Abstract: An exemplary system includes a power distribution block and a set of connectors that are configured to be removably coupled to the power distribution block. The exemplary system is useful for distributing power (pneumatic, hydraulic, electrical, etc.). The set of connectors includes connectors of at least two types. The block includes two or more conduction paths that each have two opposite ends. The block and connectors are configured such that one or more connectors of any type in the set can be removably coupled to at least one of the conduction paths, at either end of the paths. Each end of each conduction path connects (both electrically and mechanically) to no more than one connector. Methods and other systems with different advantageous configurations are also described.

Abstract: An electrical cable includes a second strand, and a third strand braided together. The first and second strands are electrically conductive and electrically insulated from each other, and the third strand is electrically non-conductive. The geometry imparted to the conductive strands by the braided configuration results in the cable exhibiting improved noise rejection, lower inductance per unit length, reduced signal attenuation and reduced resistance compared with cables having twisted or parallel pairs of conductive strands. The cable is particularly suited to audio, video and computer applications. Cables that have larger numbers of strands braided together, and multilayer cables are also described.
