Abstract: Methods and systems are presented for improving operation of an evaporative emissions system. In one example, the methods and systems estimate a fuel vapor concentration based on output of a fuel tank level sensor and output of a fuel pressure sensor. A canister purge valve is adjusted to an initial position at a beginning of a fuel vapor purging cycle to reduce a fuel vapor purging time.

Abstract: The present invention is directed generally to bed coverings for a mattress and, more particularly, to a fitted (or semi-fitted) top sheet that may be attached at one end to the mattress and which may be placed between a user and other bedding such as blankets, quilts, comforters, or the like. The fitted sheet provides for ease in changing or making the bed.
