Patent number: 6037041Abstract: The invention relates to a method of providing an encodable layer on a glass object and on the resultant product. The layer is formed by providing a paste containing glass frit, pigment and a binder, on the hot glass. As a result, the glass frit melts, causing the pigment to adhere to the glass object. The binder, which is used to render the paste spreadable, disappears from the mixture.Type: GrantFiled: June 19, 1997Date of Patent: March 14, 2000Assignee: U.S. Philips CorporationInventors: Raymond J.

Patent number: 6023557Abstract: A photographic printer that uses a plurality of small CRTs, or multiple image segments displayed on a single CRT, to print wide format images. Within the printer, the multiple CRTs are positioned adjacent one another and display through lenses so that image segments displayed by adjacent CRTs join one another. The image segments of the single CRT also display through lenses, or mirrors and lenses, that join the segments. The printer may decompose each line of the image into horizontal image segments, or the printer may receive each image segment from a host computer system, and the printer displays the image segments on the CRTs such that they are exposed joined with one another on the photographic media. The printer also contains a closed loop calibration system to adjust the length of each image segment.Type: GrantFiled: August 17, 1998Date of Patent: February 8, 2000Assignee: Sienna Imaging, Inc.Inventor: Kerry L.

Patent number: 5786903Abstract: The present invention discloses a multi-power control system for scanners. The method of the present invention has a mode of warm up time, which is controlled by a software that is embeded in a computer. Users can choose a mode of warm up time to control the warm up duration when a cathode ray tube needs. After scanning, users can determine whether the scanner is to operate or in standby status. When the user chooses the latter, the luminosity of the cathode ray tube is according to the user's pre-set. This multi-power control system not only can reduce the warm up time but also can be in harmony with the concept of enviromental protection.Type: GrantFiled: April 23, 1996Date of Patent: July 28, 1998Assignee: Must Systems Inc.Inventors: Tsao-Chin Gene Tai, Ming-Sung Huang

Patent number: 5239243Abstract: Disclosed is a system having a memory mapped deflection to control the position of an electron beam within a CRT used to project a color image onto a photographic medium for printing. A horizontal position counter is incremented at a linear rate, and the counter value is translated, using a translation table stored in memory, into a current used to drive the yoke of the CRT. The translation introduces non-linearities into the output voltage which results in a linear forward sweep across the CRT. A sweep direction signal is used as an address bit of the translation table, to allow an optimized retrace motion profile which results in an improved linear beam motion across the face of the CRT during the forward sweep immediately following retrace.Type: GrantFiled: October 1, 1992Date of Patent: August 24, 1993Assignee: Alliant Techsystems, Inc.,Inventors: Rick Rothe, Thomas A.

Patent number: 5084656Abstract: Disclosed is a system having a vertical position register and a horizontal deflection controller to position an electron beam within a CRT used to project an image onto a photographic medium for printing. When data is being displayed on the CRT, the beam is positioned vertically to the desired color phosphor row and then swept across the face of the CRT while the data is used to modulate the beam. During retrace, the beam is stopped at the center of the CRT and displaced vertically to a home position while waiting for the next dot row of information. The home position is located above the center of the phosphor area so that no leakage occurs if the beam remains in the home position for extended periods. Furthermore, while in the home position at the center of the CRT, the horizontal deflection amplifier dissipates a minimum amount of power.Type: GrantFiled: February 5, 1991Date of Patent: January 28, 1992Assignee: Alliant Techsystems, Inc.Inventors: Thomas A.
