Abstract: A vehicle height control apparatus includes an information acquisition device that acquires pressure data on a pressure inside an air tank storing compressed air and obstacle data on an obstacle in front of a vehicle, and a controller that calculates a target vehicle height based on the obstacle data, calculates a required distance required to reach the target vehicle height based on the pressure of the compressed air inside the air tank, and determines a vehicle height control timing, resolving a problem that the vehicle height is unnecessarily quickly controlled compared to the position of the obstacle, or is controlled after the vehicle passes through the obstacle to reduce the ride comfort.

Abstract: The present invention provides a reception apparatus for performing security tunneling and data re-transmission and unidirectionally receiving data from a transmission apparatus and a transmission apparatus for unidirectionally transmitting data to the reception apparatus. When the reception apparatus checks that there is an error in received data, the reception apparatus performs a switching operation or transmits a switching request signal to the transmission apparatus to notify of the error of the received data to the transmission apparatus. When the transmission apparatus has detected the switching, the transmission apparatus re-transmits data, in which an error is generated, to the reception apparatus. The transmission apparatus encrypts the data and transmits the encrypted data to the reception apparatus. According to the present invention, reliability and security of one-unidirectional data communication are improved.

Abstract: The present invention provides a reception apparatus for receiving data from a transmission apparatus in one direction, and a transmission apparatus for transmitting data with regards to the reception apparatus in one direction. If the reception apparatus detects an error in the received data, the reception apparatus informs the transmission apparatus about the error in the received data by switching over one or more communication lines forming a connection with the transmission apparatus. If the transmission apparatus detects a switchover of the one or more communication lines, the transmission apparatus re-transmits the data in which the error occurred to the reception apparatus. According to the present invention, the occurrence of data errors in one-direction data communication is easily recognized, and the reliability of the one-direction data communication is improved.

Abstract: A semiconductor memory apparatus includes a bit line pair electrically connected to a memory cell and a bit line sense amplifier for detecting and amplifying voltage levels of the bit line pair. The semiconductor memory apparatus is configured to perform a test to determine the occurrence of leakage current by deactivating the bit line sense amplifier and applying a test voltage to the bit line pair when the semiconductor memory apparatus is in test mode.

Abstract: A semiconductor memory apparatus with a sub-word line driver is presented which has an increased area margin in the memory core area. The sub-word line driver is configured to operate in response to activation of a main word line and in response to positive and negative sub-word line enable signals. The sub-word line driver includes a pull-up driver and a pull-down driver. The pull-up driver is configured to pull-up drive a first sub-word line to the potential level of the positive sub-word line enable signal in response to the activation of the main word line. The pull-down driver is configured to pull-down drive the first sub-word line in response to the negative sub-word line enable signal.
