A method and system is disclosed for efficiently transferring a sequence of data words from an I/O device to sequential addresses in a main memory via an I/O bridge. The sequence of data words to be transferred includes one or more subsequences of data words. Each subsequence of data words include only data words destined to addresses of the main memory in which data words of only one data line are stored. The I/O bridge has control logic for receiving a first subsequence of data words corresponding to a currently owned data line and for claiming ownership in one or more of the very next data lines corresponding to the next subsequences of data words to be transferred from the I/O device. The I/O bridge also has a buffer memory for storing a subsequence of the sequence of data words received from the I/O device. The control logic maintains in a pre-own tag array a list of the data lines in which ownership has been successfully claimed and a list in a buffer tag array of storage locations in the buffer memory allocated to receiving data words of particular subsequences of the sequence of data words from the I/O device.

A ridable multi-functional wheelchair assembly, aside from being used as a general wheelchair, may be converted into a pedicab by connecting a rear wheel thereto; the pedicab may be further converted into a tread wheel by suspending the rear wheel from the ground or floor with an U-shaped supporter.
