    Abstract: An AI control device, which identifies individual users from a plurality of users to receive input data, and is connectable to a server device that generates a trained model based on input data for each user, includes a control unit, and a communication unit connected to the server device. The control unit acquires input data, associates acquired input data and identifying information used to identify the user of the AI control device, and sends the data and information to the server device via the communication unit. The control unit uses the sent acquired input data to execute a trained model that is generated separately from trained models of other users by the server device, and that learns characteristics of acquired input data and detects input data having the same characteristics from unknown input data.

    Abstract: This channel simulation device is provided with a memory for storing a distance calculation parameter and reception strength calculation parameter, and a processor for estimating desired-wave reception strength and interfering-wave reception strength on the basis of the distance calculation parameter and the reception strength calculation parameter. The desired-wave reception strength refers, for each set of two areas selected from a plurality of areas, to reception strength when a transmission signal transmitted from the wireless microphone of one area is received by a receiver in the one area. The interfering-wave reception strength refers to reception strength when a transmission signal transmitted from the wireless microphone of the other area is received by the receiver in the one area.

    Abstract: A quantification method includes a calibration curve preparing step to measure a standard solution, which has been prepared by adding sodium ions so that a sodium ion content of the standard solution is equaled to a sodium ion content of a sample to be measured with a method employing a reaction that activates a limulus reagent and/or a biochemical luminescent reaction caused by ATP, luciferin, and luciferase, and to prepare a calibration curve that represents a relation between a measurement value and an amount of a component to be measured; a sample measuring step to measure the sample to be measured with a method being the same as that used in the calibration curve preparing step; and a quantifying step to find, by using the calibration curve, an amount of the component to be measured in the sample to be measured from a measurement value in the sample measuring step.
