Abstract: A dialysis apparatus has a replenisher passage selectively connectable to an arterial side passage (pre-replenishment) or a venous side passage (post-replenishment) in a blood circuit. A supply side pressure sensor measures a pressure of a dialysate supply passage and a collection side pressure sensor measures a pressure of a dialysate collection passage. The connection passages each have one end communicating with the arterial side passage or the venous side passage of the blood circuit and another end connected to the dialysate collection passage. It is determined whether the replenisher passage is connected to the arterial side passage or the venous side passage, based on a differential pressure of pressures measured by the supply side pressure sensor and the collection side pressure sensor, in a state where a dialysate pump (liquid delivery device) causes dialysate to flow into the blood circuit from the replenisher passage.

Abstract: A dialysis apparatus has a connection channel that communicatively connects a dialysate circuit and a blood circuit, and circulates dialysate from the dialysate circuit to the blood circuit via the connection channel during a priming operation. A blood pump has a tube attachment device that switches from an unattached state in which a tube is positioned outside a housing and permits liquid to circulate thereinside, to an attached state in which the tube is in the housing and a rotor compresses the tube. At the time of priming, the liquid feeding pump feeds dialysate from the dialysate circuit to the blood circuit via the connection channel. With the blood pump being in the unattached state, the dialysate is circulated past the blood pump, and then, with the blood pump in the attached state, the dialysate is circulated in a direction opposite to the blood pump.

Abstract: A client device accepts event information for which a people flow prediction is to be performed from a user and the client device inputs the accepted event information to a people flow prediction device. The people flow prediction device outputs a result of people flow prediction responsive to the input event information to the client device and the client device displays the result of people flow prediction to the user. The people flow prediction device performs a people flow prediction by temporally and spatially allocating an event attendance which has been input from the client device to pathways, each connecting a transport facility at which a people flow originates and an event site. Consequently, it is possible to predict a flow of people who attend an event or the like, the people flow differing from that in an ordinary situation, without need to input real-time data.

Abstract: A reference range identifying device acquires and records, at a predetermined time interval, a measuring result of a load and exhaust temperature of an engine. The device identifies, based on combinations of the load and exhaust temperature recorded at multiple points of time, for each load zone, for example a 95% confidence interval of a distribution of exhaust temperatures as a reference range. Subsequently, the device calculates an approximate curve for lower limits and upper limits of reference ranges identified for the load zones. The device identifies a range sandwiched by the calculated two approximate curves as a reference range that changes in accordance with a load. The device, upon detecting that a current load and exhaust temperature of the engine is not included in the reference range, notifies the detected fact to a user.

Abstract: A reference range identifying device acquires and records, at a predetermined time interval, a measuring result of a load and exhaust temperature of an engine. The device identifies, based on combinations of the load and exhaust temperature recorded at multiple points of time, for each load zone, for example a 95% confidence interval of a distribution of exhaust temperatures as a reference range. Subsequently, the device calculates an approximate curve for lower limits and upper limits of reference ranges identified for the load zones. The device identifies a range sandwiched by the calculated two approximate curves as a reference range that changes in accordance with a load. The device, upon detecting that a current load and exhaust temperature of the engine is not included in the reference range, notifies the detected fact to a user.
