Title: The Innovations of Herbert Dropkin
Introduction
Herbert Dropkin is a notable inventor based in Washington, DC, who has made significant contributions to the field of technology. With a total of 3 patents to his name, Dropkin's work primarily focuses on advanced sensor technology and electronic frequency tuning.
Latest Patents
One of Dropkin's latest patents is the "Random Binary Modulated Sensor." This invention transmits a continuous wave radio frequency signal modulated by a binary random bit pair code signal, which is then transmitted by an antenna. The system is designed to receive a return signal reflected from a target, utilizing a receiver mixer to modulate the return signal with the radio frequency signal. A delay circuit is incorporated to delay the binary random bit pair code, while a correlator processes the modulated return signal to produce a Doppler output signal. Additionally, a separate radio frequency path is included to cancel noise signals generated by antenna mismatch during transmission.
Another significant patent is the "Wideband Electronic Frequency Tuning for Otrons." This invention pertains to an orotron that generates near millimeter wavelength radiation at a selectable output frequency within a wide frequency range. The orotron's output power is automatically tuned electronically at the selected output frequency. A piezoelectric electromechanical positioning device is employed to adjust the mirror separation in accordance with a position control signal. The electron beam acceleration voltage, which determines the orotron output frequency, is adjusted simultaneously with the position control signal to maintain the output power at a single oscillation mode over a wide frequency range.
