Title: The Innovations of William A. Friday
Introduction
William A. Friday is a notable inventor based in Huntsville, Alabama, recognized for his contributions to optical systems and synchronization technology. With a total of 2 patents, his work has significantly impacted the fields of photonics and device control.
Latest Patents
One of his latest patents is the "All-optical pulse generating and amplifying system." This innovative system utilizes a phosphor that is excited by input light of a first wavelength, which then emits light of a second wavelength. The emitted light illuminates a bistable element that switches from a non-transmissive state to a transmissive state at a pre-fixed intensity, allowing light pulses to exit the system. Additionally, an inhibitory light quenches the phosphor light emission, returning the bistable element to its non-transmissive state, thus restarting the process. This system can also function as an amplifier by gating the intensity of the light output in proportion to the input light intensity.
Another significant patent is the "Synchronizer circuit for synchronizing the scan of a device." This synchronization circuit responds to externally supplied trigger input signals, providing a time-adjustable output trigger pulse to a laser or similar device. It processes a square wave frequency signal input and drives a multivibrator network controlled by a delay selector circuit. This allows for precise adjustments of the output time delay, enabling accurate control of the device's operation.
