Title: The Innovations of John F. Smith

Introduction

John F. Smith is a notable inventor based in Warminster, PA (US). He has made significant contributions to the field of navigational communications, holding a total of 5 patents. His work has been instrumental in advancing technology in this area.

Latest Patents

One of his latest patents is a Portable Navigational Communications Transceiver. This innovative device is designed to be handheld and is compressed into a case with a volume of about 37 cubic inches. It defines functional implementation for VOR (VHF omni-directional range) navigation. The transceiver can be selectively switched to process and display directional radial information. A microprocessor circuit provides primary circuitry information in combination with transceiver function software held in ROM (read-only memory). Additionally, a plurality of pre-programmed frequencies may be selected.

Another significant patent is the Automatic Squelch Circuit with Hysteresis. This radio receiver squelch circuit operates by comparing the audio component level of the detected signal with the noise component level. It amplifies and passes signals when the audio component exceeds the noise component by a predetermined ratio. Conversely, it shunts the signals, squelching any output when the noise component exceeds the audio component by a predetermined ratio. The circuit incorporates a hysteresis function, ensuring that the audio level required to initiate squelch is less than that required to break squelch.
