Abstract: A prosthesis assembly for use with a scapula is disclosed. The prosthesis assembly includes a glenoid bearing support and a bearing. The glenoid bearing support includes a glenoid vault-occupying portion configured to occupy at least a portion of a glenoid vault of the scapula, the glenoid-vault occupying portion having a first coupling component. The glenoid bearing support further includes a glenoid rim replacement portion attached to the glenoid vault-occupying portion. The bearing defines a bearing surface and has a second coupling component configured to cooperate with the first coupling component to couple the bearing to the glenoid vault-occupying portion. The glenoid vault-occupying portion defines a bearing-side end portion and an opposite-side end portion. The glenoid rim replacement portion projects outwardly from the bearing-side end portion of the glenoid vault-occupying portion. The glenoid bearing support defines a bone graft receptacle.

Abstract: In one embodiment, an electrochemical cell comprises: a first electrode and a second electrode with a membrane disposed therebetween to form a membrane electrode assembly, a bipolar plate disposed on a side of the membrane electrode assembly, and a thermistor element disposed proximate an edge of the bipolar plate. In one embodiment, a method of cooling an electrochemical cell comprises: radiating heat from a fin extending from an edge of a flow field support member of the electrochemical cell and flowing air along the fin to convectively remove heat from the flow field support member.

Abstract: In one embodiment a compression device comprises: a base plate having a surface, a spring support plate, a resilient member, a manifold, and a side plate. The resilient member is disposed between the spring support plate and the base plate in compressible mechanical communication with the base plate to enable a force to be imparted to the base plate in a direction normal to the surface. The side plate is disposed from the spring support plate to the manifold, wherein the side plate physically engages a periphery of the manifold and a periphery of the spring support plate.

Abstract: In one embodiment, an electrochemical cell comprises: a membrane electrode assembly comprising a first active area and an opposingly positioned second active area, and a flow field support member disposed adjacent to said membrane electrode assembly. Each of the active areas comprises an electrode, and has a length to width ratio configured such that, during use of the electrochemical cell, a temperature differential measured across the shortest distance from a center of the active areas to an edge of the active areas is less than about 15° C. The flow field support member has a flow region that aligns with either the first active area or the second active area.
