Title: The Innovations of Loren B Johnston
Introduction
Loren B Johnston is a notable inventor based in Princeton, NJ (US). He has made significant contributions to the field of electron gun technology, holding a total of five patents. His work has advanced the understanding and functionality of electron guns, which are crucial components in various electronic devices.
Latest Patents
Johnston's latest patents include a "System for segmentally refreshing the stored electron gun drive voltages." This innovative system allows for the sequential refreshing of segments of stored voltage characteristics of electron guns through a clock gate mechanism. The clock gate facilitates the passage of clock pulses to a counter, which refreshes the stored voltage signals. After a predetermined number of counts, the counter inhibits the clock gate until a vertical blank pulse re-enables it, allowing the counter to resume its function.
Another significant patent is the "System for compensating for transfer characteristic variations." This invention precisely establishes the minimum output level of an electron gun driven at discrete voltage levels. A target value, slightly above the minimum voltage level, is compared with the actual output. The result of this comparison is utilized to uniformly establish the minimum electron gun drive voltage, compensating for variations within the gun drive circuitry. An additional circuit can also be employed to establish the maximum output level of the electron gun.
