Patent CA-2398441-A1 (CA)
Title: Method and apparatus for balanced electronic operations
Inventor: XIAO JAMES ZHENGCHU
IPC: G06K19/073
Filed: 2001-02-19
Abstract: As microprocessors and other electronic devices become faster and employ higher component densities, the noise generated by the transitions between data states has an increasing influence on the performance and security of these devices. Calculations and processes performed with the method of the invention will have a constant number of bit transitions, so ground bounce a nd similar effects are minimized. In the preferred embodiment, this is done by replacing leaky software processes with lookup tables filled with output dat a corresponding to outputs of a software process indexed with corresponding operand values. The invention is particularly useful in smart card implementations using DES (data encryption standard) protection, which may b e cracked by monitoring the power signature while data is being processed.</SD OAB>

Title: Medicament dispensing device with a multimaterial diaphragm bounding a pneumatic force chamber
Inventor: HOLROYD MICHAEL
IPC: A61M11/00
Filed: 2001-06-08
Abstract: A metered dose inhaler for use with a pressurized aerosol container (25) which is preferably breath-actuated. A preload (460) is applied to the internal aerosol valve by an amount sufficient to result in a dose release, but this is prevented by the application of a pneumatic resisting force. The inhaler comprises a release device (520) which, upon actuation, releases the resisting force and allows the preload to actuate the aerosol valve. A metered dose of medicament is then released for inhalation by the patient. The pneumatic resisting force is established by a negative pressure region (600) defined in part by a diaphragm (440). The diaphragm (440) includes a central disk (441) of a first, relatively high stiffness material "A" and a peripheral ring, coupled by a flexure of a second, relatively low stiffness material "B".

Title: Method and system for interfacing with a shipping service
Inventor: SCHOMMER ROBERT J
IPC: G06Q10/06
Filed: 2001-10-05
Abstract: A logistics node receives a purchase order from a customer. The logistics node selects an appropriate carrier to transport products specified in the purchase order and conveys shipping instructions to the selected carrier. The logistics node also coordinates the shipment by interacting with a source node (106) associated with a supplier and a destination node (102) associated with the recipient. The logistics node provides an interface that permits users involved in the distribution chain to track the status of the shipments without having to enter tracking codes that are unique to individual carriers.  The interface allows a user to access multiple "levels" of information regarding a shipment, including information pertaining to an individual product within a shipment containing multiple products. The interface provides different "views" for use by different respective users. Each of the views provides a corresponding set of tools for use in interacting with the freight managing service.

Abstract: Engine (30) has a compression fan (36) coaxially mounted with reaction membe r (38). Casing (32) extends around reaction member (38) to form volute (52) an d extends to turbine wheel (54) which is connected to compression fan (36) via axle (40). Reaction member (38) comprises vanes (60), flame grid (62) and supporting members in the form of side casings (64). A mixture of fuel and a ir enters engine (30) via inlets (34). The mixture is drawn into compression fa n (36) which causes an increase in the pressure of the mixture. From the compression fan (36) the mixture is directed towards the reaction member (38 ). Because the compression fan (36) is rotating in a first sense and the reacti on member (38) is rotating in a second sense, the velocity of the fuel and air mixture entering the reaction member (38), relative to the reaction member (38), is approximately the sum of the external rim velocity of the compressi on fan (36) and the internal rim velocity of the reaction member (36). The mixture is burnt within the reaction member (38) and the vectored gases caus e the rotation of the reaction member (38) in the second sense.

Title: Combination dissector and expander
Inventor: YOUNG RODERICK A
IPC: A61B17/32
Filed: 1997-06-30
Abstract: A combination tissue dissector and long term expander is disclosed for use in plastic surgery applications and other applications where it is desirable to dissect a tissue pocket, and serially expand the dissected pocket through long term tissue expansion. The combination device performs the separate functions of dissection, and long term expansion in a single balloon package. In an exemplary embodiment, three sheets of substantially inelastic material (45, 47, 48) are bonded together at their outer margins to form two discrete inflatable chambers (49, 51). The lower inflatable chamber (49) defined by the middle and lower balloon sheets (45, 47) is further welded together at various points (50) over the sheet's surface area to create a semi-rigid base portion (44) which provides a fiat well-defined footprint for the balloon. The semi-rigid base portion (44) prevents further enlargement of the tissue pocket at the margins when the device (32) is utilized as a tissue expander. In a preferred method of use for the combination device, the combination device is tunneled bluntly to a desired location within the body. The device (32) is then inflated to dissect tissue layers along natural tissue planes and create a tissue pocket. After dissection, the combination device may be left within the body as a temporary implant to further expand the tissue pocket through long term expansion until the desired tissue pocket volume is achieved.
