Abstract

resumo patente de invenção: "dispositivo e método para manipulação de produção de urina". a presente invenção refere-se a método para automaticamente, com a ajuda de um processador, determinar uma degeneração de superfície de uma primeira superfície de um sistema de manipulação de urina, a primeira superfície sendo planejada para entrar em contato com a urina, o método compreende as etapas principais seguintes: a) medir repetidamente um ou mais valores capacitivos da primeira superfície, formando medições capacitivas; b) armazenar todos, ou instantes representativos das medições capacitivas, c) decidir, com base nas mudanças das medições capacitivas armazenadas, que uma degeneração de superfície significativa da primeira superfície ocorreu.
