Abstract: This invention is about the arithmetic operation circuit of all the arithmetic operations in the finite field GF(2<m>) that can be executed. The invention includes an arithmetic processor (AP), an arithmetic logic unit (ALU) and a control circuit. The arithmetic processor is constructed on the computing processor (CP) by integrating finite field GF(2<m>) multiplication (AB) and AB<2> operation (A, B are the arbitrary elements in the finite field GF(2<m>)) on a single circuit. In the finite field GF(2<m>), multiplication, division, exponentiation, and multiplicative inverse can be completed by the arithmetic processor (AP). The arithmetic logic unit (ALU) is then used to complete the addition of the finite field GF(2<m>). Having the arithmetic processor (AP), the arithmetic logic unit (ALU) and the control circuit, any arithmetic operation of the finite field GF(2<m>) can be completed by this mainframe of arithmetic unit (AP).

Title: Method of lithographic imaging with reduced debris-generated performance degradation and related constructions
Inventor: LEWIS THOMAS E
IPC: B41C1/10
Filed: 1999-03-22
Granted: 2001-01-21
Abstract: The performance-limiting effects of thermal breakdown on ablation-type lithographic printing plates are overcome by rendering the ink-accepting surface largely impervious to the effects of debris originating with the surface layer of the printing member, or by discouraging the formation of harmful debris altogether. In one approach, the ink-accepting surface is a highly crosslinked polymer. The resulting cured matrix exhibits a sufficient degree of three-dimensional bonding to resist melting, softening, or chemical degradation as a result of the imaging process. Alternatively, an intervening layer, dispoded between the imaging layer and the surface layer, prevents the surface layer from undergoing significant thermal degradation in response to imaging radiation or ablation of the underlying imaging layer, and is also formulated to produce little debris or debris having an affinity for ink and/or fountain solution similar to the affinity of the substrate -- e.g.,which does not reduce the oleophilicity of the underlying ink-accepting surface. Following imaging, the remnants of the insulating layer are removed along with the surface layer where the plate received imaging radiation.

Title: Image servo positioning and path-tracking control system
Inventor: LIN GU-CHIN
IPC: G06F17/50
Filed: 1999-03-31
Granted: 2001-05-16
Abstract: The present invention relates to an image servo positioning and path-tracking control system consisting of a computer-aided image capture and analysis subsystem and a positioning and path-tracking control subsystem. The image capture and analysis subsystem is referred to the images of the reference tracking path, the controlled point, and their surroundings captured by the image device. After the images are digitally processed through interface signals, by way of computer program analysis, the real-time pixel deviation magnitude and deviation direction between the controlled point and the reference position can be calculated for being used as a base to position and path-track the correction control. The positioning and path-tracking control subsystem is referred to the computer-controlled servo mechanism, transmission mechanism, and other related electric integration elements for positioning and path-tracking at the controlled point. In order to accomplish the purpose of servo positioning control or path tracking, the both of the two subsystems can be serially connected to a computer for the analytical calculation and correction control of positioning and path-tracking deviation at the controlled point, or each of the subsystems is serially connected to a different computer, while, by way of cable or wireless signal, the real-time pixel deviation magnitude and deviation direction can be transmitted and the two subsystems can be integrated. Typical application examples of the present invention include all those image-assisted control systems, such as path-tracking laser surgical operation, laser cutting process, line cutting, and robot arm drilling, welding, spray-painting, and grinding, that can perform positioning and path-tracking.
