Title: Frank A Pizzarello: Innovator in Tachometer Systems and Memory Devices
Introduction
Frank A Pizzarello is a notable inventor based in Yorba Linda, CA (US). He holds a total of 5 patents that showcase his contributions to technology, particularly in the fields of tachometer systems and memory devices. His innovative work has had a significant impact on various industries.
Latest Patents
One of Pizzarello's latest patents is a tachometer noise reduction system that utilizes a pickup coil to cancel noise generated by a current-carrying drive coil in a magnetic field. This system allows for the calculation of speed based on the voltage produced by an attached tachometer coil. The noise produced by changes in the drive coil current is offset by combining the tachometer voltage with the voltage from a stationary pickup coil, which captures only the noise. Another significant patent is for an electrochromic nonvolatile memory device. This apparatus is designed for storing and retrieving data through a series of electrochromic cells that can control their illumination transparency. The device includes a voltage source for each cell, a light source for illumination, and a charge transfer device for photodetecting the light that passes through the transparent cells to retrieve stored data.
