Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
Footwear comprising: at least one light source, located on said footwear to be visible exteriorly thereof, a power source for energizing said light source, a circuit for selectively electrically connecting said power source with said at least one light source to illuminate said source, a switch, which alternates between "off" and "on" states responsive to motion of said footwear, said circuit being adapted to so connect said power source to said light source responsive to the transition of said switch to "off" to "on" state, and a timing circuit being adapted to disconnect said power source from said light source a predetermined time after said transition.
Claim 2
Dependent Claim
106 words
Footwear comprising: at least one light source, located on said footwear to be visible exteriorly thereof, a power source for energizing said light source, a circuit for selectively electrically connecting said power source with said at least one light source to illuminate said source, a switch, which alternates between "off" and "on" states responsive to motion of said footwear, said circuit being adapted to so connect said power source to said light source responsive to the transition of said switch to "off" to "on" state, and a timing circuit being adapted to disconnect said power source from said light source a predetermined time after said transition.
Claim 3
Dependent Claim
13 words
Footwear as claimed in claim 1 wherein said light source is an LED.
Claim 4
Dependent Claim
15 words
Footwear as claimed in claim 1 wherein said motion responsive means is a mercury switch.
Claim 5
Dependent Claim
15 words
Footwear as claimed in claim 2 wherein said motion responsive means is a mercury switch.
Claim 6
Dependent Claim
100 words
Footwear comprising: at least one light source located on said footwear to be visible exteriorly thereof, a power source for energizing said light source, means responsive to motion of said footwear to cause illumination of said light source by said power source, including a switch which alternates between "off" and "on" states responsive to motion of said footwear, and circuit means adapted to cause illumination of said light source by said power source responsive to the transition of said switch from "off" to "on" state and a timing circuit adapted to terminate said illumination a predetermined period after said transition.
Claim 7
Dependent Claim
100 words
Footwear comprising: at least one light source located on said footwear to be visible exteriorly thereof, a power source for energizing said light source, means responsive to motion of said footwear to cause illumination of said light source by said power source, including a switch which alternates between "off" and "on" states responsive to motion of said footwear, and circuit means adapted to cause illumination of said light source by said power source responsive to the transition of said switch from "off" to "on" state and a timing circuit adapted to terminate said illumination a predetermined period after said transition.
