  • Patent number: 8505235
    Abstract: An electronic animal trap with a CPU-controlled, rearming, three-killing-plate configuration and extended killing cycle for trapping and exterminating larger rodents such as rats. The high-voltage output circuit is connected to a pair of killing plates which are activated with a high-voltage pulse train for a killing cycle when a pest of known impedance is sensed across the pair of plates. A third killing plate, electrically coupled to a first plate of the pair of plates, is brought to the voltage level of the first plate within approximately 1 msec of circuit activation for increased kill and escape-prevention capabilities.
    Type: Grant

  • Patent number: 7010882
    Abstract: An electronic animal trap with a CPU-controlled, rearming, high voltage output circuit for trapping and exterminating pests. The high-voltage output circuit is connected to a pair of killing plates which are activated with a high-voltage pulse train for a period of time constituting a killing cycle when a known impedance is sensed across the plates. If, upon conclusion of the killing cycle, the impedance remains across the plates, the circuit activates a visual indicator to alert a user that the trap contains a dead mouse. However, if the impedance increases to that of an open circuit, likely meaning the animal has escaped, the circuit automatically rearms itself and no visual indicator is initiated.

  • Patent number: 5752517
    Abstract: Intraoperative ultrasound probes are described having contoured side surfaces which enable the probe to be held between the fingers of a surgeon during a surgical ultrasound procedure. The probes advantageously permit the surgeon to conduct a tactile examination of organs of a patient with the hand and fingertips while holding the probe.
