Abstract

A fluid mover includes a first dynamic armature attached to a flexible member and a second dynamic armature attached to a second flexible member. The fluid mover also includes a housing and first and second flexible members being attached to the housing so as to form a fluid chamber volume bounded by the housing and first and second flexible members. A stationary current carrying coil positioned between first and second armatures. The current carried by the coil generates a magnetic force acting on the armatures and wherein coil and armatures are positioned and configured so as to ensure that the instantaneous magnetic force experienced by the two armatures will always be identical regardless of the relative positions of the armatures and regardless of the time varying properties of the current.

Abstract

A cantilever fan including a cantilever blade that is clamped at one end. The fan includes an actuator that applies a periodic force to the blade resulting in periodic deflections of the blade.

• F04D 33/00 - Non-positive-displacement pumps with other than pure rotation, e.g. of oscillating type
• F04D 29/00 - Details, component parts, or accessories
• F04D 35/00 - Pumps producing waves in liquids, i.e. wave-producers

Abstract

An energy transfer fluid diaphragm including a diaphragm substrate including cutouts. The cutouts are covered with a sealing layer bonded to the diaphragm substrate. The cutouts are configured to bend thereby allowing displacement of a center portion of the diaphragm. The displacement of the center portion transfers energy to a fluid located adjacent to the diaphragm.

IPC Classes  ?

• F03G 7/00 - Mechanical-power-producing mechanisms, not otherwise provided for or using energy sources not otherwise provided for
• F16K 7/12 - Diaphragm cut-off apparatus, e.g. with a member deformed, but not moved bodily, to close the passage with flat, dished, or bowl-shaped diaphragm
• F16K 7/17 - Diaphragm cut-off apparatus, e.g. with a member deformed, but not moved bodily, to close the passage with flat, dished, or bowl-shaped diaphragm arranged to be deformed against a flat seat the diaphragm being actuated by fluid pressure
