A one-way bearing or clutch is provided to decouple a continuously variable transmission from the final drive member during reverse torque conditions. The subject invention further reveals a sterile intravascular starter kit, said kit being comprised of the adhesive tape for an intravascular catheter, a tourniquet, a gauze pad, an antiseptic skin preparation device, optionally a towel, and a clear occlusive dressing. Microwave chokes and microwave suppression tunnels are provided for limiting the escape of volumetric heating energy such as microwave energy into the surrounding area and into the ventilation system. Each one of the controllers has a memory refresh section for refreshing the data storage elements in the common memory. The method is particularly applicable to a series of quantized transform coefficients where clusters are likely to occur.
