Abstract: An improved cleaning head for a vacuum assembly. The cleaning head has a body with a bottom surface. Within the cleaning head is at least one suction channel that leads into a vacuum cleaner. A first rotating brush is mounted to the body of the cleaning head in front of a suction channel. A towelette support is mounted within the body adjacent the first rotating brush. The towelette support is configured to receive a disposable towelette. A second rotating brush may also be provided, wherein the towelette support would be interposed between the first and second rotating brushes. A mechanism is provided for selectively moving the towelette support within the body between an extended position and a retracted position.

Abstract: A system and software for scheduling courses at an institution that offers a variety of courses in different semesters. Scheduling software is provided that is accessible to a student through a computer network. The scheduling software filters courses being offered by eliminating courses that have been previously completed by the student. Courses that do not serve as one of the student's course requirements are also filtered. Likewise, courses that have prerequisites yet unattained by the student are filtered. After the initial filtering process, the student is presented with filtered course offerings. The student selects courses from the filtered course offerings, therein creating scheduled courses. The scheduling software automatically updates the filtered course offerings after each selection of a course to eliminate any of the offered courses that conflict in date and time with scheduled courses.

Abstract: The invention relates to computer based methods and systems for planning, managing and scheduling of the participation of users, be they individual or groups, in an exponential smoothing manner with respect to activities at, e.g., a mega amusement park (“MAP”) or other venue.
