Patent CA-2253539-A1 (CA)
Title: A method for providing a secure non-reusable one-time password
Inventor: GRAWROCK DAVID
IPC: G06F1/00
Filed: 1997-04-10
Abstract: The present invention is directed toward providing a secure method to access data when the user has lost or forgotten the user password (261). In accordance with the invention and in a system where decryption of an access key (232) will give access to data, two encrypted versions of the access key are created (236, 270). A first version (236) is formed using a key (264) formed with the user password. A second version (270) is formed using a public key (266) from a public-private key pair. Generally, data access can be had by decrypting the first encrypted version (236) of the access key (232) with the password key (264).  However, if the password (261) is forgotten, access to data can be accomplished by decrypting the second encrypted version (270) of the access key (232) with the private key (280) from the public-private key pair. One embodiment of the invention requires the private key (280) to be stored at a remote site and for decryption using the private key to take place at the remote site. In this manner the user can gain access to data without significantly compromising the data security.

Patent CA-2268766-A1 (CA)
Inventor: BARABELL ARTHUR J
IPC: H04L25/49
Filed: 1997-10-15
Abstract: A system and device (200) for, and method of, detecting, characterizing, and mitigating deterministic distortion in a communication system. An exemplary communication system includes a digital adaptor (220) for sending octets on to a backbone of a PSTN, which then sends, and potentially distorts the octets, received by a line interface (130). The line interface converts the octets to baseband signals received by an analog adaptor. Several mechanisms and methods are described in which the analog and digital adaptor (220, 260) cooperate to detect the presence of distortion, in particular, robbed bit signaling, on the communication system. The characterization may then be used to mitigate the effects of the distortion. Several receive constellations are provided, each constructed in view of the transmit constellation and in view of the manner in which the deterministic distortion will distort signals transmitted over the system. The receive constellations differ from the transmit constellation.

Patent CA-2275073-A1 (CA)
Inventor: MURPHY DERMOT J
IPC: B60C23/04
Filed: 1999-06-17
Abstract: A remote tire pressure monitoring system includes a sending unit for each monitored tire, and the sending units transmit RF signals, each including an identifier ID(i) and a pressure indicator P(i). A receiver operates in a learn mode in which the receiver associates specific identifiers either with the vehicle or with specific tires. During the learn mode the vehicle is driven at a speed above a threshold speed, such as thirty miles an hour, and identifiers are associated with either the vehicle or the respective tires of the vehicle only if they persist for a selected number of signals or frames during the learning period. In one example, the tires are inflated with different pressures according to a predetermined pattern, and the pressure indicators of the receive signals are used to associate individual tire positions with the respective sending units.

Title: Vasoocclusive device including asymmetrical pluralities of fibers
Inventor: OSBORNE THOMAS A
IPC: A61B17/12
Filed: 1999-04-06
Abstract: A vasoocclusive device is adapted for introduction into a vessel of a human or veterinary patient and occluding flow through the vessel. The device includes a radiopaque member (such as a metallic coil) having a proximal end and a distal end, the distal end being introduced first into the vessel. The member is about 1.5 mm to about 3.0 mm long and no more than about 2.7 mm wide, preferably about 0.25 to 0.4 mm wide. The device also includes a distal plurality of fibers having an average distal fiber length, associated with and extending away from the distal end of the member, as well as a proximal plurality of fibers having an average proximal fiber length, associated with and extending away from the proximal end of the member.  The average proximal fiber length is about two to about five times the average distal fiber length. The average distal fiber length is preferably about 4 to 8 mm, while the average proximal fiber length is preferably about 9 to 15 mm. The distal and proximal pluralities of fibers each preferably include 8 to 10 individual fibers composed of polyester, nylon or silk of about 40 denier. The vasoocclusive device is particularly advantageous in that it can be used in vessels which are significantly narrower than those in which prior devices could be used, yet its asymmetric arrangement of the distal and proximal pluralities of fibers allows it to enjoy significantly improved lodging in such narrow vessels.
