Digital anti-lock speed sensor

摘要

An anti-lock braking system includes a speed sensor and a central processing unit ("CPU"). The speed sensor includes a motion sensor, an integral processing unit ("IPU"), and a housing which surrounds the motion sensor and the IPU. The motion sensor produces an analog signal as a function of a movement of an object, and the IPU converts the analog signal to a digital signal within the speed sensor. The IPU of the speed sensor transmits the digital signal to the CPU as a function of the analog signal received from the motion sensor. The CPU achieves an anti-lock braking action of the object as a function of the digital signal received from the IPU of the speed sensor.
