  • Patent number: 10690728
    Abstract: A plasma-generating device capable of detecting a short circuit or electrical discharge of a cable. In response to a detection voltage detected by a current transformer becoming equal to or greater than a threshold voltage, a touchscreen panel of the plasma-generating device reports a current abnormality. When a short circuit or a discharge occurs between the first cable and the second cable, which are a pair of cables, an induced current flows through the shield member by electromagnetic induction. Therefore, the detector can detect a current abnormality due to a short circuit or electrical discharge between the first cable and the second cable.

  • Patent number: 10649016
    Abstract: A probe is provided for measuring permittivity of a dielectric material. The probe includes side electrodes and a pivotable center electrode with a bulbous tip to contact the material. 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: 10197609
    Abstract: A system and method for incorporating occupancy-detecting technology into furniture is provided. More particularly, the invention relates to direct-connect device, system, and method for determining presence with respect to an automated furniture item, such as a recliner mechanism. In some aspects, a sensor is provided based on coupling one or more conductive features to a control component of the capacitance detector control component. A controller may determine the corresponding response based on occupancy detection and/or presence detection. A processor may receive information regarding changes in capacitance and determines when a change in voltage satisfies a threshold. Based on a determination of occupancy and/or presence, a variety of corresponding features of the adjustable recliner may be activated.

  • Patent number: 9983111
    Abstract: A low-profile shear-sensing unit includes a floating plate surrounded by a frame and a displacement sensor that measures in-plane movement of the floating plate. Covered with a surface sample, the floating plate is displaced by the friction drag (i.e., shear) on the surface caused by the flow of fluid and the in-plane displacement is measured by the displacement sensor. The shear force on the sample surface is then obtained by multiplying the measured displacement and the spring constant of the flexure beams, which suspend the floating plate. The floating plate and the flexure beams are formed out of one plate or substrate to achieve monolithic construction with a beam geometry that leads to a high-resolution measurement.
