Title: **Innovative Contributions of Simon Makar**
Introduction
Simon Makar, an accomplished inventor based in Macomb, MI, has made significant contributions to the field of technology through his innovative patents. With a total of two patents to his name, Simon's work primarily focuses on cutting-edge solutions for noise suppression and efficient fuel injector systems.
Latest Patents
Simon Makar's latest innovations include:
1. **Drive circuit, device, and method for suppressing noise** - This patent utilizes a low-frequency PWM-modulated signal in conjunction with a high-frequency, unmodulated signal. The method generates a high-frequency PWM-modulated signal directly employed for driving an output stage of a device designed for noise suppression. A microcontroller, equipped with an A/D converter, provides the low-frequency and high-frequency signals, making it capable of producing a PWM output signal with the required high resolution for effective loudspeaker operation.
2. **End of valve motion detection for a spool control valve** - This patent describes a fuel injector system that calculates filtered first and second derivative signals from an unpowered spool valve coil signal. When the spool valve reaches the end of travel, either in the open or closed position, a flat slope is generated on the falling edge of the bell-shaped signal. The second derivative assists in determining the occurrence of the steep slope, enabling a comparator to identify when the spool valve has reached the end of its travel.
