Sample processing devices including process chambers having bypass slots and methods of using the same are disclosed. The invention provides a microsystem platform and a micromanipulation device for manipulating the platform that utilizes the centripetal force resulting from rotation of the platform to motivate fluid movement through microchannels. A first unit then calculates an air resistance value by measuring aerodynamic force data which the vehicle receives from air based on a pressure value of air sensed by the pressure sensor and driving information depending on the driving of the vehicle, and a method thereof. The polypeptides may be used for the preparation of pharmaceutical compositions, and for treatment of a subject having a pathology mediated by TNF, such as treatment of rheumatoid arthritis.
