Title: The Innovations of Andrew W. Barnhart

Introduction

Andrew W. Barnhart is a notable inventor based in Gaithersburg, MD (US). He holds a total of 5 patents that showcase his contributions to the field of communications technology. His work primarily focuses on bandwidth control mechanisms and power control systems for communication channels.

Latest Patents

One of his latest patents is the "Available Bandwidth Control Mechanism." This invention presents an approach for controlling bandwidth allocations for a switching system with transmission constraints. A scheduler within the switching system generates bandwidth metrics for a destination site. The traffic control processing logic receives these metrics and includes a utilization module that determines utilization based on the received metrics. An error calculation module computes the difference between the determined utilization and a target utilization. Additionally, a gain and filtering module computes a correction value based on this difference. The bandwidth control processor then assigns bandwidth allocation based on the control value derived from these calculations.

Another significant patent is the "Power Control System for Communications Channels." This system is designed to control and conserve signal transmission power in a communications system. It includes a first unit with a transmitter and receiver, and a second unit with similar components. The system determines the received signal power needs of the second unit receiver and generates a reverse channel explicit-power-request command. This command indicates the absolute power level at which the first unit transmitter should transmit signals. The system also generates a forward channel explicit-power-notification message based on the transmitted signal power from the first unit transmitter.
