Abstract: A thermoplastic composite welding microwire temperature measurement system broadly comprises a plurality of moveable antennae configured to transmit interrogation signals, a rail system including a motorized linear stage configured to move the antennae along a weld line, and a reader or processor configured to determine a position of the microwire temperature sensor and determine a welding temperature based on response signals of the sensor. The interrogation signal corresponds to two different maximum ramp current amplitudes to create two re-magnetization pulses non-overlapping in the time domain.

Abstract: Temperature measurement systems (20) include a temperature sensor (22) and an electronic signal interrogator (24). The temperature sensor (22) has a transponder (26) equipped with an antenna (28), and a separate parasitic antenna (32) with a temperature-sensitive transducer (34, 68-74, 78a-84a), while the interrogator (24) has a transmitter (42) and antenna (40). The sensor (22) is designed to be placed in thermal contact with an object to be temperature-measured, with the interrogator (24) placed in proximity to the object. The systems (20) may be used with food servingware domes (88, 114), which can be preheated and placed over a food-bearing plate to maintain the temperature of the food.

Abstract: A wiper assembly having a wiper with an inductively heatable portion, and an induction heating device including an induction work coil which is configured to be placed near the wiper to inductively heat the inductively heatable portion. The inductively heatable portion may be in the wiper blade, the wiper arm which supports the blade, or both. The induction work coil may be placed on or near the windshield or other surface which is cleaned by the wiper and may heat the wiper regardless of its position or only when the wiper is at a specific location such as its retracted “rest” position. The wiper assembly may also include a temperature sensor for sensing a current temperature of the wiper and control circuitry associated with the induction heating device for controlling operation of the work coil.

Abstract: Induction heatable clothing items such as footwear (22) and apparel (160) are provided which include a clothing body having an induction heatable element (36, 108, 112, 114, 116) and preferably having heat retentive material containing phase change material, wherein the element (36, 108, 112, 114, 116) is operable to be heated when subjected to an alternating magnetic field. The clothing items (22, 160) are heated using induction heaters (26, 84). In preferred forms, wireless temperature sensing is used to control heating of the items (22, 160). To this end, the heating elements (36, 108, 112, 114, 116) may be provided with RFID tag/temperature sensor assemblies (58, 60, 110), and the induction heaters (26, 84) are equipped with correlated RFID reader/writer devices (80). Alternately, microwire temperature sensors (120) may be used with the induction heaters (26, 84) having microwire detectors. In other embodiments, temperature monitoring is achieved using impedance detection feedback control.
