  • Patent number: 10172336
    Abstract: A fishing reel including: a main body mounted on a fishing rod; a spool for allowing a fishing line to be wound or unwound, the spool being installed on the main body so as to be rotatable; and a fishing wheel for rotating the spool, the fishing wheel being connected to a spool shaft gearshift which induces rotation of the spool. The fishing wheel is connected to the spool shaft gearshift via angle variation means, and a connection angle between the wheel and the gearshift varies using the angle variation means to reduce strain applied on a user's wrist while rotating the spool.
    Type: Grant

  • Patent number: 9363789
    Abstract: An apparatus and method for dynamically allocating a multicast path in a broadband wireless access system are provided. A method for an operation of a server providing a multicast service through a wireless access network includes determining to establish multicast paths for a first Base Station (BS) and at least one neighboring BS of the first BS when a terminal receiving the multicast service enters a network through the first BS, and transmitting a control station a message of instructing to establish the multicast path for a BS not holding the multicast path among the first BS and the at least one neighboring BS of the first BS.

  • Patent number: 8918132
    Abstract: An apparatus and a method for setting a group communication session using a wireless access system are provided. The method includes transmitting, at a transmission side client, a message requesting start/end of group communication to a control Push To Talk (PTT) server, transmitting, at the control PTT server, a session set/end message including a sequence number to a participating PTT server, multicasting, at the participating PTT server, a connect/disconnect request message N times for at least one reception side client, and setting/releasing, at the at least one reception side client, a session for the group communication.
