Title: Spray dried tannin/spray dried phenolic dry mixtures to produce osb binders
Inventor: GRES EDWARD M
IPC: C09J161/06
Filed: 2000-10-27
Abstract: A method of preparing OSB (oriented strand board) binders consisting of modified tannins in solid particulate form and dry blended in a specific manner with spray dried phenolic resole adhesives, the hybrid polymer mix made without the inclusion of any additional formaldehyde 'donors' normally used with the tannin binders. The novel dry mix of specific ratios of dry tannin/phenolic powders when applied to OSB wood wafers and strands in the OSB mill blender allows the mill to implement a reliable new OSB binder adhesive system comprising of various in-situ reactions of the synthetic/natural polymer components in the OSB mill press and finished board. The produced OSB boards exhibit mechanical strength and water resistance properties equal to or superior to OSB boards made with the spray dried phenolic adhesives normally used as the sole OSB binder. The formaldehyde emissions from board pressing operations and from the final finished OSB board are reduced because the tannin acts as a formaldehyde "scavenger" in-situ. The OSB produced with the novel binder mix shows improved mould growth resistance.

Inventor: WEISSMAN SHERMAN
IPC: C12Q1/6809
Filed: 1999-05-05
Abstract: Methods are disclosed to identify T lymphocyte genes that are differentially expressed upon exposure to a pathogen (viral or bacterial), immunogen, antigen, or in a sterile inflammatory disease, autoimmune disease, immunodeficiency disease, lymphocytic cancers, or graft versus host rejection. The method involves the preparation of a gene expression profile of a T lymphocyte population exposed to a pathogen or isolated from a subject having one of the aforementioned pathologies and comparing that profile to a profile prepared from quiescent T lymphocytes. The present invention is particularly useful for identifying cytokine genes, genes encoding cell surface receptors and genes encoding intermediary signalling molecules. Related methods for identifying therapeutic or prophylactic immunomodulatory agents are presented. Articles of manufacture are disclosed that comprise selected grouping of nucleic acids, affixed to a solid support, that correspond to genes that are differentially expressed in various populations or subpopulations of T lymphocytes at variations stages of T cell differentiation, in quiescent versus activated T lymphocytes or normal versus diseased T lymphocytes.

Title: Location based routing for mobile ad-hoc networks
Inventor: REGE KIRAN M
IPC: H04L12/56
Filed: 2000-12-18
Abstract: In an ad-hoc mobile network, a geometry-based routing algorithm (GRA) is used to route traffic from a source node to a destination node. In the GRA, a source node maintains location information and routing information for all nodes in a local area and approximate location information for at least some nodes outside the local area. If the source node has to send a packet to a destination node outside their local area, then the source node uses the approximate location information of the destination node to identify which node in its local area is closer to the destination node than the source node. The source node then sends the packet to the identified local node for further routing.

Title: A method and system for providing copy-protection on a storage medium and storage medium for use in such a system
Inventor: JOCHEMSEN ROBERT
IPC: G11C16/22
Filed: 2000-03-14
Abstract: In a method for providing copy-protection services on a storage medium (for instance a solid state memory module), the data are arranged in sectors to which a field (S4T) is associated, where said field contains a random value Ri which is changed randomly when writing data to said sector. By encrypting the data stored on the medium using a key which depends critically on said random numbers, bit-by-bit copies (apart from said random numbers, which can not be deterministically changed by an application) to a second storage medium or recopies from some intermediate storage medium, can not be decrypted because the values of said random numbers will have changed, thus preventing unauthorized duplication and replay attacks.

Patent CA-2338778-A1 (CA)
Inventor: RACZ ANDRAS
IPC: H04L12/56
Filed: 1999-07-27
Abstract: A link-level flow control method for serving ATM cell streams arriving from a number of packet sources determines a requested bandwidth share for each packet source and queues ATM cells arriving from the packet sources in a shared FIFO buffer. Based on the number of transmitted ATM cells during a pre-defined time period, non-violating packet sources and violating packet sources are identified. The non-violating packet sources are those packet sources that during the predefined time period do not require more than their requested bandwidth share, and the violating packet sources are those packet sources that during the same period require more than their requested bandwidth share.  In order to maintain fairness among the packet sources, the non-violating packet sources are granted no more than their requested bandwidth share, with the remaining bandwidth not granted to the non-violating packet sources being granted to the violating packet sources.

Patent CA-2341847-A1 (CA)
Inventor: SAMARASOORIYA VAJIRA N S
IPC: H04L27/00
Filed: 2001-03-22
Abstract: A method and sytem for achieving carrier frequency synchronization in a high speed receiver. A feedback loop in a carrier recovery system is operated at a down-sampled rate until carrier lock is detected. The output of a phase accumulator, operating at the down-sampled rate, is then extrapolated to provide extrapolated outputs to provide outputs at the original symbol rate. Addresses for a look-up table are then generated from the combined phase accumulator outputs and extrapolated outputs, such that the frequency and phase compensation offsets provided to a phase derotator and slicer are at the original symbol rate. The total pipeline delay as seen by the carrier recovery system is thus reduced. This in turn allows for more efficient correction of residual carrier frequency errors present in a complex baseband signal.
