  • Patent number: 5719555
    Abstract: A golf cart control and monitoring system, includes a signal transmitter, at least one antenna, a receiving and processing apparatus, and an event log device. The signal transmitter transmits a plurality of electromagnetic digitally modulated signals. The receiving and processing apparatus receives the electromagnetic signals radiating from each antenna and processes the signals to determine the position of the cart with respect to each antenna and correspondingly with respect to the prespecified feature. A control signal is outputted therefrom representative of the location of the cart. The event log device is responsive to the control signals and generates historical log of how long and how many times the golf cart is located within course restricted areas. In another embodiment, digital signals are radiated from antennas proximate designated start areas, designated stop areas and designated intermediate cart travel positions to track time of play and to provide displays of same to a cart operator.

  • Patent number: 5610586
    Abstract: A golf cart control and monitoring apparatus, includes a signal transmitter, at least one antenna, a signal receiving and processing device, and an event log device. The signal transmitter transmits a plurality of electromagnetic signals, each signal being representative of a position with respect to a restricted area of a golf course. The signal receiving and processing device receives the electromagnetic signals radiating from the antenna and provides output signals representative of the location of the cart with respect to the restricted area, where at least one of these output signals is representative of the golf cart being located in the restricted area. The event log device is responsive to the signal receiving and processing device and generates historical log of how long and how many times the golf cart was located within golf course restricted areas.

  • Patent number: 5438319
    Abstract: A golf cart control and monitoring apparatus, includes two antennas spaced from each other, two transmitters, two receivers, two alarms, an event counter, a time accumulator and a display for the events counted and the time accumulated. The two antennas are each disposed about a golf course restricted area and one antenna is disposed outside of the other. One transmitter transmits a first electromagnetic signal from one antenna which signal is received by the first receiver. The second transmitter transmits a second electromagnetic signal from the other antenna, which signal is received by the second receiver. The first alarm generates an alarm indicating that a golf cart is approaching a restricted area of a golf course in response to the first output from the first receiver. The second alarm generates another alarm, distinct from the first alarm, and an external alarm indicating that a golf cart has entered the restricted area in response to the second output from the second receiver.
