Title: **Andras I Szabo: Innovator in Sine Wave Generation and Control Systems**
Introduction
Andras I Szabo, an innovative engineer based in Export, PA, has made significant contributions to the field of electronic engineering with a total of 11 patents to his name. His work primarily focuses on sine wave generation and the control systems that enhance operational efficiency in various applications, particularly in the energy sector.
Latest Patents
One of Andras's notable patents is for a **Stable Sine Wave Generator**, which represents a leap forward in precision sine wave generation. This device utilizes a Programmable Read-Only Memory (PROM) to store predetermined bit patterns. These patterns are then converted into pulse waveforms using a stable and accurate clock pulse. The output is finely adjusted to a specific voltage level and filtered through a band-pass filter to produce a stable fundamental frequency sine wave. This technology is particularly valuable in Linear Variable Differential Transformer (LVDT) applications, where it measures the position of controlled objects like turbine valves. Furthermore, the arrangement allows for the generation of sine waves with predetermined phase relationships for diverse control or signal processing needs.
Another of his significant inventions is a **Turbine Valve Control System**. This system employs hydraulically operated turbine steam admission valves, each equipped with its own microcomputer control. In scenarios where a valve becomes stuck due to contamination in the hydraulic system, the microcomputer sends an oscillatory control signal to "dither" the valve. If this method fails, the system provides a control signal of greater magnitude than typically necessary to close the valve, thereby ensuring operational reliability.
