Abstract: A computer system comprises a receiver and a read-write medium. The receiver is used to receive a remote control signal from a remote controller. The read-write medium is applied to the computer system, and an operating software is stored therein. The computer system can analyze the remote control signal via executing the operating software. The computer system can select and execute some application programs in the computer system or change hardware settings according to the remote control signal.

Abstract: A remote control model car includes a rear suspension mechanism mounted in either side of the chassis. The chassis has a suspension body. The rear suspension mechanism includes a pivotal adjustment rod coupled to the lug of the suspension body, a pivotal arm mechanism, a hub mechanism, and a shock absorber pivotably secured to the arm mechanism and the suspension body. This arrangement allows for a smooth, simple, and reliable wheel angle adjustment.
