal cord. Interestingly, this protease contains a hydrophobic stretch of amino acids which is a putative transmembrane near the NH2- terminus. Thus, this serine protease is thought to be synthesized as a type II integral protein. We expressed a soluble form of this novel human protease b y inserting the portion of the protease D-G cDNA, encoding the catalytic domai n, in a zymogen activation construct designed to permit the generic activation of heterologous serine protease catalytic domains. The result is an active preparation of protease D-G that has an activity against a subset of amidolytic substrates. This enzymatically active protease D-G preparation is  now amenable to further biochemical analyses for the identification of physiological substrates as well asspecific inhibitors.

Abstract: Methods, systems and apparatus are provided which prevent frame mis-ordering in an explicitly routed network when switching from a first path to a second path. In a first embodiment, last frame and first frame markers are transmitted, and a receiver buffers all frames received between receipt of the last frame marker and the first frame marker. In a second embodiment, a last frame marker is sent to which an acknowledgement must be received before transmitting on the second path. In a third embodiment, only a first frame marker is sent. The receiver, upon receipt, signals a network card for the first path to stop forwarding frames, also buffers frames for some period. In a fourth embodiment, the merge point node forwards frames over different paths with unique markings so the outgoing card can distinguish them.

IPC: G06F21/00
Filed: 2001-11-16
Abstract: Software applications having a hierarchy of functions, sub-function and sub- sub-functions that are made available to one or more clients (112). The ability of the clients to utilize the various functionality of the applications is controlled by an application security database system (ASDS) (102) which maintains a database (104) of application function hierarchy and client entitlement. The applications consult with the ASDS to determine whether a client's user is authorized to perform a requested function and either performs, or fails to perform, the requested function based on the reply from the ASDS. In particular, rules regarding access to proprietary data associated with different functionality are also maintained by the ASDS. The client entitlements are associated with the end-users of the clients not by user name but, rather, by user roles reflecting the business structure of the client.
