Abstract
Abstract A two hand operated instrument, for controlling electronic music synthesizers, video games and computers, capable of producing two independent control voltages, in addition to the signals produced by keyboards held in each hand, such additional control voltages actuated by rotating and telescoping the concentric tubes with respect to each other. In musical applications, the finger operated voltage signals may be used to select notes and the twist and telescope signals to control musical parameters, such as volume, pitch, timbre, pulse, width, spatial location, etc.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
In an electronic controller utilizing photovariable resistance, and outer cylinder provided with a first light source and first photoresistor and a second light source and second photoresistor, said photoresistors and light sources spaced and opposed within said outer cylinder, a variable density filter comprises a portion of a concentric inner cylinder, a first semi-cylinder of said filter varying in intensity along its circumference and movable between said first light source and first photoresistor, the second semi-cylinder of said filter varying in intensity along its length and movable between said second light source and second photoresistor, whereby rotating said filter varies the intensity of light upon said first photoresistor, and telescoping of said filter varies the intensity of light upon said second photoresistor.
Claim 2
Dependent Claim
122 words
In an electronic controller utilizing photovariable resistance, and outer cylinder provided with a first light source and first photoresistor and a second light source and second photoresistor, said photoresistors and light sources spaced and opposed within said outer cylinder, a variable density filter comprises a portion of a concentric inner cylinder, a first semi-cylinder of said filter varying in intensity along its circumference and movable between said first light source and first photoresistor, the second semi-cylinder of said filter varying in intensity along its length and movable between said second light source and second photoresistor, whereby rotating said filter varies the intensity of light upon said first photoresistor, and telescoping of said filter varies the intensity of light upon said second photoresistor.
Claim 3
Dependent Claim
37 words
The electronic controller of claim 1 in which said inner and outer cylinders are provided with stop means for limiting the rotational motion of said inner and outer cylinders with respect to each other to 180 degrees.
Claim 4
Dependent Claim
21 words
The controller of claim 1, in which the photovariable resistance is used to control musical parameters in an electronic musical instrument.
Claim 5
Dependent Claim
16 words
The controller of claim 1 in which the photovariable resistance is used to control videogame parameters.
