Abstract: A motor vehicle seat with an integrated child seat comprises inflatable chambers that can be brought from a compressed air source. The child seat includes air chambers that are inflatable in multiple, e.g., three, stages, and which are fixed, e.g., adhesively bonded or stitched, to the surface of the motor vehicle seat.

Abstract: Methods and systems are provided for the design and manufacture of a crankshaft of a piston internal combustion engine. In one example, a crankshaft comprises a crankshaft throw, the crankshaft throw comprising a crankpin and crank webs. The crank webs are formed asymmetrically in a region of the crankpin with respect to a plane intersecting an axis of rotation of the crankshaft and a center axis of the crankpin, such that the breaking strength of the crankshaft throw is increased at a crankshaft angle of rotation which differs from the top dead center position of a piston to which the crankpin is coupled, and at which the piston exerts a maximum combustion-induced force on the crankpin.

Abstract: A folding bicycle has a main-frame with a bottom bracket, crank, pedals, and a seat post. A front is attached to the main-frame by a front hinge having an axis parallel to the crank axis, and has a mono-fork suspension. The front frame rotates about the front hinge to a folded position wherein the mono-fork is behind the front hinge axis. A rear swingarm suspension has a rear sprocket and is attached to the main-frame by a rear hinge that preferably is coincident with the crank axis. The swingarm is of a single-stay configuration and is rotatable about the rear hinge to a folded position wherein the rear sprocket is forward of the crank axis. The main-frame may consist of left and right sidewalls spaced apart from one another, and the mono-fork lies at least partially between the sidewalls when the front frame is in the folded position.

Abstract: A system and method of executing a spread order trade is provided. The system and method of the present invention provide a profit and loss neutral model configured to dynamically and iteratively rebalance the trades associated with a spread order based on changing market conditions. According to an embodiment of the present invention, a vector-based target volume ratio is maintained by rebalancing a plurality of trades associated with instruments (or legs) of the spread order, in view of changes in the underlying markets. Maintaining a target volume ratio allow the spread order to be traded according to a profit and loss neutral model.
