  • Patent number: 6538258
    Abstract: A microprocessor-controlled mobile machine for curing a floor coating includes a source of radiant energy in the form of ultraviolet (UV) light which is mounted to the machine. The machine may be operated in a Traverse mode under operator control of speed for moving to an application site. A Standby mode permits the UV applicator to operate at a quiescent state to reduce warm-up time while permitting the machine to be maneuvered by the operator. A Cure mode (of which there may be a plurality) operates the machine at predetermined, processor-controlled speed and the UV applicator at a predetermined power level.

  • Publication number: 20020115052
    Abstract: An on-line educational system. An instructor builds a course on-line containing identification of assignments and educational materials, which are compiled into an on-line electronic syllabus. Users enrolled in the course may access the electronic syllabus and perform various functions with the on-line educational system in order to participate in the on-line educational course. An editor tool permits instructors or others to dynamically change, modify, and edit educational courses for the on-line educational courses. An interface facilitates the creation and editing of content between a user and the database for the on-line educational system.

  • Patent number: 6163915
    Abstract: A floor care machine such as a burnisher may operate in a manual or automatic mode for controlling the operating pressure of the working unit, such as a brush or pad. The illustrated machine has a motor and pad driver assembly mounted for height adjustment by an actuator. In the automatic mode, a transducer senses motor current (i.e., load) and generates a signal representative of the actual operating pressure exerted by the pad on the floor. A microprocessor-based controller controls the actuator to adjust the height of the pad relative to the floor, and thus adjusts the pad pressure on the floor, according to a setting selected by the operator. The controller is programmed to reduce the effect of "hunting" by entering a Lock Mode after operation has achieved predetermined conditions. System operation remains in the Lock Mode as long as other criteria are met, and operation returns to a Hunt Mode if these other criteria are not met.
