摘要： The present invention provides a contactlessly readable tag with which both a small tag size and long-distance readability can be achieved, a method for manufacturing the contactlessly readable tag, an identification device, and an identification information determination system. In this tag 200, the arrangement pattern of metal parts in a metal pattern layer 202 of this tag 200 is associated with identification information, and when irradiating the tag 200 with electromagnetic waves, the identification information can be read on the basis of the information of the electromagnetic waves reflected by the tag 200, and the metal pattern layer 202 is provided closer to a reading surface side of the tag 200 than a buffer layer 201 having at least a single layer.

摘要： This learning device is provided with: a simulation execution unit that, by using electromagnetic field analysis simulation, determines a reflected wave spectrum obtained when electromagnetic waves are emitted from a reader to an identification target; and a machine learning unit that, by using training data in which the reflected wave spectrum calculated by the simulation execution unit and an attribute thereof are defined as a set, performs a training process on a learning model by machine learning. The simulation execution unit generates a plurality of the reflected wave spectra belonging to the same attribute by variously changing various parameters related to the identification target from reference parameters. The machine learning unit performs a training process on the learning model by machine learning by using, as training data, the plurality of reflected wave spectra obtained for each attribute.

摘要： A chipless RFID tag can be scanned with high accuracy and robustness. A tag reader includes: a processing part configured to output information calculated from an emergent wave having an incident wave, as a radio wave irradiated to a tag (an object to be identified) emerged by way of the tag; and a determining part configured to identify attributes of the tag, using the information.

摘要： A detecting system includes: a sensor (10) that includes an antenna unit (11) formed with a metal pattern, and a back surface reflector (13) that faces the antenna unit (11) via an isolation layer (12); and a reader (20) that transmits electromagnetic waves (Fa) to the sensor (10), receives reflected waves (Fr) from the sensor (10), and compares the reflection characteristics of the sensor (10) detected from the reflected waves (Fr) with the reflection characteristics of the sensor (10) stored in advance, to detect a state change in the sensor (10).

摘要： The objective of the present invention is to provide a device for calculating a gloss value using a gloss value calculating method having an enhanced correlation with an impression of gloss sensed visually by a person. The present invention for achieving this objective relates to a gloss value calculating device. The gloss value calculating device comprises: a peak calculating unit which uses distribution information of brightness or reflection intensity with respect to a light reception angle obtained by measuring reflected light resulting from the reflection of measuring light radiated at an object, to obtain the peak height and spread of the brightness or the reflection intensity in the distribution information; and a gloss value calculating unit which calculates a gloss value represented by a ratio of the peak height to the peak spread.
