Cards and assemblies with user interfaces

Abstract

Laminated cards with user interfaces are provided. The user interfaces can have enhanced tactile feel. In one embodiment, a card may be constructed to have a dual-layer user interface. In another embodiment, a card may be constructed to include a support structure. In yet another embodiment, a card may include a relatively soft material that covers at least a portion of the user interface. In yet another embodiment, a card may include a user interface that is fluidically coupled to a bladder. In a further embodiment, a card can include any combination of a user interface, which may be a dual-layer user interface, a support structure, a soft material that at least partially covers a user interface, and a bladder.

         18 . A device comprising:
 a flexible printed circuit board having a plurality of electrical contacts; and   a dual-layer user interface mounted to the flexible printed circuit board, the dual-layer user interface having a portion operative to form an electrical connection with one of the electrical contacts during an input event.   
     
     
         19 . The device of  claim 18 , further comprising an adhesive layer that adheres to a top surface of the flexible printed circuit board and a top surface of the dual-layer user interface. 
     
     
         20 . The device of  claim 18 , wherein the dual-layer user interface comprises a force concentration structure. 
     
     
         21 . The device of  claim 18 , wherein the dual-layer user interface is an integrated component. 
     
     
         22 . The device of  claim 18 , wherein the dual-layer user interface comprises:
 a first user interface element mounted to the flexible printed circuit board; and   a second user interface element mounted above the first user interface element such that a gap of a predetermined distance exists between the first and second user interface elements during times other than during the input event.   
     
     
         23 . The device of  claim 18 , wherein the dual-layer user interface is a first dual-layer interface, the device further comprising a second dual-layer user interface. 
     
     
         24 . A method comprising:
 providing a flexible printed circuit board having a plurality of electrical contacts; and   mounting a dual-layer user interface on the flexible printed circuit board, the dual-layer user interface having an inner layer operative to engage one of the electrical contacts during an input event.   
     
     
         25 . The method of  claim 24 , further comprising:
 applying an adhesive to the flexible printed circuit board and the dual-layer user interface.
