Title: Innovations by David R Hamilton: Pioneering Utility Data Communications
Introduction
David R Hamilton, an accomplished inventor based in Auburn, AL, has made significant contributions to the field of utility data communications. With a total of three patents to his name, Hamilton has focused on enhancing the efficiency and functionality of utility meter reading systems. His innovative work is vital for modernizing how utility companies manage meter data.
Latest Patents
Among his notable innovations is the patent for a reader/programmer designed for two and three wire utility data communications. This system allows for the remote reading of utility meter registers, vastly improving the convenience and accuracy of meter readings. In the two-wire variation, the hand-held reading unit utilizes inductive coupling over two wires from a remote port to the meter register. Alternatively, a Meter Interface Unit (MIU) can be directly connected via three wires.
Each utility register in Hamilton's design comprises multiple wheel position encoders. The reading unit sends an AC interrogation signal to the meter’s encoder circuitry, powering it and enabling the reading of each encoder wheel's position. In the two-wire mode, the display information (e.g., current meter reading) is transmitted back by altering the load presented by the register side of the circuit, resulting in a corresponding variation in current drawn from the reading unit. The current-modulated signal is decoded to yield the meter reading.
Hamilton's system is also capable of operating in a three-wire mode, facilitating the reading of older fourteen wire encoded registers. Additional features include remote programmability of register characteristics, real-time flow rate and leak detection, and the ability to read compound meters—those with two registers to measure high and low flow rates separately.
