A two-speed drive unit of an electric vehicle includes a planetary gear set transmission having multiple elements including a first element, a second element and a third element. A motor generator unit supplies a motive force to the planetary gear set transmission. A first stage gear transfers the motive force to the planetary gear set transmission from the motor generator unit. A second stage gear is connected through the second element to a final drive. A first torque transmitting device defining a selectable one-way clutch (SOWC) is connected to the third element.

With a cover in a closed position, a first internal gear and a first spur gear do not mesh with each other, and a second internal gear and a second spur gear do not mesh with each other. When the cover rotates by a predetermined angle around a first support shaft from the closed position, the first internal gear and the first spur gear start to mesh with each other. When the cover rotates by a predetermined angle around a second support shaft from the closed position, the second internal gear and the second spur gear start to mesh with each other.

An electric drive axle including a first gear and an idler shaft having a second gear and a third gear disposed thereon, wherein the second gear cooperates with the first gear. A clutch assembly selectively couples a planetary gear system to one of the second gear and the third gear, wherein the planetary gear system is configured to produce a predetermined gear ratio between the second gear and the third gear.

A wearable system, such as a footwear system, can employ a generator. The generator can be an electro-mechanical generator with a portion that spins to create an electricity. The portion that spins can be spun in such a manner that it does not stop, but instead a next spin beings before a previous spin completes. This can repeat until the generator reaches a terminal velocity.
