Title: Alan L Bryenton: Innovator in Optical Technology
Introduction
Alan L Bryenton is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of optical technology, holding a total of 2 patents. His innovative work focuses on methods and apparatuses that enhance the functionality of banknote reading and optical sensing.
Latest Patents
One of Bryenton's latest patents is a Portable Hand-Held Banknote Reader. This invention provides a method and apparatus for reading banknotes by storing signals in memory. The imaging apparatus includes a stationary light source, mirror, charge coupled device (CCD), and lens. The method involves raster scanning the face of the banknote with the CCD to obtain a serial signal representing the printed pattern. The system then searches the memory for the serial signal, compares it with stored signals, and indicates the correct presence of the banknote if the comparison meets a predetermined degree.
Another significant patent is the Microbend Optic Sensor with Fiber Being Sewn Thereto in a Sinuously Loop. This optical sensor comprises an optical fiber with a core covered by cladding, which has a different index of refraction. The apparatus retains the fiber in a sinuously looped disposition and fixes it to an object to be sensed. Movement results in accordion expansion and contraction of the loops of the fiber, leading to microbending. The system applies a first optical signal into one end of the fiber and detects the resulting optical signal from the other end, allowing for the comparison of signals to indicate movement.
