    Abstract: Strain sensors are provided that include a flexible substrate, a sheet affixed to the flexible substrate, and two or more microelectrodes printed at spaced locations onto either the sheet or the flexible substrate, wherein the sheet includes a carbon nanotube network, the sheet having a top side and an opposing second side. The two or more microelectrodes are printed at spaced locations onto the top side of the sheet or onto a side of the flexible substrate facing the second side of the sheet. Methods are provided for fabricating a strain sensor wherein the sheet is arranged between the printed microelectrodes and the flexible substrate or wherein the second side of the sheet is arranged atop or across the printed microelectrodes. Methods are also provided for measuring strain in a structure via the strain sensors affixed or integrated therein.

    Abstract: A battery cell is configured to operate in within an electronic device. Determining the status of the battery cell includes using a strain gauge attached to the battery cell. A value of the dimension of the battery cell is established by use of the strain gauge. The status of the battery cell is determined based on the established dimension value compared to a reference value and a threshold related to the dimension of the battery cell. Related methods, devices and/or computer program products are described.

    Abstract: This application describes a state deviation technique for identifying transient instabilities in power systems. Such instabilities may result from disturbances such as external faults and power swing conditions. Detection of transient instabilities is based on the direction of change of phase angle of a machine such as a generator at an equilibrium point. Method and apparatus as disclosed may also be used for assessing system-wide transient stability of a power system or portion thereof.

    Abstract: A mixer sensing assembly of a mixer for mixing a wellsite fluid in a tank at a wellsite is provided. The mixer includes a shaft driven by a driver and a paddle operatively connectable to the shaft and rotatable therewith. The sensor assembly includes a mount operatively connectable to the shaft, a fluid interface, and a mixing sensor. The fluid interface is responsive to flow of the wellsite fluid passing thereby, and is connectable to the mount. The mixing sensor is connectable to the mount, the fluid interface, and/or the shaft to measure a strain applied to the thereto whereby fluid parameters of the wellsite fluid may be determined. The wellsite fluid may be mixed moving the components in the tank with the mixer, and measuring a strain on the mixer by detecting movement of the sensor assembly.
