Title: A client-centric internet shopping system, method and program
Inventor: DUTTA RABINDRANATH
IPC: G06Q30/06
Filed: 2001-02-15
Abstract: A system, method and program of the invention enables a client in a network of computers to participate with a plurality of merchants across several Web servers in electronic transactions for the purchase of products from the merchants. The client is enabled to make one transaction with one merchant dependent upon the results of another transaction with another merchant. More specifically, each item that is available from any merchant and is selected by a customer using the client is represented at the client as a separate object having states associated therewith. A buy, hold, or conditional state will set a lock on the corresponding object at the Web server such that no other transactions with other customers can take place for that specific item while the current customer is actively using it. A conditional state sends a signal to the merchant to assist in contacting another merchant in order to cancel a previous transaction that the other merchant had with the current customer.

Patent CA-2351020-A1 (CA)
Inventor: DAVIS SIMON PAUL
IPC: H04L12/54
Filed: 2001-06-18
Abstract: The invention relates to a switching device (300) having a plurality of line interface cards (LICs) (310), a plurality of egress LICs (320), a cross-bar (330) and a management card (340). The switching device (300) routes fixed sized cells of data across the cross-bar (330). The cells comprise fragments of variable length data packets. Each ingress LIC (312, 314, 316) is associated with a respective schedule or timetable (362, 364, 366) governing the transmission of cells by the ingress LIC. Similarly, each egress LIC (322, 324, 326) is also associated with a respective schedule or timetable (382, 384, 386) governing the reception of cells by said egress LIC. The schedules are in the form of a table whose entries are the identities of transmission queues corresponding to a respective egress LIC identification number (for ingress LICs) and ingress LICs from which to receive (egress LICs). Each ingress and egress LIC maintains a pointer into its associated schedule. At each cell transmit time, each ingress LIC transmits a cell from the queue identified by the pointer and each egress LIC will receive the cell from the ingress LIC identified in the entry referenced by the pointer. The pointers then move to the next location. Each schedule is circular in the sense that when moving the pointer from the last entry, its next position is the first entry.

Patent CA-2356342-A1 (CA)
Title: Piezoelectric micropump
Inventor: ZIMLICH WILLIAM C JR
IPC: B81B3/00
Filed: 1999-12-21
Abstract: A piezoelectric micropump (10) is disclosed for pumping fluid from a container (14) to a delivery point in low volumes and at controlled flow rates. The pumping action is created by movement of two or three diaphragms (40, 42, 44). The movement of each diaphragm is caused by expansion and contraction of an attached piezoelectric actuator (46, 48, 50). Coordination of the movement of the diaphragms (40, 42, 44) creates unidirectional flow of the fluid. The piezoelectric actuators (46, 48, 50) are cantilevered between the pump body (22) and the diaphragms (40, 42, 44) to provide greater deflection of the diaphragms (40, 42, 44).  The piezoelectric actuators (46, 48, 50) preferably are piezoelectric bimorphs such that the diaphragms (40, 42, 44) can function as both seals and pumps.
Patent CA-2357246-A1 (CA)
Inventor: OHHIRA RISATO
IPC: H04B10/50
Filed: 2001-09-12
Abstract: In an optical transmitter which modulates a continuous-wave optical carrier with an electrical data pulse, the carrier is modulated with a clock signal having 1/2n (where n is an integer equal to or greater than unity) of the frequency of a fundamental sinusoidal component of the data pulse so that the modulated carrier contains at least a center frequency spectral component. On the modulated optical carrier a filtering operation is performed so that the filtered carrier contains a carrier frequency component and first sideband components. Before or after the clock modulation is performed, the data pulse is used to perform data modulation on the optical carrier.
Patent CA-2361712-A1 (CA)
Title: Webbing take-up device
Inventor: ASAGIRI KATSUKI
IPC: B60R22/46
Filed: 1999-12-02
Abstract: An inexpensive webbing retractor is obtained by making a pretensioner and a lock device small and reducing the number of parts. A plurality of protrusions 126 are formed on an inner peripheral portion of the bearing body 124, which pivotally supports a clutch portion 106. These protrusions 126 are brought into linear contact with an outer peripheral portion of the clutch portion 106, whereby the bearing body pivotally supports the clutch portion 106 indirectly via the protrusions 126. Since the protrusions 126 are brought into linear contact with the clutch portion, the contact area becomes quite small. Hence, the protrusions 126 are easily plastically deformed due to friction resistance with the clutch portion 106. Therefore, resistance that obstructs the rotation of the clutch portion 106 becomes small, and gas pressure can be efficiently supplied for the rotation of a take-up shaft 20. As a result, members such as a gas generator 158 and the like which structure the pretensioner 14 can be made small, enabling reduction of cost.
