Abstract
Abstract An x- and y-axis translating apparatus independently translates the motion of a primary shaft in the x- and y-axis directions simultaneously to transducers which generate electrical signals representative of the motion of the primary shaft in the x- and y-axis directions. The apparatus may include button-activated switches for convenient activation with the thumb or forefinger, or other fingers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
An apparatus comprising: a primary shaft including distal and proximal portions, said proximal portion mounted on a rotational shaft to translate motion of the distal portion of the primary shaft in the x-axis direction to the rotational shaft, the primary shaft being coupled to a longitudinal shaft, and the longitudinal shaft having a camming device to translate motion of the primary shaft in the y-axis direction to the longitudinal shaft; the rotational shaft being mounted to rotate freely inside a housing and to translate motion of the primary shaft in the x-axis direction to an x-axis transducer; pin means for mounting said primary shaft on said rotational shaft, said pin means permitting said primary shaft to be rotated about an axis perpendicular to both said primary and rotational shafts; the longitudinal shaft being positioned inside of and coextensive with the rotational shaft to rotate with the rotational shaft and to move longitudinally within the rotational shaft to translate motion of the primary shaft in the y-axis direction to a y-axis transducer; and a peg attached to the longitudinal shaft that moves within a first slot of the primary shaft to translate motion of the primary shaft in the y-axis direction to the longitudinal shaft.
Claim 2
Independent Claim
204 words
An apparatus comprising: a primary shaft including distal and proximal portions, said proximal portion mounted on a rotational shaft to translate motion of the distal portion of the primary shaft in the x-axis direction to the rotational shaft, the primary shaft being coupled to a longitudinal shaft, and the longitudinal shaft having a camming device to translate motion of the primary shaft in the y-axis direction to the longitudinal shaft; the rotational shaft being mounted to rotate freely inside a housing and to translate motion of the primary shaft in the x-axis direction to an x-axis transducer; pin means for mounting said primary shaft on said rotational shaft, said pin means permitting said primary shaft to be rotated about an axis perpendicular to both said primary and rotational shafts; the longitudinal shaft being positioned inside of and coextensive with the rotational shaft to rotate with the rotational shaft and to move longitudinally within the rotational shaft to translate motion of the primary shaft in the y-axis direction to a y-axis transducer; and a peg attached to the longitudinal shaft that moves within a first slot of the primary shaft to translate motion of the primary shaft in the y-axis direction to the longitudinal shaft.
Claim 3
Dependent Claim
53 words
The apparatus of claim 1 wherein a lateral shaft coupled to the longitudinal shaft on one end of said lateral shaft and to a y-axis cam on the other end of said lateral shaft is positioned between two springs, to bias the primary shaft toward its initial, center position in the y-axis direction.
Claim 4
Dependent Claim
41 words
The apparatus of claim 1 wherein at least one of said transducers is a potentiometer including a slide contact, the slide contact being mounted to generate an electrical signal representative of the motion of the primary shaft in the y-axis direction.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 wherein a lateral shaft is coupled to the rotational shaft on one end and an x-axis cam on the other end to translate motion of the primary shaft in the x-axis direction.
Claim 6
Dependent Claim
33 words
The apparatus of claim 1 wherein the x-axis transducer is a potentiometer including a slide contact for providing an electrical signal representative of the motion of the primary shaft in the x-axis direction.
Claim 7
Dependent Claim
49 words
The apparatus of claim 1 wherein two plates are mounted on the rotational shaft and are connected to two springs to bias the primary shaft toward its initial, center position in the x-axis direction and to limit the range of motion of the primary shaft in the x-axis direction.
