Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A method of testing the motor skills retained by persons with impaired brain function which comprises having said person pass a hand held electrically conducting stylus down the length of each of a series of slots in a planar solid, said slots having a variety of geometric shapes of increasing complexity, but having a width not much bigger than said stylus, each of said slots further having electric contacts at each end connected to an electrically activated timing means, said slots also having an electrically conducting edging connected to means for effecting an alarm at each contact of the stylus with said edging and to means for recording the number of said contacts in the passage down each slot.
Claim 2
Independent Claim
119 words
A method of testing the motor skills retained by persons with impaired brain function which comprises having said person pass a hand held electrically conducting stylus down the length of each of a series of slots in a planar solid, said slots having a variety of geometric shapes of increasing complexity, but having a width not much bigger than said stylus, each of said slots further having electric contacts at each end connected to an electrically activated timing means, said slots also having an electrically conducting edging connected to means for effecting an alarm at each contact of the stylus with said edging and to means for recording the number of said contacts in the passage down each slot.
Claim 3
Dependent Claim
17 words
The method of claim 1 in which said alarm means is an electrically activated noise producing device.
Claim 4
Dependent Claim
14 words
The method of claim 1 in which said alarm means is an electric lamp.
Claim 5
Dependent Claim
22 words
The method of claim 1 in which said alarm means includes both an electrically activated noise producing device and an electric lamp.
Claim 6
Independent Claim
29 words
A device for testing the motor skills of a person with impaired brain function which comprises, in combination (a) a planar solid having plurality of slots cut out thereof;
Claim 7
Independent Claim
29 words
A device for testing the motor skills of a person with impaired brain function which comprises, in combination (a) a planar solid having plurality of slots cut out thereof;
Claim 8
Dependent Claim
106 words
(b) said slots being shaped in a variety of widths and geometric shapes of differing complexity varying from straight lines to curves, angles and circles; (c) said slots having electric contacts at either end connected to the start and stop mechanism of a timing means; (d) said slots having all the edges lined with an electrically conducting material connected to at least one means for effecting an alarm and with an electrically activated counting means; and (e) a hand held electrically conducting stylus connected electrically to said alarm means such that each contact with said electrically conducting slot lining activates said alarm and said counting means.
Claim 9
Dependent Claim
106 words
