    摘要： In a medical X-ray CT apparatus, a rotary portion is rotated, and a wind is produced inside the apparatus by the rotation of the rotary portion. An expanded cover portion is forced to vibrate by the wind, and noise is produced. The expanded cover portion is provided with at least one curved member including both ends. The curved member is arranged to extend along a virtual projection line obtained by geometrically projecting a virtual straight line connecting, to each other, the two ends fixed to an outer peripheral edge of an opening of the expanded cover portion onto a surface of the expanded cover portion, and the vibration of the expanded cover portion is reduced.

    摘要： Moving information of an object is input, and first sound information around the object is input. A motion status of the object is recognized based on the moving information. Second sound information is selectively extracted from the first sound information, based on the motion status. A first feature quantity is extracted from the second sound information. A plurality of models is stored in a memory. Each model has a second feature quantity and a corresponding specified context. The second feature quantity is previously extracted by the second extraction unit before the first feature quantity is extracted. A present context of the object is decided based on the specified context corresponding to the second feature quantity most similar to the first feature quantity. The present context of the object is output.

    摘要： According to one embodiment, a monitoring apparatus includes an acquisition unit, an analysis unit, a calculation unit, a storage, a determination unit. The acquisition unit acquires an environmental sound. The analysis unit performs frequency analysis to extract characteristic frequency components. The calculation unit calculates first values of metrics. The storage stores contour data generated by second values of the metrics. The determination unit determines whether or not there is a first measurement point in which a first value and a second value match, if there is no first measurement point or the change is not less than the threshold value, determines that the machines is abnormal.
