Latest Patents

One of Schieble's key inventions is the 3-Wire Multiplexer. This invention provides a 3-wire multiplexing system that exhibits high noise immunity, making it particularly suitable for industrial control applications. The system features a master station that supplies AC power, along with clocking and synchronization information, to multiple remote transmitter and receiver stations. A 3-wire cable connects the master station to the remote stations, where two wires serve as power lines, L1 and L2, isolated from each station by respective transformers. The third wire acts as a data line, which is optically coupled to the remote stations. This design allows the remote stations to be completely isolated from the cable while still being powered, clocked, and synchronized without the need for local power supplies or clocks. The signaling method employed switches the data line onto the power lines, ensuring a high degree of data security by recognizing both the polarity and the position of a pulse on the data line within an AC cycle. Additionally, the system provides diagnostics in remote receivers, including half-cycle polarity and position decoding, error detection, and fail state selection.
