Patent number: 7433657Abstract: A transmitter has a signal generator, an amplifier, a detection circuit, a comparison circuit, a loop filter, and an adjustable clock. The signal generator produces a signal. The signal is produced with a first frequency characteristic and contains frequency-related information. The detection circuit detects the first frequency-related characteristic and generates an associated signal in response. A comparison circuit compares the signal from the detection circuit and another signal. It outputs a signal associated with the difference between the two. A loop filter receives the output of the comparison circuit and generates a signal to the signal generator in. The loop filter is clocked at a second frequency by a signal from a clock circuit. The clock circuit can compare the first frequency and the second frequency, and can change the second frequency based upon a relationship between the two frequencies.Type: GrantFiled: November 8, 2005Date of Patent: October 7, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Paul Cheng-Po Liang, Rajesh D.

Patent number: 5914230Abstract: The present invention relates to a method for detecting or amplifying and detecting a target polynucleotide sequence. The method comprises providing in combination (i) a medium suspected of containing the target polynucleotide sequence, (ii) all reagents required for conducting an amplification of the target polynucleotide sequence when amplification is desired, and (iii) two oligonucleotide probes capable of binding to a single strand of the product of the amplification. At least one of the probes has two sequences that either (i) are non-contiguous and bind to contiguous or non-contiguous sites on the single strand or (ii) can bind to non-contiguous sites on the single strand. Each probe may contain a label. The combination is subjected to conditions for amplifying the target polynucleotide sequence. Next, the combination is subjected to conditions under which both of the probes hybridize to one of the strands to form a termolecular complex, which is detected by means of the label.Type: GrantFiled: December 20, 1996Date of Patent: June 22, 1999Assignee: Dade Behring Inc.Inventors: Yen Ping Liu, Rajesh D.
