摘要： Provided is a priming mechanism for priming a biofluid drop ejection device having a drop ejection opening leading to an ejection reservoir. The priming mechanism includes a vacuum unit which generates a vacuum force, connected to a vacuum nozzle. The vacuum nozzle is located over the drop ejection opening. A disposable sleeve or tubing is attached to the vacuum nozzle and is placed in operational contact with the drop ejection opening. A fluid height detection sensor is positioned to sense a fluid height within at least one of the disposable tubing and the vacuum nozzle. Upon sensing a predetermined fluid height, by the fluid height detection sensor, the priming operation is completed, and the primer mechanism is removed from the operational contact with the drop ejection opening.

摘要： A multiple-ejector system for printing arrays of biofluids include a tooling plate having a plurality of sets of tooling pins extending outward from the surface of the tooling plate. A printed circuit board is provided having pairs of power connection pins and ground return pins extending from a surface of the circuit board. A plurality of biofluid drop ejection units are provided and include alignment grooves and at least a transducer. Each of the plurality of biofluid drop ejection units are connected to a corresponding one of a set of tooling pins by connection of the tooling pins and alignment grooves. The power connection pins of the pairs are in operational connection with respective transducers and the ground return connection pins of the pairs are in operational connection with a body portion of the drop ejection units. The different drop ejection units will contain different biofluids which are to be emitted onto a substrate. Verification of drop ejection units containing biofluids, may be obtained in one embodiment through the use of an optical scanner. Detection of drops at defined locations provides a verification that validates a properly formed spot is present on a substrate, and is in the correct position.

摘要： A biofluid drop ejection unit for ejecting biofluid drops. A biofluid drop ejection mechanism of such a unit includes a transducer, which generates energy used to emit the biofluid drop. Further provided is a reagent cartridge or biofluid containment area which holds the biofluid. The reagent cartridge or biofluid containment area is configured to hold low volumes of biofluid and to avoid contamination of the biofluid. The reagent cartridge or biofluid containment area is in operational connection with the drop ejection mechanism such that upon operation of the drop ejection mechanism, biofluid drops are emitted. The biofluid drop ejection mechanism is a high efficiency device, and may be configured as two separate pieces or as a single disposable unit.

摘要： An acoustic ink printhead has a channel configured to receive ink for printing. The channel has an ink inlet (18) and an ink outlet (20) connected to a recirculating ink pump (14) to promote flow of ink in the channel (26). A plurality of acoustic lenses (28) are positioned adjacent to the channel, with a focal length of at least one of the acoustic lenses differing from focal lengths of the other acoustic lenses to compensate for drop in pressure along the length of the channel. In operation, acoustic energy is directed against the ink surface to cause ejection of individual ink droplets of a predetermined size.

摘要： A droplet ejector (10) for an acoustic printer has an acoustically thin capping structure (12) that permits accurate location of the free surface of a liquid ink (30) to enable acoustically induced ink droplet ejection, and that prevents the ink from spilling from its well. Acoustically thin implies that the capping structure thickness is a small fraction of the wavelength of the applied acoustic energy. One capping structure is a thin wafer of porous silicon placed over the aperture of an ink filled ink well (28). Acoustic radiation pressure pushes liquid ink from the well through the pores (36) so that a thin ink film forms over the capping structure. Another capping structure is a solid membrane placed over the ink well aperture. An ink deposition means (60,90) deposits a thin film of ink over the capping structure. With either structure, applied acoustic energy from a transducer (20) can pass through the capping structure to cause droplet ejection from the free surface of the ink film.

摘要： A printhead for an acoustic ink printer has a piezoelectric transducer (11,12,13) on one surface of a substrate (10). A layer (14) of a dielectric material is provided on the surface of the transducer away from the substrate. A Fresnel lens (15) is formed in the surface of the dielectric layer away from the transducer, for focusing sound energy near the surface of a body of ink adjacent the dielectric layer. A pit (19) may be formed in the substrate under the transducer. The transducer may be a body (12) of piezoelectric material sandwiched between a pair of electrodes (11,13), the lower electrode of which has a thickness that is a quarter wave at the excitation frequency of the transducer. An anti-reflective coating (30) may be provided on the lower surface of the substrate, with a body (31) of an absorptive material abutting the anti-reflective layer, or an absorptive material (32) having an acoustic impedance approximately matching that of the substrate may be coated on the lower surface of the substrate.

摘要： An acoustic ink printer transducer comprises a piezoelectric layer (13) positioned between two suitable electrode materials (12,14). To enable ejection of a number of different ink droplet sizes from the acoustic ink printer, thereby facilitating grey scale printing, the piezoelectric layer (13) and one (14) of the electrode layers have an acoustic thickness of λ/4, where λ is the wavelength at the fundamental resonant frequency ω o of the transducer.
