Abstract
A humane, pain-free method of animal training includes interrupting the animal's vision to deliver a training stimulus. A lens having an electro-optic shutter is placed within the animal's field of vision. The shutter is open and does not obstruct or interrupt the animal's vision while the animal exhibits desirable behavior. The shutter is closed and interrupts the animal's vision to deliver a training stimulus as needed. The closed shutter is re-opened to remove the training stimulus and continue training.
Description




FIELD OF THE INVENTION




The invention relates to an animal training method and an apparatus for carrying out the method.




BACKGROUND OF THE INVENTION




There are many animal training methods in use today. Conventional training methods apply some form of unpleasant or negative stimulation, such as a loud or uncomfortable sound, to train the animal. Negative stimulation is not very effective when used alone and so it is usually coupled with painful stimulation as a training reinforcement. Typical forms of painful simulation include vibrations, electric shock or even choking the animal. These stimuli rely on pain and fear to teach the animal desired behavior. Such painful stimulation can confuse the animal, break the animal's spirit and is unsuitable for many training regimes. In inexperienced hands such training can even approach animal cruelty.




Thus there is a need to replace conventional animal training methods with an improved, more humane training method. The improved method should not apply negative or painful stimuli, nor rely on pain and fear to teach desired animal behavior. The method should be usable in a wide variety of animal training regimes.




SUMMARY OF THE INVENTION




The invention is a humane, pain-free animal training method. The method does not apply negative or painful stimuli to the animal and does not rely on pain or fear to teach desired behavior. The method may be used to train dogs, horses and other trainable animals, and is usable in a wide variety of animal training regimes.




It has been found that a temporary interruption of an animal's vision can be used as a training stimulus. During training, the animal's vision or field of view is temporarily obstructed or interrupted. The animal may at first be initially confused, but quickly becomes accustomed to having its vision interrupted. The interruption is not painful and does not scare the animal.




The steps of an animal training method having features of the present invention include attaching a light valve to the animal within the animal's field of vision. A light valve is a device that has an open, transparent state which allows light transmission through the valve and a closed, opaque state which substantially reduces or eliminates light transmission through the valve. The valve is kept open and does not obstruct or interrupt the animal's vision while the animal exhibits desirable behavior. The light valve is closed and obstructs or interrupts the animal's vision to deliver a training stimulus. The light valve is re-opened to remove the stimulus and restore the animal's vision for continued training.




In preferred embodiments of the method the step of opening or closing the light valve includes applying a voltage differential across an electro-optic material. Such materials change between opened and closed states in response to an applied voltage differential across them. Conventional electro-optic materials include liquid crystals and light polarizing filters.




An animal training apparatus for practicing the method of the present invention includes spectacles having a lens and an attachment member for holding the lens in the field of view of the animal. The lens preferably includes an electro-optic shutter, that is, a shutter formed from an electro-optic material. A voltage source generates a voltage differential and circuitry connected between the voltage source and the shutter applies the voltage differential to open or close the shutter. The circuitry includes a switch that selectively opens or closes the circuit to enable the trainer to apply the training stimulus when needed. The switch can be actuated by a remote control device held by the trainer.




Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings illustrating animal training apparatus of the present invention, of which there are three sheets of two embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIGS. 1-3

illustrate a first embodiment animal training apparatus


10


in accordance with the present invention. The apparatus


10


is shown on a dog, it being understood that the apparatus can be readily adapted for training other breeds of dogs and other trainable animals.




Animal training apparatus


10


includes spectacles


12


with a pair of lenses


14


,


16


in front of the dog's left and right eyes respectively. The spectacles include an attachment member


18


holding the lenses in position within the dog's field of view. The attachment member


18


includes a frame


20


housing the lenses. In the illustrated embodiment the frame


20


seals the outer periphery of the eyes so that the dog's entire field of vision is defined by the lenses. An adjustable collar


22


fastens the spectacles securely about the dog's neck. A pair of lens straps


24


extend from the collar to opposite sides of the frame


20


and hold the frame in place against the dog's face. The lens straps or frames may also include adjustment features to position the lenses on different sizes or breeds of dog.




The lenses


14


,


16


are each made from a liquid crystal material that forms an electro-optic light valve or shutter


26


(see FIG.


3


). The shutter can switch between an open, transparent state and a closed, opaque state by applying a voltage differential across the material. Preferably the shutter is in a transparent state when no voltage differential is applied so that the shutter is normally open. The liquid crystal material is conventional and will not be described in further detail. A control circuit


28


electrically connects both lens shutters


26


with a battery or voltage source


30


to close the shutters.





