Anti-streptolysin O (ASO) is an antibody often found in the blood of people who have suffered a streptococcus infection. A blood test, known as the anti-streptolysin O titre, is sometimes used to test for the presence of this antibody in the blood. This test is considered useful because certain health conditions, such as rheumatic fever, usually only occur in people who have recently suffered or are suffering a streptococcus infection.
On December 26, 1933, he was awarded four patents for FM radio (The other two were applied for in 1927 and 1930, but weren't for wide-band).

Ford-O-Matic was the first automatic transmission widely used by Ford Motor Company. It was designed by Borg Warner Corporation and introduced in 1951 model year cars. The three-speed Ford-O-Matic evolved into the MX and FX or Cruise-O-Matic transmissions in 1958 and the FMX in 1968. This line continued in production until 1980, when the AOD was introduced.
