Latest Patents
One of Dennis H Pengelly's notable patents is titled "Piezo impulse ink jet pulse delay to reduce mechanical and fluidic." This patent describes an ink jet apparatus that comprises an array of impulse ink jets. Each ink jet includes a chamber with an orifice and a transducer coupled to the chamber. A signal generator applies firing signals to each transducer, allowing for the ejection of ink droplets on demand. The controller manages the phase of the firing signals to prevent simultaneous application to adjacent ink jets, thereby enhancing performance. The design ensures that the orifices are linearly aligned, with adjacent ink jets producing ink drops offset by less than the diameter of the drops. The patent also addresses the natural ringing of the piezo crystals, which occurs at a frequency of about 46 kHz, by implementing a delay of approximately 25 ms to minimize cross-talk among neighboring channels. This innovation has the potential to improve the efficiency and quality of ink jet printing.
