Abstract: A system for controlling an emulsification process including the steps of acquiring images such as micrographs of an emulsification process at preset intervals between a start and an end of the emulsification process; detecting selected droplet characteristics such as size and count using image segmentation such as a histogram-based technique; analyzing the measured droplet characteristics; comparing the measured droplet characteristics with a desired droplet characteristic specification; and terminating the emulsification process when said desired droplet characteristic is achieved.

Abstract: A linear motor compressor within a cryogenic refrigerator wherein the compressor space, within which a gaseous fluid is alternately compressed and expanded, is formed by a stationary piston and a reciprocating armature that is concentric about the piston. The armature is supported along a clearance seal the stationary piston. An axial bore along the stationary piston conveys gaseous fluid from the compression space to a displacer within the cold finger of the cryogenic refrigerator. An isolator for reducing transimission into and out of the compressor comprising a dynamic absorber and flat springs mounted with a damping material between the compressor and a mounting frame. A sensor for detecting the position of the armature utilizes a target magnet whose magnetic flux lines are decoupled from the flux lines generated about the coil.
