Title: Innovations of Thomas Ogle Shafer
Introduction
Thomas Ogle Shafer is a notable inventor based in Seattle, WA (US), recognized for his contributions to aviation technology. He holds a total of five patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest inventions is the Aviation Datalink Communications Management Unit. This device serves as an interface between aircraft avionics data systems and an antenna. It includes a radio and at least one computing device housed within an enclosure. The radio is connected to the antenna and is designed to transmit outgoing messages while receiving incoming messages. The computing device facilitates the communication process by sending outgoing messages to the radio for transmission and receiving incoming messages from the radio. The radio may function as a very high frequency (VHF) transceiver.
Another significant patent is the Radio Frequency Power Amplifier Protection System. This system is designed to protect a radio's RF power amplifier. It utilizes a resistive tap connected to the drain of a power amplifier transistor along with a high-speed voltage detector. The system conducts short, low-power test pulses to assess the quality of an antenna load when tuning the radio to an RF carrier frequency. If the measured voltage exceeds a calibrated threshold, the RF transmitter's power is reduced or shut down entirely. Additionally, the invention includes a method for detecting when an antenna is disconnected from a radio by measuring the resistance of the antenna using a low-frequency AC signal.
