Abstract: A thermoelectric power generation system 20 includes a heat exchanger 1 having double tubes which are an inner tube 1a and an outer tube 1b, and a thermoelectric power generation module 2 mounted between the inner tube and the outer tube. The thermoelectric power generation module generates thermoelectric power using a temperature difference between a medium inside the inner tube and a medium outside the outer tube, and a highly thermal conductive elastic sheet 3a, 3b is mounted between the thermoelectric power generation module and the inner tube and/or the outer tube in close contact therewith.

Abstract: A tubular heat exchanger with a thermoelectric power generation function includes an inner tube 4 in which coolant flows, a thermoelectric power generation module 5 attached to an outer peripheral surface of the inner tube 4, an outer tube 3 attached to an outer peripheral surface of the thermoelectric power generation module 5, and heat collection fins 6 provided on an outer peripheral surface of the outer tube 3. The thermoelectric power generation module 5 generates thermoelectric power using the outer peripheral surface of the inner tube 4 as a low temperature source and an inner peripheral surface of the outer tube 3 as a high temperature source. The inner peripheral surface of the outer tube 3 closely contacts the outer peripheral surface of the thermoelectric power generation module 5.

Abstract: An information processing method that causes a computer to execute a procedure, the procedure includes storing, when first biometric information transmitted from a mobile terminal whose position with respect to the computer satisfy a condition is received, the first biometric information in a memory, specifying, when second biometric information is captured by the computer, first biometric information corresponding to the second biometric information among one or more first biometric information stored in the memory, and transmitting payment information to mobile terminal that is a transmission source of the specified first biometric information.

Abstract: An information processing method that causes a computer to execute a process, the process includes receiving one or more terminal information transmitted from one or more mobile terminal whose position with respect to the computer satisfy a condition, transmitting, when first biometric information is captured by the computer, the first biometric information to the one or more mobile terminal based on the one or more terminal information, specifying, when a collation result of collating between the first biometric information and second biometric information stored in each of the one or more mobile terminal is received from the one or more mobile terminal, a mobile terminal of which the received collation result satisfies a criterion among the one or more mobile terminal, and transmitting settlement information to the specified mobile terminal.

Abstract: A container includes: a sensor configured to output a signal regarding a situation around the container; a memory; and a processor coupled to the memory, the processor being configured to execute a recognition process that includes recognizing the situation around the container in accordance with the signal from the sensor, execute a determination process that includes determining, in accordance with a result of the recognition, a group attribute to which one or more persons around the container belong, execute a registration process that includes registering the group attribute to the memory associatively with the container.

Abstract: A container includes: a touch screen configured to display a first area and a second area, the first area including an image regarding a commodity advertisement, the second area including an operation unit configured to receive a manipulation by a user; and a transmission circuitry configured to transmit a purchase request when the operation unit displayed on the touch screen receives the manipulation, the purchase request including a first identification for the container and a second identification for a commodity displayed on the first area of the touch screen.

Abstract: A display control method includes: accepting registration of a target image that is to be displayed on a display unit in a container and that is associated with location information, by a processor; sending, when acquiring the location information on a container or the display unit in the container and identification information on the container or the display unit in the container, the image registered in accordance with the location information to a destination that is associated with the identification information, by the processor; and displaying the image on the display unit in the container, by the processor.

Abstract: A flight control method that includes: by a processor, referring to a storage section that stores information related to flight control in association with airspace area, and acquiring information related to flight control corresponding to a specified airspace area; and controlling flight of a subject device based on the acquired information related to flight control.

Abstract: A baggage arrangement management method includes acquiring information for identifying a collection place of an arrangement destination from a RFID tag of an arrangement target piece of baggage, acquiring information for identifying a collection place at which baggage is arranged from an RFID tag of the piece of baggage lastly arranged at the collection place, and comparing the two pieces of information to confirm the collection place. Information of identifying each piece of baggage arranged at the collection place is cumulatively recorded in the RFID tags of the subsequent pieces of baggage arranged next to the place.

Abstract: A manufacturer of an article generates a keyword, and electromagnetically writes the keyword into an RFID and prints the keyword on a guarantee card. The RFID tag is then affixed to the article, and the article is packed along with the guarantee card and shipped. When making a sale, a retail store hands over the guarantee card to a customer who buys the article. When the customer wishes to sell the article, a purchasing store reads the keyword written to the RFID tag affixed to the article and asks the customer to furnish the keyword. If the keyword furnished by the customer, by referring to the guarantee card, etc., is identical to the keyword read from the RFID tag, the customer is deemed a genuine owner of the article.

Abstract: A frequency processing circuit has a suppressing circuit for suppressing a lower sideband wave of an input FM signal whose frequency is modulated, a frequency conversion circuit for converting the frequency of an output of the suppressing circuit, and an emphasizing circuit for emphasizing a lower sideband wave of an output of the frequency conversion circuit. The emphasizing circuit emphasizes a share of the amount of the wave suppressed by the suppressing circuit.
