    Abstract: Disclosed herein is a hot plugging device for optical transceiver modules. The hot plugging device comprises a module housing, latching grooves extended from prescribed positions of both sides of the module housing to one end of the module housing, respectively, sliding members extended in the longitudinal direction of the module housing and linearly movably accommodated in the latching grooves, respectively, and a rotating member rotatably attached to one end of the module housing for engaging ends of the sliding members with corresponding ends of the latching grooves, respectively, while the rotating member is placed at a prescribed angle to the longitudinal direction of the module housing. With the hot plugging device of the present invention, a locking unit of the module housing is easily released, and the release of the locking unit is maintained, whereby the module housing is easily separated from a cage. Also, a working space necessary to separate the module housing from the cage is reduced, whereby many more optical transceiver modules can be mounted. Furthermore, only latching pieces are deformed when the module housing is separated from the cage. Consequently, the present invention has an effect of preventing permanent deformation of the module housing or the cage or damage to the module housing or the cage.

    Abstract: In a channel equalizer applicable to a digital television receiver, a forward filter and a backward filter perform filtering to an input signal and a predetermined signal. A Viterbi decoder corrects errors during a transmission procedure in a blind mode. A training symbol storing block stores training symbols. An output signal of the Viterbi decoder and symbols are provided to the backward filter in accordance with a blind mode or a training mode. A Kalman gain is calculated in a Kalman gain calculating block and an error signal is calculated by comparing an equalized signal, symbols, and the output signal of the Viterbi decoder with one another. A tap coefficient is updated by using the calculated error signal and the Kalman gain.

    Abstract: A tablet monitor includes a monitor main body having a connector combining part and a handle accommodating part, a handle foldably accommodated in the handle accommodating part of the monitor main body, and a supporting stand connected to a rear of the monitor main body, and including a connector connected to a connector combining part of the monitor main body. The tablet monitor also includes a first connector having two parts, each provided at the handle and the supporting stand, and each having a shape to correspond to each other to be detachably connected to each other, and a second connector having two parts, each provided at the monitor main body and at the supporting stand, and each having a shape to correspond to each other to be detachably connected to each other. Thus, the monitor main body and the supporting stand may be simply and firmly connected to each other, so that the tablet monitor is used with more convenience. Further, at the same time, when the monitor main body and the supporting stand are connected to each other, the handle may be connected to the monitor main body.
