摘要： A method of ejecting a droplet of a fluid from a surface of the fluid includes the step of generating an acoustic wave to eject the droplet from the fluid surface. The acoustic wave is shaped into an optimal toneburst such that the droplet is ejected substantially in a direction of acoustic wave propagation substantially independent of an orientation of the fluid surface.

摘要： To correct for blooming artifacts in an ionographic imaging device, a summation of the effects of previously deposited charge is made prior to depositing ions to form the image, to determine the likely amount of displacement of any ion due to a previously deposited charge. A comparison of the displaced pixel position, with the desired image is made to determine where the ions will fall. If the ions are predicted to fall within an area in which ion deposition is desired, ions are allowed to pass to the imaging surface. If the comparison of the displaced pixel position with the desired image is made and predicts that ions will fall outside of an area in which charge is desired, ions are prevented from passing to the image surface.

摘要： A method for the situ measuring of a sample of a porous material having a gaseous fluid and fine granular material located within its pores and, in particular, for determining the concentration of the fine granular material within the sample. The method includes the steps of generating a first acoustic wave signal of known amplitude and phase velocity, directing the first acoustic wave signal through the sample, receiving a second acoustic wave signal representing the first acoustic wave having passed through the sample, and determining the concentration of the fine granular material in the sample from the changes between the first acoustic wave signal and the second acoustic wave signal.

摘要： A heater for an ionographic marking apparatus including a housing, means for generating a supply of marking ions within the housing, means for transporting the marking ions through and out of the housing, and an array of modulation electrodes upon a substrate for controlling the transport of ions out of the housing, the modulation electrodes being spaced from one another by electrically insulating regions. The heater is associated with the array for raising the temperature of the electrically insulating regions so as to prevent the condensation of moisture thereon.

摘要： A method of determining the volume or height of fluid in a reservoir is provided. A first burst of focused acoustic energy is used to raise temporarily a protuberance on a free surface of the fluid. A second burst of acoustic energy is directed to the free surface of the fluid. Echoes from the second burst of acoustic energy are detected. The detected echoes are employed to compute the height of the fluid.

摘要： The present invention provides a method and device for the acoustic ejection of fluid droplets from fluid-containing reservoirs using focusing means having an F-number greater than approximately 2. The droplets are ejected toward designated sites on a substrate surface for deposition thereon. In one embodiment, the device is comprised of: a plurality of reservoirs each adapted to contain a fluid; an ejector comprising a means for generating acoustic radiation and a large F-numbered means for focusing the acoustic radiation at a focal point near the fluid surface in each of the reservoirs; and a means for positioning the ejector in acoustically coupled relationship to each of the reservoirs. The invention is useful in a number of contexts, particularly in the preparation of biomolecular arrays.

摘要： A method and apparatus which laterally focuses aqueous ink drops onto a substrate, using electric fields. The drops are not charged, and focusing results from the forces on the uncharged dielectric drop that occur in a nonuniform electric field. It is shown that initial lateral velocity misdirection of the drops is corrected using electric fields. Lateral velocities which would produce drop displacements of ˜50 &mgr;m from their intended positions, at a height of 1 mm above the ink surface, may be corrected to produce displacements of less than 2.5 &mgr;m.

摘要： A captured image includes a portion of a set of two-dimensional address codes. The portion of address codes can be decoded to determine a discrete pointer uniquely defining the portion. The captured image is first processed to determine the orientation of the portion, and then decoded based on the orientation to determine the discrete pointer. To determine the orientation of the portion, the portion is first analyzed to determine values at discrete locations within the portion. The values at each location form a matrix of binary data. The values of the matrix are then correlated to determine an orientation of the captured portion of two dimensional address codes. After determining the orientation of the portion, the values can be further analyzed to determine a discrete pointer that identifies the location of the portion within the address space defined by the two-dimensional address codes.

摘要： A self-clocking glyph code is provided for encoding n-bit long digital values (where n>1) in a logically ordered sequence of composite glyphs that are written, printed, or otherwise recorded on a hardcopy recording medium in accordance with a predetermined spatial formatting rule. As used herein, a "composite glyph" is a graphical symbol that has a plurality of predefined, substantially orthogonal, graphical characteristics; each of which is capable of assuming any one of a plurality of predefined graphical states. An n-bit long digital value is distributively encoded in a glyph of this type by decomposing its n-bits, prior to or during the encoding, into a plurality of shorter, ordered, non-overlapping bit strings. The digital values of these bit strings, in turn, are encoded in the states of respective graphical characteristics of the composite glyph in a predetermined logical order, thereby preserving the logical ordering of the bit strings.
