Abstract: A crutch mountable toy assembly for personalizing or decorating a crutch includes a three-dimensional body shape formed by an outer casing with a top end and a bottom end. The three-dimensional body shape defines a torso. A fastener capable of repeatedly opening and closing is attached to the torso. A resiliently compressible material is enclosed within the outer casing, defining a filling that expands the outer casing outwardly into the three-dimensional body shape. The three-dimensional body shape also has a channel therein extending into the top end and outwardly through the bottom end. The channel can encircle the crutch within the three-dimensional body shape. The outer casing also has a slit therein extending into the channel and outwardly through the outer casing. The channel is accessible through the slit. The fastener may be positioned adjacent to the slit, capable of overlaying and extending across the slit when the fastener is closed.

Abstract: A method and a system for indicating more than three different fluid levels in a fluid reservoir is described for a system that includes a fluid level sensor having only two output levels. In one example, the more than three different fluid levels are determined via output of the fluid level sensor and output of one or more sensors that indicate acceleration or orientation of a vehicle.

Abstract: Systems and methods for operating an engine with an oil pump that supplies engine oil to various oil consumers in an engine are presented. In one example, a displacement of a variable displacement engine oil pump is adjusted to provide sufficient oil pressure throughout the engine, but low enough to conserve fuel.

Abstract: Methods and systems are provided for filtering an oil dilution amount based on a current value of the oil dilution amount. In one example, filtering the oil dilution amount may include decreasing a sensitivity of filtering at lower oil dilution below a threshold; otherwise, increasing the sensitivity of filtering. The sensitivity of the filtering may be decreased by implementing a larger time constant, while the sensitivity of the filtering may be increased by implementing a smaller time constant.

Abstract: Stereolithography is used to fabricate directly a single-piece, missile-usable, accurate, flightweight igniter without the use of intermediate, non-operational molds or prototypes in the fabrication process. The same prototype-less, direct stereolithography can be used to produce other missile-usable parts by designing each such part to be of a single-piece configuration and by using material that is suitable for both stereolithography and functional missile application.
