Title (EN) FREQUENCY HOPPING ALGORITHM FOR CAPACITANCE SENSING DEVICES
(FR) ALGORITHME DE SAUT DE FRÉQUENCE POUR DISPOSITIFS DE DÉTECTION DE CAPACITÉ
Abstract: front page image
(EN)Apparatuses and methods of frequency hopping algorithms are described.. One method listens to a noise level on multiple electrodes of a sense network at multiple operating frequencies. The method then selects one of the frequencies with a lowest noise level for scanning the electrodes to detect a conductive object proximate to the electrodes.
(FR)La présente invention concerne des appareils et des procédés associés à des algorithmes de saut de fréquence. Selon l'invention, un procédé écoute un niveau de bruit sur de multiples électrodes d'un réseau de détection à de multiples fréquences de service. Le procédé choisit ensuite l'une des fréquences ayant le niveau de bruit le plus bas pour balayer les électrodes afin de détecter un objet conducteur se trouvant à proximité des électrodes.
