Abstract
Un sensor magnetico 10 incluye elementos GMR 11-18 y bobinas termicas 21-24 que sirven como elementos generadores de calor. Los elementos 11-14 y 15-18 se encuentran interconectados en puente para constituir sensores en el eje X y en el eje Y, respectivamente. Las bobinas termicas 21, 22, 23, y 24 se encuentran colocadas adyacentes a los elementos 11 y 12, a los elementos 13 y 14, a los elementos 15 y 16, y a los elementos 17, y 18, respectivamente. Las bobinas termicas 21-24, cuando son activadas electricamente, calientan principalmente los elementos adyacentes. Por lo tanto, los elementos pueden ser calentados y enfriados en un periodo corto en el cual se puede asegurar un geomagnetismo constante. Datos para la compensacion de la caracteristica dependiente de la temperatura (relacion del cambio en el valor de salida del sensor, con respecto a la variacion de la temperatura del elemento) se obtiene en base a las temperaturas de los elementos, antes y despues del calentamiento, y las salidas del sensor magnetico antes y despues del calentamiento. Subsecuentemente, las caracteristicas de temperatura de los elementos son compensadas en base a los datos. La figura mas representativa de la invencion es la numero 1.
