The present invention relates to an electrolyte for the electrochemical deposition of palladium or palladium alloys on metallic or conductive substrates. The plate is configured to transmit movement of the post to the membrane in a rigid, or substantially rigid, piston-like manner. The net tracing algorithm involves determining for each of the meshes a net of paths having a connectivity substantially the same as that of the base domain. The image sensor receives the first portion of light and produces a detection signal. An adjustable dorsal strap is configured to wrap over the first and second permanent magnets as well as the bladder thereby providing a compressive force.
