Patent CA-2089823-A1 (CA)
Title: Dynamic signal routing
Inventor: WANG THERESA C Y
IPC: H04L12/56
Filed: 1993-02-18
Abstract: DYNAMIC  SIGNAL  ROUTING                 ABSTRACT OF THE DISCLOSURE       Data packets are delivered through a constellation of nodes to a termination unit.  The node where a packet leaves the constellation is a terminal node. Each packet includes a routing code.  When a node receives a packet, it examines the routing code to determine if that node might be the packet's terminal node.  A table look up operation is performed using the routing code as an index to a routing table.  The table identifies a link to use in routing the packet away from the node to a neighbor node.  The packet is also examined to verify compatibility between packet type and a selected link.  If an incompatibility exists, a substitute link is selected.  When a node concludes that it might be a terminal node for a packet, it evaluates a channel identifier to determine if it is currently serving the party to whom the packet is directed.

Title: Method and apparatus for sampling and detecting gases in a fluid
Inventor: TIKIJIAN GEORGE H
IPC: G01N1/22
Filed: 1994-01-24
Abstract: ABSTRACT    There is disclosed a method and apparatus for repetitively taking samples of a predetermined quantity of a test gas in a liquid and introducing these samples to a test chamber.   Each sample is agitated to release therefrom the test gas.  The released gas is then conveyed to a sensor, which monitors the released gas for the presence of a concentration above the threshold level to produce an alarm indicative thereof.  The samples of the test gas in a liquid may be repetitively taken from one zone of a plurality at a time until each zone is sampled.  After one sample has been tested in the test chamber, it is discharged therefrom and the test chamber is flushed with a sample of the liquid and test gas taken from the next zone of the plurality before introducing the next sample from the next zone.

Title: Immunoassay for quantitatively determining antigens
Inventor: IMAI SHINJIROU
IPC: G01N33/543
Filed: 1994-06-10
Abstract: ABSTRACT OF THE DISCLOSURE         An immunoassay for quantitatively determining an antigen in a sample is disclosed, which comprises immobilizing a primary antibody in a purified state or in a diluted serum to the surface of a carrier via an affinity ligand, particularly protein A, immobilizing an antigen to be determined to the primary antibody, and reacting a labeled secondary antibody with the antigen.  This method can attain a markedly improved identification limit and measurement limit which have not been attained by conventional methods, eliminates purification of the primary antibody, and enables one to save the amount of immobilized antibody.  In addition, it provides a measuring method which is inexpensive and yet effective and which can determine a trace amount of ingredient with high sensitivity.
