Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
Headwear comprising a covering for at least a portion of the head of a user, said covering including sensing means for detecting selected motion of the head of a user wearing said headwear, said sensing means including at least one signal generating member and an actuation member for actuating said signal generating member in response to acceleration of said actuating member above a selected magnitude of acceleration, said actuating member including a first directional and a second directional switch with said first and second directional switches being disposed each extending along a separate axis and with said axes extending at a selected angle to one another.
Claim 2
Dependent Claim
106 words
Headwear comprising a covering for at least a portion of the head of a user, said covering including sensing means for detecting selected motion of the head of a user wearing said headwear, said sensing means including at least one signal generating member and an actuation member for actuating said signal generating member in response to acceleration of said actuating member above a selected magnitude of acceleration, said actuating member including a first directional and a second directional switch with said first and second directional switches being disposed each extending along a separate axis and with said axes extending at a selected angle to one another.
Claim 3
Dependent Claim
22 words
The invention as claimed in claim 1 wherein said headwear includes a transmitter for transmitting a said signal to a remote receiver.
Claim 4
Dependent Claim
14 words
The invention as claimed in claim 1 wherein said selected angle is approximately 90°.
Claim 5
Dependent Claim
27 words
The invention as claimed in claim 1 wherein said actuating member includes a third directional switch disposed along an axis that extends perpendicular to said separate axes.
Claim 6
Dependent Claim
22 words
The invention as claimed in claim 4 wherein said headwear includes a transmitter for transmitting a said signal to a remote receiver.
Claim 7
Dependent Claim
17 words
The invention as claimed in claims 1, 2, or 3 wherein said headwear is an athletic helmet.
Claim 8
Dependent Claim
27 words
The invention as claimed in claim 6 wherein said helmet has a storage portion provided with a chamber and said sensing member is enclosed in said chamber.
Claim 9
Dependent Claim
102 words
The invention as claimed in claim 1 wherein said directional switches are each provided with a housing having an electrical contact at one end thereof and a conductive member movably carried in said housing, said housing including a restraining device acting on said conductive member to restrain movement of said conductive member along the associated directional axis until the acceleration of a selected magnitude acts on said conductive member to overcome the force of said restraining device whereupon said conductive member will move to engage said electrical contact and close a circuit of said sensing means to actuate said signal generating member.
Claim 10
Dependent Claim
34 words
The invention as claimed in claim 8 wherein each said housing has an electrical contact at an end opposite said one end so that each said sensor will respond to acceleration in opposite directions.
Claim 11
Dependent Claim
31 words
The invention as claimed in claim 8 wherein each said housing includes resilient member to return said respective conductive member to a neutral position after sensing acceleration above a selected magnitude.
