Abstract: A slider row bar de-bond fixture has a base plate; a row of separator walls formed on a top surface of the base plate and spaced one another for separating a plurality of slider row bars; and a plurality of grooves defined between the adjacent separator walls for receiving the slider row bars respectively. Each of the separator walls has a free top end with a smaller depth than its bottom end. Preferably, each of the separator walls has a structure of trapezoid or triangular form in cross section. The slider row bar de-bond fixture occupy a little room and more importantly, receive the debonded slider row bars more safely and without overlapping.

Abstract: An add-on kit comprising a (1) ring of (2) magnets (easy to install) is installed onto a (6) wheel of bike or car. An arrangement of (3) electromagnets and (5) inductors (detectors) is installed onto the (4) fork of a bike or suspension of car in the proximity of the ring. By turning the (3) electromagnets on and off and controlling the on-time and the field strength, a force that assists the wheel in rotating is produced. With the electromagnets turned-off, the moving ring of permanent magnets also provides for regenerative braking. With the bicycle mounted on an elevated stand, and the controlled timing of the electromagnets programmed to induce a force in the backwards direction, a user can use his bike as an exercise machine, gaming/training apparatus, or just to recharge the batteries.
