Abstract: A freight transportation system includes a first freight transportation apparatus configured to travel in a first section, a second freight transportation apparatus configured to travel in a second section, a power reception apparatus configured to receive regenerative power from the first freight transportation apparatus that is configured to travel in the first section, a power transmission apparatus configured to transmit the regenerative power to the second freight transportation apparatus that is configured to travel in the second section, and a control apparatus. The control apparatus is configured to perform control so that the second freight transportation apparatus starts traveling from a start point of the second section at a timing when the first freight transportation apparatus starts traveling from a start point of the first section.

Abstract: An information processing device includes a control unit configured to generate power supply permission information that is information permitting power to be supplied to a device electromagnetically connected to power supply equipment, and output the power supply permission information to the power supply equipment.

Abstract: An information processing apparatus includes: an information acquisition interface configured to acquire information related to a behavior of a user; and a controller configured to estimate a product required by the user based on the information related to the behavior of the user, generate information supporting a purchase of the estimated product, and cause an output interface to output the generated information.

Abstract: A product management apparatus includes an information acquisition interface and a controller. The information acquisition interface is configured to acquire, from a terminal apparatus, information related to requests from a user. The controller is configured to apply a purchased tag to a product, based on a purchase request from the user that is acquired using the information acquisition interface, the purchased tag identifying that the product is a purchased product of the user, cause the product to which the purchased tag is applied to be unloaded from a predetermined storage space, based on a receipt request from the user that is acquired using the information acquisition interface; and remove the purchased tag, based on a return request from the user that is acquired using the information acquisition interface.

Abstract: An information processing apparatus includes an information acquisition interface configured to acquire a measurement result from one or more weight sensors configured to measure a weight of a user, and a controller configured to detect an increase in the weight of the user based on the measurement result.

Abstract: An information processing system disclosed includes a controller. When the controller detects that a first user and a second user have been separated to become lost to each other in a specific area, it determines the location of the first user using data that links the first user and the second user and images captured by a plurality of cameras provided in the specific area. Then, the controller executes the processing of providing an entertainment to the first user at the determined location of the first user and providing information about the determined location of the first user to the second user.

Abstract: There is provided a technology that can improve the convenience of users who are reading books. An information processing apparatus has a controller that determines a focus sentence in a subject book that a user is reading. The focus sentence is a sentence on which the user is focusing attention. The controller analyzes what the focus sentence describes and obtains related information relating to what the focus sentence describes. Moreover, the controller executes the processing for causing a user's terminal that the user is using to display the related information.

Abstract: A user terminal of a first user acquires a topic of a predetermined event occurring between the first user and a second user who is another user, detects a behavior, of the first user, on a web performed in relation to the topic, generates web behavior history information that is a history of the behavior, and transmits the web behavior history information of the first user. A server receives the web behavior history information of the first user, and transmits, to a user terminal of the second user, information indicating a degree of interest in the topic or the second user felt by the first user, the information being based on the web behavior history information of the first user.

Abstract: An information processing apparatus disclosed includes a controller configured to execute the processing of obtaining user identification information for identifying a user, obtaining property information indicating a property of the user on the basis of the user identification information, and determining an upper limit number on the basis of the property information. The upper limit number is the number of specific items that the user is allowed to purchase.
