Abstract
Abstract A scoring apparatus includes a pad upon which a parachutist impacts, containing normally separated and electrically insulated conductive sheets. A fish net type of insulator disposed between the sheets permits contact therebetween upon impact by a jumper. A voltage representative of the point of contact of the jumper upon the pad is thereby generated and supplied to a display device which displays the accuracy of the landing upon the pad.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
321 words
A scoring apparatus comprising: an elastically deformable target structure upon which an object is to impact, said target structure containing first and second spaced-apart members, each of which is made of pliable material, normally physically separated from one another in the absence of the impact of an object by a net-like sheet of pliable insulator material, capable of supporting said spaced-apart members relative to each other in the absence of the impact of an object while permitting said spaced-apart members to elastically deform and come into physical and electrical contact with one another upon impact by an object on either of said members of pliable material; and means, connected to said spaced-apart members, for generating an electrical signal representative of the position on said target structure upon which an object impacts and thereby causes physical and electrical contact between said spaced-apart members; and wherein said first member is a sheet of pliable material which is at least partially conductive, said second member is a pliable sheet of partially conductive material, and said means comprises a first source of reference potential connected to a first selected location on said pliable sheet of partially conductive material, a second source of reference potential connected to a second selected location spaced-apart from said first selected location on said pliable sheet of partially conductive material, thereby establishing a voltage gradient across said second member between said first and second spaced-apart locations, a conductor connected to said pliable sheet of at least partially conductive material, and voltage conversion circuit means, connected to said conductor, for storing a voltage lying within said gradient supplied to said conductor in response to the impact of an object on said target structure and for converting said stored voltage to an electrical output representative of the distance between the position of impact of said object and one of said first and second selected locations on said pliable sheet of partially conductive material.
Claim 2
Dependent Claim
321 words
A scoring apparatus comprising: an elastically deformable target structure upon which an object is to impact, said target structure containing first and second spaced-apart members, each of which is made of pliable material, normally physically separated from one another in the absence of the impact of an object by a net-like sheet of pliable insulator material, capable of supporting said spaced-apart members relative to each other in the absence of the impact of an object while permitting said spaced-apart members to elastically deform and come into physical and electrical contact with one another upon impact by an object on either of said members of pliable material; and means, connected to said spaced-apart members, for generating an electrical signal representative of the position on said target structure upon which an object impacts and thereby causes physical and electrical contact between said spaced-apart members; and wherein said first member is a sheet of pliable material which is at least partially conductive, said second member is a pliable sheet of partially conductive material, and said means comprises a first source of reference potential connected to a first selected location on said pliable sheet of partially conductive material, a second source of reference potential connected to a second selected location spaced-apart from said first selected location on said pliable sheet of partially conductive material, thereby establishing a voltage gradient across said second member between said first and second spaced-apart locations, a conductor connected to said pliable sheet of at least partially conductive material, and voltage conversion circuit means, connected to said conductor, for storing a voltage lying within said gradient supplied to said conductor in response to the impact of an object on said target structure and for converting said stored voltage to an electrical output representative of the distance between the position of impact of said object and one of said first and second selected locations on said pliable sheet of partially conductive material.
Claim 3
Dependent Claim
22 words
A scoring apparatus according to claim 1, wherein said sheet of at least partially conductive material is a sheet of conductive material.
Claim 4
Dependent Claim
15 words
A scoring apparatus according to claim 1, wherein said first member is only partially conductive.
Claim 5
Dependent Claim
49 words
A scoring apparatus according to claim 1, wherein said pliable sheet of partially conductive material includes a strip of conductive film passing through one of said first and second selected locations, one of said first and second sources of reference potential being connected to said strip of conductive film.
Claim 6
Dependent Claim
48 words
A scoring apparatus according to claim 1, further including means, coupled to said electrical signal generating means, for controllably providing an indication only of the position on said target structure upon which an object initially impacts, irrespective of any subsequent impact on said target structure by an object.
