Abstract
Abstract A head positioning system including contact means placing the head in a controlled position which includes means for allowing controlled repeatable motion about at least one of three mutually perpendicular axes. Translational means along each axis and transducer means about each axis and on each of the translational means may also be provided.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A head positioning system for physically impaired persons including positioning means having x, y and z axes for placing the head in a controlled position which provides support for the head including means for preventing uncontrolled motion transitional of the head with respect to said system along the x axis and along the y and z axes after adjustment along the y and z axes, x axis pivot means connected to said positioning means for allowing enhanced, free flowing, non-resistive motion about said x axis.
Claim 2
Dependent Claim
85 words
A head positioning system for physically impaired persons including positioning means having x, y and z axes for placing the head in a controlled position which provides support for the head including means for preventing uncontrolled motion transitional of the head with respect to said system along the x axis and along the y and z axes after adjustment along the y and z axes, x axis pivot means connected to said positioning means for allowing enhanced, free flowing, non-resistive motion about said x axis.
Claim 3
Dependent Claim
17 words
The head positioning means of claim 1 including stop means for limiting motion around said x axis.
Claim 4
Dependent Claim
35 words
The head positioning system of claim 1 including y axis pivot means connected to said x axis pivot means for allowing enhanced free flowing, non-resistive motion about said y axis perpendicular to said x axis.
Claim 5
Dependent Claim
43 words
The head positioning system of claim 3 including translational means connected to the positioning means for translation along the y axis while said means for preventing uncontrolled linear translational motion in the y axis is temporarily disabled in order to perform said adjustments.
Claim 6
Dependent Claim
20 words
The head positioning system of claim 3 including means for immobilizing motion around one of said x or y axis.
Claim 7
Dependent Claim
23 words
The head positioning means of claim 3, including stop means for limiting motion around at least one of said x and y axes.
Claim 8
Dependent Claim
42 words
The head positioning system of claim 3 including z axis pivot means connected between said positioning means and said y axis pivot means for allowing enhanced, free flowing, non-resistive motion about said z axis perpendicular to said x axis and y axis.
Claim 9
Dependent Claim
54 words
The head positioning system of claim 3 including transducer means mounted to measure motion about at least one of said x, y or z axis pivot means for generating a signal proportional to the motion of the pivot means relative to the positioning means which may be used as a control or indicating signal.
Claim 10
Dependent Claim
23 words
The head positioning system of claim 7 including means for immobilizing motion around one or two of said x, y or z axes.
Claim 11
Dependent Claim
24 words
The head positioning means of claim 7 including stop means for limiting motion around at least one of said x, y or z axes.
Claim 12
Dependent Claim
43 words
The head positioning system of claim 7 including translational means connected to the positioning means for translation along the z axis while said means for preventing uncontrolled linear translational motion in the z axis is temporarily disabled in order to perform said adjustments.
Claim 13
Dependent Claim
18 words
The head positioning system of claim 11 including transducer means mounted to measure motion along said translational means.
