Abstract: A personal information system includes an acquisition unit, a storage unit, a personal storage unit, and a control unit. The acquisition unit is configured to identify an occupant of a vehicle and acquire a status of the occupant. The storage unit stores usage history information of a vehicle device and state information of the occupant acquired by the acquisition unit. The personal storage unit is set for each occupant and is configured to retrieve, as personal information, the usage history information and the state information from the storage unit for each occupant and sequentially store the usage history information and the state information. The control unit is configured to perform control that utilizes the personal information stored in the personal storage unit to provide a service, in a manner matching characteristics of each occupant when operating the vehicle device.

Abstract: A device for mobile object, which is usable in a mobile object, includes an occupant information specifying unit and a request estimation unit. The occupant information specifying unit specifies an occupant information record for each of multiple occupants existing in the mobile object by distinguishing the multiple occupants from one another. The multiple occupants are detected by a sensor of the mobile object. The request estimation unit estimates a request of one of the multiple occupants corresponding to a combination of the occupant information records of the multiple occupants based on the occupant information records of the multiple occupants specified by the occupant information specifying unit.

Abstract: In a technique for controlling a first vehicle, display information and position specifying information are received from a second vehicle different from the first vehicle via inter-vehicle communications. The display information is information for display and independently set for the second vehicle in the second vehicle. The position specifying information is information for specifying a position of the second vehicle. The position of the second vehicle relative to the first vehicle is specified based on the position specifying information. Display on a display device is controlled to superimpose information indicated by the display information on the position of the second vehicle in a landscape in front of the first vehicle based on the position of the second vehicle and the display information.

Abstract: A human machine interface is configured to select an information display destination from among a plurality of display areas. The HCU acquires a sight line direction of a driver based on an image of an in-vehicle camera. The HCU displays, upon detecting a hop-off action of the driver based on an output signal of an in-vehicle sensor in a situation in which an attention target event such as a puddle, a step, other vehicle or the like exists on a road surface near a door of a driver's seat, in the display area corresponding to the driver's sight line direction, text or an image practically indicating (a) a content of an attention target event or (b) how to deal with a situation.

Abstract: Provided is a fluoropolymer comprising tetrafluoroethylene unit (1) and a monomer unit (2) derived from a perfluoroalkadlene represented by formula (2): CF2?CF(CF2)nCF?CF2 where n represents an integer of 2 to 10, wherein a content of tetrafluoroethylene unit (1) is 98.0 to 99.999 mol % or more based on total monomer units constituting the fluoropolymer, and a content of the monomer unit (2) is 0.001 to 2.0 mol % based on total monomer units constituting the fluoropolymer.
