The present invention relates to an apparatus, a method, and a sensor for scanning engine oil of a vehicle. The communication system uses baseband codes formed from time shifted and inverted wavelets to encode data on a RF signal. If, however, the buyer’s upper limit is below the seller’s lower limit, the model provides a \u201cno match\u201d indication or alternatively suggests a theoretical price point between the respective limits. The subject invention further provides a pharmaceutical combination comprising separate dosage forms of an amount of glatiramer acetate and an amount of mitoxantrone, which combination is useful to alleviate a symptom of a form of multiple sclerosis in a subject. The switch from AC power to battery power, or vice versa, can be made on-the-fly, in realtime, without disrupting the underlying software application that is being run on the computing device. Such manufactured item may have the shape of small bricks, bricks, blocks, small blocks, curbs, interlocking paving blocks, panels, tiles, prefabricated slabs, beams, elements for walls, modular building elements, indoor and outdoor cladding elements, blocks, rocks, supports.
