Abstract

SENSOR DE POSIçãO E MáQUINA DE LAVAR. A presente invenção refere-se a um dispositivo de sensor de posição para determinar uma posição de um objeto móvel, em que o dispositivo de sensor de posição compreende uma fonte de campo magnético adaptada para ser fixada em um objeto móvel, um primeiro detector de campo magnético localizado em uma primeira posição e adaptado para detectar um primeiro sinal de campo magnético característico de um campo magnético gerado pela fonte de campo magnético na primeira posição, um segundo detector de campo magnético localizado em uma segunda posição e adaptado para detectar um segundo sinal de campo magnético característico de um campo magnético gerado pela fonte de campo magnético na segunda posição, e uma unidade de determinação de posição adaptada para determinar uma posição da fonte de campo magnético com base em uma comparação do primeiro sinal de campo magnético e do segundo sinal de campo magnético.
