Patent number: 6418387Abstract: A method of generating a plot that evinces common result regions of a test as a function of controllable input parameters includes defining an overall plot region that is a function of the maximum and a minimum of each input parameter. The method further subdivides the overall plot region into at least two sub-regions, where each of the sub-regions has a sub-region boundary. The method evaluates, for each of the sub-regions, a plurality of boundary test conditions on the sub-region boundary according to the test, so as to assign a test status to each of the plurality of boundary test conditions. For each of the sub-regions with at least a predetermined threshold number of boundary test conditions having a common test status, the method designates the sub-region with the common test status. For each of the sub-regions not having at least the predetermined threshold number of boundary test conditions with a common test status, the method designates that sub-region with an indeterminate status.Type: GrantFiled: June 28, 1999Date of Patent: July 9, 2002Assignee: LTX CorporationInventor: Michael D.

Patent number: 5063392Abstract: An improvement is provided for printer such as the dot matrix or thermal type, in which the printhead is stepped across the paper over a multicolor ribbon supplied from a pivotally mounted cartridge and transported through a plane between the line of traverse of the printhead and the surface of the paper. The ribbon is guided by guiding surfaces positioned on each side of the printhead, close to the printhead, and mounted to move with the printhead across the paper so that the guide surfaces will guide the path the ribbon takes to one which passes between the printhead and the paper with the guide being moveable in steps in a direction normal to the traverse of the printhead and parallel to the plane of the ribbon so as to position a selected color band of the ribbon under the printhead to select the color to be printed as the printhead traverses the paper.Type: GrantFiled: January 2, 1990Date of Patent: November 5, 1991Assignee: General Signal CorporationInventors: Daniel J.

Patent number: 5033889Abstract: A method for operating a dot-matrix printer to allow printing in the accelerating and decelerating regions of the carriage traverse, which comprises the steps of: firing the wires for registration at the present position of the carriage and stepping the carriage by energization of a stepper motor driving the carriage for the period required to complete the step when accelerating the carriage or the period required to brake the carriage when decelerating the carriage. These times will decrease as the carriage accelerates to the desired velocity and will increase as the carriage decelerates from the desired velocity.Type: GrantFiled: March 20, 1989Date of Patent: July 23, 1991Assignee: General Signal CorporationInventor: Michael D.
