Abstract: A truck comprises a tractor and a trailer hitched thereto. At least one tire is mounted on each end of each of the tractor's axles and at least one tire is mounted on each end of each of the trailer's axles. A sensor is associated with each tire. Each sensor acquires tire-condition data about its respective tire and transmits this tire-condition data to a proctor. The proctor can coordinate realtime tire-condition displays, facilitate flagging of tire-condition problem tires in a fleet yard, and/or allows large data downloads for historical evaluation.

Abstract: A tire-condition-ascertaining cartridge (100) comprising a scaffoyer structure which performs both scaffolding and fluid-foyer-forming functions. The scaffoyer (600) includes planks and/or derricks which properly posture a first fitting (200), a second fitting (300), an electronics assembly (400), and a power source (500) during cartridge construction. The scaffoyer (600) also forms a fluid foyer to the sensing site and this foyer can be tested for fluid integrity (e.g., leaks) prior to creating the housing capsule (800).
