Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
138 words
In an anti-bed-wetting device consisting of an electrical sounder adapted to be triggered by the closing of a pair of contacts, a sensor, and an electrically conducting means between said sounder and said sensor, the improvement comprising a sensor comprising two relatively long, narrow strips of a conductive fabric wherein said fabric has a conductive side and a nonconductive side, said strips being of substantially the same size and configuration and being placed in back-to-back relationship with the nonconductive sides of each sheet in contact with the other and a sheet of fabric or cloth enclosing said strips and at one end of said sensor two small patches of electrically conductive Velcro® in back-to-back relationship, with the attaching sides of the Velcro® facing outwardly, one of said Velcro® patches being in electrical contact with each of said strips.
Claim 2
Dependent Claim
138 words
In an anti-bed-wetting device consisting of an electrical sounder adapted to be triggered by the closing of a pair of contacts, a sensor, and an electrically conducting means between said sounder and said sensor, the improvement comprising a sensor comprising two relatively long, narrow strips of a conductive fabric wherein said fabric has a conductive side and a nonconductive side, said strips being of substantially the same size and configuration and being placed in back-to-back relationship with the nonconductive sides of each sheet in contact with the other and a sheet of fabric or cloth enclosing said strips and at one end of said sensor two small patches of electrically conductive Velcro® in back-to-back relationship, with the attaching sides of the Velcro® facing outwardly, one of said Velcro® patches being in electrical contact with each of said strips.
Claim 3
Dependent Claim
56 words
The device of claim 1 wherein said electrically conductive means comprises a pair of face-to-face conductive fabric strips each of which has a patch of inwardly facing conductive Velcro® at the terminal ends thereof, said strips being enclosed in a fabric sheath and said Velcro® strips adapted to mate with said corresponding patches on said sensor.
