Patent CA-2189900-C (CA)
Inventor: MASSEE JOHAN
IPC: B21D22/16

Granted: 2003-01-07
Abstract: Method and apparatus for spinning a product, wherein a metal plate which may be preshaped or not, is deformed on a rotating chuck by a forming roller into a hollow product with a wall thickness. The shape of the chuck is determined and is stored in a memory of a control unit as a series of successive points. The control unit moves the forming roller according to a path corresponding with the shape of the chuck. This path is determined by the stored shape of the chuck with a desired wall thickness of the product added thereto. The metal plate is deformed by moving the forming roller according to the thus determined path. In each point of the stored shape of the chuck, the control unit determines a tangent line of the chuck shape at the location of this point and adds the desired wall thickness to the wall thickness at the location of this point accor-ding to a line perpendicular to the tangent line to calcu-late the path of the forming roller.

Abstract: A method and system for providing controlled access to information stored on a smartcard. The system includes a data processing center maintained by a trusted third party for storing a database of authorizations of various service providers to access information pertaining to individuals, and for responding to request by service providers for access from terminals which communicate with the data processing center and smartcards storing the individuals' information. The information is stored on the smartcard in encrypted form and the data processing center provides an access code, which includes a key for decrypting the information, only to service providers who are authorized to access the information. The service provider then sends the access code to the smartcard which verifies the access code and decrypts and outputs the requested information. The smartcard then computes a new key as a function of information unique to each access session and uses the new key to re-encrypt the information, and then erases the new key. The data processing center also computes the new key so that the data processing center can provide an access code including the new key for the next request for access.

Granted: 2006-03-07
Abstract: The present invention is a method of detecting reaction in blood caused by the presence of a foreign substance in the blood, comprising the steps of: establishing a potential across a predetermined spatial volume;  passing a first portion of the blood through the predetermined spatial volume; substantially continuously measuring the potential across the predetermined spatial volume over a first predetermined period of time; comparing the measured potential with a baseline; and calculating the total volume of solids in the first portion of the blood as a function of a total absolute deviation of the measured potential from the baseline. The same procedure is then followed with a second portion of the blood, after it has been exposed to the substance whose reaction is being determined. The two calculations are then compared, with a positive reaction being indicated when the two measured solid volumes are measurably different. The baselines are preferably dynamic baselines, and are determined with reference to the starting point of a sharp rise in the measured potential.

Title: Multi-channel audio enhancement system for use in recording and playback and methods for providing same
Inventor: KLAYMAN ARNOLD I
IPC: H04S5/02
Filed: 1997-10-31
Granted: 2006-04-25
Abstract: An audio enhancement system and method (10) for use receives a group of multi-channel audio signals (18) and provides a simulated surround sound environment through playback of only two output signals (26 and 28). The multi-channel audio signals (18) comprise a pair of front signals intended for playback from a forward sound stage and a pair of rear signals intended for playback from a rear sound stage. The front and rear signals are modified in pairs by a multi-channel audio immersion processor (24). The multi-channel audio immersion processor (24) separates an ambient component of each pair of signals from a direct component and processing at least some of the components with a head-related transfer function. Processing of the individual audio signal components is determined by an intended playback position of the corresponding original audio signals. The individual audio signal components are then selectively combined with the original audio signals to form two enhanced output signals L OUT and R OUT for generating a surround sound experience upon playback.
