Publication number: 20190205198Abstract: Disclosed are a method and electronic device for determining a faulty state of a storage device. A first time length of a first access to a set of blocks of a storage device is determined. Then, the first time length of the access and a threshold time length are compared. If the first time length exceeds the threshold time length, it is determined that the blocks are in a potential faulty state.Type: ApplicationFiled: September 5, 2016Publication date: July 4, 2019Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Yantao WANG, Jing LIU, Lijun SHEN

Publication number: 20180292345Abstract: A method and device for measuring a substance's concentration in a fluid. The method includes first passing a sample to be measured through a chemical sensor at least twice and recording the response value each time; forming a simultaneous equation set using the equation relation between the response value obtained during each measurement and the concentration of the substance, and the mass equation relation satisfied by the concentration change caused by a physical, chemical reaction during each measurement and by the change of the mass, electric quantity, and heat; solving for the concentration of the substance measured and the sensor calibration parameter. The method, used as an absolute measurement method, can be applied to calibrate the sample concentration of a fluid, overcomes the effects on the measurements caused by temperature, humidity, pressure, and some interfering gas, requires no sensor calibration, and substantially enhances the measurements' stability and reliability.Type: ApplicationFiled: April 26, 2018Publication date: October 11, 2018Applicant: Sunvou Medical Electronics Co., Ltd.Inventors: Ray Xie, Jie Han, Lijun Shen, Yiping Han
