Covid-era Gadgets @SF

San Francisco Explorer Rich shows and tells the group about a gadget intended to keep hands off of touchable surfaces to prevent cross-infections. His device is a Hygiene Hand Tool - shaped like a large key and made of brass, it can be used to open doors, push buttons, at the ATM, the gas pump and anything else one should avoid touching with a bare hand. His presentation spurs discussion, including some questions about the purported anti-microbial properties of the alloy. Before the meeting is over, Rich does  some research and answers the question.

Explorer Susan shares her use of a pulse oximeter - a fingertip instrument designed to display blood oxygen levels as well as pulse rate. The members note that this reading can be very important during the Covid outbreak as well as with respiratory infections, as a number of people have suffered from 'hidden hypoxia syndrome' - having very low blood oxygen levels with no accompanying symptoms. 

The group was in agreement that both gadgets could be useful beyond the period that avoiding Covid is a concern.
