A server may be used to handle at least some of processing of content that is based on web access operations initiated in a set-top box, wherein one or more links between the server and the STB that are used to forward multimedia broadcasts are configured to free bandwidth for communicating at least a portion of the processed content to the STB. The invention further relates to a device for the production of said components and a system in which groups of said components are produced. The cutting surface and collector surface is relatively smooth compared to the cutting edge. A mop is employed to apply floor finish to easily accessible areas in one instance, yet allows the mop to be used independently for application of floor finish to not so easily accessible areas. The information regarding the note that may be stored in a memory may be forwarded to a regulatory agency or an external entity for reporting or record-keeping. The accuracies of multiple predictive models are measured and the models are combined based on the measurements, resulting in a more accurate predictive model of individual-specific affinities for attributes of the objects andor services.
