Abstract: The present disclosure relates to an inkjet printing system that includes an inkjet printhead having a plurality of electrical contacts. The plurality of electrical contacts include address contacts and enable contacts for enabling drop generators and drive current contacts for providing drive current to enable drop generators for selectively ejecting ink therefrom. The printing system includes a printing device having a plurality of electrical contacts including address contacts, enable contacts and drive current contacts. The plurality of electrical contacts are configured to establish electrical contact with corresponding electrical contacts on the inkjet printhead upon insertion of the inkjet printhead into the printing device. The printing device provides periodic address signals and enable signals to the address and enable contacts one the printhead. In addition, the printing device selectively applies drive current to accomplish forming images on print media.

Abstract: An ink jet printhead having FET drive circuits that are configured to compensate for power trace parasitic resistances.

Abstract: The present disclosure relates to an inkjet printhead having a plurality of drop generators responsive to drive current and address signals for dispensing ink. The inkjet printhead includes first and second drop generators disposed on the printhead with each of the first and second drop generators configured to receive drive current from a drive current source. Each of the first and second drop generators is configured to receive address signals from a common address source. The inkjet printhead further includes a switching device connected between the common address source and each of the first and second drop generators. The switching device is responsive to enable signals for selectively providing the address signal to only one of the first and second drop generators.

Abstract: The present disclosure relates to an inkjet printhead having a plurality of drop generators that selectively eject ink in response to activation. The inkjet printhead includes first and second drop generators disposed on the printhead. Each of the first and second drop generators are configured for connection to a source of drive current. The inkjet printhead also includes a control device configured for connection to a periodic address signal and first and second periodic enable signals. The control device is responsive to the first periodic enable signal and periodic address signal for enabling the first drop generator for activation in response to drive current. The control device is responsive to the second periodic enable signal and periodic address signal for enabling the second drop generator for activation in response to drive current.

Abstract: An ink jet printhead having a ground bus that partially overlies active regions of FET drive circuits.

Abstract: A housing for fiber optic components reduces stress on optical fibers and protects the components from environmental shock and vibration. The housing includes a protective body having a receiving space wherein the fiber optic component is positioned. A rigid adhesive applied to the fibers in a specific stress reducing profile near the ends of the receiving space secures the component out of contact with the wall of the receiving space without inducing stress on the jacketless optical fibers. A gel support material fills the receiving space surrounding the component and providing vibration isolation. The invention is particularly uses for housing fiber optic couplers which are subject to shock, vibration, and temperature extremes.
