Patent number: 11877840Abstract: An apparatus includes an interface and a processor. The interface is configured for exchanging signals with: (i) a probe, which is inserted into a body of a patient and includes a flexible distal-end assembly, wherein the distal-end assembly comprises a magnetic position sensor and two or more intra-body electrodes, and, (ii) multiple body-surface electrodes attached externally to the body of the patient. The processor is configured to estimate, based on the signals exchanged with the probe, a spatial displacement of the magnetic sensor between consecutive measurements, and to estimate a position of the distal-end assembly in the body based on (i) the signals exchanged with the intra-body electrodes and the body-surface electrodes, (ii) a-priori known spatial relationships between two or more of the intra-body electrodes of the probe and (iii) the estimated spatial displacement of the magnetic sensor.Type: GrantFiled: May 29, 2018Date of Patent: January 23, 2024Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Doron Moshe Ludwin, Gal Fleishon, Meir Bar-Tal, Goren Cohn, Menachem Schechter, Daniel Osadchy

Patent number: 10684986Abstract: A method, including configuring, in a memory, a first buffer to store first buffer data, a second buffer to store second buffer data, and a variable indicative of a persisted size of real-time data persisted to a storage device. On the storage device, a file is configured to store the real-time data and a field is configured to store the variable. A stream of the real-time data is received, and the stream is appended to the first buffer data. Upon meeting a write criteria, the first buffer data in is swapped with the second buffer data, a buffer size of the second buffer data is added to the variable, and the second buffer data is conveyed from the second buffer to a write cache. Upon meeting a commit criteria, the stream stored in the write cache is appended to the file, and the variable is persisted to the field.Type: GrantFiled: August 28, 2013Date of Patent: June 16, 2020Assignee: Biosense Webster (Israel) Ltd.Inventors: Eliyahu Ravuna, Goren Cohn, Roey Lehman, Yochai Alon Timmer
