Abstract: A water quality measuring system includes a first introduction section for introducing rearing water as a sampling target, and a first adding section which adds an acid to the rearing water introduced by the first introduction section, and a nitrous acid sensor whose measurement target is nitrous acid and which measures the measurement target concentration of the rearing water to which the acid has been added by the first adding section. The water quality measuring system includes a second adding section which adds a base to the rearing water introduced by the first introduction section, and an ammonia sensor whose measurement target is ammonia and which measures the measurement target concentration of the rearing water to which the base has been added by the second adding section.

Abstract: An aquaculture system (Sy) includes mineral sensors (22, 24, 26) for detecting the concentrations of minerals contained in rearing water within a rearing tank (50) for rearing an aquatic organism or the rearing water within a circulation passage (70), and an adjustment section which performs instruction issuance or operation for rendering the concentrations of the minerals contained in the rearing water coincident with their standards when the mineral concentrations detected by the mineral sensors (22, 24, 26) deviate from their standards.

Abstract: In a produce management system (1), a production-base-side apparatus (10) outputs management data generated or input in a process of breeding produce at a production base. A management-base-side apparatus (70) stores or outputs at least one of the management data, a piece of relevant information generated as a result of processing or inspection of the management data, and a piece of certification information generated in response to obtainment of the management data, when the management-base-side apparatus obtains the management data.

Abstract: A data management device configured to manage data stored in a contactless storage medium mounted to an electronic apparatus has a data storage unit that stores a plurality of data units including information of the electronic apparatus, a state detection unit that detects a state of the electronic apparatus, a data selection unit that, by referring to selection rules associating states of the electronic apparatus with types of the data, selects data comprising information conforming with the electronic apparatus under a state detected by the state detection unit from the data storage unit, and a data management unit that stores the data selected by the data selection unit in the contactless storage medium.

Abstract: Embodiments of the invention provide RFID inlay structures that can be written to and read from more than one direction. Embodiments of the invention also include RFID inlay structures constructed such that adjacent inlays doe not touch one another, even when adjacent, underlying object are in close proximity.
