Abstract: A motorized wheel assembly adaptable to skateboards provides drive motor and power sources and controls for the directed control of forward or backward propulsion of the skateboard using throttle and braking controls, the motorized wheel, and all skateboard wheels. Weight transfer assemblies for the motorized wheel transfer a portion of a skateboard rider's weight through the front mounted motorized wheel to the ground surface creating sufficient traction for the motorized wheel to propel the skateboard. One weight transfer assembly embodiment provides a pivoting, compression based mounting bracket. Separate embodiments of the weight transfer assemblies include single or dual shock absorbers.

Abstract: A subscriber line interface circuit is provided that posses an output impedance that may be greater than about 2.2 Kohms at at least some frequencies associated ADSL communications. In at least some embodiments, such ADSL frequencies include frequencies greater than about 30 KHz. In some embodiments, the subscriber line interface circuit includes an output driver that provides voice signals on a telephone line on which digital data is also provided by a data driver and a filter coupled to the output driver wherein the output impedance of the subscriber line interface circuit is greater than about 2.2 Kohms at at least some frequencies greater than 30 KHz.
