Patent CA-2208228-C (CA)
Inventor: HELMS CHARLES F
IPC: D02G3/02
Filed: 1996-12-03
Granted: 2000-09-19
Abstract: Synthetic filaments include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier. The additive system is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more  into the melt  flow of polymeric material,  melt-spun filaments having different additive attributes may be produced on a continuous basis (i.e., without shutting down the spinning operation). The filaments may be included in yarns which are formed into carpet structures.

Abstract: One or more portions (221) of a database (220) which a primary server (106) uses to process client requests are duplicated (211) on one or more supplemental servers (105). As the clients demand for service increases and the processing load on the primary server becomes excessive (400), the primary server automatically off-loads the processing of those portions of the client requests that require one or more of the duplicated portions onto the supplemental servers by substituting (402) a secondary page (253) or a secondary object in its database that points to the one or more duplicated portions in the supplemental servers for a corresponding primary page (252) or a primary object in its database that points to the one or more duplicated portions in its database. The supplemental servers then serve the portions of the client requests that require the one or more of the duplicated portions. As demand for service decreases and the primary server becomes underloaded (404), it automatically restores (406) the primary page or the primary object in its database and resumes serving the entire client requests.

Abstract: An apparatus for optically measuring marine conditions comprising a tunnel defining a sampling volume for water, a laser diode line generator for generating a beam of light and reflector means for directing the beam of light across the sampling volume through the water in a direction substantially perpendicular to the direction of flow of the water, and a plurality of photo-sensor elements of similar size disposed for receiving and measuring the intensity of the light beam after passage through the water. The effective size of each photo-sensor element (about 1 mm 2) is greater than the smallest particle to be detected and smaller than the largest organism to be measure. The photo-sensor elements generate an output signal providing an average level representative of turbidity of the water sample, and an rapidly changing attenuated level caused by passage of an organism or particle. Measuring the attenuation of the output signal caused by passage of a particle or organism provides a measure of the size of the particle or organism. By measuring the number of adjacent photo-sensor elements having an attenuated level caused by occlusion by an organism larger than a single photo-sensor element, the transverse size of an organism can be determined. Measurement of the transit time of an attenuated level, indicates the longitudinal size of an organism, or the rate of passage of a particle four providing a measure of the flow rate through the tunnel.  Combining transverse and longitudinal size data provides a shape outline of the organism.

Abstract: A female power contact which is energized only upon insertion of a male plug. The contact includes a plunger which is biased toward a position which blocks accidental finger insertion into the contact.  The plunger also contains sharp points on its outer edge to further prevent accidental finger insertion into the contact.

Abstract: A digital timing recovery system advantageously employs both demodulated I-phase and Q-phase components to more accurately locate the synchronization signal of an incoming VSB signal. The Q-phase component is advantageously employed to detect the phase error. The use of the Q-phase component provides a more accurate measure of the phase error and results in a larger (wider) acquisition range for timing frequency offset. More specifically, the timing recovery system of this invention performs symbol clock recovery based on the VSB signal segment synchronization (sync) signal and generates a pulse density modulated (PDM) phase difference signal that controls a voltage controlled crystal oscillator (VCXO) in the phase-locked loop. This is realized, in one embodiment of the invention, by correlating received sync segment data with the known sync signal pattern and searching for "peaks" in the correlation values that are periodic at the known sync segment data rate. Once the sync pattern is found, the correlation values for adjacent samples are advantageously employed to generate the necessary feedback control signal value for the VCXO. Technical advantages of applicants' unique invention are that the need for an analog synchronous detector is eliminated, a more accurate measure than that obtained by prior known systems is obtained and a wider acquisition range is obtained for timing frequency offset.

Abstract: A system and device for, and method of, processing baseband signals to comba t ISI and non-linearities on a communication system having a local loop. An actual alphabet is formed (471) from the signals actually transmitted on a channel (250). The alphabet may be used for symbol decoding (470), for example, and may avoid erroneous symbol predictions that could occur if an ideal or proscribed alphabet were used. Conventional phone systems have local loops with conventional lin e interfaces believed to have non-linearities vis-a-vis the proscribed companding algorithm. In particular, baseband signals created fro m the inverse quantization mechanisms inherent in conventional line interfaces have non-linear distortions. The actual alphabet therefore corresponds to the low fidelity signals actually transmitted by the line interface (250), with each symbol being an estimate of the signals actually transmitted (475). The estimate may be formed from an averaging function. An equalizer (460) may be used to combat ISI and other channel distortion. The alphabet and the equalizer may be updated with an error signal that is indicative of the accuracy of the alphabet's estimates (481).

Abstract: The present invention relates to a temperature-controlled pH-dependant formation of ionic polysaccharide gels, such as chitosan/organo-phosphate aqueous systems, and methods of preparation thereof.  While chitosan aqueous solutions are pH-dependant gelating systems, the addition of a mono-phosphate dibasic salt of polyol or sugar to chitosan aqueous solutions leads to further temperature-controlled pH-dependant gelation. Solid organo-phosphate salts (1-20 % w/v) are added and dissolved at low temperature (10 ° C) within 0.5 to 4.0 % w/v chitosan in aqueous acidic solutions.  Aqueous chitosan/organo-phosphate solutions are initially stored at low temperatures (4 °C), then endothermally gelated within the temperature range of 30 to 60 °C. Chitosan/organo-phosphate solutions rapidly turn into gels at the desired gelation temperature. Gelation can be ex vivo within any receivers or molds, or in situ in animals or humans (in vivo) so as to fill a tissue defect or cavity.
