Louis Ross, President & CEO of Virtus Advanced Sensors, discusses his company's inertial sensors and accelerometers as well as their applications, including a version of the Sony PlayStation Portable handheld game console that replaces the analog 'nub' with a 3-axis accelerometer for tilt and motion control. Virtus Advanced Sensors is a fabless sensor company commercializing inertial sensor technology developed using MEMS (Micro Electro-Mechanical Systems) and micro-machining methods. The company maintains a patent portfolio of over 80 registered US and European patents MEMS inertial sensor technology, which includes multi-axis accelerometers and gyros and integrated motion sensors. Virtus' true "single-chip" solution to producing multi-axis MEMS inertial sensors is an industry first, and will lead to the production of the world's first single chip 6-axis MEMS motion sensor.
