Title: Method for image processing to facilitate copy protection
Inventor: LEIGHTON F THOMSON
IPC: G06T1/00
Filed: 1999-07-19
Abstract: A method for mapping a work (e.g., a picture, a document or the like) comprising a large number of bytes into a relatively small bit string to facilitate copy protection. The technique creates a first string from the work with the property that if one modifies the work by some given degree (e.g., through intentional variation or perhaps merely through aging), a second string (generated by the inventive technique) and associated with the modified work is not meaningfully distinct from the first string. When applied through the algorithm, works that are similar result in the same or similar strings. As a result, an owner of the content sought to be protected may apply the algorithm to copies of the work for copy protection purposes.

Patent CA-2308707-A1 (CA)
Inventor: CHAPMAN DAVID C
IPC: G06F17/50
Filed: 1998-10-28
Abstract: An approach for representing polygons in an integrated circuit (IC) layout is provided. Polygons are represented by one or more wires, which in turn are each represented by one or more wire segments. Each wire segment is represented by a pair of directed line segments. A data structure hierarchy includes polygon data, wire data, wire segment data and branch data. The polygon data represents a set of IC devices to be represented in the IC layout. The wire data represents the wires that represent the polygons and specifies the associated wire segments and associated polygons. The wire segment data represents the wire segments and specifies the associated directed line segments for each wire segment that represent the wires and references the wire data. The branch data specifies connections between wires by specifying the connecting wire segments in the wires. A spacing check between a first polygon and a second polygon involves determining the canonical direction from the first polygon to the second polygon and testing the two closest faces between the polygons. To satisfy a spacing violation, an exclusion zone is constructed around the first polygon and the second polygon is moved a distance outside the exclusion zone which causes the minimum spacing required by a set of predetermined spacing criteria to be satisfied.

Title: Apparatus for emplacing a fastening element into a placement base, and use of the apparatus
Inventor: WEIHRAUCH ACHIM
IPC: B25C1/18
Filed: 1998-11-23
Abstract: The invention relates to a device for driving fastening elements into a base for the purpose of fastening structural components. Said device has a working piston whose range of acceleration and deceleration can be adapted to different conditions whilst maintaining an optimal driving depth (31) and minimal piston length (32). This applies to mechanical, pyrothechnicai, pneumatic, electromagnetic and electrothermal working piston drive mechanisms. These devices can be configured for manual use or for production robots, and are characterised mainly in that the working stroke is limited by a piston sleeve (35) which is connected to the piston plate (11), a land (39) which is connected to a ring element (38) or a combination of the two. A chamber is therefore formed on the piston plate side (48a) and the ring side (48b). Said chamber accommodates an e.g. mechanical return device (8) which is subjected to its own load only during the driving-in and gauging processes. The remaining piston energy is cushioned by a buffer (30). The modular configuration of the piston plate (11) and the piston shaft (10) means that the components can be optimised independently in terms of shape and material. The piston mass can be varied considerably. The device can be configured with any degree of rigidity and can be adapted to different fastening elements, bases and driving-in conditions.
