A mounting harness supports the side electrodes and a feed connector with the center electrode soldered to the connector. The tip includes a contoured surface for measurement and rotation on the material. The bulbous tip can rest perpendicularly or in a pivoted position on the material without a loss of measurement accuracy. A saddle ensures that a measurement of the reflection coefficient is near the bulbous tip. In use, a voltage wave generated by a vector network analyzer is guided between the electrodes toward the tip and into the material. The material reflects this voltage wave back to the analyzer. The ratio of the reflected and forward voltages forms a reflection coefficient as a baseline for measuring permittivity.

  • Patent number: 10643048
    Abstract: A fingerprint sensor and a correction method thereof are provided. The fingerprint sensor includes a sensing part to be touched by a finger, including sensing units, a processing unit, and a correction unit; the sensing unit is configured to sense, when correction starts, a fingerprint signal and output first data; the processing unit is configured to calculate, according to a mathematical model, a new correction coefficient of the corresponding sensing unit by the first data; and the correction unit is configured to correct, according to the new correction coefficient, second data output by the corresponding sensing unit. The fingerprint sensor can automatically modify a correction coefficient when a physical characteristic of the fingerprint sensor changes, thereby reducing the product return rate and prolonging the product service life, omitting a step of correction before delivery, and reducing the manufacturing difficulty and the manufacturing costs.

  • Patent number: 10620062
    Abstract: This invention provides cement-based material system for the self-sensing of the force (compressive, tensile, flexural, shear, torsional, and combinations thereof) exerted on the cement-based material. It also provides cement-based material system for weighing and a method of the self-sensing. No particular admixture is required in the cement-based material. The measurement involves using two electrodes on the same surface of the cement-based material. The force to be sensed is exerted on the cement-based material, particularly on a part of the material surface between the electrodes. The capacitance measured between the two electrodes serves as an indicator of the force. This invention also provides a method of the self-sensing of force exerted on a cement-based material.

  • Patent number: 10598754
    Abstract: A high-precision magnetometer based on a miniature Penning trap is used to measure high magnetic field strengths with very high accuracy. Due to the high precision of the developed miniature charged particle trap, magnetic field strengths can be measured with an accuracy of 1 part per million or greater, including up to and above 1 part per billion. The charged particle trap has been configured to operate with such precision in environments of high radiation, e.g., 1 MGy or above.

  • Patent number: 10573156
    Abstract: A hand held probe (200) for detecting voltage in a body of water includes voltage sensors (VS) installed in a probe head (204) with each sensor separately sensing a voltage present in the water and supplying an electrical output signal representative of the voltage level. A processor (206) processes the signals and produces an output representing a voltage gradient, a resultant electrical current, and a direction of current flow. A multiplexer (214) interposed between the sensors and processor transmits signals from the sensors to the processor in a predetermined sequence. Results of the processing including any voltage gradient, the resultant electrical current, and the direction of current flow are displayed and this information is used to determine if a currently dangerous or potentially dangerous condition exists in the water, and if a voltage is present in the water, its source.
