Abstract: A bearing condition monitoring device is a bearing condition monitoring device for monitoring a condition of a thrust bearing for holding a rotational shaft in a thrust direction. The bearing condition monitoring device includes a first temperature sensor for measuring a temperature of the thrust bearing, and an arithmetic device for counting a frequency at which an evaluation index of a thrust load on the basis of a measurement value by the first temperature sensor exceeds an allowable value, and for outputting an abnormality in the condition of the thrust bearing if the counted frequency exceeds a threshold. The arithmetic device may count, as the frequency, only a case where a state in which the thrust load exceeds an upper limit load continues for not less than a predetermined time.

Abstract: An example enclosure includes a base, a plurality of walls extending from the base, and a top disposed opposite the base and connected to at least one of the plurality of walls. The at least one wall includes a light assembly configured to illuminate an interior space of the enclosure at least partly defined by the base and the plurality of walls. The top is moveable toward the base to transition the enclosure from an expanded state to a collapsed state. Additionally, the at least one wall includes a first panel and a second panel movable relative to the first panel. Further, the first and second panels extend substantially parallel to the base when the enclosure is in the collapsed state.
