Title: Method for call admission in packet voice system using statistical multiplexing and dynamic voice encoding
Inventor: WANG YUNG-TERNG
IPC: H04Q11/04
Filed: 1998-09-30
Abstract: An AAL2/SSCS packet voice system multiplexes various forms of voice-band traffic including voice packets, fax packets, and data packets into a virtual circuit (VC). This AAL2/SSCS packet voice system executes a dynamic call admission algorithm that takes into account call type in deciding whether to admit a new call to the VC. In particular, this approach takes into account different bandwidth needs for different call types. The AAL2/SSCS packet voice system also performs bit or block dropping on voice packets to mitigate the effects of traffic congestion. The bit or block dropping is done based on the packet queue fill value exceeding at least one queue threshold. Further, the AAL2/SSCS packet voice system also dynamically varies a queue threshold as a function of capacity.

Patent CA-2254312-A1 (CA)
Inventor: ELSNER NORBERT
IPC: H01L35/34
Filed: 1998-11-20
Abstract: A thermoelectric module contains thermoelectric elements installed in a gapless eggcrate. An eggcrate having walls without gaps is formed using a technique such as injection molding. This gapless eggcrate provides insulated spaces for a large number of p-type and n-type thermoelectric elements.      The absence of gaps in the walls of the spaces virtually eliminates the possibility of interwall shorts between the elements even when electrical connections are made by metal spray techniques. Fabrication of the gapless eggcrate can be automated using several available techniques such as molding and casting to greatly reduce the labor cost of fabricating thermoelectric eggcrates as compared to prior art techniques of fabricating eggcrates. Thermoelectric elements, both p-type and n-type, are fabricated and are inserted into the insulated spaces in the gapless eggcrate in a predetermined manner to provide the desired thermoelectric effects for a predetermined type of application. Electrical connections are established on both the hot and cold sides of the module to connect the thermoelectric elements in series or parallel as desired.

Title: Method for attenuation of reverberations using a pressure-velocity bottom cable
Inventor: MOLDOVEANU NICOLAE
IPC: G01V1/38
Filed: 1997-04-24
Abstract: A method is described that attenuates reverberations in ocean bottom cable data used to generate a seismic profile. First, a seismic wave is generated and recorded by pressure and particle velocity sensor pairs. Adding the product of the pressure data times the absolute value of the velocity data and the product of the velocity-data times the absolute value of the pressure data eliminates-reverberations, leaving a combined signal that is a function of only the primary wave response signal. Dividing this combined signal by 2 and a sensitivity scaling factor, and then taking the square root of the result produces the magnitude of the primary signal. Replacing the positive/negative sign of the combined signal that existed before taking the absolute value provides the proper polarity. The data are then incorporated into a seismic profile.

Title: Efficient non-viral transduction and culture of erythroid cells
Inventor: MATTHEWS KATHRYN
IPC: C07K14/71
Filed: 1999-01-25
Abstract: The present invention involves 1) efficient non-viral gene transfer into human erythroid progenitors cells and 2) use of a constitutively active human EpoR  gene to prolong the lifespan of progenitor cells. CD34' cells enriched from umbilical cord blood LDMNC are cultured er vivo at a low density in the absence of supportive stroma for 7 to days in a serum-free defined culture medium with the addition of IL-3, SCF and EPO. At this time, cells expand < 70 fold and hematopoietic progenitors are present at a frequency of 25 BFU-E, 28 CFU-E and 10 CFU-GM per 1 x 10 5 cells as detected by methylceliulose colony forming assay. Approximately 2% are CD34~ while 40% are GIyA~. Hematopoietic cells cultured in this manner are rendered highly susceptible to gene transfer by electroporation and a gene transfer effciency of >25% is obtained.  The lifespan of erythroid progenitors that persist at the point of electroporation can be prolonged through the introduction of a constitutively active form of the human EpoR  gene.This invention is useful for (1) genetic modification of hematopoietic stem cells, especially erythroid progenitors and (2) the propagation of erythroid cells in vitro for the production of hemoglobin.
