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: 6740530Abstract: Methods for testing proper operation of drop ejection units in a multi-ejector system are provided to determine whether the drop ejectors have been properly filled and/or the ejectors are emitting fully formed droplets. The methods include testing the ejectors prior to drop ejection. In this method, a priming system is used wherein fluid received by the priming system is ejected onto a test substrate to allow a scanner to determine the existence of the fluids at selected locations. The selected locations are correlated to the drop ejection units to determine which ejection units do not have biofluid or sufficient biofluid. A further method allows for ejection prior to printing, on a test substrate wherein testing for both the fullness of the ejector units as well as proper emission of the ejectors of droplets may be tested. The ejectors after being primed, eject the biofluids which are then scanned and correlated to each individual ejector.Type: GrantFiled: November 22, 2000Date of Patent: May 25, 2004Assignee: Xerox CorporationInventors: Richard H. Bruce, Scott A. Elrod, Jaan Noolandi, David A. Horine, Babur B. Hadimioglu

Patent number: 6694817Abstract: The cantilever of a probe-based metrology instrument such as an AFM is deflected by directing a beam of ultrasonic energy at the cantilever to apply ultrasonically generated acoustic radiation pressure to the cantilever. The energy is generated by an ultrasonic actuator such as a ZnO transducer driven by a power source such an RF signal generator. The transmitted beam preferably is shaped by focusing, collimation, or the like so that it impinges at least primarily on a region of interest of the cantilever such as the free end. The ultrasonic actuator produces a much better controlled force on the cantilever than can be achieved through the use of a traditional piezoelectric actuator and, accordingly, produces a response free of spurious effects (at least when the cantilever is operating in liquid). It also has a frequency bandwidth in the MHz range.Type: GrantFiled: March 12, 2002Date of Patent: February 24, 2004Assignee: Georgia Tech Research CorporationInventors: F. Levent Degertekin, Abidin Guclu Onaran, Babur B. Hadimioglu

Patent number: 6623700Abstract: A level control mechanism is provided for a biofluid drop ejection device which ejects biofluid drops in small volumes. The biofluid drop device includes a drop ejection mechanism having a transducer which generates energy used to emit the biofluid drops. A reagent cartridge or biofluid holding area holds a biofluid, isolated from the drop ejection mechanism to avoid contamination between the biofluid drop ejection mechanism and the reagent cartridge. The reagent cartridge is connected to the drop ejection mechanism such that upon operation of the mechanism, the biofluid is emitted in controlled biofluid drops. A level sensor is positioned to sense a height of the biofluid within the cartridge. Upon sensing the height of the biofluid below a certain level, an adjustment is made to the height by providing at least one of additional biofluid to the cartridge, and raising the level of the entire reagent cartridge.Type: GrantFiled: November 22, 2000Date of Patent: September 23, 2003Assignee: Xerox CorporationInventors: David A.

Publication number: 20030052931Abstract: An at least two-pass acoustic printing system uses an acoustic printhead having an array of ejectors arranged in rows and columns. Operation of each ejector is individually controllable. To minimize cross-talk errors a first selected ejector in a selected row is identified as an odd ejector of the selected row. Thereafter a first firing sequence of the first selected ejector is generated based on the first selected ejector being identified as odd. Then a second ejector, immediately adjacent the first ejector, is selected and is identified as an even ejector. Thereafter a second firing sequence is generated for the second selected ejector based on the selector being identified as even. The first and second firing sequences result in the first ejector and the second ejector being active during non-concurrent time periods. When a defective ejector of the array is detected, an operable ejector firing to the same substrate area is determined.Type: ApplicationFiled: September 12, 2001Publication date: March 20, 2003Applicant: XEROX CORPORATIONInventors: Babur B.
