Patent ID: 7439852

Claim:
A flat tire alert system for detecting flat tires on trailers, comprising: a) a plurality of sensor modules, removably coupleable to an axle, and configured to sense a deflation of a tire, wherein each sensor module includes: a1) a coupling mechanism, configured to removably couple to an end of an axle; a2) a retention spring, coupled to the coupling mechanism and extending outwardly therefrom; a3) a first arm, pivotally coupled to the retention spring and extending outwardly therefrom; a4) a joint mechanism, coupled to an end of the first arm at an end opposite the coupling mechanism; a5) a second arm, pivotally coupled to the joint mechanism at an end opposite the first arm and extending outwardly therefrom; and a6) a roller, rotatably coupled to an end of the second arm opposite the joint mechanism; b) an indicator module, in communication with the sensor modules, and configured to indicate a response when the sensor module senses a deflation of a tire; and c) an alert module, in communication with the indicator module, and configured to provide an alert when the indicator module indicates a deflation of a tire.
