Abstract: An apparatus includes a primary device, a secondary device, and an umbilical system. The umbilical system comprises an umbilical linking the primary device and the secondary device, and a control system configured alter a directionality of the umbilical during deployment of the secondary device away from the primary device by at least controlling a configuration of a shape memory material comprising the umbilical.

Abstract: An electrospray device includes an electrospray emitter adapted to receive electrospray fluid; an extractor plate spaced from the electrospray emitter and having at least one aperature; and a power supply for applying a first voltage between the extractor plate and emitter for generating at least one Taylor cone emission through the aperature to create an electrospray plume from the electrospray fluid, the extractor plate as well as accelerator and shaping plates may include a porous, conductive medium for transporting and storing excess, accumulated electrospray fluid away from the aperature.
