Latest Patents

Among his most notable inventions is the patent for "Resonator sensors employing piezoelectric benders for fluid property." This innovative technology utilizes piezoelectric benders to sense fluid viscosity and density. The benders are submerged in the liquid being monitored, and an input voltage is applied, causing vibrations at a resonant frequency. The output voltage amplitude or frequency is then monitored to assess changes in viscosity and density. This device not only functions as a liquid level sensor but also plays a vital role in controlling fluid viscosity, particularly in applications such as inkjet printing.

Another significant patent authored by Anderson is the "Method and apparatus for automatic setting of nozzle drive voltage in an inkjet printer." This invention provides an accurate methodology for determining and setting the optimal nozzle drive voltage for inkjet printers. By monitoring the current carried by charged test drops through a sensing electrode and ammeter while varying the nozzle drive voltage, Anderson's device creates a plot of drop current versus nozzle voltage. This technique allows for precise calibration of a new nozzle or ink in printers, ensuring optimal performance within the desired printing parameters.