FIG. 3

illustrates in schematic form the control circuit


28


extending to the lens


14


, it being understood that the voltage differential is applied and removed from the lenses


14


,


16


simultaneously. The circuit


28


includes a normally open switch


32


that closes to complete the circuit. When the switch is closed the circuit applies the voltage differential generated by voltage source


30


across the shutters.




The switch


32


is controlled by a control relay


34


operatively connected to an antenna


36


. A remote control device


38


transmits a microwave radio signal that is received by the antenna to actuate the relay and close the switch. The remote control


38


shown is separate from and not physically connected to the other components of the animal training apparatus. In other possible embodiments the control relay could be actuated by sound waves, infrared light or the like transmitted by the remote control


38


. Alternatively, the remote control device may be physically connected to the control relay by a signal cable


40


shown in dashed lines in FIG.


3


. The cable


40


would preferably be incorporated into a leash attached to the collar to maintain physical control of the dog during a training session.




The voltage source


30


, antenna


36


and other parts of the circuit


28


are housed in or mounted on a housing


42


attached to the collar


22


. The circuit extends from the housing


42


to the shutters through the collar and lens straps.




Operation of the animal training apparatus


10


in carrying out is the method of the present invention will now be described. The training apparatus


10


is fitted to the dog with the lenses


14


,


16


within the dog's field of vision as shown in FIG.


1


. The lens shutters shown in the figure are in their open, transparent state and do not obstruct the dog's field of vision.




A training session is then conducted with the dog, with the trainer holding the remote control


38


. The shutters remain open and do not obstruct the dog's vision while the dog exhibits desirable behavior. When it is necessary to deliver a training stimulus, the shutters


26


are closed by the trainer using the remote control


38


.

FIG. 2

illustrates the animal training apparatus


10


with the shutters of the lenses


14


,


16


closed. The closed shutters obstruct and interrupt the dog's vision to deliver the training stimulus. The shutters are then reopened to remove the training stimulus and restore the dog's vision for continued training.




In the illustrated embodiment the remote control device includes a push button


44


which is pressed to emit the radio signal closing the shutter and pressed again to stop the signal transmission and open the shutter. The control relay


34


is responsive to the presence or absence of the radio signal and enables the trainer to control the length of time the training stimulus is applied. In other possible embodiments the control relay could close the lens shutters for a set time to deliver the training stimulus for a predetermined time period. Other control circuits or timing arrangements could be used.





FIGS. 4 and 5

illustrate a second embodiment animal training apparatus


50


in accordance with the present invention. The illustrated apparatus


50


is adapted to be worn on a dog, but could be readily adapted for use with other animals.




The apparatus


50


includes spectacles


52


having a pair of lenses


54


,


56


in front of the dog's left and right eyes respectively and a hood-like attachment member


58


holding the lenses in position within the dog's field of view. To better illustrate how the spectacles fit the dog, the dog's eyes and forehead behind the spectacles are shown in

FIGS. 4 and 5

.




The attachment member


58


includes a frame


60


having a pair of flexible lens shrouds


62


, each shroud housing a lens


54


or


56


. Each shroud


62


surrounds one eye and limits the eye's field of vision to such lens. The shrouds


62


are carried in a flexible fabric goggle


64


attached to a stiff skullcap


66


that fits over the top of the dog's head. The skullcap


66


has an extension


68


that extends downwardly between the dog's eyes between the lens shrouds. A pair of chin straps


70


extend from the sides of the goggles and secure the goggle to the dog's head. The ends of the chin straps join together by a hook and loop fastener (not shown) and fit snuggly beneath the dog's lower jaw.




The attachment member


58


includes an adjustable collar


72


that fits around the neck of the dog. A pair of elastic goggle straps


74


extend from each side of the goggle


64


to the front of the collar and hold the goggle fabric taut. The skullcap


66


is attached to the rear of the collar


72


by primary and secondary skullcap straps


76


,


78


respectively. The primary skullcap strap


76


is looped through the back of the collar and is secured by a hook and loop connection


80


. The secondary strap


78


overlies a rearward extending tongue


84


on the rear of the skullcap


68


and extends towards the strap tongue


82


. The straps


76


,


78


and tongue


82


are preferably connected to one another by hook and loop fasteners to permit adjustment of the length of the straps as needed.




The lenses


54


,


56


are each made from a pair of crossed polarizer material that forms an electro-optic light valve or shutter which operate like the shutters


26


. Each polarizer allows only light polarized in one plane to be transmitted through the lens when a voltage differential is applied. A lens


54


,


56


is made from a pair of polarizers arranged with perpendicular polarization planes. The polarizers cooperate with each other and block light transmission through the lens when actuated. The cross polarizers can be formed from a liquid crystal material as previously described.




A control circuit and batteries (each not shown) like the circuit


28


and voltage source


30


applies the voltage differential to the lenses. The batteries and control circuitry are housed in an enclosure or housing


86


formed in the collar. The collar can also mount an antenna (not shown) for actuation of the lens shutters by a remote control device like the device


38


.




