Abstract: A system for training animals includes a hand-held device and a remote device, where the remote device applies a stimulus when a user presses a button or trigger on the hand-held device. The amount of pressure applied is measured by a pressure sensitive transducer and transformed into proportional transducer signals. These transducer signals are transmitted to the remote device, which then applies a stimulus to an animal being trained. The amplitude of the applied stimulus corresponds to the amplitude of the transducer signals; a trainer can thus precisely control the intensity of the stimulus by applying and relieving pressure on the button. The type of stimulus applied is controlled based on the position of a rotary switch on the hand-held device. Sensor data generated by specialized sensors in the remote device may be transmitted to the hand-held device to provide the user with sensory feedback.

The invention allows the user to control the initial training while providing the flexibility and consistency of an automated training reinforcement process. After the user-controlled initial training process is completed, location devices can be physically positioned anywhere a desired behavior requires modification or reinforcement.
