A touch applied to a node of the panel changes a capacitive coupling between two electrodes (a drive electrode and a sense electrode) of the touch panel. The drive unit delivers a drive signal, which may comprise one or more drive pulses, to the drive electrode. The sense unit couples to the sense electrode, and generates a response signal that that is used to accumulate charge in a charge accumulator to provide an accumulated signal. The accumulated signal is responsive to the capacitive coupling between the electrodes, and is measured to provide an indication of a touch at the node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High speed low power multi-touch touch device and controller therefor","description":"A touch-sensitive device includes a touch panel, a drive unit, a sense unit, and a measurement unit.
