US Classification:

361181, 178 1802, 307116, 307125, 340644, 361179

Abstract:

A technique for controlling a switching circuit includes one or more sensing circuits that generate signals based upon the presence of an actuating object and upon a randomly applied strobe signal. The generated signals are sampled and are used as a for determining the state of an output signal. The sensing circuit may generate the signals based upon capacitive coupling with the actuating object. The randomization of the sampling enhances immunity to periodic noise. Where more than one sensing circuit is included, the output of the circuits may be considered together for determining the state of the output signal, such as based upon predetermined ranges of signal levels. Signals of the sensing circuit may be sampled in the absence of the strobe to provide an indication of the relative noise level. If the noise level is determined to be elevated, the output signal may not change states.

International Classification:

US Classification:

307/125000

Abstract:

A technique for controlling a switching circuit, such as a relay, includes one or more sensing circuits that generate signals based upon the presence of an actuating object and upon a randomly applied strobe signal. The generated signals are sampled and are used as a basis for determining the state of an output signal. The sensing circuit may generate the signals based upon capacitive coupling with the actuating object. The randomization of the sampling provides enhanced immunity to periodic or cyclic noise. Where more than one sensing circuit is included, the output of the circuits may be considered together for determining the state of the output signal, such as based upon predetermined ranges of signal levels. Signals of the sensing circuit may be sampled in the absence of the strobe to provide an indication of the relative noise level. If the noise level is determined to be elevated, the output signal may not change states.

Abstract:

Methods for using an apurinic/apyrimidinic endonuclease, capable of cleaving both single- and double-stranded cDNA, for fragmentation and labeling of single stranded or double stranded DNA molecules are provided. Amplification methods that generate single-stranded amplified cDNA are also disclosed. In the subject methods AP sites in a population of nucleic acids are cleaved by an AP endonuclease that is active on both double and single stranded DNA. Fragments may be end labeled. In preferred embodiments APE 1 is used. The methods may be used in a variety of applications where end-labeling single or double stranded DNA is desired.

Abstract:

Methods for fragmenting and labeling DNA in a single reaction volume and incubation step using a uracil DNA glycosylase, an apurinic/apyrimidinic endonuclease, and a terminal transferase are disclosed. In a preferred embodiment the UDG, AP and TdT activities are first mixed together to form an enzyme mixture and then the enzyme mixture is mixed with the uracil containing DNA. The fragmentation and labeling reactions thus take place simultaneously as part of the same reaction. The methods may be used in a variety of applications where fragmenting and end-labeling single or double stranded DNA is desired.
