Abstract: A biometric sensor array system may include a skin contact layer, a flexible printed circuit board (“PCB”), and a plurality of force sensing resistors (“FSRs”). The flexible PCB may be positioned adjacent the skin contact layer and may have a connector tail. Each FSR may be positioned on the flexible PCB. The connector tail may be adapted to electrically connect the plurality of FSRs to a signal receiving component. The flexible PCB may be configured so that one or more of the plurality of FSRs may be trimmed away from the flexible PCB so that the connector tail is still adapted to electrically connect a remaining one or more of the plurality of FSRs to the signal receiving component.

Abstract: A socket may be for coupling a prosthetic upper extremity to a residual limb of a user. The socket may include a proximal socket portion and a distal socket portion coupled to the proximal socket portion by a polycentric joint. The polycentric joint may include a plate having a first end coupled to the proximal socket portion via a first fastener, and a second end coupled to the distal socket portion via a second fastener. The proximal socket portion may be rotatable relative to the distal socket portion about a first axis passing through the first fastener and about a second axis passing through the second fastener.
