Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
An automatic buckle release system comprising: buckle means including at least one buckle having interfitting male and female parts, latch means for releasably holding said parts together and shiftable to release said parts, lock means for releasably holding said latch means, actuator means for releasing said lock means to allow release of said latch means, said actuator means including electrically operated means, means for energizing said electrically operated means including a capacitor source of stored electrical energy, means for initially charging said capacitor source, and water activated normally open switch means electrically isolating said capacitor source from said electrically operated means and including a pair of electrodes for closing said switch means and connecting said source to said electrically operated means upon immersion of said electrodes in a body of water.
Claim 2
Dependent Claim
131 words
An automatic buckle release system comprising: buckle means including at least one buckle having interfitting male and female parts, latch means for releasably holding said parts together and shiftable to release said parts, lock means for releasably holding said latch means, actuator means for releasing said lock means to allow release of said latch means, said actuator means including electrically operated means, means for energizing said electrically operated means including a capacitor source of stored electrical energy, means for initially charging said capacitor source, and water activated normally open switch means electrically isolating said capacitor source from said electrically operated means and including a pair of electrodes for closing said switch means and connecting said source to said electrically operated means upon immersion of said electrodes in a body of water.
Claim 3
Dependent Claim
31 words
An automatic buckle release as defined in claim 1, including thermaL battery means connected to said capacitor source for initially charging said capacitor source upon activation of said thermal battery means.
Claim 4
Dependent Claim
36 words
An automatic buckle release system as defined in claim 1, wherein said buckle means includes a plurality of said buckles, and circuit means connecting said electrically operated means of each of said buckles to said source.
Claim 5
Dependent Claim
135 words
A canopy release system to automatically release an airman from a parachute comprising: harness means adapted to be worn by the airman and having a first pair of buckle parts carried thereby, a parachute pack including a harness having a second pair of buckle parts carried thereby and cooperable with said first pair of buckle parts to releasably connect the airman with the parachute, said buckles each having releasable latch means for holding the same connected, electrically operated means for releasing said latch means, means for energizing said electrically operable means including a capacitor source of stored electrical energy, normally open switch means interposed between said source and said electrically operable means and electrically isolating said capacitor source from said electrically operable means, and means for closing said switch means to release said latch means.
Claim 6
Dependent Claim
135 words
A canopy release system to automatically release an airman from a parachute comprising: harness means adapted to be worn by the airman and having a first pair of buckle parts carried thereby, a parachute pack including a harness having a second pair of buckle parts carried thereby and cooperable with said first pair of buckle parts to releasably connect the airman with the parachute, said buckles each having releasable latch means for holding the same connected, electrically operated means for releasing said latch means, means for energizing said electrically operable means including a capacitor source of stored electrical energy, normally open switch means interposed between said source and said electrically operable means and electrically isolating said capacitor source from said electrically operable means, and means for closing said switch means to release said latch means.
Claim 7
Dependent Claim
35 words
A canopy release system as defined in claim 4, wherein said means for closing said switch means includes a pair of electrodes, and switch closing means energized responsive to immersion of said electrodes in water.
Claim 8
Dependent Claim
55 words
A canopy release system as defined in claim 4, including means forming a seat for the airman and connected to said parachute pack, said means for closing said switch means including a pair of electrodes carried by said means forming a seat, and switch closing means energized responsive to immersion of said electrodes in water.
Claim 9
Dependent Claim
39 words
A canopy release system as defined in claim 4, including means forming a seat for the airman and connected to said parachute pack, said means for energizing said electrically operable means being carried by said means forming a seat.
Claim 10
Dependent Claim
71 words
A canopy release system as defined in claim 4, including means forming a seat for the airman and connected to said parachute pack, thermal battery means carried by said means forming a seat and connected to said capacitor source to charge the latter, said thermal battery means being normally inactive and being responsive to percussion to produce a charge of electricity, and including percussion producing means associated with said battery means.
Claim 11
Dependent Claim
34 words
A canopy release system as defined in claim 8, wherein said thermal battery means includes removable means for preventing operation of said percussion producing means, and including lanyard means for removing said removable means.
