The present invention relates to a freshness guide method and a freshness guide system capable of providing guidance with respect to the freshness of food sealed in a packaging container. The freshness guide method and the freshness guide system according to the present invention can accurately provide a user with freshness information regarding food by using IoT, RFID, big data, and artificial intelligence (AI) technologies leading the 4th industrial revolution.

A reading apparatus includes a communication unit, a scanner, and a processor. The communication unit communicates with a wireless tag provided on paper. The scanner scans the paper. The processor acquires data from the wireless tag through the communication unit, acquires an image from the paper by using the scanner, and generates a file in which the data is embedded in the image as hidden characters.

A cosmetic dispenser includes a communication unit, a control unit for acquiring at least one of user information and environment information through the communication unit and acquiring a cosmetic dispensing method based on at least one of the user information and the environment information, and a cosmetic dispensing unit having a plurality of cartridges for containing cosmetics and a discharge unit for discharging the cosmetics contained in the plurality of cartridges. The control unit receives input information in which an amount of cosmetics to be provided is selected by either a number of times of use or a period of use. The cosmetic dispensing unit dispenses each of the cosmetics contained in the plurality of cartridges in an amount corresponding to the number of times of use or the period of use selected according to the input information.

A barcode reader configured to be supported by a workstation and having a housing with a window. A multi-axis radio-frequency identification antenna assembly is positioned within the housing of the barcode reader and includes first, second, and third antennas. The first antenna is configured to emit a radiation pattern oriented in a first direction, the second antenna is configured to emit a radiation pattern oriented in a second direction, substantially orthogonal to the first direction, and the third antenna is configured to emit a radiation pattern oriented in a third direction, substantially orthogonal to the first direction and the second direction.

A game token tray system includes a game token tray having a dual tray structure in which a game token is stored. The game token tray system includes a double tray including a lower tray and an upper tray stacked on the lower tray to store a game token provided with an RF tag in which tag information is stored, a camera that acquires tray image data by imaging the game token stored in the upper tray, an RFID reading device that reads the tag information from the RF tag of the game token stored in the lower tray, and a game recording device that records the tray image data and/or an image analysis result of the tray image data about the game token stored in the upper tray and records the tag information read by the RFID reading device about the game token stored in the upper tray.

A pallet tracking system for tracking a plurality of uniquely identified pallets is provided. The pallet tracking system includes a non-transitory storage device and a tracking circuit. The non-transitory storage device is configured to maintain a pallet database of data concerning the pallets. The data concerning each pallet is accessible by the unique identifier of the pallet and includes a material composition of the pallet. The tracking circuit is configured to receive the unique identifier of one of the pallets from the one of the pallets using a scanning device, retrieve the material composition of the one of the pallets from the pallet database using the received unique identifier, and return the retrieved material composition in response to a request. A pallet sharing system for sharing the pallets with a plurality of custodians using this pallet tracking system is also provided.

A light emitting apparatus includes a light source, and a processor configured to perform control to cause the light source to blink in a blink pattern corresponding to output information including identification information unique to the light emitting apparatus, and configured to, when causing the light source to blink by repeating the blink pattern, change a time interval between the blink patterns.

A code reading device for the parallel reading of a plurality of codes on a plurality of objects arranged next to one another is provided that has a camera unit having at least one camera head for recording an image of the objects, a control and evaluation unit that is configured to localize code zones of the codes in the image and to read the code information of the codes, and a display unit to present the image and to mark the read codes and/or objects having read codes, Here a hand reading unit for reading codes is provided to subsequently read codes not read by means of the camera unit and to transfer the subsequently read code information to the control and evaluation unit.

A light emitting apparatus includes a light source, and a processor configured to perform control to cause the light source to blink in a blink pattern corresponding to output information including identification information unique to the light emitting apparatus, and configured to, when causing the light source to blink by repeating the blink pattern, change a time interval between the blink patterns.

An information processing apparatus includes a table with an embedded display device that has a surface on which an object with a wireless tag can be placed. An antenna unit is configured to move along a predetermined path and to transmit an interrogation wave for reading information from wireless tags. The antenna unit receives a response wave from wireless tags at different positions on the predetermined path. A controller is configured to: calculate changes in phase difference between the interrogation wave and the response wave received at the different positions; determine a location of a wireless tag on the surface of the embedded display device using the calculated changes in the phase difference; and then control the embedded display device to indicate the determined location.
