Latest Patents

One of Dewey's latest patents is a **method and apparatus for registering color in a printing press**. This innovative method aids in determining color registration within a multi-color printing press that houses several printing stations. It involves creating a process black registration mark in a defined area by positioning multiple color registration marks over one another. By ensuring the black registration mark is placed within the targeted part of the image that is intended to be printed black, adjacent to the black ink image, the identified area can be thoroughly examined to verify the proper positioning of the mark.

Another significant patent involves a **method for increasing the speed of an alternating current motor**. This motor control method utilizes an adjustable frequency power supply, allowing for the selective variation of frequency supplied to the motor. While the motor maintains a constant speed based on the frequency, the current supplied to it is sensed, producing an actual current signal. This signal is compared against a reference current signal that represents a maximum load, enabling adjustments to the supplied frequency to increase motor speed, thus enhancing performance.
