Abstract: An exercise machine has a first frame member, a second frame member that is movable with respect to the first frame member, and a locking device having at least one cam that is rotatable into and between a locked position in which the cam abuttingly engages and thereby retains the second frame member in position with respect to the first frame member and an unlocked position in which the cam is spaced from and thereby frees the second frame member for movement with respect to the first frame member. The cam has an engagement surface with a contour that follows a logarithmic spiral curve defined by the following parametric equations: x(t)=r(t)cos(t)=aebt cos(t), and y(t)=r(t)sin(t)=aebt sin(t), wherein e is the base of natural logarithms and a and b are arbitrary positive real constants.

Abstract: Two vehicle systems concept development processes (VSCDPs) are provided. Both VSCDPs are for a company having a global marketing and sales unit, a business planning unit, and an engineering unit. The global marketing and sales unit, the business planning unit, and the engineering unit in the first VSCDP utilize system program planning, requirements driven customer ready development, and system design optimization and manufacturing planning techniques in combination with predetermined inputs to create outputs. The global marketing and sales unit, the business planning unit, and the engineering unit in the second VSCDP utilize project ready, concept demonstration ready, and application ready techniques in combination with predetermined inputs to create outputs. The engineering unit includes a vehicle system management unit, a lead vehicle system engineer, a vehicle functional system engineer, an enabling technologies/research group, and a strategic business unit (SBU) engineering and strategic partners group.

Abstract: A jump-start assembly 13 for use within a vehicle 10 of the type having a pair of dissimilar batteries 12, 14. Assembly 13 allows the vehicle 10 to be selectively jump-started and electrical charge to be communicated to the battery 14 by the use of a single battery 62, 90.

Abstract: A bicycle having a pair of wheels and a frame formed of two crossing bars that are detachable from each other so as to form a separate unicycle and a pedal bike, one of which includes a handle bar at a top, and the other a seat at its top, while each has one wheel at a lower end.
