Vs say USA where 80% are not even connected and where some are connected but the door doesn&amp;#x27;t respond for 1-2 seconds?&lt;p&gt;95% there are no light sensors, only pressure sensors. I&amp;#x27;m guessing in the USA those are mandatory that there is a light sensor that if interrupted, causes the doors to open. In Japan those mostly don&amp;#x27;t exist, there is only a pressure sensor&lt;p&gt;In Japan it&amp;#x27;s not uncommon to have someone exit the elevator and just as they exit, press the close button so the door will close immediately behind them. This is a &amp;quot;sorry I interrupted your time by having to stop the elevator&amp;quot; gesture. This wouldn&amp;#x27;t work in the USA because the light sensors would trigger the doors reopening.</text><parent_chain></parent_chain></comment><story><title>Undo codes for Japanese elevator floor buttons</title><url>https://soranews24.com/2017/08/18/the-secret-undo-codes-for-japanese-elevator-floor-buttons/</url></story>

Anyone else remember that type of control? It&amp;#x27;s probably from the 40s&amp;#x2F;50s. I haven&amp;#x27;t seen one since.</text><parent_chain></parent_chain></comment><story><title>Undo codes for Japanese elevator floor buttons</title><url>https://soranews24.com/2017/08/18/the-secret-undo-codes-for-japanese-elevator-floor-buttons/</url></story>
