Patent CA-2527986-A1 (CA)
Title: High-density recording medium and recording and/or reproducing device therefor
Inventor: KIM JIN YONG
IPC: G11B7/24
Filed: 2004-06-03
Abstract: Disclosed herein are a high-density recording medium, such as a high-density optical disc and a recording and/or reproducing device therefor. At a transition area of the high-density optical disc allocated between a clamping area and an information area of the high-density optical disc is formed a step having a prescribed slope so that the high-density optical disc does not collide with an objective lens of an optical pickup provided in an optical disc device although the objective lens of the optical pickup is upwardly moved toward a recording layer of the high-density optical disc until it moves to the maximum working distance when the high-density optical disc, such as a Blu-ray disc, is improperly placed on a turntable provided in the optical disc device, e.g., when the high-density optical disc is placed upside down on the turntable. The thickness of the information area is smaller than that of the clamping area by the provision of the step at the transition area.  Consequently, damage to the high-density optical disc or the objective lens due to a collision of the objective lens with the high-density optical disc is prevented, and fatal errors of a servo operation are effectively prevented.  Furthermore, the cost of materials required to manufacture the high-density optical disc is reduced while stable clamping force is maintained, and safe insertion of the high-density optical disc into a slot-type optical disc drive is possible.

Title: Ray tracing in discontinuous multimode channel waveguides
Inventor: BIERHOFF THOMAS
IPC: G02B6/10
Filed: 2004-07-23
Abstract: The invention relates to a method for determining the transmission behaviour of an optical waveguide with a step index profile, wherein the optical waveguide is composed of guide pieces, protruding into each other, so that the surfaces of said guide pieces comprise real and virtual surfaces, lying respectively outside and inside another guide piece. The transmission behaviour is determined by geometric ray tracing, wherein the points of intersection of a ray with the surfaces of the guide pieces are determined, which are thus defined analytically, in particular, by extrusion of cross sections along an axial trajectory. A real material transition can be determined by an iterative procedure.
Patent CA-2534951-A1 (CA)
Inventor: KAEVER PETER
IPC: A01J9/04
Filed: 2004-08-13
Abstract: In order to improve the functionality of a cooling arrangement (4), the invention provides a method for providing data for a control system for a milk cooling arrangement (4), a method for cooling milk in a milk cooling arrangement, and a control system. Data, which are relevant to the cooling tank and which are at least specific to the milk at at least two milking stations, are determined for the control system of a milk cooling arrangement of a milking system and are provided to said control system. At least one characteristic quantity is determined from this data, and the milk cooling arrangement is activated when at least one characteristic quantity lies outside a tolerance zone, particularly when it exceeds a predetermined threshold value. Shorter cooling times and an improved use of resources are achieved due to the interaction of the milking parlor control with the control system of a milk cooling arrangement. In addition, the invention enables an operator to set parameters and log the operation of the milk cooling arrangement in a convenient manner.

Title: Process for restoring magnetic recording tape damaged by "sticky shed" syndrome
Inventor: RICHARDSON CHARLES A
IPC: G11B23/50
Filed: 2004-09-13
Abstract: A process for restoring magnetic recording tape damaged by "Sticky Shed"  syndrome cleans magnetic tapes (13) of the Backcoating which is causing their eventual degradation and destruction. The Backcoating is first removed in a multi-step process. A liquid cleaner, such as isopropyl alcohol, is applied to the Backcoating to dissolve it from and clean it off the Mylar Base. Before the liquid cleaner is applied, steps are taken to prevent the cleaner fluid from getting onto the Oxide side of the tape. The chemical cleaning is done as quickly as possible. The second step is to dry clean the Base surface of the tape to remove the remaining solvent and the debris of any remaining Backcoating. Then, the Oxide side of the tape is given a dry, non-chemical cleaning to remove the residue of contamination of the Backcoating which was deposited on the Oxide side of the tape as the result of physical contact with the Backcoating from the storage on the reel of tape. once fully and properly cleaned, the tape is restored to a useful and long life. A machine (10) is disclosed to carry out various mechanical and chemical actions involved in the inventive process in a safe and logical manner.

Patent CA-2540897-A1 (CA)
Title: Method and apparatus for providing authentication, authorization and accounting roaming nodes
Inventor: O'NEILL ALAN
IPC: H04L9/00
Filed: 2003-10-14
Abstract: The invention proposes an integrated process of authorizing and securing at layer 2 (L2) followed by layer 3 (L3). The L3 process treats the wireless link as any normal IP access link, and the L3 authorisation provides L3 processing, but also includes the L2 terminal authentication identifiers so that the L2 security parameters can also be returned. This means that the wireless link and the IP layer are not secured until after the L3 authorisation has completed and therefore the first IP messages that trigger authorisation are sent insecurely. This invention also provides methods to avoid these insecure messages presenting any opportunities to an attack. This inventions include methods to enable L3 before L2 authorisation when a user is roaming in a foreign network (480). These enable different types of AAA servers (450) in the foreign domain (480) to work with different types of AAA servers (460) in the home domain (470) to provide dynamic assignment of foreign mobility agents and the associated security associations between home and foreign mobility agents, as well a temporary account in the foreign domain (480). These methods apply both to standard MIP as well as Nested MIP, and to different types of Mobile Node apparatus and a range of user, host and terminal authentication models.
