Multiplexing: Reduce Cost and Complexity

Posted in Automated Test Stand Design, Automotive, Battery Pack and BMS Test Systems, Circuit Design, Custom Software and Hardware Development, Energy and Utilities, Green Technology, LabVIEW Programming, Telecommunications, Test and Measurement, Test and Measurement Automation

Multiplexing (Muxing) is an operation that selects one of many electrical signals and forwards the input into a single line. Demultiplexing (Demuxing) does the same operation, but in reverse, taking one electrical signal and outputting it onto one of many different wires depending on a selection. Muxing is an effective and relatively inexpensive wiring strategy that could reduce your circuit complexity and save you money. DMC has helped to implement muxing schemes on multiple projects and has witnessed...

Engine Fuel Injector Characterization with LabVIEW

Posted in Automotive, Energy and Utilities, Green Technology, LabVIEW Programming, Manufacturing Automation and Intelligence, Test and Measurement, Test and Measurement Automation

DMC was approached by an engine design and development company to create a method of characterizing fuel injectors for research and product development. A critical part of fuel injector performance is accurate timing of the control signals for opening and closing the fuel delivery valve. In this case, injectors are characterized for optimal control timing. Characterization for research and development is performed on a lab benchtop, and this technique would be ultimately required in full production....
