Anatomic Or Prosthetic Relation Patents (Class 181/126)
  • Patent number: 11051116
    Abstract: Methods and devices for measuring vibration of an implanted driven vibrating elongate body coupled to a bone of the middle ear, for example using an accelerometer coupled to the vibrating body. The measured vibration can be taken during implantation and long again after implantation to check for possible decoupling, disease, or additionally impeded vibratory driving of the middle ear bone. An accelerometer signal can be converted to a displacement value and used to check for an under impeded or over impeded vibratory body. An implanted device can be used to periodically check the vibration of the vibratory body. Methods and devices can be used in conjunction with implanted devices which receive vibratory signals from a middle ear bone and use the signals to drive a disarticulated middle ear bone closer to the ear drum.

  • Patent number: 10716532
    Abstract: A protective case in two parts (L, R) interconnected by a flexible top wall (28) acting as a hinge and a closure spring. Opposed jaws (32, 34) in the two respective parts (L, R) hold a stethoscope chestpiece (40) within the case, and protect its diaphragm (43) behind a separable (24) front wall (22). The jaws have insertion ramps (33A, 35A) that open the jaws upon insertion of the chestpiece, a retention portion (33C, 35C), and removal ramps (33D, 35D) that open the jaws upon removal. A chest piece is inserted by pushing it into the insertion ramps. It is removed by pulling it outward against the removal ramps. This protects the chestpiece from damage in a medical equipment bag to which the case may be attached by a lanyard (37) for quick location. A back wall (23) may protect a second diaphragm (45) of the chestpiece.

  • Publication number: 20030034198
    Abstract: A dilatant circumaural hearing protection earcup soft seal is disclosed. The design of the instant invention is predicated on the theory that the primary function of an effective earcup soft seal is to hold the earcup it is attached to stiffly against the user's head. Experimental evidence shows that an earcup is “pumped” in response to acoustic pressure and reconstructs the acoustic signal inside the earcup as a diaphragm, even though very little noise may pass directly through the earcup itself. The soft seals of the instant invention utilize the dilatant property of some materials to provide a soft seal that conforms slowly and comfortably to a user's head but is stiff under the influence of high shear rate acoustic pressure.

    Abstract: A system and a method for remote monitoring of a designated user utilize an integrated scale that is able to measure the body weight of a current user and determine whether the current user is the designated user. The identification of the current user is accomplished by measuring a preselected length of the current user by reflecting sound waves at location(s) that defines the preselected length and comparing the measured length to a corresponding length of the designated user that is stored in the integrated scale. When the current user is identified as the designated user, the integrated scale transmits the measured body weight to a remote monitoring device. The preselected length may be the distance from the bottom of a foot to the knee joint. Alternatively, the preselected length may be the length of a tibia or femur, or the skeletal height.

  • Patent number: 4685448
    Abstract: A vocal tactile feedback apparatus and method for use in the treatment of stuttering and other speech or hearing abnormalities is disclosed. A microphone and amplifier are utilized to produce and amplify an electronic signal responsive to vocal utterances spoken within a known range of the microphone. The amplified signal is then delayed by a suitable delaying circuit for a desired time interval and is then transmitted to an electro-mechanical transducer attached to the outer surface of the laryngeal or glottis region of the neck of a user. The transducer then transforms the amplified delayed signal into a mechanical vibration to provide delayed vibrotactile feedback of the vocal utterances whether spoken by the user or by others. A unique transducer assembly for use in the apparatus and method is disclosed.

  • Patent number: 4498461
    Abstract: The present invention refers to a coupling intended for mechanical transmission of sound information from a vibration generating apparatus as a transmitter to the skull of a person with damaged hearing, including a first coupling part, for example directly anchored to the skull, and a second coupling part attachable to it and mounted on the sender, whereby at least one vibration-transmitting surface is formed between the coupling parts.

  • Patent number: 4183422
    Abstract: A communications device for use under water by a human speaker. A tubular base member has a mouthpiece located at one open end thereof and an inflatable air bag mounted about another open end thereof. In use, the speaker places the mouthpiece around his mouth to form an air seal therebetween and blows into the air bag to partially inflate it. When so inflated, the speaker talks into the device with voiced sounds being transmitted to the surrounding water through suitable transmitting means attached to the base member, preferably the air bag itself. During talking, the air bag receives and returns the air used by the speaker, thereby effectively preventing the escape of air bubbles from the device which otherwise interfere with communications. The air bag is preferably an elongated, flexible balloon which can be stretched into an extended position when speaking into it under water.

  • Patent number: 4174155
    Abstract: A sponge sound absorbing article for placement on the side frames of eyeglasses for workers employed in very noisy environments. The sound absorbing article eliminates any sound gap between the sides of the eyeglass frames and conventional earmuffs to protect the ears from sustained exposure to dangerous noise levels.

  • Patent number: 4107775
    Abstract: An apparatus and method suitable for automatic machine interrogation of individuals for identifying or analyzing persons such as those seeking admittance to secure areas or seeking an extension of credit. Physical vibration wave energy is applied by a signal generator and transducer to the person's body at a selected point such as the finger tips. The frequency and/or the time function of force and/or motion parameters at the driving point of the body are then detected and stored. Comparison of a previously known function with a subsequently measured function to determine whether they are within preselected tolerances permits a machine decision whether the functions represent the same person.
