  • Patent number: 7442180
    Abstract: Bioactive agents are dosed by a jet dispenser using inkjet technology, such as that used in printing devices. The jet dispenser dispenses precise amounts of bioactive agent into a fluid manifold, in which the bioactive agent can be mixed with an infusion liquid for infusing into a patient. A controller may control delivery of one or more drugs, timing of drug administration, or change drug regimens in response to a changing medical condition of a patient. A drop detector can be used to detect various characteristics of the droplets of the bioactive agent dispensed by the jet dispenser and provide a feedback signal to the controller to determine whether a detected characteristic satisfies a predetermined condition. Methods for administering bioactive agents using a jet dispenser also are disclosed.

  • Patent number: 6840421
    Abstract: A tool is provided that has a grasper adapted to selectively grasp a tearable medium, a conveyer adapted to selectively move the grasper along an axis to move the tearable medium against a tear-off edge to sever the tearable medium, and a controller adapted to transmit a first signal for instructing the conveyer to move the grasper and a second signal for instructing the grasper to grasp the tearable medium.

  • Patent number: 6698863
    Abstract: Apparatus and methods of cleaning the nozzle area and the ink nozzle of a print head of an inkjet imaging apparatus include devices of moving the nozzle area into contact with an imaging media, wherein the nozzle area is moved relative to the imaging media to thereby scrub contaminants and the like from the nozzle area and the ink nozzle. The is accomplished by way of an actuating mechanism that can be configured either to move the print head or to move a backup object which, in turn, moves the imaging media. The print head can be configured to spray ink onto the imaging media just prior to bringing the nozzle area and imaging media into contact with one another, wherein the wet ink can have a solvent effect during the scrubbing of the nozzle area against the imaging media.

  • Patent number: 6609776
    Abstract: A customized font based on fixed font cells having certain non-printable pixels along its perimeter, and formed by a pixel grid having a higher dpi horizontal resolution as compared to its vertical resolution. By preventing any marking dots on adjacent pixels in a given row, a minimal amount of ink drops can be used to print digitized characters, and higher throughput is obtained by using a printhead having a nozzle pitch which is the same as the vertical print resolution, and which has a swath width which allows a complete row of character cells to be printed in a single pass of the printhead across the media.
