Patent CA-2397235-A1 (CA)
Inventor: DOANY ZIYAD H
IPC: G06K7/00
Filed: 2000-06-01
Abstract: A method for simultaneously reading a serial number and/or other information from multiple colliding RF signals from RF identification tags (1-5) requires minimal additional logic in the tag's processor and provides for a powerful and rapid sorting and identification scheme. This technique employs a primary communication channel and multiple secondary channels. A  locator or reader unit (6) interrogates the tags (1-5), which respond with an RF signal. Upon receiving multiple signals, the locator or reader unit (6) commands the RFID tags (1-5) and requires them to transmit another response, which is transmitted in one of the secondary channels based on a portion of their unique serial identification number, thereby forcing the tags (1-5) to sort in the secondary channels. These secondary channels are assigned using a portion of the unique serial identification numbers for the tags.  The reader (6) then detects an acknowledgment in the occupied secondary channels and commands a tag (1-5) in a particular channel to move to the primary channel. Once the signal is transmitted in the primary channel, the reader (6) reads the identification number.  If there is further collison, the collided tags are returned to the secondary channel and sorted again using a different portion of their ID number. This process continues until all the tags (1-5) are sorted and identified. Once the tags (1-5) are all sorted, the tags (1-5) are assigned yet another channel distinct from the secondary channels that are used for sorting.

Title: Method and system for mobile communications
Inventor: HAGIWARA JUNICHIRO
IPC: H04W72/04
Filed: 1998-04-24
Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover. Additionally, when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously, the mobile station uses the same branch structure and the same communication frequency band for all of calls. Additionally, when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously, a branch structure and a communication frequency band, which can continue all of the calls, are selected and used. Therefore, the mobile communications system is suitable for transmission of various sorts of data in accordance with the development of multimedia.

Patent CA-2455196-A1 (CA)
Inventor: GINGERICH DENNIS S
IPC: F28F1/40
Filed: 2004-01-28
Abstract: The invention provides a novel means for producing helicoid flights from thin section flat aluminum sheet. Using a plurality of said flights forms a heat exchange element. The aluminum sheet is first bent longitudinally 90% to form an "L". A helicoid is formed by forging tapered ribs into the long section of the "L" shape, having no height to the rib at the bent corner and maximum rib height at the edge. Flattening the ribs at a point from the edge equal to the length of the short section of the "L", and bending the aluminum from that point at 90% will form a "U" shape. A plurality of said helicoid flights are then wound around a central insulated axis in an over lapping manner and clamped inside an insulated tube to form the heat exchange element. The counter flowing fluids passing through the pathways formed by the helicoids are collected by manifolds, at their respective ends of the heat exchanger element, and directed away as required.
