Automated Vision Inspection of Chemical Droplets

Posted in LabVIEW Programming, LabVIEW Vision Application Development, Pharmaceutical & Medical, Test and Measurement, Test and Measurement Automation

DMC developed a machine vision inspection system to measure the size and position of chemical reagent droplets on a medical device. The customer added fluorescein to the chemical reagent so that the drop would fluoresce under certain lighting conditions. DMC’s software compared the drops’ sizes and positions to acceptable criteria and generated a pass/fail result. Data and images for each inspection was logged for later traceability.

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...
