Abstract: A skateboard wheel system for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels. The skateboard wheel system includes a rim member, manufactured in a plurality of designs and appearances, with a bearing pressed into both a first end and a second end and wheel member pressed about the rim member retained by a ring member. The rim member is comprised of an aperture for mounting the skateboard wheel system to the truck of the skateboard, a flange element located towards the first end for retaining the wheel member and a first threads towards the second end for retaining the ring member. The wheel member has a rib integrated to an interior surface for retaining it to the rim member. The ring member includes a plurality of tool apertures to be utilized while assembling the ring member to the rim member.

Abstract: The invention relates to switchable waste gas exchangers which can are arranged and used, in particular, in exhaust gas recirculation lines in internal combustion engines, especially in motor vehicles.

Abstract: A method and apparatus for implementing trimming circuits. More particularly, embodiments of the present invention provide a transistor that supplies sufficient current to trim a trimming fuse when the transistor is powered up and after it receives a select signal at its gate. When the trimming fuse is trimmed, it decouples undesired electrical connections in a circuit. Also provided is a delay structure that adds an RC delay to the select signal. The RC delay is of a sufficiently long duration so as to decrease the switching speed of the transistor. The delay structure also provides a pass filter to filter power and voltage spikes in the select signal.
