Title: Multi-supplier transaction and payment programmed processing system and approach
Inventor: HAHN-CARLSON DEAN W
IPC: G06Q40/00
Filed: 2005-12-27
Abstract: In an example embodiment, a computer-based contract-management approach processes transactions involving at least one supplier (i.e., seller or sellers) fulfilling one or more sub-components of the transaction. Each of the suppliers (e.g., as well as other transaction parties) reference the transaction when communicating transaction information such as invoices, regardless of which sub-component of the transaction the seller is involved with. The invoices are associated with the transaction using the transaction referenced in each invoice and each supplier is accordingly paid for its performance of the sub-component of the transaction with which it is involved.  From a buyer's perspective, the transaction is processed in accordance with the sub-components associated with the at least one supplier. Per each supplier, the transaction is processed generally two-dimensionally (via buyer and via suppliers), thus generally isolating (where desirable) each supplier from the sub~components of the transaction for which it is not a participant.

Title: Frequency matching and optimization system for an rf receiver
Inventor: MAURER STEVEN K
IPC: G07C9/00
Filed: 2006-02-22
Abstract: A system for selectively changing the operating frequency of an RF receiver includes a receiver having a selection interface, and a frequency matching module removably attached to the barrier operator. After detecting an input on its selection interface, the receiver responsively changes its operating frequency from its current frequency to another frequency, as determined by the input.

Patent CA-2613170-A1 (CA)
Inventor: OHLMANN HANS-ARMIN
IPC: F01L9/16
Filed: 2006-07-14
Abstract: The engine has at least one cylinder (2) each with at least one and preferably multiple air intake valves (25', 1 ) into the cylinder, and at least one exhaust port (51 ) at a lower position above the bottom position of the piston (53). A blower (4) is arranged to force air into each cylinder via each intake valve as the piston moves around the bottom position, the blower not supplying enough pressure to keep each intake valve open during upward motion of the piston, such that during upward motion of the piston, compression occurs within each cylinder, and such that during downward motion of the piston the blower forces air into each cylinder via each intake valve once each exhaust port is uncovered by the downward motion, and out of each cylinder via each exhaust port. The air intake valves are positively actuated by controlled air pressure differentials, for example by each intake valve having a valve disk (85) to close against a valve seat (1 ), a valve shaft (86), and lower and upper guide disks (87, 88). The lower and upper guide disks run in guide bores (89) and act as actuating pneumatic pistons, the guide bores extending between an air supply chamber (3) receiving air from the blower and a vacuum plenum (84). The guide disks thereby respond to a pressure differential between the vacuum plenum and the air supply chamber to actuate the valve.
