Patent CA-2386410-A1 (CA)
Inventor: ALDAZ C MARCELO
IPC: C12Q1/68
Filed: 2000-10-06
Abstract: The present invention relates to a method for the detection of gene expressi on and analysis of both known and unknown genes. The invention is a highly sensitive, rapid and cost-effective means of monitoring gene expression, as well as for the analysis and quantitation of changes in gene expression for a defined set of genes and in response to a wide variety of events. It is an important feature of the present invention that no single molecular species of cDNA gives rise to more than one fragment in the colleciton of products whic h are subsequently amplified and representative of each expressed gene. This achievement is facilitated by immobilizing the cDNA prior to digesting and then digesting with sequentially with two frequently cutting enzymes. Linker  oligomers are ligated to each cut site following the respective digestion. Primers, complementary to the oligomer sequence with an additional 3' variab le sequence are used to amplify the fragments. Using and array of fragments theoritically facilitates the amplification of all of the possible messages in a given sample.

Patent CA-2393373-A1 (CA)
Inventor: GERKIS ANTHONY
IPC: H04L12/56
Filed: 2002-07-15
Abstract: A novel apparatus, system and method for transmitting data flows which have different quality of service (QoS) attributes over a network link structured in two or more channels is provided. The method classifies arriving packets to determine their required/assigned QoS attributes and places the classified packets into one of several logical channel queues, the selected logical channel queue having an appropriate corresponding set of QoS  attributes defined for it. A radio link controller examines the available channels and, for each channel, selects a logical channel queue whose contents will be transmitted thereon. The radio link controller determines the data transmission capacity for each channel and segments the contents of the selected logical channel to fit within the determined capacity. The selection of the logical channel queue is performed in accordance with the set of QoS attributes and thus each flow can have different QoS characteristics including priorities, reliabilities (ARQ, no ARQ, etc.),.

Abstract: A separating and collecting method for collecting high-purity 18F from 18O water with high efficiency and maintaining the purity of the 18O water. By using a solid electrode (1) as an anode and a container (electrodeposition bath) (2) made of platinum as a cathode, 18F in a solution (4) is electrodeposited on the solid electrode by applying a voltage. Then by using  the solid electrode (1) on which 18F is electrodeposited as a cathode and a container (collecting bath) (5) in which pure water is placed as an anode, 1 8F is collected in the pure water by applying a voltage of the opposite polarit y to that of the electrodeposition. In the process, the loss of the 18O water is little. The initial concentration of the 18O water is maintained even after the 18F electrodeposition, and therefore the 18O water can be repeatedly use d as an irradiation target for production of 18F.

Title: Method and apparatus for providing mobile and other intermittent connectivity in a computing environment
Inventor: OLSON ERIK D
IPC: H04L29/06
Filed: 2001-09-12
Abstract: A seamless solution transparently addresses the characteristics of nomadic systems, and enables existing network applications to run reliably in mobile environments. A Mobility Management Server (102) coupled to the mobile network maintains the state of each af any number of Mobile End Systems (104) and handles the complex session management required to maintain persistent connections to the network and to other peer processes. If a Mobile End System becomes unreachable, suspends, or changes network address (e.g., due to roaming from one network interconnect to another), the Mobility Management Server maintains the connection to the associated peer task- allowing the Mobile End System to maintain a continous connection even though it may temporarily lose contact with its network medium. An interface-based listener uses network point of attachment information supplied by a network interface to determine roaming conditions and to efficiently establish connection upon roaming. The Mobility Management Server can distribute lists to Mobile End Systems specifying how to contact it over disjoint networks.

Filed: 2001-09-25
Abstract: A web crawling engine (110) is configured to mine auction web sites (120) for auction market data. On-line auction market data are aggregated for use in determining how to best list an item for sale through an on-line auction. The market data include listing options (e.g., duration, opening bid) as well as data descriptive of the auction's progress (e.g., current bid). Auction market data can also be actively accumulated by actively listing items at auction, varying the listing options, and monitoring the same auctions. Data is analyzed to identify correlations between item listing options and desirable auction results, such as closing bid price. A multivariable curve fitting is performed based upon the accumulated data to create a function that yields auction revenue as a function of listing options. A set of options that corresponds to the maxima of this function is identified as an optimal set of listing options for a product.
