Title: Breast biopsy apparatus and method of use
Inventor: LABASH STEPHEN SAMUEL
IPC: A61B19/00
Filed: 1995-08-15
Abstract: An apparatus and method for obtaining samples of suspicious breast tissue is disclosed.  The breast is placed between two plates, which compress, and therefore stabilize the tissue.  The upper compression plate has an aperture therein that allows for the placement of a guide spool having a flesh adhering surface thereon onto the compressed breast itself.  Markings on the spool allow for accurate placement using the cross hairs, or laser light pointer, of the mammographic unit.  For additional placement verification, the guide spool is radiopaque and, thus, an X-ray taken directly down through the aperture will aid in ascertaining if the spool is properly placed.  A tubular punch is advanced and rotated, cutting through the tissue, which is recovered in the tube.  Alternatively, a localizing needle can be placed with its tip proximate the calcification, a guide wire mandrel having the same diameter as the guide spool aperture placed over it, the guide spool placed and aligned, the mandrel removed, and the tubular punch is inserted and advanced as above, removing the tissue in question, along with the localizing needle.

Steps (b) and (c) are repeated several times to define a corresponding number of printing stages arranged at predetermined locations along the aforesaid path and each using a coloring agent of different color, and to thereby produce several differently colored images which are transferred at respective transfer positions onto the substrate in superimposed relation to provide the desired polychromic image.
Patent CA-2160674-A1 (CA)
Title: Apparatus and method for distorted track data recovery
Inventor: KAUFFMAN GERALD C
IPC: G11B27/00
Filed: 1994-05-23
Abstract: A helical drive system (10) reads tracks (18) on a storage medium (12), including tracks which appear as dis-torted tracks. Each track (18) com-prises a plurality of blocks of data, with each block having unique block-identifying information. A read head (16C) traverses predetermined original azimuthal paths (PO) across the stor-age medium (12) for reading the blocks recorded along each of the original az-imuthal paths (PO). A controller (50) uses the block-identifying information to determine whether any blocks ex-pected to be read during the traversal of the original azimuthal paths (P0) were not read. If expected blocks were not read, the controller (50) rewinds or oth-erwise reverses the direction of travel of the storage medium (12); sends a signal to a tape transport drive (81) to slow the speed of the medium (12); and, directs that the medium (12) be re-read at a slower tape re-read speed. During the slow re-read attempt, the read head (16C) traverses modified az-imuthal paths (P1, P2, P3,... P10) which are separated from one another by a distance less than the track pitch, thereby providing opportunities to read blocks which would not otherwise be read due to distortion of the tracks (18).

Abstract: Une source de lumière polarisée comprend une source de lumière dispersée et un élément polarisant réfléchissant placé à proximité de celle-ci. L'élément polarisant réfléchissant transmet la lumière d'une polarisation désirée et réfléchit la lumière d'une autre polarisation dans la source de lumière dispersée où elle est randomisée. Une partie de la lumière initialement réfléchie est ainsi convertie en une polarisation désirée et transmise par l'élément polarisant réfléchissant. Ce processus se répète, et les réflexions répétées ainsi que la randomisation ultérieure de lumière de la polarisation non désirée augmentent la quantité de lumière de la polarisation désirée qui est émise par la source de lumière polarisée.
