Abstract: Power consumption of a seismic sensor is suppressed. The seismic sensor is operated in a power-saving mode and a measuring mode in which the power consumption is larger than that of the power-saving mode. The seismic sensor includes: a measuring part configured to measure an acceleration; an index calculator configured to transition from the power-saving mode to the measuring mode to calculate an index value indicating a size of an earthquake when the acceleration measured with the measuring part exceeds a first threshold; and a threshold adjuster configured to change the first threshold so as to increase the first threshold relative to a predetermined reference value when a tendency of the acceleration measured with the measuring part satisfies a predetermined condition.

Abstract: A recovery device is configured to recover specific material as a dewatering aid from sludge generated in a sewage treatment process. The recovery device includes: a grinder configured to fragment a solid in the sludge to obtain prepared sludge; a separator configured to separate hardly decomposable organic matter and easily decomposable organic matter from the prepared sludge; and an extractor configured to continuously extract hardly decomposable organic matter having specific properties as the dewatering aid from the hardly decomposable organic matter separated by the separator.

Abstract: A sludge dehydration method includes a recovery process of recovering specific material as a dewatering aid from sludge generated in a sewage treatment process and a dewatering process of performing solid-liquid separation on sludge in which the dewatering aid recovered in the recovery process and dewatering target sludge are mixed.

Abstract: A medical system wherein multiple medical devices are connected to a system controller which controls the medical devices via communication lines is arranged such that in the event that trouble occurs, a user operates a maintenance button, which causes the system controller to display multiple trouble items relating to the actions of the medical devices on a display panel, and the user specifies a trouble item matching the currently-occurring trouble from the displayed multiple trouble items, whereby the system controller performs estimation processing for recovering from the specified trouble item and displays countermeasures information for recovering from the trouble item based on the estimation processing, and the user performs processing following the displayed countermeasures information, thereby enabling trouble to be efficiently recovered from.

Abstract: A medical equipment control system consists mainly of a plurality of centralized controllers each of which controls on a centralized basis a plurality of pieces of medical equipment installed in an operating room, and a mobile device capable of communicating with the plurality of centralized controllers. The mobile device is used to determine or record control data based on which the plurality of pieces of medical equipment is controlled. The recorded control data is transmitted to and recorded in the centralized controller in an operating room concerned. Thus, a medical equipment control system capable of controlling medical equipment at low cost on a centralized basis is realized.
