US Patent:

40513319, Sep 27, 1977

Filed:

Mar 29, 1976

Appl. No.:

5/671420

Inventors:

William James Strong - Provo UT
Edward Paul Palmer - Provo UT

Assignee:

Brigham Young University - Provo UT

International Classification:

G10L 100

US Classification:

179107R

Abstract:

A hearing aid system and method includes apparatus for receiving a spoken speech signal, apparatus coupled to the receiving apparatus for determining at successive intervals in the speech signal the frequency and amplitude of the largest formants, apparatus for determining at successive intervals the fundamental frequency of the speech signal, and apparatus for determining at successive intervals whether or not the speed signal is voiced or unvoiced. Each successively determined formant frequency is divided by a fixed value, greater than 1, and added thereto is another fixed value, to obtain what are called transposed formant frequencies. The fundamental frequency is also divided by a fixed value, greater than 1, to obtain a transposed fundamental frequency. At the successive intervals, sine waves having frequencies corresponding to the transposed formant frequencies and the transposed fundamental frequency are generated, and these sine waves are combined to obtain an output signal which is applied to a transducer for producing an auditory signal. The amplitudes of the sine waves are functions of the amplitudes of corresponding formants.

Abstract:

An internal combustion engine in which first and second elongate blocks of identical structure are axially aligned and held in longitudinally spaced relationship by a generally cylindrical connector. The first and second blocks cooperate to define a number of axially aligned cylinders, each of which has a double ended piston slidably mounted therein, and each of which piston supports a pair of cam engaging members. A drive shaft is rotatably supported in the first and second blocks, which drive shaft supports a force receiving cam that is engaged by the pairs of members on the pistons, with the cam situated within the confines of the connector. First and second circumferentially extending fuel intake chambers are defined in the first and second blocks, with each being fed fuel from opposite sides thereof, and force being sequentially applied to the pistons by exploding a fuel charge in first one end of each cylinder and then the opposite end thereof, and the pistons as they move in response to the explosion of the fuel charges imparting rotary motion of the cam to rotate the drive shaft. Coolant is discharged into opposite sides of the coolant chamber to more effectively cool the engine. Accessories are preferably disposed in a housing that is interchangeable with a forwardly disposed bullet nose shaped valve cover through which the drive shaft extends to a power take off.
