  • Patent number: 6259680
    Abstract: The present invention relates to an improved method and apparatus for echo cancellation in a communication system utilizing a bidirectional transmission medium. The invention significantly reduces computational overhead associated with echo cancellation by using sub-Nyquist sampling in the echo path. In particular, the invention relates to a method and apparatus for echo cancellation in a communication system utilizing different signaling or baud rates in the transmit and receive directions, whereby the computational overhead of the echo cancellation is significantly reduced as compared to traditional methods. In a preferred embodiment herein, the present invention reduces by one-half the computational overhead associated with echo cancellation in a data communications system utilizing symmetrical information rates at asymmetrical signal rates.

  • Patent number: 5940307
    Abstract: The present invention relates to a method for predicting the tendency of a protein to form amphiphilic .alpha. or .beta. structure, wherein a series of values for U are calculated for spans of x residues, where the equationU.sub..alpha.x =H.sub.x -<pt>is used to predict regions of amphiphilic .alpha. structure and the equationU.sub..beta.x =H.sub.x <pt>is used to predict regions of amphiphilic .beta. structure, and where H.sub.x is the average hydrophobicity for a span of x residues, .mu..sub.x is the hydrophobic moment, and <pt> is the position dependent turn propensity. When the values for U.sub..alpha.x and U.sub..beta.x are represented graphically, peaks are predicted to represent regions of .alpha. and .beta. structure, respectively.

  • Patent number: 5868134
    Abstract: A retinal disease analyzer processes data obtained by processing a color retinal image and measured visual field data provided by a perimeter to detect the condition of the optic disc and defects in the nerve fiber bundles for the clinical analysis of the condition of the optic disc and the defects in the nerve fiber bundles, and combines detected information on a fundus coordinate system taking into consideration the arrangement of the nerve fiber bundles for the comprehensive analysis of the condition and the degree of progress of glaucoma. The detected information is analyzed on the basis of the distribution pattern of the nerve fiber bundles or the corresponding fundus coordinate system to integrate all the data for analysis. The condition and the degree of progress of glaucoma can be determined on the basis of the integrated data.

  • Patent number: 5863354
    Abstract: Thin-film photoelectric conversion elements are spaced from each other on an insulating belt-like film. Respective common conductive tapes are soldered to the terminal electrodes of the elements at the two edges of the film. The common conductive tape is in contact with non-adhesive resin in gap portions between adjacent photoelectric conversion elements. For forming a module, the assembly can be cut at these portions, followed by removal of the non-adhesive resin to expose the common conductive tape for external connection of the module.

  • Patent number: 5824702
    Abstract: A method of inhibiting the harmful effect of UVR exposure to the human skin comprising topically applying a therapeutically effective amount of genistein to the skin at a time sufficiently close to the time of UVR exposure to inhibit UVR-induced damage to the skin. The genistein appears to act as a chemo preventative agent since it has no appreciable sun blocking effect. The genistein may be mixed with a variety of carriers and skin treatment compositions.

  • Patent number: 5802357
    Abstract: A technique for efficiently joining multiple large tables in a database system with a processor using a small main memory. The technique utilizes a join index and minimizes the number of Input/Output operations while maximizing the use of the small main memory through a buffer allocation process. Three embodiments of the technique are described all of which use the parallel-merge operation. The first technique, slam-join, is for joining two tables and does not require any pre-allocation of buffers to perform the join operation. The second technique, multi-slam-join, is for joining three or more tables and adds the parallel-merge technique to a join technique which partitions memory to be used for an efficient join operation. The third technique, called parallel-join, processes each input table completely independently using the parallel-merge technique. The parallel-merge technique identifies the lowest value from multiple files and orders all the values from lowest to highest.

  • Patent number: 5799507
    Abstract: A process for the recovery of propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled and/or expanded to partially condense it, then separated to provide one or more C.sub.3 containing liquid steams and a first vapor stream. These streams are then directed into a distillation column wherein a second vapor stream is separated to recover a product containing the major portion of the C.sub.3 components and heavier hydrocarbon components. A distillation stream is withdrawn from the column below the feed point of the first vapor stream and is then directed into heat exchange relation with the second vapor stream to cool the distillation stream and condense at least a part of it, forming a condensed stream. At least a portion of the condensed stream is directed to the distillation column as its top feed.
