  • Fluid ejector device
    Patent number: 8042908
    Abstract: A fluid ejector device, including: a fluid nozzle layer defining an orifice therein; and at least one epoxy resin layer established on the nozzle layer, the at least one epoxy resin layer having first and second opposed surfaces with a thickness there between and a fluorine gradient formed therein such that the gradient extends into at least a portion of the thickness of the at least one epoxy resin layer, wherein an amount of a fluorinated species present in the at least one epoxy resin layer at the first opposed surface is greater than an amount of the fluorinated species present in the at least one epoxy resin layer at the second opposed surface that is adjacent the fluid nozzle layer.

  • Cantilevers for sensing fluid properties
    Patent number: 7313945
    Abstract: A system for sensing a property of a fluid comprises a fluid channel operable to receive the fluid therein, a flexible arm having a free end positioned within at least a portion of the fluid channel, a fluid actuator disposed sufficiently close to the flexible arm such that actuation of the fluid actuator induces movement of the flexible arm when the fluid is present, and a deflection sensing system operable to quantifiably detect movement of the flexible arm.

  • Fluid ejection device having a layer with a discontinuity
    Patent number: 7024768
    Abstract: In one embodiment, a fluid ejection device comprises a substrate having a first surface, and a fluid slot in the first surface. The device further comprises a fluid ejector formed over the first surface of the substrate, and a chamber layer formed over the first surface of the substrate. The chamber layer defines a chamber about the fluid ejector, wherein fluid flows from the fluid slot towards the to be ejected therefrom. The chamber layer has a discontinuity, wherein the discontinuity is positioned over the fluid slot.
