Latest Patents

One of Burke's latest patents is titled "Special geometry ink jet resistor for high dpi/high frequency structures." This invention features an inkjet printhead structure that incorporates novel resistor circuitry fabricated on two different substrate layers. The dual-layer circuitry minimizes the required substrate surface area and printhead shelf length, thereby enhancing the printer's operating frequency and print density. In this design, heating resistors are strategically spread across the substrate surface, with conductors attached to opposite ends in a unique configuration. This innovative routing allows multiple heater resistors to share the same conductor return path located on a second conductive layer. Another embodiment of this invention involves trapezoid-shaped heater resistors that ensure uniform heating, while alternative resistor shapes are introduced to maintain consistent heat dissipation despite variances in resistor and conductor sheet resistance.

Another significant patent by Burke is the "Particle tolerant inkjet printhead architecture." This invention aims to reduce particle clogging in ink firing chambers of inkjet printer printheads. The design features a barrier layer with multiple inner barrier islands, each linked to a respective heater resistor, positioned between an ink firing chamber and the ink plenum. This configuration creates two ink feed channels designed with right-angle turns to prevent particles from entering the ink firing chamber. Additionally, outer barrier islands, equal in number to twice the inner barrier islands, are arranged parallel to the heater resistors to further protect the ink feed channels from particle intrusion.
