Abstract
"MéTODO E APARELHO PARA A MEDIçãO DE TEMPERATURA COM UM DISPOSITIVO DE CIRCUITO INTEGRADO" Um sensor de temperatura é implementado com um componente sensível à temperatura (Q1) de um chip de IC que funciona como um transponder de radiofreq³ência (RF) 200 capaz de medir parâmetros associados com um objeto e transmitir dados para uma leitora/interrogador externo (106,400). Em uso com um pneu (104), o transponder mede temperatura e pressão dentro do pneu. O transponder inclui conjunto de circuitos (226) para controlar janelas de tempo (W~ T~ e W~ P~) durante as quais as medições de temperatura e pressão em tempo real são feitas e para armazenar (236) dados de calibragem, número ID do transponder e semelhantes e para transmitir essa informação em um fluxo de dados (figura 3C) para a leitura/interrogador. Uma condição de temperatura excessiva pode também ser sentida (MTMS 218) e incluída no fluxo de dados. O conjunto de circuitos do transponder é preferivelmente implementado em um único chip de IC (204), usando tecnologia CMOS, com poucos componentes externos ao chip de IC. O transponder é preferivelmente passivo, derivando sua energia de operação de um sinal de RF fornecido pela leitora/interrogador externo. Os dados (N~ T~) indicativos da temperatura e os dados (N~ P~) indicativos da pressão são ambos transmitidos para a leitora/interrogador, junto com dados de calibragem. Os dados de calibragem armazenados pelo transponder e transmitidos no fluxo de dados é uma inclinação de N~ T~/N~ P~, ou a resposta "em proporção" da contagem de temperatura dividida pela contagem de pressão, que é determinada durante a calibragem do transponder."METHOD AND APPARATUS FOR TEMPERATURE MEASUREMENT WITH AN INTEGRATED CIRCUIT DEVICE" A temperature sensor is implemented with a temperature sensitive component (Q1) of an IC chip that functions as a 200 radio frequency (RF) transponder capable of measuring parameters associated with an object and transmit data to an external reader / interrogator (106,400). In use with a tire (104), the transponder measures temperature and pressure inside the tire. The transponder includes circuitry (226) to control time windows (W ~ T ~ and W ~ P ~) during which real-time temperature and pressure measurements are made and to store (236) calibration data, number Transponder ID and the like and to transmit this information in a data stream (figure 3C) for reading / interrogating. An over temperature condition can also be felt (MTMS 218) and included in the data stream. The transponder circuitry is preferably implemented on a single IC chip (204), using CMOS technology, with few components external to the IC chip. The transponder is preferably passive, deriving its operating energy from an RF signal provided by the external reader / interrogator. Temperature data (N ~ T ~) and pressure data (N ~ P ~) are both transmitted to the reader / interrogator, along with calibration data. The calibration data stored by the transponder and transmitted in the data stream is an N ~ T ~ / N ~ P ~ slope, or the "proportionate" response of the temperature count divided by the pressure count, which is determined during calibration of the transponder.
