Patent CA-2422682-A1 (CA)
Inventor: CUSTODIO GABRIEL T
IPC: G06F9/44
Filed: 2003-03-19
Abstract: A software building and deployment system and related method are presented that automates interactions with a source code repository system, an external builder, and a content deployment system. All interactions with these components are under the control of a manifest, and are recorded in a central database. This database maintains a link between source code in the repositories and the code and content actual deployed in an environment, such as a testing environment or a production environment. Each manifest is assigned a release number to allow the database to track every change to an environment as separate release. This in turn allows the database to track the entire contents of an environment over time, down to the exact version of a component found in a particular release of the environment. The present invention uses this information to perform environment rollbacks to a prior release. Finally, the present invention creates a CRC value for every file that is deployed to an environment, which allows the system to determine whether any changes have been made to a deployed file during deployment or since the last deployment.

Title: An electrosurgical system
Inventor: GOBLE COLIN CHARLES OWEN
IPC: A61B18/12
Filed: 2001-10-29
Abstract: An electrosurgical system has an electrosurgical generator and a bipolar electrosurgical instrument, the generator being arranged to perform a treatment cycle in which radio frequency energy is delivered to the instrument as an amplitude-modulated radio frequency power signal in the form of a succession of pulses characterised by periods of at least 100 milliseconds between successive pulses and by a predetermined pulse mark-to-space ratio.  Energy delivery between pulses is substantially zero and the mark-to-space ratio is typically 1:4 or less. Each burst is of sufficiently high power to form vapour bubbles within tissue being treated and the time between successive pulses is sufficiently long to permit condensation of the vapour.  The treatment cycles may each include an initial period and a subsequent period, the pulse duty cycle being increased or energy delivered continuously in the subsequent period in order that tissue coagulation can be achieved quickly despite increasing tissue impedance.

Inventor: CONSTANT MICHAEL J
IPC: A61K9/00
Filed: 2002-02-28
Abstract: Hydrogels that expand volumetrically in response to a change in their environment (e.g., a change in pH or temperature) and their methods of manufacture and use. Generally, the hydrogels are prepared by forming a liqu id reaction mixture that contains a) monomer(s) and/or polymer(s) at least portion(s) of which are sensitive to environmental changes (e.g., changes in pH or temperature), b) a crosslinker and c) a polymerization initiator. If desired, a porosigen may be incorporated into the liquid reaction mixture to create pores. After the hydrogel is formed, the porosigen is removed to crea te pores in the hydrogel. The hydrogel may also be treated to cause it to assum e a non-expanded volume in which it remains until a change in its environment causes it to expand. These hydrogels may be prepared in many forms including pellets, filaments, and particles. Biomedical uses of these hydrogels includ e applications wherein the hydrogel is implanted in the body of a patient and an environmental condition at the implantation site causes the hydrogel to expa nd it situ.

Title: Temperature-controlled induction heating of polymeric materials
Inventor: STARK PHILLIP
IPC: B29C65/00
Filed: 2001-05-01
Abstract: The present invention provides new polymer induction bonding technology.  Induction heating technologies are utilized to weld, forge, bond or set polymer materials. The invention provides controlled-temperature induction heating of polymeric materials by mixing ferromagnetic particles in the polymer to be heated. Temperature control is obtained by selecting ferromagnetic particles with a specific Curie temperature. The ferromagnetic particles (13,83) will heat up in an induction field, through hysteresis losses, until they reach their Curie temperature. At that point, heat generation through hysteresis loss ceases. This invention is applicable to bonding thermoplastic materials, wherein only the area to be heated has ferromagnetic particles in it; bonding of thermoset composites (17), which have been processed with a layer of thermoplastic material (19) on one side;  curing of thermoset adhesives or composite resins; or consolidating thermoplastic composites.

Patent CA-2448214-A1 (CA)
Inventor: SHAHEEN KAMEL M
IPC: H04L12/56
Filed: 2002-05-22
Abstract: The present invention addresses the possibility of a race condition that arises due to lack of a communication mechanism between the UE (31) and the GGSN (34), saving unnecessary consumption of radio resources and reducing chances of collisions within the network. Also, the invention prevents the possibility that neither the UE (31) nor GGSN (34) respond appropriately to the Resource Reservation Protocol (RSVP) requirements by halting transmission of any RSVP path/refreshment messages to the IP network in order to refresh/maintain the reservation states due lack of clear assignment of responsability. This lack of clear understanding between the UE (31) and the GGSN (34) may result in the expiration of the IP network resource reservations made earlier for media streams. This scenario can occur with a higher probability in the absence of this dialog.
