Title: Mark A Priest: Innovator in Fishing Technology and Radioactive Material Injection Systems
Introduction
Mark A Priest is a notable inventor based in Duncan, OK (US). He holds a total of 6 patents that showcase his innovative contributions to technology, particularly in the fields of fishing and radioactive material injection systems. His work reflects a commitment to enhancing user experience and safety in these specialized areas.
Latest Patents
One of his latest inventions is the Fish Strike Sensor. This device is designed to mount on various surfaces and includes a cradle for supporting a fishing rod and reel. The fish strike sensor features a movable spring retainer that releasably retains a portion of the fishing line. When a fish strikes the bait, the retainer moves a certain distance with the fishing line, at which point the line is released. This movement actuates a switch that activates a buzzer and LED, alerting the angler to the strike.
Another significant patent is the Closed Feedback Injection System for Radioactive Materials. This system is designed for injecting radioactive material into a high-pressure well stimulation fluid line. It allows for controlled injection rates based on desired and actual values. A controller calculates the desired injection rate based on job characteristics and uses a PID algorithm to ensure the actual and desired rates are equal. The system can be controlled manually through a device affixed to the controller or via a separate manual control unit.
