  • Patent number: 10399623
    Abstract: A bike having an energy recovery device includes a driving wheel that is coupled to a rear wheel driving shaft pulley of the bike and rotates with the rear wheel of the bike. When a wire is pulled by the bike rider, an outer peripheral surface of a rotating wheel contacts an outer peripheral surface of the driving wheel and rotates together by means of friction with the driving wheel. When the wire pulling force is released, contact with the driving wheel is released. A piston moves in the forward/backward direction inside a cylinder of a compressor. During operation, air is compressed by the movement of the piston, exits through an exhaust opening formed on the rear portion of the cylinder, and is stored in an air tank through an air hose.

  • Publication number: 20060117186
    Abstract: An entrance and exit management system allows a passenger having a reservation ticket to instantly get into an airplane by automatically ascertaining a reservation state of the passenger. The entrance and exit management system has a portable electronic identification card storing recognition codes of a person having the portable electronic identification card and making a communication with an external device through a Bluetooth communication module and a contact-type communication port or a wired communication port, a plurality of communication modules installed in an entrance region while forming a predetermined interval therebetween so as to communicate with the Bluetooth module and either communication port, a terminal for checking a personal identity, and an entrance and exit management server receiving the recognition codes to compare them with pre-registered information.

  • Publication number: 20050182674
    Abstract: A charge settlement system is capable of settling a charge, even during movement, without access to any card-inquiry terminal such as a magnetic credit card. The system is relatively inexpensive to construct and includes a transaction terminal and a portable wireless settlement device. When the transaction terminal requests a payment to the portable wireless settlement device via a communication network, the portable wireless settlement device accesses a server via a wireless communication network for settlement. The portable wireless settlement device includes wireless communication with a transaction terminal; a button section for payment and receipt; a key-entering section; a display device for displaying various kinds of information; and a controller having various types of data stored therein.