Although both illustrated embodiments


10


,


50


have separate lenses for the animal's left and right eyes, in other embodiments the apparatus could include just one lens which is in the field of vision of both eyes.




The shutters of the illustrated embodiments stop transmission of substantially all light through the lens when closed. In other possible embodiments the light valves could allow some transmission of light when in the closed or opaque state. The light valves would block sufficient light to be perceived as a vision interruption by the animal and thereby deliver a training stimulus.




Examples of conventional training regimes and how such training regimes can be adapted to the method of the present invention are described next. These examples illustrate the wide adaptability of the invention and are not intended to limit the scope of the invention. The method and apparatus of the present invention are readily adaptable to the training of dogs, horses and other animals, and may be used in other training regimes.




EXAMPLE 1




“Whoa” Command Training




“Whoa” is the command for animal training. It is an integral part of most training regimens. The command starts the training session and terminates the session, and is a part of almost every new command sequence.




The whoa command is both corrective and protective. The animal must respond to the command to stop undesirable behavior or behavior which could even harm the animal. An old adage among dog trainers is “when the whoa command is given, a properly trained dog stops in mid-air.”




Training an animal the whoa command using a negative stimulation method can, in some circumstances, harm the animal. The animal does not yet know the desired behavior, and negative stimulation applied when an animal is unsure of what to do can break the animal's spirit and render the animal untrainable. The pain and fear can even make the animal unfit as even a simple house pet.




When training an animal the whoa command using the method of the present invention, the animal does not experience negative stimulation, even when the animal has not yet learned the proper response to the command. The animal can be taught the whoa command without the risk of breaking the animal's spirit.




The interruption of the animal's vision also has the added benefit of stopping undesirable behavior without pain. The animal is thereby safer because the vision interruption will cause the animal to stop behavior that could cause it harm.




EXAMPLE 2




Puppy Training




When training a puppy, the puppy is conventionally placed on a bench and connected to an overhead wire. After obedience on the bench is established, the same commands must be taught on the ground and then reinforced around birds or game. The need to re-teach commands wastes time and puts a lot of pressure on the puppy. The pressure may be severe enough to have a deleterious effect on the puppy's spirit, and may even make the puppy unsuitable as a pet.




When trained in accordance with the method of the present invention, the puppy can be taught immediately on the ground. The puppy does not have to be initially restrained by a wire. The puppy will receive a much freer, less physically restrained introduction to working with the owner or trainer. The puppy's spirit will remain positive and the puppy will not become people-shy as a result of harsh training.




EXAMPLE 3




Herding or Chase Instinct of Dogs




Many dogs instinctively have the urge to herd or chase. Chasing other animals or vehicles is undesirable and often dangerous. Conventionally, drastic steps are taken to control such instinctive behavior. These included the use of an electric collar or squirting ammonia into the dog's face from a moving vehicle. The dog can now be stopped safely and trained painlessly by the animal training method of the present invention to modify the instinct to herd or chase.




EXAMPLE 4




Training Retrievers




Training a dog to retrieve game is taught in its first stages in a “hands-on” fashion. The trainer then moves farther and farther away from the actual retrieving exercise. The trainer's goal is to have the dog wait for the command to retrieve. But the dog has a natural instinct to retrieve the game immediately, and often painful stimuli would be applied to teach the dog to retrieve on command. This may cause the dog to “blink” game and go away from it for fear of receiving such painful, negative stimulation.




Vision interruption in accordance with the method of the present invention lends itself well to training retrievers. The vision interruption can keep the dog stationary until the fetch command is given and vision is restored. It can also be useful in shortening the time needed to teach multiple or directional retrieving in pointing and retrieving dogs.




EXAMPLE 5




Street Control




An animal training apparatus for the training method of the present invention also has value for street control of the animal. A dog is typically fitted with a muzzle and walked on a leash among pedestrians. If the dog breaks free of the leash, the dog could run into traffic or jump on a pedestrian. If the dog slips the muzzle, the dog might bite. With the apparatus of the present invention, the dog's vision can be interrupted to stop the dog until control of the dog is regained.




The training method of the present invention can be combined with other training stimuli, as for example, giving the animal a positive reinforcement after exhibiting desired behavior.




The animal training method and apparatus of the present invention enable the trainer to train an animal without painful or negative stimulation. If an animal can be trained without pain or fear, both the animal and the trainer will be happier. The animal will be well trained and well treated, and its spirit will remain whole. The trainer will not be even unintentionally cruel to the animal.




While I have illustrated and described preferred embodiments of my invention, it is understood that these are capable of modification, and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and alterations as fall within the purview of the following claims.
