Patent CA-2300495-C (CA)
Title: Technique for multi-rate coding of a signal containing information
Inventor: KROON PETER
IPC: H04N7/26
Filed: 2000-03-13
Granted: 2005-01-11
Abstract: In a communications system, multi-rate coding in accordance with the invention is implemented to generate multiple representations of an audio signal at different rates. These representations contain equivalent and/or various amounts of audio information. In an illustrative embodiment, at least one of the representations is a core representation containing core audio information. The remaining representations are enhancement representations containing enhancement audio information. The core representation is necessary for recovering the audio signal with minimal acceptable quality. Such quality is enhanced when the core representation, together with one or more of the enhancement representations, is used to recover the audio signal.

Pour construire les modules et les canaux, on réunit les panneaux avant et arrière d'une buse de ventilateur moulée par soufflage et on les met en contact l'un avec l'autre de façon à définir entre eux les canaux et les modules. En général, la buse comporte plusieurs chambres de ce type pouvant être destiné notamment au liquide de refroidissement ou au fluide de direction assistée. En outre, la buse de ventilation peut servir au stockage d'autres fluides qui ne sont pas nécessairement pressurisés tels que le fluide de lave-glace.

Filed: 2001-03-23
Granted: 2003-12-16
Abstract: A new oral polymeric controlled release formulation suitable for the once-a- day administration of valproate compounds, such as divalproex sodium, has been discovered. This formulation exhibits significant advantages over the sustained release valproate formulations of the prior art. This formulation minimizes the variation between peak and trough plasma levels of valproate over a 24 hour dosing period. This formulation follows a zero-order release pattern thus producing essentially flat plasma levels of valproate, once steady-state levels have been achieved. This results in a significantly lower incidence of side effects for patients consuming such a formulation.

Title: External flue heat exchangers
Inventor: FERRARO JOSEPH C
IPC: F24D12/02
Filed: 2002-01-11
Granted: 2010-10-19
Abstract: A heat exchanger is mounted external to a section of flue pipe or is an integral part of a section of flue pipe. The heat exchanger preheats a domestic hot water supply and boosts the return water temperature,prior to reentry to the furnace coil. The heat exchanger reduces fuel use, pollution and wear of the furnace and burner. A typical heat exchanger installation includes an oil or gas burner located on a furnace or boiler having a flue pipe leading to a gaseous outlet, such as a masonry chimney. A short vertical flue section leads to a draft-regulating damper. The flue heat exchanger may be a coil of tubing wrapped around flue section, such that the tubing picks up heat from the heated flue gasses. Preheated water exits from the heat exchanger.

Abstract: A method of and system (10) for authorizing purchases made over a computer network is provided. In accordance with the present invention, a consumer (12) electronically transmits an ATM card number over the network (24) to an on-line merchant (16) from which the consumer desires to make a purchase. The on-line merchant (16) then electronically forwards the ATM card number to a third party contractor (20), such as a bank, that will oversee and authorize the transaction. The third party contractor (20) subsequently determines an authentication token type associated with the card and electronically prompts the consumer for the appropriate type of authentication token, such as a PIN  or biometric signature or the like. The consumer (12) then inputs and electronically transmits the authentication token over the network to the third party contractor (20), bypassing the on-line merchant (16). Having both the ATM card number and the authentication token, the third party contractor (20) verifies that the ATM card number and authentication token are valid, checks for sufficiency of funds, and either authorizes or denies the transaction. The authorization or denial is communicated to the on-line merchant (16) over the network, who either completes or rejects the purchase.
