Title: The Innovative Mind of James R. Engel in Communication Technology

Introduction

James R. Engel, an accomplished inventor from Sleepy Hollow, IL, has made significant contributions to the field of communication technology. With a portfolio of three patents, Engel's work focuses on improving communication systems through innovative methods and arrangements that minimize transmission collisions and enhance data acknowledgement processes.

Latest Patents

Engel's latest inventions include:

1. **Method and Arrangement for Channel Monitor and Control**: This invention describes a method for controlling transmissions among multiple communication units. It determines an inhibit state based on an inhibit signal and information in a header preceding a coded message. The system ensures that while one remote unit transmits a coded message, all others are prevented from transmitting to avoid collisions. By introducing a random delay before retrying to send a message, Engel's method substantially reduces message-message collisions, better coordinating inbound transmissions to the base station.

2. **Inbound Acknowledgement Stack**: In this data message communication system, specific messages necessitate a return acknowledgement signal. Engel's invention activates whenever an outbound message is received, allowing each portable unit to monitor the communication channel for an active inhibit signal. If the inhibit signal is not active, the unit promptly transmits its acknowledgement message. However, if the signal is active, the unit counts outbound messages requiring an acknowledgement since it received its message. Upon the termination of the inhibit signal, the unit pauses for a unique period before transmitting its acknowledgement signal, enhancing overall communication efficiency.
