  • Patent number: 10894526
    Abstract: A key unit that locks and unlocks a target by transmitting a signal to a locking and unlocking device, includes: a substrate on which a power supply circuit and a reception circuit that receives a request signal transmitted in a first frequency band from the locking and unlocking device via a reception antenna are mounted; and a housing configured to accommodate the substrate. Among parts associated with the power supply circuit, a part having the highest height from a substrate surface is mounted on a first surface of the substrate. The reception antenna is mounted on a second surface. When the substrate is accommodated in the housing, a distance from a substrate surface of the second surface to an inner surface of the housing is shorter than a distance from the substrate surface of the first surface to the inner surface of the housing.

  • Patent number: 10668896
    Abstract: A car sharing system includes a car sharing device. The car sharing device includes a key function unit and a user authentication function unit. The key function unit allows a device of a vehicle that is shared with multiple people to operate by performing ID verification through a process similar to an electronic key of the vehicle. When the device of the vehicle is operated with a mobile terminal, the user authentication function unit obtains key information from an external device via the mobile terminal and performs authentication of the key information. When authentication of the key information is accomplished and use of the vehicle is within a reservation time, the user authentication function unit validates the key function unit. The key information is generated as information that is permitted only a temporary use.
