IPC: E02B3/02
Filed: 2000-05-29
Abstract: Arrangement for fairways in brackish water tidal zones to prevent or minimize deposits of silt and/or sand in a branch or enlargement of such fairways. The invention is realized by the installation of a flow wall system. At the entrance to the branch or expansion, a current deflection wall is submerged in the fairway at an upper level some distance from the bank so that a channel is formed near the entrance to the branch or enlargement to direct an flood tide into the branch or enlargement and a deflection sill is juxtaposed with the partition at a lower level to divert an incoming near-bed current of the fairway away from the entrance to the branch or enlargement. The cross sectional area of the channel is small when compared with the cross sectional area of the entrance to the branch or enlargement.

Abstract: Monitoring clock ticks of a CPU ("computer processing unit") during its execution of a software program is provided. The clock ticks are monitored, and an elapsed runtime is updated, throughout execution of the program on a periodic basis. The elapsed runtime is stored in a hidden file or within a key inside a software registry. Updating runtime on a periodic basis ensures accurate tracking of runtime usage even in the event of a program crash, allowing the user to restart the program without the penalty of lost runtime. The software package will continue to operate until the elapsed runtime exceeds a predetermined evaluation time, at which point the software package is fully or partially disabled until it is registered by the user. An alternative to the hidden tracking file or registry is to use a World Wide Web push/pull technology to store runtime information at the software provider's site, allowing the provider to modify the evaluation period on a pay-per-use basis.

Patent CA-2317912-A1 (CA)
Inventor: ALB CRISTIAN
IPC: H04L1/00
Filed: 2000-09-07
Abstract: A method and communications device for controlling the line rate used on a communications link. The method includes receiving frames of digital information, computing a measure of the number of frames received in error in a sliding time window and generating a command to change the line rate as a function of the measure. The use of a sliding time window captures variations in the line quality over an extended period of time; thus, significant disturbances which might otherwise be missed are captured. The measure of the number of frames received in error is computed by applying a many-to-one mapping to the actual number of frame errors received since a previous sampling instant; thus, insignificant short-term disturbances which might otherwise temporarily corrupt the line quality estimate are eliminated. As a result, commands to change the line rate are based on a better estimate of line quality and the incidence of thrashing in the presence of recurring noise bursts is reduced, leading to increased data throughput. A back-off timer may be used for preventing an upgrade in line quality from occurring immediately following a downgrade, further decreasing the incidence of thrashing.

Title: Resorbable, macro-porous, non-collapsing and flexible membrane barrier for skeletal repair and regeneration
Inventor: LEMPERLE STEFAN M
IPC: A61B17/68
Filed: 1999-01-22
Abstract: A resorbable, flexible implant in the form of a continuous macro-porous sheet is disclosed. The implant is adapted to protect biological tissue defects, especially bone defects in the mammalian skeletal system, from the interposition of adjacent soft tissues during in vivo repair. The membrane has pores with diameters from 20 microns to 3000 microns. This porosity is such that vasculature and connective tissue cells derived from the adjacent soft tissues including the periosteum can proliferate through the membrane into the bone defect. The thickness of the sheet is such that the sheet has both sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired, and sufficient tensile strength to allow the sheet to be so shaped without damage to the sheet. The sheet provides enough inherent mechanical strength to withstand pressure from adjacent musculature an does not collapse.

Title: Surgical knife - capsulotome
Inventor: CHRISTOPOULOS DIONISSIOS
IPC: A61F9/007
Filed: 2000-02-16
Abstract: Surgical knife which can be used in cataract operations and especially in cutting one part of the anterior capsule. The capsulotome is a circular (round) blade (fig. 3 .beta.) that has the characteristic of being closed and put in the cylinder (26) (fig. 3a). The knife's blade (28) is put inside the cylinder (26) closed because it must firsly pass through a small diameter tunnel before entering the anterior chamber. When the cylinder (26) is entering the anterior chamber, the knife (28) is coming out of the cylinder (26) because of the movement of the bolt (22) and with the help of the antidiametrical sheets (24) it takes a circular (round) shape (fig. 7) cutting the membrane (32) of the anterior capsule circularily just with a simple touch. For coming out of the anterior chamber, the knife (28) is being closed, it is put again in the inner part of the cylinder (26) and comes out of the small tunnel. The knife's diameters vary from 3,5 mm to 9 mm, increasing for half a millimeter, that's why there are twelve different capsulotomesto fit with each diameter. In this way we can choose the diameter of the knife (28) according to the diameter of the membrane (32) that we want to cut. The external diameter of the cylinder (26) can be constructed from 2 mm to 3 mm in order the cylinder (26) to be able to enter in a small tunnel 3,2 mm or even smaller.

Inventor: WOOD WILLIAM I
IPC: C12Q1/68
Filed: 1999-12-16
Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of genes that are amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contribute to tumorigenesis. Accordingly, the proteins encoded by the amplified genes are believed to be useful targets for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as predictors of the prognosis of tumor treatment. The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are  vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
