Abstract

An apparatus with (a) a conformable contact member with a base and a contact layer; and (b) a magnet integral with or attached to the base, wherein, when the apparatus is placed on a target surface, the magnet and the target surface attract each other such that the contact layer is secured against the target surface.

First claim

What is claimed is:

1. An apparatus, comprising:
a conformable contact member comprising a base and a conformable contact layer, the conformable contact layer including a plurality of electrically conductive and flexible bristles
positioned within a periphery of the base; and
a magnet integral with or attached to the base, wherein,
when the apparatus is placed on a target surface, the magnet and the target surface attract each other such that the bristles are in contact with the target surface.

2. The apparatus of claim 1 , wherein the base is a conformable base.

3. The apparatus of claim 1 , wherein the base has a circular periphery.

4. The apparatus of claim 1 , wherein the apparatus has a terminal for electrical connections thereto.

5. An apparatus, comprising:
at least one conformable contact member comprised of a base and a contact layer;
at least one magnet; and
a moveable housing comprising a plurality of wheels and configured to hold the at least one contact member and the at least one magnet, wherein:
the housing has at least a first side, a second side, and a top,
the plurality of wheels include a first plurality of wheels attached to the first side and a second plurality of wheels attached to the second side,
the at least one conformable contact member is mounted to the housing,
the at least one magnet is attached to at least one of a surface of the first side or a surface of the second side, and
when the apparatus is placed on a target surface, the at least one magnet and target surface attract each other such that the contact layer is secured against the target surface.

6. The apparatus of claim 5 , wherein the at least one magnet is positioned such that a predetermined gap exists between the target surface and a bottom surface of the at least one magnet.

7. The apparatus of claim 5 , wherein the at least one magnet comprises a first magnet attached to the surface of the first side and a second magnet attached to the surface of the second side.

8. The apparatus of claim 5 , wherein the surface of the first side is an inside surface of the first side or an outside surface of the first side.

9. An apparatus, comprising:
at least one conformable contact member comprised of a base and a contact layer;
at least one magnet;
a moveable housing that holds the at least one contact member and the at least one magnet; and
an adjustable member coupled to the base, the adjustable member allowing for a position of the base to be adjusted with respect to a target surface wherein,
when the apparatus is placed on the target surface, the at least one magnet and the target surface attract each other such that the each contact layer is secured against the target surface.

10. The apparatus of claim 9 , wherein the conformable contact member comprises bristles that are flexible so that when the target surface is curved the bristles are electrically conductive with the target surface.

11. The apparatus of claim 10 , wherein the bristles are flexible so that when the target surface is concave the bristles are electrically conductive with the target surface.

12. The apparatus of claim 10 , wherein the bristles are flexible so that when the target surface is concave, at least half of the bristles contact the target surface.

13. The apparatus of claim 9 , wherein the base has an aperture and
a stem protrudes through the aperture in the base.

14. The apparatus of claim 13 , wherein the stem is attached to or integrated with the magnet.
