Patent ID: 6911902

Claim:
An apparatus for securing a housing to a wheel supporting a tire that is inflated by an inflation gas pressure, comprising: a first cylinder coupled to the housing, the first cylinder containing a first piston and a first connecting rod that is movable in first and second directions; a biasing device providing a pressure less than the inflation gas pressure for urging the piston and the first connecting rod in the first direction, the piston and the first connecting rod being movable in the second direction by the inflation gas pressure; and a tether coupling together the housing, the wheel, and the first connecting rod such that when the tire is uninflated, the tether is made slack by the movement of the first connecting rod in the first direction, and when the tire is inflated by the inflation gas pressure, the tether is drawn taut by the movement of the first connecting rod in the second direction, thereby securing the housing to the wheel.
