  • Patent number: 10195945
    Abstract: A control device is provided for an electric vehicle that generates a braking force corresponding to an opening degree of an accelerator pedal to decelerate the electric vehicle. The control device for the electric vehicle includes a motor configured to generate a driving force or a regenerative braking force of the electric vehicle, a friction braking unit configured to generate a friction braking force, and a controller configured to control at least one of the motor and the friction braking unit corresponding to the opening degree of the accelerator pedal. The controller determines whether all of regenerative electric power generated by the motor is consumed in the electric vehicle when the motor is caused to perform a regenerative braking. The controller causes the motor to perform the regenerative braking when the regenerative electric power is determined to be consumed in the electric vehicle.

  • Patent number: 9492738
    Abstract: A game apparatus includes a CPU, and the CPU sets a weapon to be transmittable according to an instruction by a player. More specifically, a seed is generated from a weapon, and transmittable seed data corresponding to the generated seed is stored in a memory for saved data. When a game apparatus is carried in a sleep state by a player, it makes a communication with another game apparatus to thereby transmit and receive the transmittable seed data with the other game apparatus. Accordingly, the transmittable and receivable seed data, that is, the seeds are exchanged. During the game, the received two seeds are fused to thereby generate a weapon.
