Air suspension is a type of vehicle suspension powered by an engine-driven or electric air pump or compressor. This pump pressurizes the air, using compressed air as a spring. Air suspension replaces conventional steel springs. If the engine is left off for an extended period, the car will settle to the ground. The purpose of air suspension is to provide… Read More »
Intelligent Transportation Systems (ITS) is the application of computers, communications and sensor technology to improve the efficiency or safety of surface transportation systems.ITS aims to transform surface transportation into an effectively managed, well integrated, universally available, customer-oriented and affordable system that ensures quick and safe movement of people and goods.
An ultrasonic motor is a type of electric motor formed from the ultrasonic vibration of a component, the stator, placed against another, the rotor or slider depending on the scheme of operation (rotation or linear translation). Piezoelectric ultrasonic motors are a new type of actuator. They are characterized by high torque at low rotational speed, simple mechanical design and good controllability. They also provide a high holding torque even if no power is applied.
