  • SURGICAL GENERATOR FOR ULTRASONIC AND ELECTROSURGICAL DEVICES
    Publication number: 20240148429
    Abstract: A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

  • Fingerprinting system and method
    Patent number: 5263742
    Abstract: A system and method for taking and developing a fingerprint wherein the subject's fingers are not dirtied or exposed to chemicals. The fingerprint is recorded on a layer of adhesive adhered to a sheet of transparent material. The print is developed by making a copy of it on a sensitized surface by back reflecting radiant energy through the adhesive whereby the print is imaged.
