Title: The Innovations of Daniel M. Seslar
Introduction
Daniel M. Seslar is an accomplished inventor based in Weymouth, MA (US). He has made significant contributions to the field of signal processing, holding 2 patents that showcase his innovative approach to technology. His work primarily focuses on enhancing the performance of electro-acoustic systems.
Latest Patents
One of Seslar's latest patents is a "Signal processing system having a very long time constant." This invention utilizes a switched capacitor integrator within the feedback loop of an automatic gain control (AGC) circuit. It provides a very long time constant of five minutes or more when the amplitude of the gain-controlled signal is within predetermined limits. The time constant can be quickly adjusted to a much shorter value when the signal exceeds these limits, allowing for rapid adjustments to maintain the desired amplitude range. This innovation achieves time constants significantly longer than those possible with prior art methods.
Another notable patent is the "Noise trap circuit," which is particularly suitable for use in electro-acoustic systems. This circuit effectively suppresses low-level signals or noise while allowing larger signals to pass unattenuated. It employs blocking elements that create a high impedance path to noise but switch to a conductive state when large signals are present. Additionally, shunt elements across the output terminals provide a low resistance path when only noise is present, switching to a non-conductive state when large signals are detected.
