IPC: H02K57/00
Filed: 2001-10-29
Abstract: PURPOSE: A self-generating system is provided to generate an electrical energy over a long period of time without causing an environmental contamination. CONSTITUTION: A self-generating system comprises a power device(10) and a generator device(60). The power device includes a base plate(122), a first magnet(150), a second magnet(130) and a power transmitting component(120). The power transmitting component is mounted on the base plate, and the second magnet is fixed on the power transmitting component in such a manner that the second magnet is electrically driven together with the power transmitting component. When the second magnet passes through the first magnet, magnetic fields of the first magnet and the second magnet interact with each other so as to thereby generate a forward direction force. Thus-generated forward direction force permits the second magnet to be relatively driven with respect to the first magnet. The generator device includes a single induction coil component which is mounted on the first magnet and in the second magnet. The induction coil component generates an induction current when the second magnet and the power transmitting component are sequentially electrically driven, to thereby produce an electrical energy over a long period of time.

Title: Call control method for handoff guarantee of mobile terminal
Inventor: HAN DONG WON
IPC: H04B7/26
Filed: 2001-12-18
Abstract: PURPOSE: A call control method for guaranteeing handoff of a mobile communication terminal is provided to guarantee the same quality of service for a call when the call hands off a current cell into a new cell. CONSTITUTION: When a handoff occurs as a mobile terminal switches a cell, the mobile terminal propose a bandwidth used for the previous call as a request bandwidth to a base station of a cell into which the mobile terminal is to move. If a minimum request bandwidth value can be allocated within the currently reserved bandwidth, the base station allocates it, while if the reserved bandwidth is short, the base station checks whether there is an available bandwidth including a non-reserved bandwidth(S201). If the minimum request bandwidth value can not be allocated within the available bandwidth, the base station puts call be on standby in a handoff queue(S207). If the requested bandwidth is allowable, the base station checks whether there is an empty queue in the handoff queue(S202). If there is an empty queue, the base station accepts the handoff(S203). The call on standby in the handoff queue is processed in an FIFO(First In First Out) manner(S208). If the call on standby in the handoff queue is subjected to a service, the base station checks whether queuing delay time exceeds a maximum allowable handoff termination time(S209). If the queuing delay time exceeds the base station cuts off a call processing(S210). In allocating a bandwidth for the handoff-accepted call, a minimum value of a maximum request bandwidth value and a value obtained by adding a reserved bandwidth and a non-reserved bandwidth of the cell is allocated(S204). If the handoff in service is a guarantee type traffic, a bandwidth reservation is requested from a new adjacent cell according to the handoff as occurred(S205). Releasing of the bandwidth which has been reserved for the adjacent cell is requested from the previous base station of the handoff call(S206).
