  • Impact test instrument
    Patent number: 4682490
    Abstract: A power-actuated instrument for the impact excitation of mechanical structures includes means for producing a single impact force of variable magnitude and self-contained integrated electronic means for detecting, conditioning, and limit testing of the electronic representation of the impact force so delivered.
    Type: Grant
    Filed: January 31, 1985
    Date of Patent: July 28, 1987
    Inventors: Roger A. Adelman, David A. Corelli
  • Method for quantitatively measuring a hearing defect
    Patent number: 4637402
    Abstract: A method is described for measuring the hearing deficit of a person preparatory to providing a hearing aid designed in accordance with analysis of the deficit, wherein frequency bands over which hearing level is unacceptable are determined, the bands are then shifted in harmonic sustaining manner to bands over which hearing level is acceptable, and thereafter over all frequency bands parameters necessary to shape, amplify, compress and adaptively filter background noise in continuously variable and adaptive fashion so as to produce an aurally optimized signal are adjusted and recorded.
