Patent CA-2396137-A1 (CA)
Inventor: HONG THOMAS K
IPC: A63B57/10
Filed: 2002-07-30
Abstract: A golf ball teeing device comprises a base member and a hopper. A golf ball delivery track is substantially straight between its proximal end and its distal end, and is mounted adjacent the proximal end on the base member for substantially vertical travel between a lowered rest position and a raised ball teeing position. A golf ball placement aperture is disposed adjacent the distal end. A support receives the golf balls in seriatim from the hopper and presents each received golf ball for subsequent delivery to the track. An actuation mechanism moves the golf ball delivery track from the lowered rest position to the raised ball teeing position and subsequently back to the lowered rest position, and permits selective delivery of the golf balls presented by the support sequentially onto the golf ball delivery track for subsequent placement on the tee.

Abstract: A cardiac harness for treating congestive heart failure is disclosed. The harness applies elastic, compressive reinforcement on the left ventricle to reduce deleterious wall tension and to resist shape change of the ventricle during the mechanical cardiac cycle. Rather than imposing a dimension beyond which the heart cannot expand, the harness provides no hard limit over the range of diastolic expansion of the ventricle. Instead, the harness follows the contour of the heart throughout diastole and continuously exerts gentle resistance to stretch. Also disclosed is a method of delivering the cardiac harness to the heart minimally invasively.

IPC: G06Q40/00
Filed: 2001-10-05
Abstract: A method and system for reducing the time it takes for a trader to place a trade when electronically trading on an exchange, thus increasing the likelihood that the trader will have orders filled at desirable prices and quantities. The "Mercury" display and trading method of the present invention ensure fast and accurate execution of trades by displaying market depth on a vertical or horizontal plane, which fluctuates logically up or down, left or right across the plane as the market prices fluctuate. This allows the trader to trade quickly and efficiently. The price consolidation feature of the present invention, as described herein, enables a trader to consolidate a number of prices in order to condense the display. Such action allows a trader to view a greater range of prices and a greater number of orders in the market at any given time. By consolidating prices, and therefore orders, a trader reduces the risk of a favorable order scrolling from the screen prior to filling a bid or ask on that order at a favorable price.

Title: High efficiency engine with variable compression ratio and charge (vcrc engine)
Inventor: COWANS KENNETH W
IPC: F02B75/02
Filed: 2001-11-29
Abstract: An internal combustion engine using variable compression ratio and variable fuel supply to one of two combustion chambers is presented. Varying the compression ratio is accomplished by changing the volume of a single combustion chamber (53) with an auxiliary piston (57) that is biased in an open position by spring (58). This, in combination with lean burning, results in a highly efficient prime mover particularly at the low torque outputs needed in passenger car applications. The relationship of compression ratio and fuel feed is varied with engine speed. Burning occurs in two stages, and this results in a clean exhaust. The invention allows very efficient throttling of two-cycle engines to be realized. A concept for supplying air to a two-cycle engine at very good efficiencies is also presented. The combination of these techniques can result in an engine for automotive use that is half the weight of conventional units with a thermal efficiency of 40 % or more at average engine output.
