Hinge

A hinge has a sleeve and a shaft and is mounted between a cover and a base of an electrical device. The sleeve is hollow, is attached to the base and has an internal diameter. The shaft is attached to the cover, is mounted pivotally in the sleeve and has a hollow torsion rod. The torsion rod has an external diameter, an opening end and multiple slots. The external diameter of the torsion rod is bigger than the internal diameter of the sleeve to provide friction. The slots are formed in the torsion rod without communicating with the opening end to provide uniform friction. Because the torsion rod is hollow to provide spaces for the torsion rod to be deformed, the torsion rod maintains its shape. Therefore the torsion rod provides uniform friction with the sleeve.

Electrohydrodynamic (EHD) fluid mover with collector electrode leading surface shaping for spatially selective field reduction

In various electrohydrodynamic (EHD) fluid mover designs disclosed herein, electric field strength may be locally reduced in peripheral regions of an emitter-to-collector electrode gap. As a result, detrimental accumulations of silica, dust and other airborne contaminants can be reduced on surfaces in such peripheral regions, which may otherwise be susceptible to accumulations and / or difficult to clean or condition. In some cases, localized reduction in electric field near sidewall surfaces can provide desirable localized reductions in susceptibility to contaminant related spark or shunting current paths. In some cases, such as when a field blunting structure is employed and (as a result) a generally more uniform electric field pattern is provided locally, an engineered or purposeful local reduction both electric field strength and ion generation in peripheral regions of an emitter-to-collector electrode gap may be quite desirable.
