  • Remote audible alarm accessory for detection instruments with audio outputs
    Patent number: 11140476
    Abstract: In an example, a circuit includes: an AC piezoelectric audio transducer configured to receive an audio output signal of a source; a step-up transformer having a primary winding to receive the audio output signal of the source; a bridge rectifier having an input connected to a secondary winding of the step-up transformer; and a DC piezoelectric audio transducer connected to an output of the bridge rectifier. The AC piezoelectric audio transducer, the step-up transformer, the bridge rectifier, and the DC piezoelectric audio transducer are configured to produce an audible alarm signal based on the audio output signal of the source without powered amplification, which includes an audible sound from the AC piezoelectric audio transducer and another audible sound from the DC piezoelectric audio transducer.

  • Methods for generating databases and databases for identifying polymorphic genetic markers
    Publication number: 20030207297
    Abstract: A method for discovery of a polymorphism in a population is provided. The method includes the steps of obtaining samples of body tissue or fluid from a plurality of organisms; isolating a biopolymer from each sample; pooling each isolated biopolymer; optionally amplifying the amount of biopolymer; cleaving the pooled biopolymers to produce fragments thereof; obtaining a mass spectrum of the resulting fragments; and comparing the frequency of each fragment to identify fragments present in amounts lower than the average frequency, thereby identifying any polymorphisms.
