Title: Innovations of James M Spencer, Jr.
Introduction
James M Spencer, Jr. is a notable inventor based in Phoenix, AZ (US). He holds 2 patents that showcase his contributions to the field of cathode ray tube (CRT) technology. His work has significantly impacted the performance and efficiency of CRT displays.
Latest Patents
One of his latest patents is the "Dynamic convergence control apparatus for shadow mask CRT displays." This invention provides precise convergence compensation in shadow mask type color CRT displays. The apparatus utilizes both coarse and fine compensation methods to ensure accurate display performance. Coarse compensation is achieved through primary polynomial terms in an analog format, while fine compensation is managed by digital programmable read-only memories. The fine compensation values are converted to an analog format using a digital-to-analog converter, which is then applied to the convergence correction coils of the CRT.
Another significant patent is the "Power on demand beam deflection system for CRT displays." This invention features a linear beam deflection system capable of operating over a wide range of beam deflection rates. It includes automatic power supply voltage switching to maintain linear operation and minimize power dissipation. The system continuously monitors the yoke voltage and adjusts the power supply voltage accordingly, ensuring optimal performance.
