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

Publication number: 20230353979Abstract: Implementations disclosed describe techniques and systems for efficient determination and tracking of trajectories of objects in an environment of a wireless device. The disclosed techniques include, among other things, obtaining multiple sets of sensing values that characterize one or more radio signals received, during a respective sensing event, from an object in an environment of the wireless device. The sensing signals may be carried by waves with randomly selected frequencies representing a portion of all frequencies that are used as working sensing frequencies. Multiple techniques of efficient frequency interpolation and temporal interpolation are disclosed that reconstruct the sensing values to the full range of working frequencies. The reconstructed sensing values may then be used to track objects in the environment.Type: ApplicationFiled: April 29, 2022Publication date: November 2, 2023Applicant: Cypress Semiconductor CorporationInventors: Igor KOLYCH, Igor KRAVETS, Oleg KAPSHII, Kiran ULN

Publication number: 20220244078Abstract: A rotary encoder for capturing angular position of a target rotating over capacitive sensors. The rotary encoder includes a source plate. The rotary encoder includes a pair of capacitive sensors coupled to the source plate, and a target plate separated from the source plate by a gap. The target plate includes a spoke and a flange.
