Appl. No.:

09/919645

Inventors:

Sol Goldenberg - Rockaway NJ
John Liu - Parsippany NJ

Assignee:

Electronics for Imaging, Inc. - Foster City CA

International Classification:

G06K 1502

US Classification:

358 113, 358406, 714 38, 714 45, 714 46, 717124, 717125

Abstract:

A method embodiment of the invention tests revisions made to printer graphics interpreter software. A test suite of POSTSCRIPT, PCL, or other high-level printer language is input to a production version of a printers internal interpreter software. A first bit-map is generated by the interpreter that is normally used to control each pixel in the printing of a page. The same test suite is fed to a work-in-progress revision of the printers internal interpreter software. A second bit-map is generated. The first and second bit-maps are subtracted from one another. A difference bit-map is inspected. If only minor shifts of objects are noted, or if no differences at all are apparent, the work-in-progress revision is accepted as the new production standard. The second bit-map is used to replace the first. Otherwise, the work-in-progress revision of the printers internal interpreter software is reworked to correct the printing interpretation errors it was making.

International Classification:

C22C 21/10

US Classification:

148417, 420532

Abstract:

Aluminum alloy products, such as plate, forgings and extrusions, suitable for use in making aerospace structural components like integral wing spars, ribs and webs, comprises about: 6 to 10 wt. % Zn; 1. 2 to 1. 9 wt. % Mg; 1. 2 to 2. 2 wt. % Cu, with Mg≦(Cu+0. 3); and 0. 05 to 0. 4 wt. % Zr, the balance Al, incidental elements and impurities. Preferably, the alloy contains about 6. 9 to 8. 5 wt. % Zn; 1. 2 to 1. 7 wt. % Mg; 1. 3 to 2 wt. % Cu. This alloy provides improved combinations of strength and fracture toughness in thick gauges. When artificially aged per the 3-stage method of preferred embodiments, this alloy also achieves superior SCC performance, including under seacoast conditions.

Inventors:

John Yuming Liu - Fresh Meadows NY, US

International Classification:

F24H 3/00

US Classification:

237 70

Abstract:

Design the device Steam baseboard to use for steam heating. Water is not easy to get out and water creates the noise and does not easy to get out of the system. Water prevents the heating. We convert the hot water heating baseboard to steam baseboard by using the John's pipe and John's effect.

Appl. No.:

11/588153

Inventors:

John Yuming Liu - Fresh Meadows NY, US

International Classification:

F22B 1/18

US Classification:

122 7 R

Abstract:

Condenser will create a lot of heat from compressor and exhaust heat has to be removed from it. This exhaust heat can be recovered to store in the hot water tank. More important the heat generated by freezer, air conditioner and refrigerator has to be removed either store in the hot water tank or dissipated by baseboard. We design this method to accomplish this goal. We use water to dissipate the heat and we do not waste the water. Water is very expensive about $5.00 per hundred cubic feet. This method will save fuel to pre-warm the water for hot water tank.

International Classification:

B60R 27/00

US Classification:

296200

Abstract:

This invention is to replace any mechanical wind wiper for a vehicle operation. We construct the air pump to blow the air to push the debris, rain water, and snow away from the windows. The pneumatic windshield clearing system includes an air source from engine assembly or and muffler coupled with vehicle, a metal pipes with small holes to have the high pressure pushed air from the top, bottom and side of windshield toward the surface of the windshield.
