Independent Claim
69 words
A method for evaluating foot borne motion in an individual comprising: applying footwear to at least one foot of said individual having means for registering predetermined movement of said foot relative to an axis of reference during foot borne motion; causing said individual to engage in said foot borne motion; and detecting said predetermined movement of the foot relative to said axis of reference during said foot borne motion.
Claim 2
Independent Claim
69 words
A method for evaluating foot borne motion in an individual comprising: applying footwear to at least one foot of said individual having means for registering predetermined movement of said foot relative to an axis of reference during foot borne motion; causing said individual to engage in said foot borne motion; and detecting said predetermined movement of the foot relative to said axis of reference during said foot borne motion.
Claim 3
Independent Claim
91 words
An apparatus for evaluating foot borne motion in an individual comprising a support member, footwear mounting said support member thereon and adapted to attach said support member to a foot of said individual, means borne by the apparatus for detecting predetermined movement of the foot during said foot borne motion, and wherein said footwear has a mounting assembly on a lower portion thereof operable releasably to mount said support member on said lower portion of the footwear so as to permit support members of different operational capabilities to be mounted thereon.
Claim 4
Independent Claim
91 words
An apparatus for evaluating foot borne motion in an individual comprising a support member, footwear mounting said support member thereon and adapted to attach said support member to a foot of said individual, means borne by the apparatus for detecting predetermined movement of the foot during said foot borne motion, and wherein said footwear has a mounting assembly on a lower portion thereof operable releasably to mount said support member on said lower portion of the footwear so as to permit support members of different operational capabilities to be mounted thereon.
Claim 5
Dependent Claim
17 words
The apparatus of claim 2 wherein said detecting means includes a sensor mounted on the support member.
Claim 6
Dependent Claim
50 words
The apparatus of claim 3 wherein said support member has a lower surface deployed for contact with a surface of support during said foot borne motion, said support member is oriented along a longitudinal axis and said sensor is operable to detect said predetermined movement relative to said longitudinal axis.
Claim 7
Dependent Claim
48 words
The apparatus of claim 4 wherein the support member has a forward portion and a rearward portion, two sensors are mounted in the forward portion on opposite sides of said longitudinal axis and two sensors are mounted in the rearward portion on opposite sides of said longitudinal axis.
Claim 8
Dependent Claim
26 words
The apparatus of claim 4 wherein said sensor is a mercury switch operable to close when said mercury switch is moved from a substantially horizontal attitude.
Claim 9
Dependent Claim
17 words
The apparatus of claim 4 wherein said support member has means for destabilizing said foot borne motion.
Claim 10
Dependent Claim
51 words
The apparatus of claim 7 wherein said destabilizing means includes a portion of said support member operable substantially to create a position about which said foot moves during said foot borne motion and a portion of the support member which flexes to accommodate the movement of the foot about said position.
Claim 11
Dependent Claim
91 words
The apparatus of claim 8 wherein said sensor is a normally open switch and the apparatus includes an electrical system having a source of electrical energy, a signalling mechanism and an electrical circuit operably interconnecting said switch, signalling mechanism and source of electrical energy and being operable during said foot borne motion to supply electrical energy from said source of electrical energy to the signalling mechanism upon closure of said normally open switch to activate the signalling mechanism to signal when said predetermined movement has occurred during said foot borne motion.
Claim 12
Dependent Claim
38 words
The apparatus of claim 9 wherein said switch is a mercury switch operable to remain open when disposed in a substantially horizontal attitude and to close upon reaching a second predetermined attitude deviated from said substantially horizontal attitude.
Claim 13
Dependent Claim
33 words
The apparatus of claim 9 wherein said signalling mechanism is a sound generating mechanism operable to indicate to said individual during said foot borne motion when said second predetermined attitude has been reached.
Claim 14
Independent Claim
165 words
An apparatus for evaluating foot borne motion in an individual comprising a support member having a lower surface deployed for contact with a surface of support during said foot borne motion, oriented along a longitudinal axis and having means for destabilizing said foot borne motion; footwear for attaching said support member to a foot of said individual and having a mounting assembly on a lower portion thereof operable releasably to mount said support member on said lower portion of the footwear so as to permit support members having different destabilizing means to be mounted thereon; and a sensor mounted on the support member operable to detect predetermined movement relative to said longitudinal axis during said foot borne motion and wherein said destabilizing means includes a portion of said support member operable substantially to create a position about which said foot moves during said foot borne motion and a portion of the support member which flexes to accommodate the movement of the foot about said position.
Claim 15
Independent Claim
165 words
An apparatus for evaluating foot borne motion in an individual comprising a support member having a lower surface deployed for contact with a surface of support during said foot borne motion, oriented along a longitudinal axis and having means for destabilizing said foot borne motion; footwear for attaching said support member to a foot of said individual and having a mounting assembly on a lower portion thereof operable releasably to mount said support member on said lower portion of the footwear so as to permit support members having different destabilizing means to be mounted thereon; and a sensor mounted on the support member operable to detect predetermined movement relative to said longitudinal axis during said foot borne motion and wherein said destabilizing means includes a portion of said support member operable substantially to create a position about which said foot moves during said foot borne motion and a portion of the support member which flexes to accommodate the movement of the foot about said position.
Claim 16
Independent Claim
96 words
A method for evaluating foot borne motion in an individual comprising: applying footwear to a foot of said individual having a support member extending downwardly therefrom for engagement with a surface of support during foot borne motion and extending substantially along a predetermined axis and at least one sensor mounted on the footwear in predetermined relation to said axis operable to detect predetermined movement of the foot during said foot borne motion; causing said individual to engage in said foot borne motion; and registering said predetermined movement detected by the sensor during said foot borne motion.
Claim 17
Independent Claim
96 words
A method for evaluating foot borne motion in an individual comprising: applying footwear to a foot of said individual having a support member extending downwardly therefrom for engagement with a surface of support during foot borne motion and extending substantially along a predetermined axis and at least one sensor mounted on the footwear in predetermined relation to said axis operable to detect predetermined movement of the foot during said foot borne motion; causing said individual to engage in said foot borne motion; and registering said predetermined movement detected by the sensor during said foot borne motion.
