I disagree. - Supersonic and ultrasonic are adjectives which mean specific things, they're not jargon. - USM, pertaining to the use of ultrasonic ring motors of a specific type used as focusing servos in 35mm cameras, is a Canon trademark/ branding jargon. The use of the adjective "ultrasonic" in the above sentence means "frequencies above the pitch of human hearing". "Ultrasonic ring motor" is a descriptive term indicating a ring-shaped motor whose motive force is supplied by vibrating elements, those elements vibrating at frequencies above the pitch of human hearing.
