Patent CA-2442148-A1 (CA)
Title: Fire and explosion suppression
Inventor: DUNSTER ROBERT GEORGE
IPC: A62C4/02
Filed: 2002-03-28
Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) or other water mist generating means at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). Separation of the mist production from the actual discharge of the mist, and the entraining and transporting of the mist between these two stages at high pressure and high velocity, produces an output mist of very small droplet size which is carried by the entraining and transporting high pressure gas into the area to be protected, enabling a total flooding capability.

Title: Multiple-stage system and method for processing encoded messages
Inventor: BROWN MICHAEL K
IPC: G06Q10/10
Filed: 2002-10-24
Abstract: System and methods for processing encoded messages at a message receiver are described. Encoded message processing is performed in multiple stages. In a first stage, a new received message is at least partially decoded by performing any decoding operations that require no user input and a resulting context object is stored in memory, before a user is notified that the new message has been received. When the user accesses the new message, any further required decoding operations are performed on the stored context object in a second stage of processing. The message can subsequently be displayed or otherwise processed relatively quickly, without repeating the first stage decoding operations. Decoding operations may include signature verification, decryption, other types of decoding, or some combination thereof.
