Hello
I am working on using sound as a condition monitoring tool. I currently have a system setup where a microphone monitors a set of metal shears. Input is via the PC soundcard. I have a VI setup that listens for the cutting action. It then extracts a portion of the signal, in this portion it should be possible to detect a second sound which is the cut (cropped) metal falling into the bin.
I have the system working such that there are two indicators on screen. One indicator denotes a crop detected and the second indicates that it has been succesful. What I want to do is combine this into a single indicator - i.e. if crop=true and succes=true then indicator =green, and, if crop=true and success=false then indicator=red.
The problem I have is that the two events occur at different times so I need to 'latch' the first crop signal for a period of time while listening for the second event. However I can't seem to create a latch that works.
Any help greatfuly received.
Thanks
