Granted: 2002-12-03
Abstract: A system and method for controlling operation of a water heater provides generating a heating demand signal which a minimum level corresponds to a required heat input for maintaining water temperature in the water tank in case of no exogenous demand for water. Responsive to the heating demand signal, air flow from the forced draft blower and flow of combustible fluid from the combustible fluid delivery system are varied to produce combustion product over a minimum 15 to 1 ratio. This allows water heating to be varied to meet maximum expected exogenous demand or to maintain water temperature with no exogenous demand.

Title: Degradable synthetic polymeric compounds
Inventor: CHAPMAN GRAHAM M
IPC: C08L29/00
Filed: 1993-12-16
Granted: 2002-03-12
Abstract: A synthetic thermoplastic polymeric compound is structurally stable during its useful life and which upon introduction into a suitable environment, degrades under chemical, photochemical and biodegradation mechanisms into innocuous products. Stabilizers may be incorporated into the thermoplastic polymer to help maintain the structural and functional integrity through the useful life of the product. Degradation is then brought about by the synergistic interaction of the biodegradable component, an oxidizable component, transition metal additives and an aromatic ketone incorporated into the thermoplastic polymer.  In the degradation process, the biodegradable component is metabolized to expose the thermoplastic polymer surface to chemical attack. In addition, the oxidizable component in conjunction with the catalytic system effects oxidative breakdown of the thermoplastic polymer to give lower molecular weight fragments that are susceptible to enzymatic attack in the decomposition environment. The result is the complete breakdown of the thermoplastic polymer into innocuous products. The chemical, photochemical, and biodegradation mechanisms comprising the degradation process occur both sequentially and simultaneously in cooperative, synergistic action to bring about the desired result.

Patent CA-2156610-C (CA)
Inventor: RABIN MICHAEL D
IPC: G10L15/06
Filed: 1994-12-28
Granted: 2000-10-24
Abstract: A voice command control and verification system and method stores for each authorized user, one or a series of speech models of voice commands or phrases uttered by the authorized user. Each speech model has an associated action component which specifies the specific action that the authorized user desires in response to the issuance of the corresponding voice command. Each user has a means of asserting his or her claimed identity to the system, preferably without an overt action such as the entry of digits. When an identity is asserted (501), and a voice command is thereafter spoken by a person, the system first matches a model of the voice command against the stored models for the user having the claimed identity (509). If there is a match, so that the voice command can by uniquely interpreted as corresponding to its associated action component, the system then verifies the claimed identity of the user by comparing the vocal characteristics contained in the same command with the vocal characteristics of the stored mode. Upon successful verification (513), the command is executed in accordance with the associated action component (515). The user of the system has thus issued only a single command to both operate the system and to verify his or her identity.

Title: Service provision system for communications networks
Inventor: BUSUIOC MARIUS-NICOLAE
IPC: H04M15/00
Filed: 1995-04-28
Granted: 2003-04-22
Abstract: A services management sys-tem, which can provide services to a mobile user, can do so via a com-bination of network platforms (10). The system uses "Co-operating In-telligent Software Agent" technol-ogy in a heterogeneous agent archi-tecture (25) to provide enough flex-ibility to deal with changing net-work constraints, for instance as the user moves. In an example, a fixed broadband network might be used in combination with radio transmitters of a mobile network. The agent architecture (25), in-volving autonomous agents work-ing co-operatively, forms a layered system using the underlying fixed network (1) for inter-agent commu-nication. In an application, a mo-bile user might move from a cell of the mobile network which can provide relatively wide bandwidth to one which can only provide lim-ited bandwidth. The service man-agement system can advise the user what services are available in ei-ther cell, at what price, based on current bandwidth usage at the two locations. If the user was already using a service which became unavailable in the new cell, the system will advise the user and, if appropriate, put the service effectively on hold until the user enters a cell in which the service is available once more.
