Patent CA-1291811-C (CA)
Title: Write clock generator for time base corrector
Inventor: NAKAMURA YOSHIYUKI
IPC: H04N9/896
Filed: 1986-03-13
Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE          A write clock generator for a time base corrector incorporated in a video tape recorder can generate a write clock signal including accurate phase and frequency fluctuation information on a reproduced video signal in spite of a simple circuit configuration. A write clock signal is generated from a VCO oscillated in response to a reproduced burst signal, and further the VCO is so controlled on the basis of a frequency difference between the oscillated write clock signal and a frequency fluctuation signal such that the frequency difference may be eliminated.  The frequency fluctuation signal is generated in response to a horizontal synchronizing signal so as to include time base fluctuations in a reproduced video signal.

Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE      Immobilization of nucleic acids, e.g., DNA and RNA, by contact with a solid support comprising nylon whose amide groups have been partially solvolyzed.  Solvolysis of the nylon support can be accomplished by treatment with an alkylating agent such as a trialkyloxonium salt under anhydrous conditions followed by addition of water.  The immobilized nucleic acid is particularly useful as an immobilized probe in hybridization assays to detect specific polynucleotide sequences in a test sample.

Abstract: ABSTRACT     A particle analyzing method and apparatus for white blood cell (leukocyte) differentiation by optical and electronic measurements, without the use of dyes, on a flowing stream of leukocytes.  A hydrodynamically focused stream of the leukocytes, in native condition, is passed into and through a beam of radiant energy in a flow cell, whereby the beam is uniquely scattered by different ones of the subpopulations of the leukocytes.  The scattered light impinges upon light collection means disposed adjacent the flow cell.  For eosinophil detection, the scattered light is collected at angular positions from about 10° to 70° relative to the axis of the beam. Other of the leukocyte subpopulations are differentiated relative to the eosinophils and each other by optical and/or electronic measurements, especially including the Coulter Principle of particle analysis.

Title: Jitter-invariant switched capacitor pulse shaper
Inventor: COLBECK ROGER
IPC: H04B3/06
Filed: 1988-05-27
Granted: 1991-11-26
Abstract: ABSTRACT           The present invention provides an output pulse signal from an input digital signal which can be fabricated in an integrated circuit, and produces an output signal which retains the desired pulse shape unaffected by jitter.  In the present invention the pulse shape is formed by using a switched capacitor FIR filter to form the pulse shape (referred to herein as a pulse shaper), and then by controlling the clocking of the digital signals used to operate the pulse shaper to control the timing of different segments.  The result is an output signal which has jitter but retains the desired pulse shape.  Since a phase corrector which senses jitter can control the clocking, the output pulse shape is unaffected by jitter.  The invention can be produced in an integrated circuit since switched capacitor pulse shapers are used, rather than a continuous time filter.  An analog pulse signal is produced from an input digital signal by applying the input digital signal to serial shift registers, each spanning less than a baud, operating switched corresponding ones of the shift registers to form different parts of an output signal, summing the output signals in time to form a combined output signal, and low pass filtering the combined output signal to form the analog pulse signal.
