  • 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.

  • Patent number: 8554646
    Abstract: An accounting system under standard costing as absorption costing which identifies a break-even point, performs a process in which, in a break-even chart represented as a standard-costing marginal profit chart for a company or business line departments, a “net carryover manufacturing overhead allocation cost” ? of an inventory and a managed gross profit QM (=Sales Amount X?Sales Absorption Cost) are defined, a managed fixed cost F (=?+Manufacturing Overhead C+General Administrative Cost G) is treated as a fixed cost, and the point of intersection between line segment OB? connecting the origin O (0, 0) and point B? (X, Vs) and horizontal line segment EN? taking the value of the managed fixed cost F is identified as a break-even point (point H2?). Here, Vs is the sum of the managed gross profit QM and a sales manufacturing overhead allocation cost ACX.
