Sound Generating System For A Keyboard

US Patent:
46947256, Sep 22, 1987
Filed:
Sep 3, 1985
Appl. No.:
6/772224
Inventors:
Daniel B. Seevers - Cambridge OH
John J. Rohulich - Cambridge OH
Assignee:
NCR Corporation - Dayton OH
International Classification:
G01H 146
US Classification:
84 127
Abstract:
A method and apparatus for establishing the volume level of a tone generator associated with a keyboard in which the tone generator will output a click tone when each key on the keyboard is actuated. In establishing the volume level of a click tone, the keyboard is put into a volume setting mode by the actuation of two key members of the keyboard. The subsequent actuation of each key member will produce a different volume level of the click tone. The actuating of a key member results in the storing of a count in a storage member. The storage member is then downcounted until it reaches zero. Upon reaching the count of zero, processing means generates a pulse train in which the pulse width is determined by the time it takes for the storage member to count down to zero.

Speaker Volume Control Apparatus And Method

US Patent:
47979321, Jan 10, 1989
Filed:
Nov 23, 1987
Appl. No.:
7/124329
Inventors:
John J. Rohulich - Cambridge OH
John B. Keys - Cambridge OH
Assignee:
NCR Corporation - Dayton OH
International Classification:
H04N 704
G01H 146
G08B 300
US Classification:
381104
Abstract:
Apparatus and method for establishing and changing the volume level of a tone generator which may be used in connection with auditory feedback in a point of sale terminal or other business machine include a microprocessor having a timer with two settable registers which can be set to establish the duty cycle of a signal, an inverting buffer coupled to the timer output, an integrating circuit to which the signal from the buffer is applied, a transistor driver for a speaker to which the integrated signal is applied, and the speaker, the volume of the tone of which may be changed by altering the relative counts of the two timer registers.
