The controller may cause a current to be applied to the TFC heater to generate heat, receive a signal from the ECS indicative of the temperature sensed by the DCR sensor, and determine a composition of the atmosphere or a concentration of the gas based on the signal.

Abstract: A power supply system includes an authentication server. Before receiving power supplied from a power supply coil of a power supply apparatus, an electric vehicle is authenticated by the authentication server. For receiving power supplied from the power supply coil, the electric vehicle gives a power-supply request to request a power-supply controller, which controls the power supply apparatus, to issue a temporary ticket for receiving power supply. The electric vehicle transmits the temporary ticket to the power supply apparatus, and upon determining that the temporary ticket is legitimate, the power supply apparatus executes power supply.

Abstract: If a customer has picked up a product from a display shelf, a display device displays first sales promotion information. In an information providing system, if the customer has not been attracted to the product and has returned the product to the display shelf, the display device displays second sales promotion information, which is different from the first sales promotion information. By displaying the different pieces of sales promotion information using the display device provided near the product, it is possible to promote the product to the customer in two different ways, thereby stimulating the customer's desire to buy the product and reducing loss in opportunities to sell the product.
