  • Patent number: 9555631
    Abstract: Laminate manifolds, and their manufacture. The laminate manifolds (18) include plates (20) arranged in parallel, forming a laminate plate stack (22), with a securing agent (24) securing the plates in the plate stack. At least some of the plates incorporate apertures (26) that are oriented in their respective plates so that when the plates are arranged in the laminate plate stack (22), the apertures define a fluidic pathway (28) that emerges from the laminate plate stack between parallel plates. The laminate manifolds are particularly useful as ink manifolds (14) for inkjet printers (10).

  • Patent number: 8619012
    Abstract: A display element (100) corresponds to a pixel of a display. The display element includes a top electrode (102) connected to a first addressable line of the display, and a bottom electrode (104) connected to a second addressable line of the display. The display element includes a display mechanism (106) situated between the top electrode and the bottom electrode and having a number of individually turned-on steps. Each individually turned-on step has a turn-on voltage threshold at which the step is turned on upon a voltage applied between the top and the bottom electrodes equal to or greater than the turn-on voltage threshold. Each individually turned-on step has a turn-off voltage threshold at which the step is turned off upon a voltage applied between the top and the bottom electrodes equal to or less than the turn-off voltage threshold.

  • Patent number: 8232960
    Abstract: Among various embodiments of the present disclosure, displaying electrophoretic particles can be performed by configuring an electrophoretic display for directed spreading of electrophoretic particles across a number of substantially planar display electrodes. Such a configuration can be accomplished by controlling planar spreading of the electrophoretic particles in an electrophoretic pixel with an electrical field between an in-plane storage electrode and an in-plane activation electrode. The in-plane activation electrode can be connected to an in-plane display electrode, which extends across a first area in the electrophoretic pixel adjacent to a display aperture having a second area that is substantially coextensive with the first area.
