Publication number: 20230218181Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of controlling an inflation rate in a blood pressure measurement. An inflatable bladder of the blood pressure measurement device defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage. A pressure sensor of the blood pressure measurement device is configured to obtain blood pressure measurements, and a pump of the blood pressure measurement device is configured to inflate the inflatable bladder and control an inflation rate by controlling at least one of a duty cycle, a voltage, or a drive frequency.Type: ApplicationFiled: January 13, 2023Publication date: July 13, 2023Inventors: Dan Stefan Tudose, Xi Zhang, Keith Adam Wong, Andrew Larsen Axley, Peter W. Richards, Conor Joseph Heneghan, Radu Dobroiu, Alexandru-Mihai Solot

Publication number: 20220409074Abstract: An aspect of the disclosure pertains to detecting a position of a blood pressure measurement device. An inflatable bladder of the blood pressure measurement device defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage. A pump may initiate inflation of the inflatable bladder when one or more accelerometers and/or one or more proximity sensors determine that the blood pressure measurement device is within sufficient proximity or elevation to a user's heart and stationary.Type: ApplicationFiled: July 8, 2022Publication date: December 29, 2022Inventors: Xi Zhang, Keith Adam Wong, Andrew Larsen Axley, Dan Stefan Tudose, Conor Joseph Heneghan

Publication number: 20220392078Abstract: Illustrative embodiments are directed to methods, apparatus and computer program products for segmentation of X-ray tomography images via multiple reconstructions. A computed tomography scan of an object is received. The computed tomography scan is processed to generate an absorption reconstruction and a phase reconstruction from the computed tomography scan. First and second sets of seeds within the phase reconstruction are labeled as corresponding to a first phase by thresholding below a first threshold and corresponding to a second phase by thresholding above a second threshold, respectively. The absorption reconstruction is segmented automatically using an algorithm based on the first set of seeds, the second set of seeds and the absorption reconstruction. A final segmentation is produced based on a combination of the absorption reconstruction and the phase reconstruction.Type: ApplicationFiled: June 4, 2021Publication date: December 8, 2022Inventors: Dan Stefan Bolintineanu, Enrico C. Quintana, Sharlotte Lorraine Bolyard Kramer, Robert Waymel, Kevin Nicholas Long

Patent number: 10874308Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of obtaining pulse information from a blood pressure measurement. An inflatable bladder defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage, where the inflatable bladder is inflated to a pressure greater than a maximum amplitude pressure from oscillometric data in a pressure profile. The inflatable bladder may be deflated and then re-inflated to a target pressure and held at the target pressure to generate pulse information, or the inflatable bladder may be deflated to the target pressure and held at the target pressure to generate the pulse information.Type: GrantFiled: December 27, 2017Date of Patent: December 29, 2020Assignee: Fitbit, Inc.Inventors: Xi Zhang, Keith Adam Wong, Andrew Larsen Axley, Dan Stefan Tudose, Conor Joseph Heneghan, Radu Dobroiu, Alexandru-Mihai Şolot

Publication number: 20070137970Abstract: An actuator for selectively causing axial compression of friction elements in a clutch is disclosed. The actuator comprises a pair of beveled wedge washers and a bearing race supported between the washers. The race supports conical bearing rollers in a generally radial orientation. An actuator plate is mounted for rotation relative to the bearing race and includes bearing ramp surfaces that are operable to move the conical bearing rollers radially inwardly thereby forcing the washers to move apart axially and to thereby cause compression of and torque transfer through the friction elements. A clutch including the actuator is well suited for inclusion in a transfer case.Type: ApplicationFiled: December 21, 2005Publication date: June 21, 2007Applicant: DYMOS Co., Ltd., d/b/a DYMOS of AmericaInventors: Dan Stefan, Thomas Bowen, Jason Davis
