  • Vacuum extraction business method
    Publication number: 20050015098
    Abstract: The invention is a method of monitoring and recording factors that occur during a vacuum-based fetal extraction. In one embodiment, the method includes counting a number of pulls made with a vacuum extraction cup that is attached to a fetal head, counting a number of times the vacuum extraction cup pops off the fetal head, counting an amount of time the vacuum extraction cup is attached to the fetal head, automatically recording a maximum cup pressure detected during the time the vacuum extraction cup is attached to the fetal head, and counting an amount of time a pressure is within a predetermined percentage range of the maximum pressure detected during the time the vacuum extraction cup is attached to the fetal head.

  • Opto-electrically controlled direct current motor speed control circuit
    Patent number: 5896487
    Abstract: A dc motor speed control circuit is provided. A first circuit utilizing an opto-electric sensor for providing an input signal corresponding to a desired dc motor speed is connected to a second circuit and the second circuit is connected to the dc motor, wherein the second circuit responds to the input signal and causes current to flow through the dc motor corresponding to the input signal. A temperature circuit, voltage level circuit and current level circuit may also be connected to the second circuit to control the dc motor.
