A foldable two wheeled scooter includes a steering post with a front wheel at a lower end and handlebars at an upper end. The reinforcement filaments are arranged in an essentially parallel manner to each other at an angle between 40\xb0 and 80\xb0 to the direction of the periphery of the rolling-lobe flexible member. The data storage device converts the virtual block address to a physical block address of the data storage device using a mapping associated with the access key. The user uses a short message in a mobile communication network to remotely control a vehicle. The grids are then recursively checked to see if they cover a range of interest. Subsequently, every time the data amount stored in the first memory reaches a predetermined amount, the quantization step is increased, and the processing is repeated.
