Title: Innovations by Alfred Hans Unden

Introduction

Alfred Hans Unden is a notable inventor based in Owens Cross Roads, Alabama. He holds a total of 3 patents that showcase his contributions to the field of electromagnetic ranging and location technologies. His work is particularly significant in enhancing safety and efficiency in various applications.

Latest Patents

One of his latest patents is a "Method of near-field electromagnetic ranging and location." This innovative method utilizes the long-wavelength, near-field characteristics of low-frequency RF signals, particularly those in the AM broadcast band. These signals are resilient against scattering from small objects and are only slightly affected by urban landscapes. The method employs an RF fingerprinting approach that captures the behavior of gradually varying signal characteristics. It can utilize transmit tags that communicate with a network of locator-receivers or locator-receiver tags that detect signals from fixed transmitter beacons. Additionally, it can incorporate uncooperative signal sources, such as AM broadcast signals, to enhance its functionality.

Another significant patent is related to firefighter location and rescue equipment, known as FLARE. This system consists of multiple tag transmitters and locator-receivers that work together to determine the location of firefighters in emergency situations. The system compiles signal characteristic data in a reference database and compares it to evaluate the location of tag transmitters relative to the paths taken by others. This innovation aims to improve the safety and efficiency of rescue operations.
