A holder and reader for two or more data cards for a radio communication device, the holder including a body having formations for releasably carrying the two or more data cards and being adapted to be removably installed in the data card reader of the device. The automatic diagnostic system includes a fault detection unit for detecting an individual fault and a test unit for performing a test to find a cause of the individual fault in the network element in which the individual fault has occurred. Rather, deinterlacing in accordance with the teachings of the present invention uses, for example, four localized input pixel values to produce an output pixel value that minimizes spatial artifacts. The second version utilizes a highly conductive material that has a higher rate of conductivity than that of aluminum. The novel bicycle, comprising a frame having front and rear sockets, a seat mounted into the rear socket, and a handlebar mounted in the front socket, can advantageously be adjusted so that a rider can adopt different riding positions to simulate outdoor bicycle riding conditions. One method includes initially rendering the scene to create color and depth texture maps and creating mip-map layers for the color texture map.
