Abstract
An animal confinement system comprising an emitter for transmitting coded near infrared energy, a receiver carried by an animal to be contained for receiving the transmitted coded near infrared energy, including an infrared receiving diode and, a comparator for conditioning the output of the infrared receiving diode. A predetermined threshold is established for the comparator which will cause the output of the comparator to go low when the output of the infrared receiving diode is received.
Claims10
An animal confinement system comprising
- means for transmitting coded near infrared energy,
- means to be carried by an animal to be contained for receiving said transmitted coded near infrared energy, including
- infrared receiving diode means,
- a comparator for conditioning the output of said infrared receiving diode means, and
