Latest Patents

D Duncan Earl's patent, titled "Method and apparatus for active tamper indicating device using optical," introduces an innovative solution to detect tampering in systems requiring robust closure security. The device utilizes an optical time-domain reflectometer (OTDR) to launch pulses of light into a system of multiplexed links, capturing waveforms of the pulses reflected by seals in those links. When a seal is compromised, the transmission of light pulses becomes discontinuous, allowing the OTDR to promptly detect which seal has been opened. This invention serves as an essential system of active seals, designed for various applications that demand immediate tamper detection and accommodate periodic access to secured closures, whether indoors or outdoors, and over long distances.
