Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
62 words
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.
Claim 2
Dependent Claim
62 words
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.
Claim 3
Dependent Claim
28 words
The sensor of claim 1, wherein gate circuit means are connected electrically with said voltage-inducing means for changing its on-off state depending upon move-stop state of said ball.
Claim 4
Dependent Claim
35 words
The sensor of claim 2, wherein a discriminating signal generator is electrically connected with said gate circuit means, the former being modified in its operating condition depending upon said on-off state of said gate circuit.
Claim 5
Dependent Claim
32 words
The sensor of claim 3, wherein said signal generator comprises a flip-flop as an oscillator, the oscillating frequency of said flip-flop depending upon by the on-off state of said gate circuit means.
Claim 6
Dependent Claim
44 words
The sensor of claim 4 for attachment to a hunting dog, wherein said signal generator further comprises an oscillator of a predetermined frequency, in the range 2,000-3,000 Hz electrically connected with said flip-flop, for indicating whether the ball and hence the dog is moving.
Claim 7
Dependent Claim
66 words
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.
Claim 8
Dependent Claim
66 words
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.
Claim 9
Dependent Claim
65 words
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.
Claim 10
Dependent Claim
65 words
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.
Claim 11
Dependent Claim
