  • Publication number: 20160079508
    Abstract: The present invention provides a thermoelectric generator module including a set of module unit bodies disposed between a hot source and a cold source to serve as fundamental structures for performing thermoelectric power generation and a method of manufacturing the thermoelectric generator module. Each of the module unit bodies comprises: a first electrodes disposed at one of the hot source and the cold source; a second electrode disposed at the other of the hot source and the cold source so as to be spaced apart from the first electrodes; a first nanowire configured to interconnect the first electrode and the second electrode and composed of an n-type or p-type semiconductor; and a second nanowire.

  • Patent number: 8275076
    Abstract: Provided are a receiver and a method for detecting a signal in a multiple antenna system. The receiver includes a filter coefficient calculator and a signal detector. After separating a first signal portion and a second signal portion, the filter coefficient calculator calculates an MMSE filter coefficient using a Matrix Inversion Lemma such that an inverse matrix of the first signal portion has a predetermined constant value regardless of a repetition signal detection process. The signal detector detects a relevant transmission signal from an interference-removed reception signal using the MMSE filter coefficient.

  • Publication number: 20120205922
    Abstract: Disclosed herein is a locking device of a hinged door. The locking device of the hinged door according to the present invention comprises a trapping part and a fixing part selectively mounted on the hinged door and a door frame and slidly trapped mutually to open the hinged door only at regular intervals. The fixing part comprises a bracket and a clamp rotatably coupled to the bracket. A clamp is partly moved up and down by coupling a trapping means to a keyway connected to a hinge of the bracket. The clamp is supported toward upper parts to maintain a trapping state of the trapping means at the keyway and then limiting a rotation of the clamp. If the trapping means leaves the keyway by a pressure of the hinge of the bracket, the clamp is rotated at the bracket.

  • Patent number: 8170144
    Abstract: A distributed translator and an operation method of the distributed translator are proposed. The distributed translator includes: a demodulator demodulating a received signal to extract a transport stream and synchronization information from the received signal; a modulator generating an output frame based on the synchronization information to modulate the output frame; and a transmitter transmitting the modulated output frame according to a transmission timing.

  • Patent number: 7072644
    Abstract: The present invention relates to a method for providing an arbitrary sound chosen by a subscriber instead of a conventional RBT, more particularly, to a method for providing a caller with an arbitrary sound chosen by the caller instead of an RBT in case that a called is not a subscriber of a called-based RBT replacement service. The present method comprises: a first step, conducted by an exchanger when a call is received from a terminal, of requesting a first trunk connection to other telephone communication network while requesting a second trunk connection to a sound providing means if it is confirmed that the calling terminal has subscribed to RBT replacement service and the called terminal is a subscriber of said other telephone communication network; and a second step, conducted by the sound providing means, of providing the calling terminal with an RBT-replacing sound set for the calling terminal through the exchanger.
