Interesting patent
The group's mascot, cuhulin, posted a link to a very interesting
patent. It purports to be a super quiet switchmode power supply. http://patft.uspto.gov/netacgi/nph-Parser? Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2 FPTO %2Fsrchnum.htm&r=1&f=G&l=50&s1=7,196,892.PN.&OS=PN/7,196,892&RS=PN/ 7,196,892 It is a different twist to the standard noise source. Terry |
