Title: Hvac system with powered subcooler
Inventor: KOPKO WILLIAM L
IPC: F25B7/00
Filed: 2006-03-14
Abstract: An HVAC system having a main circuit (100) and a subcooler circuit (210). The main circuit includes a main circuit evaporator (140), a main circuit expansion device (126), a main circuit condenser (118, 120) and a main circuit compressor (110, 112) connected in a closed refrigerant loop. The subcooler circuit (210) includes a subcooler evaporator (222), a subcooler expansion device (256), a subcooler condenser (260) and a subcooler compressor (250) connected in a closed refrigerant loop. The subcooler evaporator is arranged and disposed to exchange heat between liquid refrigerant in the main circuit and the refrigerant in the subcooler circuit to cool the liquid refrigerant in the main circuit prior to entering the main circuit evaporator. The operation of the subcooler circuit provides an increased cooling capacity per unit of a mass flow of cooling fluid through the main circuit condenser and subcooler condenser for the HVAC system with a predetermined design efficiency.

Title: Flexible determination of progressive awards
Inventor: MICHAELSON RICHARD
IPC: G07F17/32
Filed: 2006-02-03
Abstract: The present invention provides novel method and devices for implementing progressive systems on networked gaming machines and associated network devices. Some preferred implementations of the invention allow a target progressive pool size to be selected and apply payouts such that the actual progressive pool size is not likely to exceed greatly the target progressive pool size. Some such implementations control the actual progressive pool size by applying a function to control percentages of the current progressive pool size payable to players of a wagering game on the networked gaming machines.  The function may be a function of a current progressive pool size, target progressive pool size and bet size. The function may cause relatively higher percentages of the current progressive pool size to be payable to players when the current progressive pool amount is greater than a target progressive pool size and relatively lower percentages of the current progressive pool size to be payable to players when the current progressive pool size is less than or equal to a target progressive pool size.

IPC: A61F2/01
Filed: 2000-11-15
Abstract: A filter system for temporary placement of a filter in an artery or vein is disclosed. The filter system includes a guidewire that is first positioned across a lesion within a vessel. The guidewire may include a distal stop. A slideable filter is then advanced along the guidewire using an advancing mechanism, typically an elongate member slideable over the guidewire and contacting the filter. A capture sheath may be disposed about the filter during advancement. Once the filter is positioned downstream of the lesion, the capture sheath is withdrawn, allowing the filter to expand. Further distal advancement of the filter is prohibited by the stop.  After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.

Inventor: ENGLISH CHAD
IPC: G01B11/24
Filed: 2006-08-09
Abstract: An apparatus for measuring the coordinates of a point on the surface of an object comprises a projection system for projecting a beam of energy onto the surface of the object, a receiving system for receiving reflected beam energy from the target surface, and a detector for detecting the received energy. The projection system comprises a beam expander for expanding the width of the beam, and a focussing device for focussing the projected beam. The position of the reflected beam energy at the detector provides a measure of the range of the point on the target surface using triangulation and the direction of the projected beam provides the x and y coordinates. The focussing device can be controlled to vary the focal length of the projected beam and to control the beam size at the target object to vary the area of the target surface illuminated by the beam and thereby to control the resolution of the measurements.
