   <dim:field mdschema="dc" element="description" qualifier="abstract" lang="en_US">In this thesis, I describe the design, manufacture, assembly, and testing of "1WSkates," a pair of inline skates that prevent backwards motion. The defining element of 1WSkates is the use of a one-way bearing which, along with a fixed axle, prevents certain wheels from rolling backwards. The axle is custom-shaped to lock into an existing inline skate housing. The one-way bearing is attached to the wheel with a custom fitting. The complete 1WSkates allow a user to walk up an incline and roll down the other side, and to use a nordic skiing motion on flat terrain.</dim:field>
