A method/apparatus/system for generating a recommendation based on user interactions with nodes and associated tasks within a prerequisite graph. The recommendation is generated by identifying the user's current position within the prerequisite graph and identifying potential next nodes to which the user could move. Based on the user's past interactions with nodes and/or tasks within the prerequisite graph, the user's likelihood of successfully completing the potential next node is calculated, and a recommendation is made based on this calculated likelihood of the user successfully completing the potential next node.

Network-probability recommendation system

Methods for customizing an educational experience of a gamer are provided. The method can include the generating of learning DNA which can include information relating to the gamer. The learning DNA can be generated by the aggregation of data received from the gamer, collected from other data sources, and generated based on the interaction of the user with an evaluation and rectification system. The method can further include selecting a mission for a user based on the learning DNA and/or information relating to the user.

Evaluation and rectification system

Disclosed herein is a brush for cleaning carpets which includes a base member by which the brush is secured to the underside of a rotary or oscillating machine to impart a corresponding movement to the brush; a plurality of bundles of bristles, each bundle extending from the underside of the base member and being spaced from adjacent bundles; and a plurality of freely rotatable spheres journaled in the underside of the base member and protruding therefrom to support the weight of the brush and machine and vibrate against the carpet as the brush is driven thereover.

Carpet cleaning brush

A method and apparatus for cleaning carpet. The pile of the carpet is first lifted, opened and agitated by stiff rotating brushes and beater bars, separating the foreign matter therein from the pile and bringing the matter to the surface of the carpet. The carpet is then vacuumed removing the separated matter therefrom. A film of cleaning agent is then sprayed through a hand-held wand over the carpet encapsulating the carpet fibers. The wand communicates with a portable pressurized supply of cleaning agent. After a short setting, the carpet is scrubbed with counter-rotating or rotary brushes. The agent is then allowed to dry and the residue removed with a vacuum.
