Abstract:
1. An assembly for releasably coupling a first element to a second element, comprising: A. a first element surface disposed on the first element, and B. a second element surface disposed on the second element, and C. a port, wherein the first element defines a cylindrical region disposed about a cylinder axis orthogonal to the first element surface and extending to a cylinder end surface transverse to the cylinder axis, and having a cylinder side surface disposed about the cylinder axis and extending from the cylinder end surface, wherein the second element includes a piston disposed about a piston axis orthogonal to the second element surface and extending to a piston end surface transverse to the piston axis, and having a piston side surface disposed about the piston axis and extending from the piston end surface, wherein at least one of (i) the first element surface is complementary to the second element surface, and (ii) the cylinder end surface is complementary to the piston end surface, and including a fluidic path extending from the port through one of the (a) piston to the piston end surface and (b) the cylindrical region to the cylinder end surface, and including a resilient seal extending from one of the piston side wall and the cylinder side wall, and wherein:
