Abstract
Abstract A monitoring device in the form of a ribbon or tape switch used to detect the distance an object is hit out in a field or open area. The switch consists of two conductor contacts mounted continuously on an insulated synthetic material to provide electrical continuity when an object touches it or rolls across it. The switch is sensitive enough to close from the weight of one ounce avoirdupois. The switch is constructed with a low profile angular shape so an object can roll over it without impeding its destination. The switch is made of simple enough construction to allow economic large scale manufacturing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
90 words
A tape switch comprising: an elongated narrow low profile angular shaped resilient insulated ribbon material; an electrical conductor secured on the base of the interior of said ribbon material; and a second electrical conductor secured on opposite interior surface of said ribbon material, opposite and parallel to said first electrical conductors; said conductors being spaced from each other an amount such that no electrical interconnection is provided therebetween so that deflection imparted to said ribbon switch by an object will cause a portion of said conductors to contact each other.
Claim 2
Dependent Claim
90 words
A tape switch comprising: an elongated narrow low profile angular shaped resilient insulated ribbon material; an electrical conductor secured on the base of the interior of said ribbon material; and a second electrical conductor secured on opposite interior surface of said ribbon material, opposite and parallel to said first electrical conductors; said conductors being spaced from each other an amount such that no electrical interconnection is provided therebetween so that deflection imparted to said ribbon switch by an object will cause a portion of said conductors to contact each other.
Claim 3
Dependent Claim
28 words
The combination as claimed in claim 1 wherein said angular shaped resilient insulated material is bent upon itself to form the necessary spring action required for proper switching.
Claim 4
Dependent Claim
34 words
The combination as claimed in claim 1 wherein said angular shaped resilient insulated material geometrical shape provides the necessary mechanical advantage and sensitivity to close said electrical conductors from weight of one ounce avoirdupois.
Claim 5
Dependent Claim
22 words
The combination as claimed in claim 1 wherein said angular material low profile prevents a rolling object from deviating from its path.
Claim 6
Dependent Claim
58 words
The combination as claimed in claim 1 wherein said electrical conductors are circular and are secured to said insulation material by slots, said slots are circular in shape to accomodate said conductors, said slot opening is slightly less than the diameter of said conductor to provide necessary gripping action, but large enough to provide switch contact surface area.
Claim 7
Dependent Claim
25 words
The combination as claimed in claim 1 wherein said electrical conductors are metallic foil, said metallic foil is held to insulated surface with an adhesive.
Claim 8
Dependent Claim
23 words
The combination as claimed in claim 1 wherein said electrical conductors is in the form of metallic paint applied to said insulated material.
Claim 9
Independent Claim
63 words
A method of forming a long narrow continuous ribbon of synthetic insulation material into a tape switch, said method comprising the steps of: inserting a pair of conductors, a predetermined depth and equally spaced from center-line of said insulation material with conductor inserting probes; forming said insulation material into an angular shape using two side support guides, a form and center-line guide rod.
Claim 10
Independent Claim
63 words
A method of forming a long narrow continuous ribbon of synthetic insulation material into a tape switch, said method comprising the steps of: inserting a pair of conductors, a predetermined depth and equally spaced from center-line of said insulation material with conductor inserting probes; forming said insulation material into an angular shape using two side support guides, a form and center-line guide rod.
Claim 11
Dependent Claim
31 words
A method as defined in claim 8 in which said conductors inserting probes apply a predetermined amount of heat and pressure to set conductors at proper position into said insulation material.
Claim 12
Dependent Claim
30 words
A method as defined in claim 8 which further includes heating said form and said center-line guide rod to shape and set said insulation material into a predetermined angular shape.
Claim 13
Dependent Claim
42 words
A method as defined in claim 8 in which cutting tools are used in lieu of said heated inserting probes, said cutting tools providing grooves of the proper size and shape to accept said conductors at proper position on said insulation material.
