Animal containment system
First Claim
1. An animal confinement system comprisinga transmitter for transmitting near infrared energy coded with pulses having first and second frequencies anda receiver to be worn by the animal for receiving the transmitted near infrared energy coded with said pulses having said first and second frequencies, said receiver includinga sounder for producing a warning tone,transformer means for providing a high voltage low energy shock,first means for operating said sounder when near infrared energy is received coded with pulses having said first frequency, said operating means having first and second one shots defining a first digital bandpass filter,second means for operating said transformer means when near infrared energy is received coded with pulses having said second frequency, said second operating means having third and fourth one shots defining a second digital bandpass filter,said first bandpass filter being selected so that said pulses having said first frequency will be detected while said pulses having said second frequency will not be detected, andsaid second bandpass filter being selected so that said pulses having said second frequency will be detected while said pulses having said first frequency will not be detected.

Abstract
An animal containment system is disclosed wherein the contained animal wears a receiver which receives first and second codes in the form of frequencies which are defined in adjacent curtains of near infrared or the like light established by a transmitting device. One pair of one shots detects one frequency and a second pair of one shots detects a second frequency. When the warning frequency is detected a sounder continuously operates and when the second frequency is detected a transformer is intermittently operated to shock the animal and the sounder is intermittently operated. The transformer can be operated in three modes: high power, low power or disconnected.

5. An animal confinement system comprising:
- a transmitter for transmitting a first code in one zone and a second code in an adjacent second zone, a receiver to be worn by the animal for receiving near infrared energy coded with said first and second codes, said receiver including
a sounder, transformer means for providing a high voltage low energy shock, means for continuously operating said sounder when near infrared energy is received having said first code, said operating means including a first transistor, and a comparator having an output controlling the operation of said transistor, an oscillator having an output operating said transformer means when near infrared energy is received having said second code, and means for connecting the output of said oscillator to the output of said comparator for intermittently operating said sounder when near infrared energy is received having said second code. - View Dependent Claims (6, 7, 8, 9)
