Patent ID: 8316515

Claim:
An article of manufacture, comprising: a first interface body having a first major surface and a second major surface opposite the first major surface thereof, wherein a first side of a first layer of material of the first interface body defines the first major surface thereof, wherein interlock structures of a first configuration are only provided on at least a portion of the first major surface of the first interface body, wherein a first magnetic element is one of attached to the second major surface of the first interface body and embedded within the first interface body between said first and second major surfaces thereof, wherein the second major surface of the first interface body is devoid of interlock structures of a second configuration that interlock with the interlock structures of the first configuration, and wherein the first layer of material resides in-between said first configuration interlock structures of the first interface body and the first magnetic element; and a second interface body having a first major surface and a second major surface opposite the first major surface thereof, wherein a first side of a first layer of material of the second interface body defines the first major surface thereof, wherein interlock structures of the second configuration are only provided on at least a portion of the first major surface of the second interface body, wherein a second magnetic element is one of attached to the second major surface of the second interface body and embedded within the second interface body between said first and second major surfaces thereof, wherein the first layer of material resides in-between said second configuration interlock structures of the first interface body and the second magnetic element, wherein the second major surface of the second interface body is devoid of interlock structures of the first configuration, and wherein said second configuration interlock structures are mechanically engagable with and separable from said first configuration interlock structures.
