Patent CA-2414899-A1 (CA)
Inventor: FROMM PAUL M
IPC: G03G15/20
Filed: 2002-12-20
Abstract: In a fuser for xerographic printing, stripper fingers remove the print sheet from a fuser roll. Each stripper finger is a thin member which is urged against the fuser roll with a spring force caused by deformation of the stripper finger against the roll. Each stripper finger is mounted on a mount which is itself springably urged against a stop, so that the spring force of the stripper finger is largely independent of the spring force associated with the mount. A baffle defines a surface adjacent the first stripper finger along a length of the fuser roll when the first stripper finger is contacting the fuser roll. The baffle aids in causing a sheet crumpling between the roll and the first stripper finger mount to move the first stripper finger mount away from the roll. The arrangement enables design latitude in choosing spring forces associated with the stripper finger and the mount, and also enables the stripper fingers to be moved away from damaging contact with a mis-stripped sheet.

Patent CA-2418269-A1 (CA)
Inventor: SEDLAK HOLGER
IPC: G06F7/72
Filed: 2002-01-24
Abstract: The invention relates to a method for modular multiplication using a multiplication prediction process for calculating a multiplication shift val ue and a reduction prediction process for calculating a reduction shift value. According to said method, a modulus is first transformed (10) into a transformed modulus, which is greater than the modulus. The transformation i s carried out in such a way that a predefined portion of the transformed modul us has a higher order position with a first predefined value, which is followed  at least by a lower order position with a second predefined value. During th e iterative processing (12) of the modular multiplication using the multiplication prediction process and the reduction prediction process, the transformed modulus is used to obtain a transformed result for the modular multiplication at the end of the iteration. Finally, the transformed result undergoes an inverse transform (14) by means of modular reduction using the original modulus. The inventive transformation simplifies the iterative processing of the modular multiplication, enabling the latter to be carried out more rapidly.
