Latest Patents
One of Osburn's latest patents is titled "Method and apparatus for tuning and aligning an FM receiver." This invention describes a system that compensates for mismatches in component values between the antenna and RF amplifier tuned circuits. It also addresses the IF offset between the local oscillator frequency and the center frequencies of the antenna and RF resonant circuits by developing independent tuning signals for these circuits. Additionally, the system provides temperature compensation and allows for alignment without the need for mechanical adjustments to inductors or capacitors.
Another significant patent is the "Power limiting audio amplifier temperature protection circuit." This invention includes circuitry that detects clipping in an audio amplifier and adjusts the gain of the amplifier input element to control this clipping during closed-loop operation. The system senses the temperature of an amplifier component and modifies the amplifier bias voltage to manage the maximum non-clipping voltage. This innovative approach helps to reduce power dissipation and maintain optimal temperature levels, ensuring minimal disruption to the music reproduction process.
