Abstract: A road condition monitoring system for a vehicle is provided. The vehicle is supported by at least one tire and includes a central communication system. The system includes a processor in electronic communication with the central communication system. An identifier is in electronic communication with the processor, receives vehicle condition data from the central communication system, and identifies a free rolling instance of the at least one tire. A slip estimator is in electronic communication with the processor, receives speed data from the central communication system, and determines slip characteristics of the at least one tire during the free rolling instance. A classifier is in electronic communication with the processor, receives the slip characteristics of the at least one tire, and identifies a road surface condition from the slip characteristics.

Abstract: A multi-component housing having a length and comprising at least a first component comprising a first plastic material, a second component comprising a second plastic material, and a third component comprising a third plastic material. The housing includes at least one tolerance-elimination element made of the second plastic material and longitudinally attached to the first component along the housing's longitudinal axis. The tolerance-elimination element has an average length extending parallel to the housing's longitudinal axis, which average length is at least ten times less than the length of the housing. The third component at least partially forms an outer surface of the housing, so that the tolerance-elimination element is at least partially overmolded by the third plastic material.

Abstract: A plurality of mass-produced identical multi-component housings for toothbrush handles, each housing having a length of about 120-200 mm, which is at least three times greater than a maximal orthogonal dimension thereof. Each housings includes at least a first component made of a first hard-plastic material, a second component made of a second hard-plastic material, and a third component made of a soft-plastic material, which are integrally joined together to form a generally tubular structure. Each housing includes a tolerance-elimination element made of the second plastic material, attached to one of first component's ends, at least partially overmolded by the soft-plastic material, and having an average length of about 3-20 mm, which average length varies among at least some of the tolerance-elimination elements by a lengthwise dimension that is at least ten times greater than the lengthwise maximal dimension variations of the length among the individual multi-component housings.
