The present invention relates to a system and an apparatus for synchronization between heterogeneous periodic clock domains, a synchronization failure detecting circuit, and a data receiving method. The synchronization system between heterogeneous periodic clock domains including a sender and a receiver operated according to heterogeneous periodic first clock and second clock, respectively, includes: a sender that outputs a prediction clock obtained by delaying the first clock for a first time; and a receiver that predicts success and failure of synchronization between the first clock and the second clock by using the prediction clock and selectively delays the second clock for a second time according to the predicted results to synchronize the second clock with the first clock.

A digital differential signal transmitter circuit for a low supply voltage. A phase correction circuit for correcting digital signals transmitted through two signal paths in such a way as to have a phase relationship of differential signals and duty cycle correction circuits for correcting the digital signals in such a way as to maintain signal integrity in spite of changes in process, supply voltage and temperature are installed on the two signal paths so that the distortion of digital differential signals is compensated for. Power consumption at a final output section of the transmitter circuit is reduced. Impedances of the transmitter circuit and transmission lines are matched so that the transmitter circuit can operate insensitively with respect to operation circumstances.

The present invention provides a sensory signal output apparatus wherein a coil is disposed in the gap between a magnet/top plate and a yoke, and a portion elastically supported in the free space vibrates in reaction to the magnetic flux generated in the gap in accordance with the direction of the alternating current signal applied to the coil to generate sound and/or vibration, wherein the yoke has a groove formed at a side other than that with the magnet, and the groove has a diameter smaller than that of the magnet, and an inner edge portion with a magnetic fluid. The sensory signal output apparatus of the present invention improves the position retaining force of the magnetic fluid and reduces the deformation of the magnetic fluid, as the magnetic fluid is formed in the edge of the groove of the yoke corresponding to the edge portion of the magnet which has a relatively bigger magnetic force and magnetic field than the plane portion of the magnet. Further, as the magnetic fluid is formed in the edge of the groove such that the magnetic fluid is present at both sides (the horizontal side and the vertical side) extending from the edge, the magnetic fluid at the horizontal side serves to relieve impact caused by a collision against peripheral elements during vibration, and the magnetic fluid at the vertical side corrects center deviation during vibration.

A power amplification apparatus includes a first amplifier turned on at a preset low input power; and a second amplifier connected in parallel with the first amplifier and turned off at a low input power due to a relatively low bias current. Output capacitors of the first amplifier and the second amplifier are compensated for by inductors or microstrip lines of dc power supply paths. An output matching circuit of the first amplifier includes a λ/4 transformer. An output matching circuit of the second amplifier has the phase of 0°. Input matching circuits of the first amplifier and the second amplifier include delay compensation circuits. The output matching circuit of the first amplifier, the output matching circuit of the second amplifier, and a final output matching circuit have the same impedance transformation rates.

The present invention relates to a quasi-orthogonal space-time block coding system and method. The system does not become particularly complicated since the encoding rate is given as 1 and it is possible to decode the encoded signal by using a simple linear algorithm, and system performance is increased since there is no interference component of an adjacent signal in the estimated signal.

A user operating the game machine and playing the game can easily transfer the intention of a necessary order or the like to a waiter/waitress, a main counter or the like, without leaving the game machine. Further, the user can check the total input amount for the total of games, the total payout amount, the win percentage per each game, the accumulated win percentage in the total of games. Further, the user can play the game while confirming the information provided in the language selected by the user in real-time, relatively at a glance. Consequently, the game machine is capable of increasing the fun of the game and preventing the user from going beyond a predetermined limit of spending money by being excessively emotionally linked to the game.

An iterative reception method and iterative receiver in a mobile communication system are provided. In order to remove inter-cell interference of a signal that is iteratively received in a multi-cell environment, a soft determination value of different cells excluding a specific cell is re-spread to be used. In addition, in order to improve reception performance of the iterative receiver that performs the interference removal by using the soft determination value, channel estimation is iteratively performed on the iteratively received signal by using a soft determination value of a previous order of the specific cell to update a channel estimation value. Accordingly, it is possible to reduce complexity of implementation and effectively remove the inter-cell interference by using the soft determination value.
