  • Publication number: 20090038864
    Abstract: The invention relates to a cart for carrying one or more a golf bags and/or other things, which cart is moveable on wheels and operable in response to transmission of one or more command signals generated in response to activation of at least one operator input device, preferably mounted on or in a remote control, and a method for steering a cart. In one aspect, the cart includes a front-located drive wheel assembly with a drive motor for moving the cart forward by driving at least one drive wheel, and at least one rear-located steerable wheel assembly for turning the cart while it is moving forward. The steerable wheel assembly comprises a steering motor, a center-lock device, and a cart steering wheel. The steering motor and center-lock device may be electrically coupled to one another for coordinating their respective activations in response to one or more of the command signals for holding the steering wheel against pivoting, releasing the hold, and pivoting the cart steering wheel.

  • Publication number: 20080000036
    Abstract: The invention relates to an apparatus and a method for automatically cleaning and drying balls, including golf balls. The apparatus comprises a housing that contains a cleaning liquid, scrubbing channel, drying section, and rotator. An electric motor, which rotates the rotator, is switched “on” in response to a sensor detecting a ball in an entry chute. The rotator moves a ball carrying means (preferably including a wheel for spinning the ball) for receiving the ball from the entry chute and moving the ball through the scrubbing channel and drying section to a point for the ball to exit. The motor is switched “off” in response to a sensor (which can comprise a cam and limit switch) detecting, directly or indirectly, that the rotator has rotated at least enough for the ball to exit. Alternative embodiments may comprise ball counting means and/or biasing means.
