Osi Systems, Inc.
Could not find a ticker for this position, may be a filing error
A vertically integrated maker of specialized electronic systems for security, healthcare, and defense, OSI Systems runs three divisions: Rapiscan and S2 screening gear used at airports and borders, Spacelabs Healthcare patient monitors, and optoelectronic components for original equipment manufacturers. Founded in 1987 as Opto Sensors, Inc., the company's "OSI" name comes from those original initials. A fun quirk: its Rapiscan brand is a portmanteau of "rapid" and "scanner."
