Patent number: 10564179Abstract: A sensor such as an accelerometer includes a proof mass located opposite a plurality of electrodes located on a substrate. Some of the electrodes are auxiliary electrodes that apply an alternating current auxiliary signal to the proof mass while other electrodes are sense electrodes that sense movement of the proof mass. When a residual voltage is not present on the proof mass or on the sense electrodes, the forces imparted by the auxiliary signal onto the proof mass are substantially balanced. When the residual voltage is present on the proof masses, forces at a first harmonic frequency of the auxiliary signal are sensed by a sense electrode of the sensor. A self-test is failed if the sensed forces exceed a threshold.Type: GrantFiled: November 29, 2016Date of Patent: February 18, 2020Assignee: PANASONIC CORPORATIONInventors: Giacomo Gafforelli, Luca Coronato, Adolfo Giambastiani

Patent number: 10533955Abstract: A method for use in measuring a composition of a multiphase fluid which includes flowing a multiphase fluid through a fluid flow path defined by a wall of a fluid conduit is disclosed. The wall includes an electrically non-conductive material. The method includes establishing an electromagnetic field which extends through the electrically non-conductive material of the wall of the fluid conduit into the fluid and measuring a property of the electromagnetic field over a measurement time period. The method also includes transmitting additional energy through the fluid over the measurement time period independently of the electromagnetic field and measuring the additional energy transmitted through the fluid over the measurement time period. The method may be used to unambiguously determine a composition of a multiphase fluid which has different components.Type: GrantFiled: February 26, 2016Date of Patent: January 14, 2020Assignee: M-Flow Technologies LtdInventors: Alan Parker, Giles Edward, Arnault Tremolet, Alex Wall-Clarke

Patent number: 10520343Abstract: The present invention provides a thermal flowmeter having good measurement accuracy by reducing deviation in the flow velocity distribution of a gas under measurement flowing through an auxiliary passage. An auxiliary passage 330 for taking in a portion of a gas under measurement IA flowing through a main passage 124 has a curved passage 32a that bends toward a flowrate measurement element 602. The curved passage 32a has a resistance portion 50 formed therein that applies resistance to the flow of the gas under measurement IA flowing through the outer peripheral side CO of the curved passage 32a so that the pressure loss of the gas under measurement IA flowing through the outer peripheral side CO is high compared to that of the gas flowing through the inner peripheral side CI of the curved passage 32a.Type: GrantFiled: July 10, 2015Date of Patent: December 31, 2019Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Takeshi Morino, Shinobu Tashiro, Masashi Fukaya, Atsushi Inoue, Masanobu Ino, Naoki Saito
