Latest Patents

Horst Schaefer holds a patent for an "Amplitude Stabilized Oscillator Circuit." This oscillator circuit is designed to stabilize the amplitude of high-frequency oscillations of audio signals. The circuit allows an audio signal with a frequency range of 20 Hz to 20 kHz to be modulated with a high frequency and emitted as an RF audio signal exceeding 2 MHz. This technology is particularly useful in infrared transmitting units, where low-frequency audio signals are transformed into higher frequency infrared signals. The higher frequency audio signals can then be transmitted via infrared channels to receiving units, such as infrared headphones, which include demodulators and stereo decoders to reproduce the original low-frequency audio signals.
