Patent CA-2488989-A1 (CA)
Title: Apparatus, and associated method, for performing packet zone timing operations at a mobile node operable in a packet radio communication system
Inventor: HSU LIANGCHI
IPC: H04L12/24
Filed: 2004-01-08
Abstract: Apparatus, and an associated method, having a packet zone list timer embodied at a mobile node operable in a packet radio communication system. The packet zone list timer provides hysteresis to reduce the possibility of a ping-pong effect when a mobile node is operated at, or crosses, a packet zone boundary.  A timer value used by the packet zone timer is selected at the mobile node without the need for network-generated commands to notify the mobile node of the timer value. Comparisons are made at the mobile node, and determinations are made at the mobile node as to whether registration of the mobile node is required.

Abstract: A method and a system for external and distributed protection of Web application data against prying, tempering, and impersonation using cryptographic mechanisms. The protection is offered opaquely so as to not expose the cryptographic mechani sm to the Web application. Protection against prying prevents users from looking at da ta the Web application considers private. When protected against prying, protect da ta may be sent to the client but the userwill not be able to understand it. Protection against tempering, guaranties the Web application that the data it is receiving originated from a trusted source, usually the Web application itself. A user session state stored client-side is a good candidate for tempering protection. Protection against impersonation ensures the Web application that the data it is receiving come s from a specific user.

Title: Method, apparatus and computer program for calculating and adjusting the perceived loudness of an audio signal
Inventor: SMITHERS MICHAEL J
IPC: G10L11/00
Filed: 2004-05-27
Abstract: One or a combination of two or more specific loudness model functions selected from a group of two or more of such functions are employed in calculating the perceptual loudness of an audio signal. The function or functions may be selected, for example, by a measure of the degree to which the audio signal is narrowband or wideband. Alternatively or with such a selection from a group of functions, a gain value G[t] is calculated, which gain, when applied to the audio signal, results in a perceived loudness substantially the same as a reference loudness. The gain calculating employs an iterative processing loop that includes the perceptual loudness calculation.

IPC: C08J3/28
Filed: 2005-11-15
Abstract: An article suitable for use as an insulating or coating material comprises a radiation-crosslinked composition comprising a polyethylene, a polypropylene and optionally an ethylene-propylene elastomer. The polyethylene component is selected from high density polyethylene (HDPE), medium density polyethylene (MDPE) and linear medium density polyethylene (LMDPE) and the polypropylene component is either a homopolymer or copolymer. The composition is predominantly based on the polyethylene component and contains the polyethylene component in an amount of at least 50 percent by weight. The article is radiation-crosslinked to a sufficient degree that it possesses thermoset properties, such that when the article is heated to a temperature above the crystalline melting point of the polypropylene homopolymer or copolymer, it is softened but does not become liquid. The article is formed by first blending the polyethylene, polypropylene and optionally the ethylene-propylene elastomer, melt processing the blend to produce an article, crosslinking the article by exposing it to radiation, and optionally heating, stretching and cooling the article to impart heat shrinkability to the article.

Title: Chromatography columns
Inventor: BIERMANS FRANCISCUS
IPC: B01J20/26
Filed: 2006-01-23
Abstract: A cluomatography column is prepared with a stationary phase comprising a deuterated poly(ethyleneglycol), or other deuterated polymer. Formation of the stationary phase can be performed using exactly the same methodoloy as used when forming a stationary phase with the equivalent non-deuterated polymer. The deuterated poly(ethyleneglycol), or other deuterated polymer. preferably has increased thermal stability as compared to non-deuterated poly(ethyleneglycol), or equivalent non-deuterated polymer. This reduces bleeding of the stationary phase during gas chromatography and allows the use of greater operating temperatures.
