Abstract: A remote-controlled electric golf bag cart has a remote control, a support frame, an antenna set and a control module. The remote control transmits a distance measurement signal. The support frame has a wheel assembly, a golf bag stand and a motor assembly mounted thereon. The antenna set and the control module are mounted on the support frame. The antenna set receives the distance measurement signal. The control module determines an orientation and a distance of the remote control according to the distance measurement signal received by the antenna set, and drives the motor assembly to move the support frame forward toward the remote control, making the support follow a user having the remote control and preventing other in-field persons and obstacles from affecting the support frame to follow the remote control.

Abstract: Golf cart movements at a golf course are controlled by a limited access controller that compares a golf cart's GPS-determined position against a limited access map to restrict performance of inputs by the golf cart's driver to the golf cart's motor under predetermined conditions, such as if a golf cart enters or has a predetermined likelihood of entering a limited access area. The limited access controller inhibits motor responses, such as by preventing motor operation, limiting available motor speeds, or allowing motor operation only in a vector that removes the golf cart from the limited access area, such as operation in reverse. Golf carts of a golf course communicate with a base station that updates the limited access map by defining limited access area perimeters and allowable actions within a limited access area and that directly commands allowable motor operations. For example, golf carts are prohibited from entering green areas, are restricted to golf cart paths during cart-path-only periods, and are restricted to reduced speeds in driving hazard areas.

Abstract: A golf cart or caddy and a mobile transmitting device carried by a golf player are each provided with a receiving and evaluating device equipped with a computer for a satellite-controlled positioning system. The two receiving and evaluating devices calculate the respective positions of the golf player and the golf caddy from the signals cyclically received from the satellite system. The mobile transmitting device is provided with a high-frequency manual transmitter which transmits, also cyclically, the positions of the golf player to the golf caddy. The computer of the golf caddy calculates direction and distance of the golf player and stores the data up to the time when the caddy follows the stored path upon a signal. The golf caddy stops at a predetermined distance from the golf player. When a stationary reference transmitter is additionally used for correcting the position data of the golf player and the golf caddy received from the satellite system, specific areas of the golf course can be excluded as forbidden areas, so that these will not be traveled by the golf caddy.

Abstract: The ultrasonic tracking control effects that a pacemaker going ahead is automatically tracked by an automotive vehicle at a predetermined distance. To this end, a control unit (13) of the vehicle (10) is equipped with two ultrasonic units (F1,F2) comprising a transceiver device for ultrasonic signals each. The pacemaker going ahead carries a second control unit (14) with a transponder (S) responding to the signals of the ultrasonic units (F1,F2). Upon reception of an ultrasonic signal, the transponder (S) outputs a response signal which is received by the respective ultrasonic unit. The distance of the vehicle from the pacemaker and the tracking angle (.alpha.) are determined in the first control unit (13) from the signals received by the ultrasonic units (F1,F2), and traveling and steering signals are generated such that the vehicle tracks the pacemaker at a predetermined distance.
