Title: Innovations by Charles B Stieff

Introduction

Charles B Stieff is an accomplished inventor based in Kensington, MD (US). He holds 2 patents that showcase his innovative contributions to technology. His work primarily focuses on advancements in monitoring systems using fiber optics.

Latest Patents

Stieff's latest patents include the development of electronic fiber optic seal monitors. This innovative seal monitor utilizes a time-dependent pseudo-random number or a number from a time pad, which are lists of random numbers often used in encryption. The number changes periodically, for example, once an hour or at a time interval deemed appropriate for the specific application. A remote monitoring station sends a request to the monitor, which responds with a random number based on the time the monitor was started and how much time has elapsed. If the random number returned is correct, it indicates that the monitor is functioning properly and the seal has not been tampered with. Conversely, if the monitor does not respond or provides an incorrect number, it suggests that either the monitor or the seal has been compromised. Additionally, light transmitted through a cable is periodically compared with historical outputs from that cable.

Another significant patent is the self-monitoring seal. This invention features ends of fiber optic bundle loops mounted in tamper-resistant containers. A battery powers microelectronics that change a display in a predetermined sequence. Tampering with the container or altering the light transmission through the fiber optic bundle disrupts the predetermined display sequence, thereby indicating potential tampering.
