Abstract
Abstract A self-defense apparatus includes a battery-powered source of high voltage arranged in an insulated housing and a finger probe device which is strapped to one finger of one hand of the user and is electrically connected to the source of high voltage. The finger probe device includes a layer of electrical insulation disposed between the finger and two metal prongs which protrude outwardly adjacent the distal end of the finger. One prong couples to the hot side of the source of high voltage and the other prong couples to the ground side of the source of high voltage. A two-conductor cable connects the two prongs to the source of high voltage and when both prongs are placed in contact with an electrically conductive surface, they deliver in excess of 1,200 volts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A self-defense apparatus to be worn by the user which comprises: a glove member including a wrist strap for securement about the wrist of the user and a pouch; a source of high voltage housed in a portable module and suitably adapted to be retained in said pouch; and a finger probe sleeve comprising a portion of said glove member and being electrically coupled to said source of high voltage and suitably arranged to slide over and be worn on a finger of the hand wearing said glove member, said finger probe sleeve including two electrically conductive, outwardly protruding, pointed prongs and a layer of electrical insulating material disposed between said finger and said two prongs.
Claim 2
Dependent Claim
116 words
A self-defense apparatus to be worn by the user which comprises: a glove member including a wrist strap for securement about the wrist of the user and a pouch; a source of high voltage housed in a portable module and suitably adapted to be retained in said pouch; and a finger probe sleeve comprising a portion of said glove member and being electrically coupled to said source of high voltage and suitably arranged to slide over and be worn on a finger of the hand wearing said glove member, said finger probe sleeve including two electrically conductive, outwardly protruding, pointed prongs and a layer of electrical insulating material disposed between said finger and said two prongs.
Claim 3
Dependent Claim
30 words
The apparatus of claim 1 wherein said finger probe sleeve and said wrist strap are connected together as part of the same single glove member by an intermediate glove section.
Claim 4
Dependent Claim
17 words
The apparatus of claim 2 which further includes a canister holder joined to said intermediate glove section.
Claim 5
Dependent Claim
38 words

Claim 6
Dependent Claim
87 words
A glove-like assembly designed to be worn on a hand and configured for carrying and storage of various components and subassemblies associated with the delivery of a high-voltage potential from a finger location, said glove-like assembly comprising: a glove member including a finger sleeve, a wrist strap and an intermediate section connecting together said finger sleeve and said wrist strap; a high-voltage-producing module carried by said wrist strap; and two outwardly protruding, electrically conductive prongs, carried by said finger sleeve and electrically connected to said high-voltage-producing module.
Claim 7
Dependent Claim
87 words
A glove-like assembly designed to be worn on a hand and configured for carrying and storage of various components and subassemblies associated with the delivery of a high-voltage potential from a finger location, said glove-like assembly comprising: a glove member including a finger sleeve, a wrist strap and an intermediate section connecting together said finger sleeve and said wrist strap; a high-voltage-producing module carried by said wrist strap; and two outwardly protruding, electrically conductive prongs, carried by said finger sleeve and electrically connected to said high-voltage-producing module.
Claim 8
Dependent Claim
42 words
The glove-like assembly of claim 5 wherein said finger sleeve includes an inner electrical insulating layer and an exterior covering, said two prongs being located between said inner electrical insulating layer and said exterior covering and protruding outwardly through said exterior covering.
Claim 9
Dependent Claim
22 words
The glove-like assembly of claim 5 wherein said wrist strap includes a pouch, and said high-voltage-producing module is disposed within said pouch.
