Patent Number Title Of Patent Date Issued
6731769 Upper audio range hearing apparatus and method May 4, 2004
A system and method upper auditory frequency range hearing. A speech signal is filtered, and then modulated to an upper auditory frequency range. The modulated signal is then provided to a transducer, which causes a vibration in the ear canal, the head or the neck of a user, which is
6394969 Tinnitis masking and suppressor using pulsed ultrasound May 28, 2002
A system and method for tinnitus masking. Ultrasound noise is provided to a head of a patient as a vibration by way of a transducer, to thereby stimulate the auditory cortex. Once stimulated, the auditory cortex will suppress tinnitus. The ultrasound noise may be provided as an ultrasoun
6388949 Marine turtle acoustic repellent/alerting apparatus and method May 14, 2002
A turtle alerting system and method utilizes an acoustic signal that may be provided in a first, low frequency range, a second, mid-frequency range, or a third, high frequency range. One or more of those acoustic signals may be accompanied and/or modulated by either an ultrasonic signal
6368267 Stapedial-saccular strut and method April 9, 2002
A system and method for an auditory inner ear prosthesis. A strut connects the medial surface of the stape footplate with the wall of the saccule. The strut spans the 1.5 mm vestibule between the saccule and the stapes. The strut is a synthetic elastic connector constructed of biocompati
6250255 Methods and apparatus for alerting and/or repelling birds and other animals June 26, 2001
An external stimuli is provided that alerts animals to danger and/or repels the animals from certain areas. More specifically, the system and method of the present invention uses an external stimuli, such as, for example, pulsing microwaves, vibration or supersonic sound waves, in order
5047994 Supersonic bone conduction hearing aid and method September 10, 1991
A supersonic bone conduction hearing aid that receives conventional audiometric frequencies and converts them to supersonic frequencies for connection to the human sensory system by vibration bone conduction. The hearing is believed to use channels of communications to the brain that
4982434 Supersonic bone conduction hearing aid and method January 1, 1991
A supersonic bone conduction hearing aid that receives conventional audiometric frequencies and converts them to supersonic frequencies for connection to the human sensory system by vibration bone ocnduction. The hearing is believed to use channels of communications to the brain that
