  • Publication number: 20240374280
    Abstract: An ultrasonic instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.

  • Patent number: 4254501
    Abstract: An electrically and mechanically modular design of a high impedance, passive transceiver is disclosed for use in distributed, serial transmission systems to provide half uplex interfacing to multiple users with minimum loading and reflection. The transceiver is selectively operable in either of two modes: a receive mode for receiving low-level serial, bi-phase (3 state) Manchester coded signals and transmitting (2 wire, 2 state) signals at transistor-transistor logic (TTL) levels; and a transmit mode for receiving (2 wire, 2 state) signals at TTL levels and transmitting the low-level, serial bi-phase, (3 state) signals on the bus.

  • Patent number: 3992581
    Abstract: A phase locked loop repeater for reshaping a non-return to zero (NRZ) data stream. A transition detector receives the input data stream from a coaxial cable in a degraded condition in terms of amplitude and phase distortion and produces reference pulses whose positions are very nearly independent of the direction of the transition of the input data. These reference pulses, along with clock pulses from a voltage controlled oscillator (VCO), are applied to a phase comparator and when these signals differ in phase, a voltage is developed for modifying the frequency of the VCO. The clock signals from the VCO are applied to the clock input of a D-type (edge triggered) flip-flop, to which is also applied the incoming data stream. The D-type flip-flop changes state in accordance with the incoming data only at the leading or trailing edge of the clock pulses. As such, the timing and amplitude of the data stream is reconstructed for reapplication and further transmission on said coaxial cable.

  • Patent number: 3983323
    Abstract: A finite drive impedance, unbalanced transmission line system for transmitting only the differentiated transitions of a binary level digital signal is disclosed. The transmission line arrangement includes two identical, balanced-bridge transceivers at opposite ends of a coaxial cable whose alternating current (AC) transmission line characteristics are utilized to maintain waveform timing, i.e., the spacing between the differentiated transitions, independent of transmission line length. Integrated circuit (IC) transistor-transistor-logic (TTL) is utilized for the active elements.

  • Patent number: H1262
    Abstract: The present invention is directed to a semi-automatic rod examination gauge for performing a large number of exacting measurements on radioactive fuel rods. The rod examination gauge performs various measurements underwater with remote controlled machinery of high reliability. The rod examination gauge includes instruments and a closed circuit television camera for measuring fuel rod length, free hanging bow measurement, diameter measurement, oxide thickness measurement, cladding defect examination, rod ovality measurement, wear mark depth and volume measurement, as well as visual examination. A control system is provided including a programmable logic controller and a computer for providing a programmed sequence of operations for the rod examination and collection of data.
