Latest Patents

Erni holds a patent for a "Disposable Ink Jet Head." This thermal ink jet head integrates jetting resistors, fluid interconnections, an ink reservoir, electrical connections, and jetting orifices into a single unit. The design aims to provide an inexpensive and disposable jetting head. The hydraulic ink system is sealed to prevent user interaction with the liquid ink, allowing ink to exit only through the jetting orifices when activated by the jetting resistors. Once the ink is depleted, users can easily dispose of the old head and install a new one by making a simple mechanical and low voltage electrical connection. He has 1 patent to his name.
