    摘要： A linear detector element includes an outer sheath having a first end and a second end, one or more shape memory responsive elements within the outer sheath and between the first end and the second end and first and second conductive wires passing through at least a portion of the outer sheath and through the one or more shape memory responsive elements. The one more shape memory responsive elements include a shape memory actuator surrounding the first and second conductive wires and that has an expanded size and a contracted size and that is sized and arranged such that when the shape memory actuator is in the contracted state the first and second conductive wires contact one another and when the shape memory actuator is in the expanded state the first and second conductive wires do not contact one another.

    摘要： A radiation analysis system comprising a target comprising two marks which are separated from each other, the target being configured to undergo thermal expansion when illuminated with radiation; a position measurement system configured to measure a change in the separation of the marks; and a processor configured to determine a power of the radiation using the measured change in separation of the marks.

    摘要： A resettable sensor assembly includes a body having a axis and defining a cavity therein. The body includes a first plurality of threads disposed about the axis. The assembly includes a housing mated to the body and including at least one electrical contact. The assembly further includes a plate. The assembly also includes an actuator element configured for translating the plate along the axis between a first position in which the plate contacts the at least one electrical contact and a second position in which the plate is spaced apart from the at least one electrical contact. The element is formed from a shape memory alloy that is transitionable between an austenite crystallographic phase and a martensite crystallographic phase in response to a thermal activation signal to thereby translate the plate between the first position and the second position.

    摘要： A wear amount measuring apparatus includes a light source, a light transmission unit, a first and a second irradiation unit, a spectroscope and an analysis unit. The light transmission unit splits a low-coherence light from the light source into a first and a second low-coherence light. The first and the second irradiation units irradiate the first and the second low-coherence light to the component to receive reflected lights from the component. The light transmission unit transmits the reflected lights received by the first irradiation unit and the second irradiation unit to the spectroscope. The spectroscope configured to detect intensity distribution of the reflected lights from the first and the second irradiation unit. The analysis unit calculates a thickness difference between a thickness of the component at the first measuring point and that at the second measuring point by performing Fourier transform on the intensity distribution.

    摘要： An instrumented electric power arrester includes a temperature sensor, wireless transmitter, and a visual over-temperature indicator. A disk shaped module, a replacement varister block, or a dummy block containing the sensor/transmitter is placed between varister blocks inside the arrester housing. A strap-on module is attached to the outside of the arrester housing. The sensor/transmitter utilizes a harvesting power supply that draws electric power for the electronics from the power line protected by the arrester. An ambient temperature sensor may be utilized to enhance accuracy. The temperature sensor/transmitter typically sends arrester monitoring data wirelessly to an RTU or handheld unit located outside the arrester, which relays the monitoring data to an operations control center that scheduled replacement of the arrester based on the monitoring data. A surge counter keeps track of the number of equipment and lightening related temperature surges experienced by the arrester.
