Title: Duane S Edgar: Innovator in Programmable Controller Technology
Introduction
Duane S Edgar is a notable inventor based in Schaumburg, IL (US), recognized for his contributions to programmable controller technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest patents is the "Resolver analog to digital input module for use in a programmable controller." This module is designed to provide position data from an externally located resolver connected to a machine's shaft to the programmable controller's processor module. The innovation involves moving the resolver analog-to-digital conversion circuitry from an external module location to the programmable controller input/output rack. This design allows for synchronization with the programmable controller's input fetch signals. Additionally, it features a user-operable entry mechanism for digitally offsetting the resolver position by a user-selectable amount, accommodating different scale factors. The module also includes synchronization and alignment circuitry to compensate for different resolver gear ratios in coarse-fine geared resolver decoding circuitry. Furthermore, it provides a numerical display of the digitally offset resolver position data and BCD coded output data for easy connection to remote digital displays.
Another significant patent is the "Interrupt zone in rung of ladder program in programmable controller." This method and device control outputs to multiple output devices relative to inputs and synchronize the updating of selected outputs with the occurrence of an external event. An interrupt signal is derived from an external event at one or more input devices and supplied to a micro-computer. The device includes a user ladder program for controlling the outputs, with one or more interrupt zones that are immediately responsive to the interrupt signal for instantaneously updating selected outputs.
