Abstract: The present invention provides a sensing device and a loading rate estimation system that has a high durability, enables stable sensing of the opening angle of a load compartment door, and makes it possible to minimize a decrease in the freedom of design around the load compartment door. In the present invention, a sensing device has: a recognition unit for acquiring an image obtained by imaging a part of the load compartment door in an open state, and recognising a door-corresponding portion, which is a portion corresponding to the load compartment door in the image; and a calculation unit for calculating, as the opening angle of the load compartment door, the angle between the door-corresponding portion and a reference portion.

Abstract: A platooning assistance device and a program with which it is possible to distribute the effect of platooning, and make payment. The platooning assistance device lets each of a plurality of vehicles forming a platoon have: a transaction data generation unit that generates platoon identification information identifying the platoon, vehicle identification information identifying the vehicle, and fuel consumption of the vehicle during platooning as transaction data; and a communication unit that transmits the generated transaction data to a network, and receives, from the network, data is the transaction data of each of the plurality of vehicles, and approved by a blockchain function. Any one of the plurality of vehicles has: a storage unit that stores smart contract data having a programmed, process for distributing the effect of platooning and making payment; and an execution unit that executes the process, on the basis of the approved data, in the blockchain.

Abstract: A wireless communications terminal prevents radio interferences caused by other wireless communications concurrent with a contactless communication. A wireless communications terminal receives, in a contactless communication, a command from a reader/writer via a second wireless communications section, and analyzes the received command. The wireless communications terminal controls a wireless communications control section to deactivate or temporarily deactivate the function of a first wireless communications section depending on the analysis of the command. After the function of the first wireless communications section is deactivated or temporarily deactivated, the wireless communications terminal accesses a memory area of an IC card microcomputer system as specified by the command to perform a contactless communication.

Abstract: A contactless integrated circuit (IC) card (11) is comprised of the following: a first antenna coil (102) and a second antenna coil (103) for generating an electromotive force by receiving electromagnetic waves from a reader/writer; a first electromotive force measuring unit (311) and a second electromotive force measuring unit (312) for respectively measuring the electromotive force generated by each of the antenna coils; an electromotive force comparing unit (313) for comparing the characteristics of the electromotive forces which are respectively generated by the respective antenna coils and then measured; and an application selecting/executing unit (215) for selecting one application from a program storing unit (216) based on the comparison made by the electromotive force comparing unit (313) and executing the selected application.

Abstract: The present invention provides a wireless communications terminal capable of preventing radio interferences from being caused by other wireless communications concurrent with a contactless communications. A wireless communications terminal (101) receives, in a contactless communications, a command from a reader/writer (105) via a second wireless communications section (209), and analyzes the received command. The wireless communications terminal (101) controls a wireless communications control section (210) to deactivate or temporarily deactivate the function of a first wireless communications section (208) depending on the analysis of the command. After the function of the first wireless communications section (208) is deactivated or temporarily deactivated, the wireless communications terminal (101) accesses a memory area of an IC card microcomputer system (300) as specified by the command to perform a contactless communications.
