  • Publication number: 20220207624
    Abstract: In an electronic payment system according to an example embodiment of the present disclosure, when a terminal device receives, from a user, an order for filling with energy a vehicle to which energy is to be supplied, it determines whether the balance of electronic money is equal to or greater than a predetermined maximum amount of money. When the balance is equal to or greater than the maximum amount of money, the terminal device causes an electronic money management server to secure the maximum amount of money as a credit amount from the balance. After energy is supplied to the vehicle on the basis of the order, the electronic money management server deducts the cost of the energy supply from the credit amount.

  • Publication number: 20080170555
    Abstract: An uplink channel transmission power control method is provided for a CDMA mobile communication system performing one way communication. A base station measures the received level of data transmitted from each mobile terminal at each channel, and generates a transmission power control signal of each uplink traffic channel. The generated transmission power control signals are multiplexed, and the multiplexed common transmission power control signal is transmitted to all mobile terminals by using the common channel shared by the mobile terminals. Each mobile terminal derives the transmission power control signal of the uplink traffic channel used by the terminal, from the received common transmission power control signal, and controls the transmission power of a data packet.

  • Patent number: 6779564
    Abstract: The present invention is directed to method for setting a formed helical compression spring. At the out set, parameters are measured to determine a reaction force axis of a formed helical compression spring. Next, A target reaction force axis of the spring is compared with the reaction force axis determined by the measured parameters to provide an error between the target reaction force axis and the detected reaction force axis. Then, a tilt angle of at least one of the compression plates tilted to an end plane of the spring is provided, in at least one direction on a plane including a coil axis of the spring, on the basis of the error between the target reaction force axis and the detected reaction force axis. Then, at least one of the compression plates is actuated to pressurize the spring, with at least one of the compression plates tilted to the end plane of the spring by the tilt angle.
