Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A head gear apparatus comprising a transparent pliable bag means containing a transparent fluid, a valve means within said bag means, said valve means capable of allowing said fluid to pass through a pressure sensitive transducer within said bag means to register pressure induced on said containerized fluid by an external blow on said bag means, a power source means connected to said transducer, a microprocessor means, a transmitter means, two or more separate compartments in said bag means that are contiguous through said valve means, and a fluid dye means within an isthmus holding the valve means.
Claim 2
Dependent Claim
98 words
A head gear apparatus comprising a transparent pliable bag means containing a transparent fluid, a valve means within said bag means, said valve means capable of allowing said fluid to pass through a pressure sensitive transducer within said bag means to register pressure induced on said containerized fluid by an external blow on said bag means, a power source means connected to said transducer, a microprocessor means, a transmitter means, two or more separate compartments in said bag means that are contiguous through said valve means, and a fluid dye means within an isthmus holding the valve means.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1, that has a dye incorporated into material of which said isthmus is made.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1, that has valves that admit fluid in only one direction.
Claim 5
Dependent Claim
14 words
The apparatus of claim 1, that has valves that admit fluid in both directions.
Claim 6
Dependent Claim
12 words
The apparatus of claim 1, that has valves that respond to demand.
Claim 7
Dependent Claim
19 words
The apparatus of claim 1, that further comprises a light means electronically connected to the transducer and power source.
Claim 8
Dependent Claim
19 words
The apparatus of claim 1, that further comprises an buzzer means electronically connected to the transducer and power source.
Claim 9
Dependent Claim
18 words
The apparatus of claim 1, that has a receiver means that registers the transmission sent by said apparatus.
Claim 10
Dependent Claim
9 words
The apparatus of claim 1 that contains a gel.
Claim 11
Dependent Claim
17 words
The apparatus of claim 1 that further comprises an inner most layer that contains a thixotropic material.
Claim 12
Dependent Claim
71 words
A process wherein the force of a blow is dissipated through a fluid or gel contained within a transparent pliable bag means, wherein pressure on said fluid or gel activates a valve means, said valve means affixed at a specific threshold pressure, and wherein a pressure sensitive transducer means send impulses to a microcomputer that digitizes the pressure impulse, wherein the digitized recording is transmitted to a receiver monitored by officials.
Claim 13
Dependent Claim
71 words
A process wherein the force of a blow is dissipated through a fluid or gel contained within a transparent pliable bag means, wherein pressure on said fluid or gel activates a valve means, said valve means affixed at a specific threshold pressure, and wherein a pressure sensitive transducer means send impulses to a microcomputer that digitizes the pressure impulse, wherein the digitized recording is transmitted to a receiver monitored by officials.
Claim 14
Dependent Claim
31 words
The process of claim 11, wherein a dye is released into the transparent pliable bag means by the flow of fluid or gel in response to the force of a blow.
