  • Patent number: 11530958
    Abstract: An intelligent optical fiber tactile sounding system and a method thereof, and belongs to the field of intelligent optical fiber sensing. The system includes a flexible optical fiber tactile sensing array, a photoelectric detection system, an intelligent pressure analysis software and an acoustic emission system; a small-scale distributed tactile sensing array is constructed by embedding a fiber-core mismatched optical fiber interferometric sensor into a flexible substrate material and performing sensing region division for an asymmetrical structure with an optical fiber structure as a delimiting line; a tactile sensor transmits tactile signals to the photoelectric detection system in the form of optical signals, the photoelectric detection system inputs these pressure signals into the intelligent pressure analysis software to determine a region and a size of a tactile source, and then sends an instruction to the acoustic emission system to enable the acoustic emission system to emit different sounds.

  • Publication number: 20190205198
    Abstract: 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.

  • Publication number: 20180292345
    Abstract: 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.

  • Publication number: 20110197649
    Abstract: A self-calibrating gas sensor comprises a steady current measuring gas line composed of valves, pumps and a current-type electrochemical sensor, and a coulomb analyzing gas line composed of said valves, said pumps, said current-type electrochemical sensor and a sample chamber. The two gas lines can be interchanged between measurement and analysis by controlling valves. The sensor can measure gas concentrations, and self-calibrate its sensitivity without the need of standard gases for external calibration.
