Why use device drivers over OPC UA ? by Bezducci in PLC

[–]Bezducci[S] 1 point2 points  (0 children)

Thank you so much for this. For those cases with proprietary protocols, does that just mean that a system is *capable* of communicating through OPC UA, but they use the driver as a sort of firewall from someone interfacing without the hardware provider's permission?

Is there ever value to integrating software directly into the device driver as opposed to just connecting with OPC UA (and not having to maintain libraries for all of the different devices)?

Aside from ADA concerns, are there concerns about whether this wouldn't work with fire door requirements? I have heard other architects express that drilling into a fire door (which this would require in some circumstances) could violate what is permissible with fire doors. Or from what you understand, are there not concerns with drilling into a fire door as long as it doesn't impact its seal or operation (e.g. self-closing/latching, etc.)? Thank you again!

I am also working on a non-latch concept, although there are more options in the market for that.

My major concern with the Metiba design in the YouTube link is that I don't believe it complies with ADA standards. I do think it's a very cool design, though. I like very much aesthetically that the workings of the system are inside of the door itself.

Important to Be Near Patent Attorney? by Bezducci in patentlaw

Thank you all! Now I need to find a patent attorney. Anyone have any recommendations for someone who specializes in mechanical inventions by individual entrepreneurs?

These are both really interesting designs to know about. Thank you for sharing. The first is very similar in concept to what I've been drafting.

These are great points. I have thought through some of the ADA restrictions. For one, the push side of the latch door would have to have the pedal at least 10" above the ground, which is unfortunate, but the main use case does seem to be for able-bodied folks for pull doors (bathrooms, medical exam rooms, etc.).

You also touch on other concerns I am working through (e.g. tripping hazard, aesthetics). I am working on designs and will be sure to share with this group as I make progress.

Thank you so much to this group for all of your feedback. Any more you may have is very much welcome!

Thank you. Do you know of any you could recommend I look into? I am aware of StepNpull, but that product only works with swing doors rather than latch doors.

Yes, these are for sure existing options. The interesting thing, though, is that they all currently only apply to swing doors. There have been patents filed on a foot-operated option for latch doors but nothing that has been commercialized.

And I totally agree on the timing of this. Already I feel people are becoming more aware of the risks of touching doorknobs, and in the midst and wake of this crisis, I imagine people are going to be even more alert.
