Questions regarding computer usage during the Product Demonstration

Post by Julie F » Fri Jan 15, 2021 11:56 am

In the Ranger class manual, it states that “Companies may take a screenshot of the coral colony and transfer it to another screen/device at the product demonstration station to have that device implement the image recognition.” If the camera is connected via USB to a computer (but powered through the MATE power supply) and the computer itself has company created software to complete the task, can the computer be used instead of transferring it elsewhere as the manual suggests? This question also applies for the photomosaic task.


Additionally, could said computer serve as a monitor throughout the Product Demonstration? This is more efficient than switching between a MATE powered monitor and the computer when screenshotting for the coral colony task and the photomosaic task.

Yes. You could have a computer serve as a monitor during the product demonstration run and also have that computer run your image processing software to complete (and display) your coral colony / photomosaic results.

Good luck.

To clarify, said electronic device (computer, tablet, cell phone, etc.) may be ran through an independent power source as opposed to the MATE power supply correct?

Monitors, computers, cell phones, etc. do not need to run through / be powered by the MATE power supply. They may be powered by their own batteries or plugged in to topside AC.

Only the signals / power that travels through the tether must be powered by the MATE power supply. So the camera taking your underwater images must powered by the MATE supply. But once you get that image topside, whatever device is displaying it, utilizing the image can be powered by surface AC, or may have battery power (for cell phones / tablets / laptops).

Good luck.
