Filed:

Oct 20, 2003

Appl. No.:

10/687829

Inventors:

Christopher T. Rich - Leola PA, US
Larry L. Harman - Abbottstown PA, US
David L. Anderson - Lititz PA, US
Michael J. Gehret - Lititz PA, US

Assignee:

Woodstream Corporation - Lititz PA

International Classification:

A01M 2338

US Classification:

43 98

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.

International Classification:

A01M 19/00
A01M 23/38

US Classification:

43 98

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 said pair of plates. A third killing plate, electrically coupled to a first plate of said 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.

Appl. No.:

11/078486

Inventors:

Larry Harman - Abbottstown PA, US
Edward Holliday - Lititz PA, US

International Classification:

A01K015/04

US Classification:

119721000

Abstract:

An improved control station powered through an AC/DC converter is provided for use in conjunction with a buried boundary wire to provide a fence-free animal containment system. The control station has a transmitter unit that transmits a signal through the underground wire to determine the pet's boundary, and further includes a battery recharging docking station integrally formed therewith that receives the corresponding collar/receiver assembly worn by the animal when battery recharging of the receiver is necessary. Through the built-in docking station, the control station provides convenient collar battery recharging capability while efficiently using the same AC/DC converter unit that powers the control station transmitter unit.
