Definitions

  • the present invention relates to a personal protective device for repelling predators and more particularly pertains to driving away predators in an area with a sound generation device.
  • the present invention provides a solution to the above and other problems by enabling a simply designed, easy to construct, personally wearable, and inexpensive personal protective device that can selectively be worn either on a person's wrist or attached to any part of the human body or marine or land equipment, such as surfboards, flotation devices, and camping gear. It is, therefore, an object of the present invention to enable a personal protective device for repelling predators, and method of using the same, that avoids the disadvantages of the prior art. It is another object of the present invention to enable a personal protective device that is compact and portable. A related object is to enable a personal protective device that can be worn by a person, such as in a manner similar to a wristwatch.
  • It is another object of the present invention to enable a personal protective device comprising a sound generator for reproducing a sound known to repel predators; a piezoelectric speaker; and a power supply for supplying electrical energy to the sound generator and speaker.
  • a personal protective device is described for providing a marine and/or land transmission detraction and deterrence device designed to protect swimmers, scuba divers, surfers, hikers, hunters, campers and other individuals engaged in water and/or land activities from attacks by marine or land predators of human beings.
  • the device emits a high frequency pitch in varying sequential intervals that is easily heard, and more particularly is recognized, by sharks and/or by other targeted land and marine predators of humans.
  • a high pitch sound emitted by the device either is of natural sound recordings or of computer generated replica sounds preferably of pods of Killer Whales.
  • other sounds known or discovered to be recognizable by and effective in deterring sharks from menacing or attacking human beings may be utilized.
  • the sound emitted by the device can be selectively modified to target other marine and land predators.
  • FIG. 1 illustrates a block diagram of device having circuitry according to one embodiment of the present invention. Best Mode(s) for Carrying Out the Invention
  • a personal protective device of the present invention is constructed preferably in a portable, waterproof container 10.
  • a miniature circuit board 13 is disposed within the container 10, having a sound generator and control circuitry.
  • the sound generator produces digitally synthesized sounds of one or more feeding killer whales. Killer whale feeding sounds are recorded in the wild and the recorded sounds are converted to a digital sound signal.
  • the recorded killer whale sound is digitized, edited, and enhanced to produce digitally synthesized killer whale sounds.
  • the sound produced by the sound generator preferably is a digitally remastered, man-made sound recorded on a computer chip that is virtually identical to the natural recording.
  • the control circuitry is responsive to an input switch 16 that energizes such miniature circuit board 13.
  • Switch 16 has an enabled orientation for allowing the circuit board 13 to be electrically energized and a disabled orientation for preventing the circuit board 13 from being electrically energized.
  • the control circuitry directs the sound generator to produce the recorded sound.
  • the control circuitry directs the sound generator to replay the recorded sound as long as the circuit board remains energized.
  • the computer chip can have multiple sounds from different predators recorded thereon.
  • a means for selecting the desired sound to be produced by the sound generator is provided.
  • a piezoelectric speaker 19 is electrically connected to the sound generator on miniature circuit board 13.
  • the piezoelectric speaker 19 projects the sound output from the sound generator.
  • the projected sound should be of sufficient volume to be heard by a predator at a safe distance from the user. Such a safe distance varies with the predator being deterred.
  • the speaker generates a sound in the range of 120 to 190 decibels. Greater or lesser volume sound can be used as required by a particular application.
  • the piezoelectric speaker is commercially available and allows the device to be built in a small, compact container, and may be operated by a minimal power source, thus enabling the speaker to be incorporated in a personal protection device capable of being worn by a user.
  • One such manufacturer of piezoelectric devices is Piezo Systems, Inc. of Cambridge, Massachusetts.
  • Battery 22 supplies electrical energy for operation of the device.
  • the battery power will travel through switch 16 and energizes the miniature circuit board 13 that houses the sound generator containing the sound for broadcasting.
  • the sound generator begins transmitting the prerecorded sound through the piezoelectric speaker 19.
  • the battery is conventional in design and commercially available, such as Casio, Energizer, or Duracell wristwatch batteries.
  • the battery may be replaced when its electrical energy has been expended.
  • Mounted on the exterior of the waterproof container 10 may be two pushbuttons.
  • a first pushbutton 25 turns the device on by placing switch 16 in the enabled orientation.
  • a second pushbutton 26 turns the device off by placing switch 16 in the disabled orientation.
  • the personal protective device of the present invention is easily transportable, fully self-contained, and small enough to be worn by the user.
  • the device is constructed in a small, waterproof enclosure using piezoelectric speaker technology, which is the same type of technology used in small speaker devices, such as talking wristwatches and small personal alarms.
  • the piezoelectric speaker technology used in the device may utilize a natural recording of a natural predator of sharks.
  • the natural recording may comprise the sounds of a well-known pod of Killer Whales known as the R-Pod.
  • the device may serve to alert any shark or marine predator that killer whales are feeding nearby, causing the shark or marine predator to retreat.
  • a small watch battery powers the internal components of the device.
  • the protective device When activated, the protective device preferably emits a 4 to 10 kilowatt chirp through a piezoelectric speaker preferably ranging between 120 and 190 decibels to scare away a potential predator. It has been found that such decibel range is preferable for particularly transmitting the recordings of Killer Whales described above the desired distance of 30 to 100 meters.
  • the power and volume transmitted can be varied, so long as an overall transmission range of preferably between 30 and 100 meters is maintained.
  • the emitted sounds preferably last approximately 3-5 seconds and will be continuously repeated as long as the device is energized.
  • the amount of the recorded sound may be of any length provided it can be stored on a computer chip mounted on the miniature circuit board contained in the device.
  • such transmission preferably causes the sound to be projected underwater for a distance between 30 and 100 meters. The sound needs to be powerful enough to travel a sufficient distance through the water to reach its intended target for deterrence. The length of travel of the sound in water is dependent upon the power of the transmission and the water conditions.
  • the protective device is preferably constructed of a durable and waterproof outer shell and may be worn as a wrist/diving watch, or in any manner that will enable it to be attached to any part of the human body or marine or land equipment, such as surfboards, flotation devices, and camping gear.
  • the device can be modified using other natural sounds such as the sounds of bottle-nosed Dolphins, Sperm Whales, Humpback Whales and other like marine mammals and marine carnivores that are known to attack sharks or other marine predators. It can also be modified to use other sounds as deterrents to other predators of human beings. Such modification may be performed either by use of a different computer chip having a different recording or by using a variable selectable sound stored on a single chip. Similar piezoelectric speaker technology and interval sound transmission, sequential or otherwise, may be specifically designed to target other land and marine predators of human beings.
  • a personal protective device For the industrial application of a personal protective device, it is desirable to provide a piece of equipment that emits a sound designed to repel land and marine predators and that can be conveniently carried or worn by a person.
  • personal protective equipment for providing a marine and/or land transmission detraction and deterrence device designed to protect swimmers, scuba divers, surfers, hikers, hunters, campers and other individuals engaged in water and/or land activities from attacks by marine or land predators of human beings.
  • the device emits a high frequency pitch in varying sequential intervals that is easily heard, and more particularly is recognized, by sharks and/or by other targeted land and marine predators of humans.
  • the sound emitted by the device can be selectively modified to target a variety of marine and land predators.
