Embodiment Construction

[0018] Referring to FIG. 1 , the personal protection device of the present invention is preferably constructed in a portable waterproof container 10 . A small circuit board 13 is placed inside the container 10, with a sound generator and control circuitry. In a first embodiment of the invention, a sound generator generates digitally synthesized sounds of one or more feeding orcas. The feeding sounds of orcas were recorded in the wild, and the recorded sounds were converted into digital sound signals. Recorded orca sounds were digitized, edited and enhanced to produce digitally synthesized orca sounds. The sound produced by the sound generator is preferably a digitally remastered artificial sound recorded on a computer chip that is virtually identical to a natural recording. About 5 to 10 seconds of sound are recorded on a computer chip.

[0019] The control circuit is responsive to an input switch 16 that supplies power to such a small circuit board 13 . The switch 16 has ...

Abstract

A personal protective device (and method of its use) comprising a marine and 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 sharks as well as from attacks from other marine and land predators of human beings. The device emits a high frequency pitch in varying sequential intervals that is easily heard and recognized by sharks and/or by other targeted land and marine human predators. The personal protective device comprises sound generator means for reproducing a sound known to repel predators; a piezoelectric speaker; and a power supply for supplying electrical energy to the sound generator means and speaker contained in a waterproof package.

Description

technical field [0001] This invention relates to personal protective equipment for repelling predators and, more particularly, to the use of sound generating devices to repel predators in an area. Background technique [0002] Swimmers, scuba divers, hikers, hunters, and campers sometimes find themselves in environments with land or sea animals known to prey on humans. While making noise on land is usually enough to repel some terrestrial predators, the splash and motion of underwater activities can attract some marine predators, such as sharks. [0003] Various efforts have been made in the past to attempt to control land or sea animals using acoustic devices. Generally, the devices designed and used to date for repelling land and sea animals have consisted of fixed or ship-borne units using various mechanisms to generate sound or vibration which it is hoped can be Repel or control the behavior of these land or sea animals, including the following: [0004] US Patent No....
