Patent CA-2295480-A1 (CA)
Inventor: WESHLER ZEEV
IPC: A61N5/10
Filed: 1998-07-06
Abstract: This invention is a method and apparatus for dynamic stereotactic radiotreatment and prevention of restenosis. A stent is implanted in a coronary artery following percutaneous trans-luminal coronary angio-plasty.  Subsequent restenosis is minimized by external irradiation of the stent by ionizing radiation (40) such as gamma rays (42). The fact that the stent is significantly more opaque to x-rays than the surrounding tissue is exploited to track the stent using fluoroscopy, so that the ionizing radiation (40) can be aimed accurately at the stent. Preferably the fluoroscopic imaging (22), and the irradiation of the stent are synchronized with the patient's cardiac cycle. The external irradiation (40) may be performed hours or days after implanting the stent for prevention of restenosis, or weeks, or months after implanting the stent for treatment of restenosis, and may be fractionated.

Title: Mobile terminal based tariff acquisition system for wireless services
Inventor: RAHMAN TARIQ
IPC: H04Q3/00
Filed: 1998-08-21
Abstract: A method of acquiring potential tariff charges assessed by wireless service providers to a mobile subscriber prior to registration is disclosed herein.  The method includes transmitting a request for tariff information by the mobile terminal over a control channel to a candidate service provider. The candidate service provider determines an applicable tariff charge based on various factors such as roaming status, compulsory fees etc. The ensuing tariff charge is then transmitted back to the mobile terminal via the control channel. Subsequent tariff inquiries are made to other potential candidate service providers accessible by the mobile terminal. Once tariff information from all candidate service providers has been received, the mobile terminal may initiate registration e.g. with the cheapest service provider. The tariff information is able to be obtained prior to registering with a service provider, thus costs associated with registration are eliminated.

Patent CA-2307157-A1 (CA)
Inventor: BLEICHENBACHER DANIEL
IPC: H04N7/167
Filed: 2000-04-28
Abstract: A system for restricting access to transmitted programming content is disclosed, which transmits a program identifier with the encrypted programming content. A set-top terminal or similar mechanism restricts access to the transmitted multimedia information using stored decryption keys. The set-top terminal receives entitlement information periodically from the head-end, corresponding to one or more packages of programs that the customer is entitled to for a given period. Each program is encrypted by the head-end server prior to transmission, using a program key, K P, which may be unique to the program. The set-top terminal uses the received program identifier, p, together with the stored entitlement information, to derive the decryption key necessary to decrypt the program. Each of the k-bit program keys, K P, used to encrypt transmitted programs is obtained by applying one or more pseudo-random hash functions, H, such as a length-doubling hash function, H, to a master key, m. The illustrative hash function, H, takes a k-bit binary value and produces a binary value having a length of 2k, with H o being the left half of the output of the hash function, and H1 being the right half of the output of the hash function. A program key, K P, is obtained by recursively applying a hash function, H o or H1, to the master key, m, depending on the corresponding binary value of each bit position of the program identifier, p. The hash operation is represented in terms of an n-level binary tree, T, referred to as the key tree, with the master key, m, placed at the root of the tree. The tree is generated by applying the hash functions H o and H, to each node, until the desired number of tree levels (n) have been created. The program keys, K P, correspond to the leaf nodes at the bottom level of the tree. The program identifier, p, associated with each program key, K P, corresponds to the path through the key tree from the root to the desired leaf node.

Abstract: A belt tensioner for a motor vehicle engine comprises a pivot shaft (28) and an eccentric pivoted structure (50) mounted for pivoted movement on the pivot shaft. The belt tensioner has a rotatable pulley member (90) mounted for rotation on the eccentric pivoted structure.  A spring (64) is constructed and arranged to bias the eccentric pivoted structure in a direction tending to force the rotatable pulley member into tensioning engagement with a belt (16) trained about the pulley member. A  mounting bolt (14) is constructed and arranged to mount the belt tensioner on the motor vehicle engine (12), said pivot shaft being movable relative to said mounting bolt and towards said belt during a belt tensioner installation procedure. The present invention also relates to a method of installing a belt tensioner in which the pivot shaft moves in a substantially exactly linear fashion as the tensioner is moved into tensioning engagement with the belt. In a preferred embodiment, when the belt tensioner is moved into tensioning engagement with the belt, an external force is applied to the tensioner to balance any belt load forces tending to tilt the tensioner during installation. The present invention also discloses a tensioner that has contact portions that oppose the tilting force applied by the belt during installation, and a portion that extends beyond the contact portions to facilitate installation.
