The present invention provides a method for inhibiting the activity of cyclooxygenase-2 and other proinflammatory factors in a mammal. A virtual-private-network tunnel extending between the mobile node and the home agent is established, wherein the home agent comprises a VPN function. The emitters on each side are spaced sufficiently apart from one another to provide accurate pose information. An installation space includes the apparatus and a method is implemented to provide safety measures during gas release from the vehicle battery. Each time a symbol is dealt, a marker for the corresponding lane is moved forward one station until one marker reaches a finish position.
