Patents by Inventor Matthew Giere

Matthew Giere has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Segmented resistor inkjet drop generator with current crowding reduction
    Patent number: 6367147
    Abstract: In order to overcome inefficient power dissipation in parasitic resistances and to provide economies in the power supply, a higher resistance value heater resistor is employed in a thermal inkjet printhead. Higher current densities in a high resistance segmented heater resistor are reduced by employing a shorting bar divided by a current balancing resistor.
    Type: Grant

  • Electrostatic discharge protection of electrically-inactive components in a thermal ink jet printing system
    Patent number: 6361150
    Abstract: This present invention is embodied in a system and a method for protecting an electrically-inactive component of a microsystem from an ESD event. The invention includes embodiments that protect the microsystem from ESD events that directly strike an electrically-inactive component and that are external to the electrically-inactive component. The present invention includes an ESD dissipation device having a connected chain of electrically-inactive components that are electrically floating. Alternatively, the electrically-inactive components can be held at the same potential as an electrical component. Further, a sacrificial ESD breakdown device is included that provides a preferential ESD breakdown site away from the protected component. Also, capacitively coupled thin-film layers can provide shielding to electrically-inactive components.
