Abstract: A level sensor assembly (552) for estimating a level of a dielectric powder (412) in a container assembly (544) includes a first electrode member (554) that is coupled to the container assembly (544); a second electrode member (556) that is coupled to the container assembly (544): and a control system (424). The second electrode member (556) is spaced apart from the first electrode member (554) and configured so that powder (512) in the container assembly (544) is positioned at least partly between the electrode members (554) (556). The control system (424) utilizes a capacitance between the electrode members (554) (556) to estimate the level of the powder (512) in the container assembly (544).

Abstract: A stage assembly (10) includes a stage (14), and a fluid actuator assembly (24) that moves the stage (14). The fluid actuator assembly (24) includes a piston housing (32) that defines a piston chamber (34); (ii) a piston (36) that separates the piston chamber (34) into a first chamber (34A) and a second chamber (34B); (iii) a supply valve (38C) that controls the flow of the working fluid (40) into the first chamber (34A); and (iv) an exhaust valve (38D) that controls the flow of the working fluid (40) out of the first chamber (34A). The supply valve (38C) has a supply orifice (250G) having a supply orifice area, and the exhaust valve (38D) has an exhaust orifice (352G) having an exhaust orifice area. Moreover, the supply orifice area is different from the exhaust orifice area. Further multiple valves of different sizes can be used in combination for the supply and exhaust for each chamber (34A), (34B).
