Abstract: 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 (16) which generates energy used to emit the biofluid drops. A reagent cartridge (12) 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.

Abstract: 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.

Abstract: This invention is an acoustic ink printer a pool of ink (33) with a free surface (36). Underneath the ink is a print head (10) which has droplet ejectors (14) for irradiating the free surface (36) of the pool of ink (33) with focused acoustic radiation (44). Over the free surface (36) of the pool of ink (33) is a membrane (16), with an aperture (20) aligned with each droplet ejector (14), in intimate contact with the free surface (36) of the pool of ink (33). The apertures (20) are substantially larger than the waist diameter (46) of the focused acoustic radiation (44). An external pressure source (50) maintains the meniscus (48) of the pool of ink (33) substantially in the focal plane (52) of the focused acoustic radiation (44) during operation of the droplet ejectors (14). A piezoelectric crystal (24) is in intimate contact with the pool of ink (33). An electrical signal source (32) energizes the piezoelectric crystal (24) in order to apply a pressure signal (54) on demand to the pool of ink (33) during operation of the droplet ejectors (14). The different pressure signals (54) resulting from application of different electrical signals (29) to the piezoelectric crystal (24) can be utilized to eject individual droplets (38) of ink (33) from the free surface (34) of the ink (33) on demand, or to effect finer control over the free surface (34) of the ink (33) than is possible with the external pressure source (50) by itself.

Abstract: 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.

Abstract: A droplet emitter with an array of droplet emitting devices constructed such that one flowing liquid is used to create the droplets while a second low acousti c impedance liquid can be used to both make the transfer of acoustic energy to the first liquid more efficient and help maintain a uniform temperature of the droplet emitter array. Both the emission fluid and the low acoustic impedance fluid can be circulated throug h the droplet emitter to allow for excess heat generated by control electronic to be transferred to the flowing. This prevents for instance excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.
