Latest Patents

One of Lee's latest patents is titled "Three state driver for inductive loads." This invention allows for the use of charge, idle, and discharge states in which a positive voltage, a short, and a reverse voltage are connected across the inductive load. The design utilizes an H-bridge comprising two electronic switches and two diodes to switch the inductive load voltages as commanded by a comparator circuit. This circuit compares the load current to a desired load current, enhancing the efficiency of inductive load management.

Another notable patent is "Method and apparatus for drop-on-demand ink jet printing." This invention introduces a method of ink jet printing that produces drops with a diameter ratio to the internal diameter of their print nozzles of 1:2, deviating from the standard ratio of 2:1. The innovation involves imparting motion to the print liquid through a unique actuation of the print nozzle, which is cocked, released, and abruptly stopped. This technique creates a leading edge on the print nozzle, improving control over drop placement and ensuring precise printing.
