Title: The Innovations of John P Wendler
Introduction
John P Wendler is a notable inventor based in Stowe, MA (US). He has made significant contributions to the field of digital audio transmission and mixer circuitry. With a total of 6 patents to his name, Wendler's work showcases his expertise and innovative spirit.
Latest Patents
One of Wendler's latest patents is titled "Simulated degradation of SNR in decoded digital audio correlated to wireless link bit-error rate." This invention provides a system, apparatus, and method for an audible indicator of the quality of a received digital radio transmission. After receiving a digital radio transmission in a digital radio receiver, the quality of the transmission is detected. An audible communication from the received transmission is then decoded, and an audible indicator is superimposed onto this communication to form a composite audible signal. The amplitude of the audible indicator is dynamically adjusted relative to the amplitude of the audible communication, based on the quality of the received transmission.
Another significant patent is for "Heterojunction bipolar mixer circuitry." This invention involves mixer circuitry that has a semiconductor body formed therein. The mixer circuitry includes an oscillator with a heterojunction bipolar transistor and a mixer with a Schottky diode. The heterojunction transistor has a collector region formed in one portion of a doped layer of the semiconductor body, while the diode has a metal electrode that forms a Schottky contact with another portion of the doped layer. The mixer also includes a diode and a DC biasing circuit, which comprises a constant current for biasing the diode to a predetermined operating point that remains substantially invariant with the power of an input signal fed to the mixer.
