  • Patent number: 11960691
    Abstract: A technique for reading the columns (12) and rows (14) of a touch sensor (10) provides several advantages, including scalability to touch sensors with high column/row counts. A simultaneously applied set of column input signals (24) yields a corresponding set of column output signals (34) that are combined into a combined column signal (38) that is transformed into the frequency domain after digitization, to yield column values (48) corresponding to the respective touch sensor columns (12). The same process applied with respect to the touch sensor rows (14) yields a set of row values (50), with evaluation of the frequency-domain column and row values (48, 50) providing the basis for detecting touch inputs to the touch sensor (10).

  • Patent number: 11962475
    Abstract: The properties of a plurality of operational units are estimated by generating a central system state graph model representing the properties of the plurality of operational units as probabilities of transitions between states for the plurality of operational units, where the states represent operational data. Then a respective updated system state graph model is generated for each of the plurality of operational units, based on the central system state graph model and based on new operational data for the respective operational unit. A distance measure is determined between the respective updated system state graph models. If the distance measure fulfils a divergence criterion, a plurality of new central system state graph models are generated, each representing the properties of a respective subset of the plurality of operational units as the probabilities of transitions between states for the respective subset of the plurality of operational units.
