  • Patent number: 7319978
    Abstract: The present invention relates to a Net shopping method for performing Net shopping through the Internet with a portable terminal. The user freely makes product selections (Net shopping) at any time and place using a portable terminal 2. When the user proposes to conduct a transaction, transaction proposal information, payee information, and the amount of money are automatically sent from the Net shopping site to the portable terminal 2 and stored in the internal memory 22. Next, the user takes the portable terminal 2 to the automatic payment transfer device 4, connects the portable terminal to the payment transfer device 4, and transfers the internal data to the payment transfer device 4. The user can perform payment transfer operations with the payment transfer device 4 based on the order acceptance data. Thus the payment transfer process can be performed safely and with a simple operation.

  • Patent number: 7095711
    Abstract: A communication method for a radio LAN system provides communication at a first transmission rate. In the method, a first signal of the first transmission rate is time-divisionally distributed into n?1 second signals (n=3, 4, . . . ). The n?1 second signals are respectively converted into n?1 third signals of a second transmission rate less than the first transmission rate. The n?1 third signals of the second transmission rate are also transmitted through radio transmission paths between n?1 radio base stations and a terminal station connected to at least one terminal unit.

  • Patent number: 7075664
    Abstract: This invention discloses an image forming apparatus having an image reading function that can correct the density even when an image is formed based on data acquired from an apparatus other than an image reading apparatus, and a control method therefor. A printer controller (2103) includes a PG unit (3112) for generating a pattern having a predetermined density. The pattern is transmitted to an engine controller (2002) via an output I/F to obtain a print result. Correction data representing the difference between a result obtained by reading the print result and a predetermined characteristic is received from a reader controller via a serial communication controller (3111). The correction data is stored in a data correction unit (3108) and used for printing data subsequently received via an input I/F.
