Patent number: 7517043Abstract: Various fluidic techniques can employ ducting structures, such as microstructures, that extend between other components, such as plate-like structures. A ducting structure can, for example, include an inlet opening toward or near one plate-like structure, an outlet opening toward or near another plate-like structure, and a duct in which fluid flows after being received through the inlet opening and before being provided through the outlet opening. In some implementations, a ducting structure is photo-defined, such as by exposing a photoimageable structure and then removing either exposed or unexposed regions. In some implementations, a ducting structure is a freestanding polymer microstructure. In some implementations, ducting structures are microstructures that extend approximately the same length between first and second plate-like structures, and have a ratio of length to maximum cavity diameter of approximately two or more.Type: GrantFiled: December 16, 2004Date of Patent: April 14, 2009Assignee: Xerox CorporationInventors: John S.

Patent number: 6283580Abstract: A method of operation of an acoustic droplet emitter with an array of droplet emitting utilizing high liquid flow rates. The higher flow rates prevent excess heat absorption during the droplet emission process and allow for excess heat generated by control electronics to be transferred to the flowing liquid after droplet emission but before it leaves the droplet emitter. This prevents excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.Type: GrantFiled: July 23, 1999Date of Patent: September 4, 2001Assignee: Xerox CorporationInventors: Joy Roy, Michael C.
