Abstract: A digital fluid delivery and aspiration apparatus with a mechanical de-amplifier for the delivery or removal of discrete volumes of fluidic material from a surgical site. The apparatus has a syringe with a plunger designed to be powered by a pneumatic air supply system. A ratcheting mechanism attached to a pneumatic piston by a mechanical linkage causes the plunger of the syringe to inject discrete doses of the fluidic material into the surgical site or remove discrete amounts of fluidic material from the surgical site. The mechanical linkage increases the force provided to the plunger by the movement of the piston and also de-amplifies the movement of the piston into a lesser movement of the plunger.

Abstract: An electromagnetic interference filter for reducing conducted noise for alternating current power lines, wherein a compact component geometry integrates matched material characteristics to create a coaxial inductor and square axisymmetric capacitor configuration capable of providing reduced size, increased frequency performance and improved voltage isolation over traditional magnet wire construction methods.
