Granted: 2005-05-12
Abstract: A method of determining the presence and identity of a variation in a nucleotide sequence between a first polynucleotide and a second polynucleotide comprising, first, providing a sample of the first polynucleotide and selecting a region of the first polynucleotide potentially containing the variation. Then, the selected region is subjected to a template producing amplification reaction to produce a plurality of double stranded polynucleotide templates which include the selected region. Next, a family of labeled, linear polynucleotide fragments is produced from both strands of the template simultaneously by a fragment producing reaction using a set of primers. Then, the location and identity of at least some of the bases in the selected region of the first polynucleotide is determined using the labels present in the fragments. Next, the location and identity of the bases determined is compared with the location and identity of bases from a second polynucleotide, thereby identifying the presence and identity of a variation in a nucleotide sequence between the selected region of the first polynucleotide and a corresponding region of the second polynucleotide.

Title: D.c. offset compensation in a radio receiver
Inventor: DENT PAUL WILKINSON
IPC: H04B1/30
Filed: 1991-09-04
Granted: 2000-11-28
Abstract: A zero-IF radio receiver eliminates DC offset without distortion or loss of the low-frequency and DC components of the received or desired signal by initially differentiating the received signal to filter out the DC offset. The signal is amplified to a suitable level and then integrated to recapture the original DC and low frequency signal components. The integration essentially restores the filtered components to the original value in the amplified signal using an arbitrary constant of integration of bounded magnitude to generate a restored signal. Using various techniques that exploit predetermined signal patterns or inherent signal properties of the desired signal, the DC offset can be reasonably estimated. The DC offset estimate is then subtracted out of the restored signal leaving the amplified, received signal substantially free from distortion.     An advantageous method for differentiating and digitizing the received signal uses the technique of companded delta modulation.

Abstract: In a reflective optical modulator (1) light enters through an optical waveguide (2) into a Fabry-Perot resonator (5) which couples it back into the optical waveguide (2).          The modulation is effected by detuning the Fabry-Perot resonator (5).  The Fabry-Perot resonator (5) is here composed of the end face (4) of the optical waveguide (2) through which the light enters and is coupled back and of a first reflective surface (3) disposed opposite this face (4).    When such a reflective optical modulator (1) is employed in a transceiver module (40), the light entrance surface of a photodiode (11) is the first reflective surface (3).    The first reflective surface (3) is disposed on a flexural or compression-type resonator (8).  The resonator length (x) can also be detuned by varying the refractive index between the two reflective surfaces (3, 4).
