摘要:
According to the invention there is in conjunction with a pneumatic tire having a central tread, one or more radially-extending belt(s) disposed radially inwardly of the tread and an innerliner disposed radially inwardly of the belt. Apparatus for mounting an electronic tag (40) within the tire is characterized by a patch (70) having a first side (72) for mounting against the innerliner of the tire; a second arcuately-shaped side (73) and an internally threaded member (71); and an externally threaded member (64) having a portion extending from a side (74) of the tag and threadable into the internally threaded member of the patch.

An annular apparatus is embedded in a substantially nonconductive elastomeric material (22) located within the toroidal region of a pneumatic tire (10). The apparatus is coaxially positioned with respect to the tire or wheel and preferably is embedded in the tire at its equatorial plane (EP), and includes a radio-frequency transponder system (30), including an integrated circuit chip (28), and optional sensors in the chip or associated with the chip. The integrated circuit chip (28) of the transponder system (30) has at least the capacity to transmit data relating to tire or wheel identification. The antenna (26) comprises a springy steel wire or filament. Electrical leads (32) of the chips (28) are electrically associated with each end of the antenna (26).

A patch (600, 700, 700', 850, 950, 980, 1100, 1100', 1210, 1356, 1356', 1400) has an opening (620, 720, 720', 856, 956, 986, 1120, 1120', 1420) extending to a cavity (622, 722, 860, 960, 990, 1122, 1122', 1422) within the body of the patch. The transponder module is removably retained in the cavity by a resilient annular lip (624, 724, 724', 858, 958, 988, 1124, 1124', 1424) extending around the opening. End portions (742/744, 742'/744', 864/868, 942/944, 972/974, 1142/1144, 1142'/1144', 1322e/1324e, 1362/1364, 1362'/1364') of the antenna extend into the patch, and may be connected to a coupling coil (750, 750', 866, 938, 968) disposed within the patch for coupling RF signals from the antenna to a corresponding coupling coil (760, 760', 953, 1004, 1024) in the transponder module. Alternatively, the patch may have contact pads or plugs (1152/1154, 1152'/1154', 1452/1454) disposed therein for making electrical connections with corresponding contact pads (1132/1134, 1132'/1134', 1432/1434) disposed on an external surface (1106, 1406) of the transponder module.

摘要:
A method (650) of calibrating a transponder (200, 604) capable of measuring temperature data (NT) and pressure data (NP) in an object (e.g., a tire, (104)) and transmitting a data stream (Figure 3C) to an external reader/interrogator (106, 400). The transponder includes memory (238) for storing measurements, calibration data (662), transponder ID number and the like. Since the transponder combines temperature and pressure information in the 'pressure' data, the ratio NT/NP is a direct indicator of pressure-only, and is also relatively insensitive to transponder power variations. The calibration method employs a calibration chamber (602) containing reference pressure (614) and temperature (612) sensors. The transducer to be calibrated is placed in the chamber and exposed (652) to a number of predetermined temperatures and pressures (as measured by the reference sensors) at a number of calibration points. At each calibration point, a temperature reading (NT) and a pressure reading (NP) sensed by the transponder are recorded along with the reference temperature and pressure. From these readings and reference measurements the calibration constants (NT25, mT, NT/NP700,25, mP) are calculated (658).
