Title: The Innovative Mind of Allen C. Hagelberg
Introduction
Allen C. Hagelberg is a notable inventor based in Diamond Bar, California, with a remarkable portfolio of eight patents. His work primarily focuses on advanced communication systems and technologies that enhance security and efficiency in various applications.
Latest Patents
One of his latest patents is the Missile Shield, which is a covert and secure communication system. This system employs a very narrow bandwidth to allow receivers to be highly sensitive to low power signals while maintaining acceptable signal-to-noise ratios. The preferred embodiment operates at millimeter wavelengths, which are undetectable beyond a limited range due to high atmospheric attenuation. In another embodiment, the covert communication system is integrated into an Identification Friend or Foe (IFF) system used in conjunction with homing missiles. This innovative IFF system serves as a backup to confirm that a target is an enemy by transmitting and receiving a confirming signal when the target and missile are less than 2,000 feet apart. The system's design minimizes detectability and enhances security by limiting transmission to the final stages of missile engagement.
Another significant invention is the Electronic License Plate Apparatus and Method. This apparatus conveys information from an object through the delayed reflection of an interrogating ultra-high range resolution radar signal. The signal is digitized into a series of programmable spaced pulses by an electronic license plate circuit. The electronic license plate consists of multiple unique programmable delay lines connected through a coupler network to an antenna.
