Title: Dennis P Colin: Innovator in RF Amplification and Musical Instruments
Introduction
Dennis P Colin is a notable inventor based in Beverly, MA (US). He holds 2 patents that showcase his contributions to the fields of radio frequency amplification and electronic musical instruments. His innovative designs reflect a deep understanding of both technology and user interaction.
Latest Patents
One of his latest patents is the "Full wave, self-detecting differential logarithmic RF amplifier." This logarithmic RF amplifier features multiple cascaded stages, each containing a differential amplifier that performs full-wave rectification of the RF signal. It includes a circuit that provides a video signal representative of the full-wave rectified RF signal. The amplifier is designed to supply RF signals of equal amplitude and opposite polarity to the inputs of the first differential amplifier stage. Additionally, it sums the video signals from each stage to provide a logarithmic video output. This amplifier is noted for its extremely fast pulse response and clean limiting.
Another significant patent is the "Touch sensitive polyphonic musical instrument." This device is associated with at least one key of an electronic musical instrument, such as an electronic organ. It incorporates a layer of pressure-responsive, variable conductance material that exhibits a switching action when subjected to pressure beyond a threshold. Any increase in pressure thereafter results in an increase in conductance up to a saturation pressure. This device can function as a combined switch and amplitude control or be used with capacitors to provide either a high-pass or low-pass touch-control audio filter. In a fully polyphonic instrument, a tone generator and touch-control filter are linked to each key depression, with the output signal from each activated filter being coupled to audio mixer circuitry.
