Title: Innovations of George R Spencer
Introduction
George R Spencer is a notable inventor based in Needham, MA (US). He has made significant contributions to the field of technology, particularly in radar signal processing. With a total of 8 patents to his name, Spencer's work has had a profound impact on various applications.
Latest Patents
One of his latest patents is a frequency adjusting arrangement. This invention discloses a circuit for compensating for frequency modulation on a radar signal. The circuit includes an adaptive narrow band filter in the feedback path of a phase-locked detector. This filter has a bandwidth that is narrower than the frequency range of the signal being compensated. Additionally, it includes means for detecting the amplitude of such a signal. This invention was developed under a contract with the Department of Defense. Another significant patent is the phase lock loop circuitry. This arrangement reduces the effect of vibration-induced changes in phase of the first local oscillator in a tracking receiver. The final detection is accomplished by a synchronous detector in a phase lock loop that incorporates a voltage-controlled oscillator. The design includes a differentiator that provides a control signal whenever a vibration-induced change occurs. This control signal minimizes the time taken for the voltage-controlled oscillator to regain proper phase.
