Abstract
The sensor disclosed attaches to the neck of a hunting dog for determining its physical behavior thereof. It includes a sensor proper having a movable ball confined in a closed space. A voltage producing device at least partly defines the walls of the closed space. A gate circuit is electrically connected with the voltage producing device. Further, a discriminating signal generator is electrically connected with the voltage producing device so the dog's master can determine the dog's behavior.
Claims10
An omnidirectional move-stop sensor, comprising a movable ball placed within a confined space and voltage-inducing means at least partly defining a wall of said space for generating a voltage varying with impact on collision of said ball with said wall, said wall including a material generating a voltage on impact, said ball being freely movable along at least two dimensions during operation.
An omnidirectional move-stop sensor, comprising a movable ball placed within a confined space and voltage-inducing means at least partly defining a wall of said space for generating a voltage on collision of said ball with said wall, said confined space being a hollow structure having a plurality of flat walls, one of said walls including a piezoelectric element having an inside electrode and an outside electrode.
An omnidirectional move-stop sensor, comprising a movable object placed within a confined space, and signal-inducing means at least partly defining a wall of said space for generating an electrically sensible signal varying with impact collision of said object with said wall, said wall including a material generating an electrically sensible signal of impact, said object being freely movable along at least two dimensions during operation.
