Patent number: 4725966Abstract: A method and apparatus for modifying an image represented by digital data defining the content of one or more pluralities of cells constituting one or more color separations is described. The digital data indicates for each cell whether the respective color is "present" or "absent". The apparatus comprises scanning means (15,16) for electronically scanning along a plurality of scan lines with a mask of preselected dimensions; the respective plurality of digital data corresponding to a region including a boundary for one or more of the color separations. Programmable logic determines at each position of the mask whether the portion of the color separation within the mask includes at least one cell the content of which indicates color "present"; and modifies the digital data at another, predetermined position within the mask to change the content of the respective cell or cells of the color separation to represent color "present" or color "absent" when color "present" is detected within the mask.Type: GrantFiled: April 25, 1985Date of Patent: February 16, 1988Assignee: Crosfield Electronics LimitedInventors: Samuel E.

Patent number: 4718020Abstract: A method of operating a microcomputer for controlling a heat-reactivated dual-chamber gas adsorber ensures safe and reliable operation of the adsorber by recovering from disruption of the microcomputer execution sequence and sensing failure of the power control components which enable regeneration of the adsorbent. A non-volatile memory stores a code designating the "active-task" or subdivision of the adsorber cycle being controlled by the microcomputer. A reset circuit includes a watchdog timer responsive to disruption of the microcomputer's execution sequence. Upon reset of the microcomputer, the hardware components are set to an initial state and checked before resuming execution of the interrupted task. A purge circulation blower, for example, is turned on in the event that the heater cannot be turned off.Type: GrantFiled: May 30, 1985Date of Patent: January 5, 1988Assignee: Pall CorporationInventors: Micheal B.

Patent number: 4718024Abstract: The graphics data processing apparatus performs graphic data processing operations by combining data from two image arrays in accordance with a predetermined operation. This raster operation involves forming an image array having a pixel color code for each pixel of the combined image array formed from a combination of the color codes of corresponding pixels of the source and destination image arrays. The present invention includes a pair of data registers which define the difference in memory address between vertically adjacent pixels for the respective image arrays. This difference in memory address between vertically adjacent pixels is called the pitch and corresponds generally to the width of the display image in address space when any horizontal blanking interval is taken into account. In the present invention such raster operations can be performed on data which is stored in formats of differing pitch.Type: GrantFiled: November 5, 1985Date of Patent: January 5, 1988Assignee: Texas Instruments IncorporatedInventors: Karl Guttag, Mike Asal, Mark Novak

Patent number: 4716533Abstract: A dot pattern source image stored in a pattern memory is moved to a specified location in the pattern memory in an angle of n.times.90.degree. (n=0, 1, 2, or 3) with respect to the source image. First, area definition is made for a rectangular source area including the source image to be moved and a rectangular destination area where the source area is to be positioned after the move processing. Then, the positions of four sides of the source and destination areas are compared to determine, for each side, whether there is a processable side region which is included in the destination area but not included in the source area. When such a processable side region is found along one side, the image data in a corresponding region of the source area is moved to the processable side region with a specified angle relative to the source image data.Type: GrantFiled: April 23, 1985Date of Patent: December 29, 1987Assignee: International Business Machines CorporationInventor: Keiji Ohmori

Patent number: 4715009Abstract: A device for picking up the position of an angle of a rotating part which is provided with angle markers 11 or teeth being simultaneously distributed over its circumference, whereby at least one angle marker and/or intermediate space between two angle markers is shaped differently serving as a reference marker 12. This can be realized, for example, by a wide or smaller angle marker or gap between two angle markers. The distance between two angle marker flanks is picked up by a counter 17 which counts a cycle frequency, whereby the counter is a free running continously counting counter. The instantaneously present counter level is transmitted into a storage 18 for each angle marker flank (ascending flank or rear flank) to be evaluated. Subtractions of two successive storage values and comparisons of successive corresponding differential values are performed for recognizing a reference marker.Type: GrantFiled: November 12, 1985Date of Patent: December 22, 1987Assignee: Robert Bosch GmbHInventors: Heinz Bohmler, Rolf Daumer, Dieter Mayer, Egbert Perenthaler
