AI Technical Summary

Technical Problem

Conventional virtual fencing devices using high voltage electric shocks, auditory signals, and vibration face ethical concerns and effectiveness issues, as animals can become accustomed to the stimuli or withstand shocks to breach boundaries, raising the need for a more humane and effective method.

Method used

A virtual fencing device employing electrical muscle stimulation (EMS) with electrodes that induce muscle contraction using low voltage and current pulses, modulated for minimal discomfort, and a system that includes a microcontroller to activate electrodes based on device position relative to boundaries, utilizing time of flight trilateration and radiofrequency protocols for precise positioning.

Benefits of technology

The EMS-based system effectively guides animals without causing intense pain, addressing ethical concerns and enhancing the reliability and precision of boundary adherence.
