Masimo Corporation is a $250 million Irvine, California-base manufacturer of noninvasive patient monitoring technologies that sells its products, both direct and through a network of OEM partners, to hospitals and health care professionals around the world. The company was founded in 1989 by a young electrical engineer named Joe E. Kiani, who was soon joined by his friend and fellow engineer Mohamed Diab. Together, the two initially operated the company out of Kiani's condo in Mission Viejo, California. Masimo today is best known for the invention of Measure-Through Motion and Low Perfusion pulse oximetry, which the company markets as Masimo SET (for Signal Extraction Technology). Kiani, 43, is currently Chairman and CEO of the global corporation.
