Patent number: 11972078Abstract: A capacitance sensing device includes a transmit (TX) generator for generating a sequence of receive (RX) signals by applying each TX signal pattern in a sequence of TX signal patterns to a set of sensor electrodes. For each TX signal pattern in the sequence of TX signal patterns, and for each subset of three or more contiguous sensor electrodes of the set of sensor electrodes, the TX generator applies to the subset one of a first excitation signal and a second excitation signal. The plurality of subsets includes at least half of the sensor electrodes in the set of sensor electrodes. The capacitance sensing device also includes a sequencer circuit coupled with the TX generator. For each TX signal pattern in the sequence of TX signal patterns, the sequencer circuit determines a next subsequent TX signal pattern in the sequence based on a circular rotation of the TX signal pattern. The capacitance sensing device also includes a processing block coupled with the TX generator.Type: GrantFiled: June 22, 2018Date of Patent: April 30, 2024Assignee: Cypress Semiconductor CorporationInventors: Viktor Kremin, Volodymyr Bihday, Ruslan Omelchuk, Oleksandr Pirogov, Vasyl Mandziy, Roman Ogirko, Ihor Musijchuk, Andriy Maharyta, Igor Kolych, Igor Kravets

Patent number: 11868561Abstract: Apparatuses and methods of multi-phase scanning of a touch panel are described. One apparatus selects a sequence having a number of one values, negative one values, and zero values. The one values correspond to an in-phase drive signal, the negative one values correspond to an opposite-phase drive signal, and the zero values correspond to a reference signal (e.g., reference voltage or ground). A sum of the sequence is equal to zero. The apparatus applies one of the in-phase drive signal, the opposite-phase drive signal, or the reference signal to each of a first set of electrodes at a first stage according to the sequence. The apparatus rotates the sequence to obtain a rotated sequence and applies one of the signals according to the rotated sequence. The apparatus receives sense signals to detect a presence of an object on the touch panel.Type: GrantFiled: May 26, 2021Date of Patent: January 9, 2024Assignee: Cypress Semiconductor CorporationInventors: Volodymyr Bihday, Andriy Maharyta, Igor Kravets, Mykhaylo Krekhovetskyy, Ihor Musijchuk
