Patent CA-2104228-A1 (CA)
Title: Display system and method for context-based scrolling
Inventor: KNOWLTON KENNETH C
IPC: G06F40/00
Filed: 1991-03-12
Abstract: A computer-based system for displaying all, or at least many pages of, a document, and including means for scrolling through the document for purposes such as browsing or editing. Most of the display shows text in a "greeked" form with one line of pixels representing one line of text. The greeked form, although illegible, shows shapes of text in the document by indicating the presence or absence of text. Two windows of legible text appear as if two bar-type magnifying glasses were placed over the illegible greeked text. A window may be moved to a new location by touching a stylus to a digitizing tablet (or by clicking a mouse) or by dragging with the stylus (or mouse). When the two windows are adjacent, they become latched and can be moved as one large window. Words of special significance (e.g., embedded labels or search results) can be displayed as legible tags wherever they appear, in the greeked text as well as in the legible text. The greeking is arranged to produce a checkerboard of pixels, that appears as gray, permitting black tags to stand out clearly. Because the tags appear throughout the display at locations corresponding to their locations in the document, they can add significantly to the context presented by the greeking, permitting the user to become oriented and to locate desired portions of the displayed document. Further, tags can permit a user to quickly ascertain the locations and significance of search results.

Title: Multiple powder delivery for selective laser sintering
Inventor: FORDERHASE PAUL F
IPC: B29C67/00
Filed: 1992-11-05
Abstract: An apparatus and method for producing parts by fusing selected portions of a powder layer at a target area, including the systems for delivering the powder to the target area. Multiple powder pistons (20) are included in the apparatus, each lifts a volume of powder above a surface (22) in an alternating manner relative to one another.

Patent CA-2134547-A1 (CA)
Title: Catheterization System
Inventor: LEWIS JEFFREY P
IPC: A61M25/00
Filed: 1993-06-17
Abstract: This invention relates to an improved arterial catheterization system which is designed to allow the user to quickly visualize the early flashback of blood after penetration of a vessel. The improved arterial catheterization system of this invention allows for minimum blood loss during initial penetration of the blood vessel. Specifically, this invention is directed to a system for introducing an over-the-needle catheter into a blood vessel, and comprises an inserter unit having a hollow needle and a catheter having a lumen such that the catheter is adapted to be carried on the needle. The catheter and needle cooperate to form a first flashback chamber therebetween. The first flashback chamber is at least partially translucent and allows for the visualization of blood flow upon insertion of the needle into a blood vessel. A guide wire, which is slidably mounted on the inserter unit within the needle, is dimensioned in relation to the needle in order to provide a blood flow passage therebetween. A second flashback chamber is formed in the inserter unit and connected to the needle to receive blood flow. The guide wire serves as a guide for the catheter as the catheter is advanced off of the needle, along the guide wire and into the blood vessel. The guide wire and the catheter are separable after the catheter is placed in the blood vessel.
