摘要： Methods and apparatuses are provided for depositing a material on a surface. In accordance with the method a stream of a component material is formed having formed printing and non-printing droplets and satellite droplets of the material. The stream is directed at the surface. A deflecting energy is applied to separate printing droplets from non-printing droplets in the stream, so that only printing droplets travel to the surface. The deflecting energy is adapted to direct non-printing droplets for non-printing drop collection, and to direct at least a portion of the satellite droplets to be controlled in a manner adapted to prevent the material in the satellite droplets from reaching the surface, so that less than all of the material in the satellite droplets reaches the surface. Articles are also provided having limited satellite material.

摘要： The present invention resides in a self-cleaning printer with a print head having an orifice plate defining an ink jet orifice, a cleaning orifice and a drain orifice. The orifice plate further defines an outer surface between the orifices. A source of pressurized cleaning fluid is connected to the cleaning orifice and a fluid return is connected to the drain orifice for storing used cleaning fluid. A cleaning surface is disposed adjacent to and separate from the outer surface to define a capillary fluid flow path from the cleaning orifice across the ink jet orifice and to the drain orifice. During cleaning, the source of pressurized cleaning fluid discharges a flow of a cleaning fluid into the capillary fluid flow path and pressurized cleaning fluid from the capillary flow path passes through the drain orifice and into the fluid return.

摘要： A pump(10) for pumping various primary fluids includes a body(100) having a primary fluid channel(110) defined therein, and a primary fluid supply is coupled to the primary fluid channel to supply a primary fluid to the primary fluid channel. A mechanism(130/132) is provided for introducing a secondary fluid to an interface region of the primary fluid channel to thereby define a fluid interface between the primary fluid and the secondary dry fluid in the interface region. An energy delivery(150/160) device delivers energy to the interface region to create a thermal gradient along the fluid interface. The thermal gradient results in a surface tension gradient along the interface. The primary fluid will move to compensate for the surface tension gradient.

摘要： According to one embodiment of the present invention, a print head comprises a print head body defining an interior chamber and an orifice plate. The orifice plate has an outer surface and further defines a cleaning fluid orifice through the orifice plate for conducting a flow of a cleaning fluid through the cleaning fluid orifice and onto an outer surface of said orifice plate. The orifice plate also defines a drain orifice for conducting a flow of cleaning fluid from the surface to the interior chamber. A supply of pressurized cleaning fluid is disposed in said cavity and connected to the cleaning fluid passageway. During cleaning operations, the fluid flow system defines a flow of a cleaning fluid from the passageway and onto said outer surface. The drain orifice receives cleaning fluid from the outer surface and channels the cleaning fluid into the fluid return.

摘要： An electrostrictive micro-pump is provided for controlling a fluid flow through a cannula or other narrow liquid conduit. The micro-pump includes a pump body having a passageway for conducting a flow of fluid, a pump element formed from a piece of viscoelastic material and disposed in the passageway, and a control assembly coupled to the viscoelastic material for electrostatically inducing a peristaltic wave along the longitudinal axis of the pump element to displace fluid disposed within the pump body. The control assembly includes a pair of electrodes disposed over upper and lower sides of the pump element. The lower electrode is formed from a plurality of uniformly spaced conductive panels, while the upper electrode is a single sheet of conductive material. A switching circuit is provided for actuating the conductive panels of the lower electrode in serial, multiplex fashion to induce a peristaltic pumping action.

摘要： An electrostrictive micro-valve is provided for modulating a fluid flow through a cannula or other narrow liquid conduit. The micro-valve includes a valve body having a passageway for conducting a flow of fluid, a valve element formed from a piece of viscoelastic material and disposed in the passageway, and a control assembly coupled to the viscoelastic material for electrostatically controlling the shape of the material to open or close the passageway. The valve element has a flat lower side connected to an inner wall of the passage of the valve body, and an upper side which faces an opposing wall within the passageway. The control assembly includes a pair of electrodes disposed over the upper and lower sides of the valve element. The electrode facing the lower side of the element is patterned so that localized electrostatic forces are generated across the viscoelastic material when a voltage is applied across both electrodes. Localized electrostatic forces generate a sinusoidal ripple throughout the viscoelastic material forming the valve element whose peak portions act as obstructions throughout the valve body that partially or completely obstruct a fluid flow.
