Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
Apparatus of the class described comprising, in combination: a housing having a substantially cylindrical interior wall, and a conductive top and bottom; a plurality of conductors enclosed by said housing and electrically insulated from the conductive top and bottom of said housing; and a conductive sphere enclosed within said housing and forming a conductive path between the conductive top or bottom of said housing and at least one of said plurality of conductors when said conduCtive sphere is at rest with respect to said conductive housing.
Claim 2
Dependent Claim
86 words
Apparatus of the class described comprising, in combination: a housing having a substantially cylindrical interior wall, and a conductive top and bottom; a plurality of conductors enclosed by said housing and electrically insulated from the conductive top and bottom of said housing; and a conductive sphere enclosed within said housing and forming a conductive path between the conductive top or bottom of said housing and at least one of said plurality of conductors when said conduCtive sphere is at rest with respect to said conductive housing.
Claim 3
Dependent Claim
130 words
An antidisturbance switch comprising, in combination: a cylindrical housing having conductive end portions; a flexible printed circuit grid attached to the inner walls of said cylindrical housing, said flexible printed circuits grid having a plurality of equally spaced parallel conductive strips attached thereto; conductive means insulated from said cylindrical housing connected to at least some of the conductive strips of said flexible printed circuit grid; and a conductive sphere enclosed within said cylindrical housing, said conductive sphere forming a normally conductive path between a conductive end portion of said cylindrical housing and said conductive means when said conductive sphere is at rest relative to said cylindrical housing and momentarily opening said conductive path when a disturbance of the switch causes said conductive sphere to move relative to said cylindrical housing.
Claim 4
Dependent Claim
130 words
An antidisturbance switch comprising, in combination: a cylindrical housing having conductive end portions; a flexible printed circuit grid attached to the inner walls of said cylindrical housing, said flexible printed circuits grid having a plurality of equally spaced parallel conductive strips attached thereto; conductive means insulated from said cylindrical housing connected to at least some of the conductive strips of said flexible printed circuit grid; and a conductive sphere enclosed within said cylindrical housing, said conductive sphere forming a normally conductive path between a conductive end portion of said cylindrical housing and said conductive means when said conductive sphere is at rest relative to said cylindrical housing and momentarily opening said conductive path when a disturbance of the switch causes said conductive sphere to move relative to said cylindrical housing.
Claim 5
Dependent Claim
16 words
Apparatus of the class described in claim 2, wherein said conductive means is an insulated wire.
Claim 6
Dependent Claim
70 words
Apparatus of the class described in claim 2, wherein said conductive means is connected to alternate conductive strips of said flexible printed circuit grid and wherein the spacing of the equally spaced parallel conductive strips of said flexible printed circuit grid is related to the radii of said conductive sphere and said cylindrical housing such that said conductive sphere when at rest is in contact with two adjacent conductive strips.
Claim 7
Dependent Claim
70 words
Apparatus of the class described in claim 2, wherein said conductive means is connected to all of the conductive strips of said flexible printed circuit grid and the spacing of the conductive strips of said flexible printed circuit grid is related to the radii of said conductive sphere and said cylindrical housing, such that the conductive sphere when at rest is in contact with only one of the conductive strips.
Claim 8
Dependent Claim
21 words
Apparatus as recited in claim 1 wherein the conducting top and conductive bottom of said housing have substantially planar interior surfaces.
