In order to reinforce a rear part of a convertible vehicle, reinforcement elements are provided on both sides on a rollover protection device. The apparatus comprises first and second image display devices, and first and second mirrors. Further, an output control section selects one of the n self-synchronous data transmission lines, and mediates the reception and delivery of a second transfer request signal, a second acknowledge signal and data between the selected self-synchronous data transmission line and a self-synchronous data transmission line of a succeeding-stage section. The first application-layer data packet thus can be transmitted at substantially the same time as the initial TCP request. The present embodiments also relate to use of the compounds to treat a variety of conditions, diseases and ailments such as hematopoietic conditions and disorders. All of the pieces form parts of the packaged evidence.
