The VPS (10) includes hubs (16-20) storing client data and connecting clients (22) to vendors (24) to mediate secure electronic transactions. Date may be pre-registered by banks (30) and other owners, controllers, and issuers of payment systems (32). Owners of payment systems, such as corporate/purchase cards, may authorize usage by third parties within specified limits, thus enabling them to monitor and control delegated authority. A central account authority (12) provides registration services indicating which hub services which client. The VPS (10) implements a dual key transaction system, in which verified instructions must come separately and completely independently from both client (22) and vendor (24) before transaction completion via methods accepted by both parties.  The VPS (10) allows the client (22), the vendor (24), and associated payment methods and systems (30-32) to be known, with fixed quantities and pre-registered within an authorization manager. The client (22) and vendor (24) may choose the payment method and currency used at each end of any transaction, and payment is always made within a closed system without either party having access to or knowing the details of the other's payment system. Real-time audit trails for all parties concerned are implemented, in which client (22), vendors (24), and banks (30) may trace transactions, generate reports, and initiate refunds for such secure transactions. The VPS (10) is also software and/or hardware independent, implemented by any known networking configuration for any known electronic or digital transaction, using mobile phones (28), palm-tops and digital television for purchases and credit/debit payment arrangements for any form of commerce using electronic transactions.

Patent CA-2339152-A1 (CA)
Inventor: SHINOHARA TOSHIAKI
IPC: H04N1/387
Filed: 1999-07-30
Abstract: According to the present invention, it is designed in such manner that a designation minimum unit for designating a position of an effective region of an image transmitted from a camera and a designation minimum unit for designating a size of the effective region are set independently from each other so that a restriction on one of them is not extended or applied to the other. Apart from designation minimum units (C, D) for determining the extent of an image region to be transmitted (effective region), designation minimum units (I, J) for determining position of the effective region are set to values irrelevant to the designation minimum units for determining the extent of the effective region. As a result, even when there is a restriction on the setting of one of the designation minimum units, i.e. either the designation minimum unit for designating the position of the effective region or the designation minimum unit for designating the size of the effective region, it can be set in such manner that the restriction applied to one of them is not extended or applied to the other.

Title: Memory rewriting system for vehicle controller
Inventor: YASHIKI TETSUYA
IPC: G06F21/14
Filed: 2001-03-07
Abstract: A memory rewriting system for a vehicle controller is provided. The system comprises a vehicle controller and an external rewriting device. A vehicle controller comprises a rewritable memory storing first security data. The first security data is used to determine whether rewriting to the rewritable memory is permitted. The rewriting device transfers new security data to the vehicle controller. The vehicle controller deletes the first security data and writes the new security data into the rewritable memory. Rewriting the new security data is performed by a program stored in a non-rewritable memory. Thus, the security data that is used to determine whether rewriting to the rewritable memory is permitted is rewritten with the new security data. Therefore, if the existing security data stored in the vehicle controller is invalidated, the security feature of the vehicle can be recovered. The vehicle may includes an anti-theft system. In this case, rewriting to the rewritable memory is permitted if the anti-theft system permits an operation as to the vehicle .

Title: Apparatus and method for providing guaranteed frame rate service in atm switch
Inventor: JOO SANG-WAN
IPC: H04L12/56
Filed: 2000-10-25
Abstract: A guaranteed frame rate (GFR) service providing apparatus and method for an ATM switch is provided. A cell conformance portion applies a test to each cell in an input frame with respect to generic cell rate algorithm (GCRA), cell loss priority (CLP) bit, and maximum frame size (MFS), sets the conforming bit (CB) of each cell in the frame to a conforming value if all cells of the frame pass the test, and sets the CB of each cell in the frame to a non-conforming value if at least one cell of the frame does not pass the test. A buffer management portion allocates cells with CBs set to a conforming value to a high priority queue, allocates cells with CBs set to a non-conforming value to a low priority queue, transmits the cells allocated to the high priority queue with a minimum cell rate (MCR) guaranteed, and transmits the cells allocated to the low priority queue at a cell rate allowed by a bandwidth available in a network.
Patent CA-2356488-A1 (CA)
Inventor: DOUGLAS KENNETH WADE
IPC: B65D21/08
Filed: 2001-08-10
Abstract: A sealed container for holding and storing a variety of material. The container will comprise of three different sections that will universally thread together to form a sealed container, more commonly known as a jar.      The container will consist of a bottom threaded section similar to a small jar, a middle section with internal threads on the bottom and exterior threading at the top, and a top section or lid that will thread onto the middle section.      All three sections threaded together to form a sealed container more commonly known as a jar.      The novelty of my idea is to have a container that can be separated at the half way point to allow consumers easier access to the contents at the bottom of the container. A jar of peanut butter for example, it is difficult to reach the peanut butter at the bottom of the jar. Doing so results in peanut butter over the hand and forearm. With a lid that will universally fit the top threads and the middle threads it would be an advantage to remove the entire middle portion of the jar to more easily reach the contents in the bottom. With the lid able to thread onto the bottom portion, the middle section could be cleaned and later threaded onto the bottom portion to form a larger sealed container once again.

Title: Efficient solid-state light emitting device with excited phosphors for producing a visible light output
Inventor: YANG WEI
IPC: H01L33/50
Filed: 1999-11-30
Abstract: A more efficient solid-state light emitting device in which phosphors excite d by radiation produce visible light. The efficiency is incresed by, for example, providing a reflector adjacent to the phosphor layer for reflecting  at least some of the radiation that passes through the phosphor, back into t he phosphor. The reflector may also reflect at least some of the visible light that is emitted by the phosphor toward a designated light output. Alternatively, or in addition to, the lateral edges of the active region of the radiation source can be at least partially surrounded by a visible light  emitting phosphor and a reflector. This allows more of the radiation to interact, and thus excite, the phosphor material, making the device more efficient. The reflector also may reduce optical and radiation cross talk between adjacent light emitting devices.
