    Abstract: An exemplary method for making a micropump device is disclosed as providing inter alia a substrate (300), an inlet opening (310), and outlet opening (340), a pump chamber (370) and flapper valves (350, 360). The fluid inlet channel (310) is generally configured to flow a fluid through/around the inlet opening flapper valve (350). The outlet opening flapper valve (360) generally provides means for preventing or otherwise decreasing the incidence of outlet fluid re-entering either the pumping cavity (370) and/or the fluid inlet channel (310). Accordingly, the reduction of backflow generally tends to enhance overall pumping efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming gas/liquid micropumps that may be readily integrated with existing portable ceramic technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.

    Abstract: A field emission display (100) includes a dielectric layer (132) having a plurality of emitter wells (134), a plurality of electron emitters (136) disposed one each within the plurality of emitter wells (134), a plurality of conductive rows (138, 140, 142) disposed on the dielectric layer (132) and having sacrificial portions (154), and ion shield (139) disposed on the dielectric layer (132) and spaced apart from the sacrificial portions (154) of the plurality of conductive rows (138, 140, 142), and an anode (121) opposing the plurality of electron emitters (136) and defining a projected area (122) at the plurality of conductive rows (138, 140, 142). The sacrificial portions (154) of the plurality of conductive rows (138, 140, 142) extend beyond the projected area (122) of the anode (121).

    Abstract: A method for reducing charge accumulation in a field emission display (100) includes the steps of causing a plurality of electron emitters (114) to emit electrons (132) to reduce the potential at an anode (124) of the field emission display (100). Upon the reduction of the potential at the anode (124), the electrons (132) neutralize a positively electrostatically charged surface (129) of a spacer (130). The anode potential is dropped by providing a resistor (127) in series with a voltage source (126) connected to the anode (124). The anode potential is reduced by causing the electron emitters (114) to emit simultaneously to provide a pull-down current (128) at the anode (124). The voltage at the anode (124) is reduced to a value that causes a sufficient flux of electrons (132) to be attracted to the charged surfaces (129) for neutralizing them.
