Patent number: 11185237Abstract: A method for calibrating a blood pressure monitoring system includes activating a reference monitor to perform a reference measurement of the blood pressure of a user as part of a calibration process. A wearable sensing device is activated to detect a parameter of user that is correlatable to the user's blood pressure. A processor of the user interface device processes the at least one parameter detected by the wearable blood pressure sensing device with reference to the reference measurement to determine a correlation factor that correlates the at least one parameter detected by the wearable blood pressure sensing device to the blood pressure of the user. The reference measurement includes an inflation phase, a measurement phase and a deflation phase. The processor is configured to only use the at least one parameter detected by the wearable blood pressure sensing device during the measurement phase in determining the correlation factor.Type: GrantFiled: March 6, 2018Date of Patent: November 30, 2021Assignee: Robert Bosch GmbHInventors: Christian Peters, Thomas Rocznik, Seow Yuen Yee, Igino Padovani

Patent number: 9733268Abstract: Various embodiments of the invention provide for stiction testing in MEMS devices, such as accelerometers. In certain embodiments, testing is accomplished by a high voltage smart circuit that enables an analog front-end circuit to accurately read the position of a movable proof-mass relative to a biased electrode in order to allow the detection of both contact and release conditions. Testing allows to detect actual or potential stiction failures and to reject defective parts in a Final Test stage of a manufacturing process where no other contributors to stiction issue can occur, thereby, minimizing stiction failure risks and extending the reliability of MEMS devices.Type: GrantFiled: February 20, 2014Date of Patent: August 15, 2017Assignee: Hanking Electronics Ltd.Inventors: Giorgio Massamiliano Membretti, Roberto Casiraghi, Igino Padovani

Patent number: 9689889Abstract: Various embodiments of the invention allow to reduce unwanted high-Q oscillations in capacitive MEMS sensors. In certain embodiments, stabilization of high-Q MEMS sensors is accomplished through a dedicated ultra-low power circuit that provides a bias voltage to one or more sensor electrodes during an OFF-phase. The bias voltage forces a balance condition that eliminates perturbations and enables smooth transitions that, ultimately, result in shorter sensor settling times.Type: GrantFiled: October 30, 2013Date of Patent: June 27, 2017Inventors: Roberto Casiraghi, Igino Padovani, Giorgio Massimiliano Membretti, Filippo David
