Abstract: A display interface system includes a display transmitter and a display receiver. The display transmitter transmits a control pattern having image type information about a type of an image to be displayed and selectively transmits image data according to the type of the image to be displayed. The display receiver receives the control pattern and selectively receives the image data based upon the image type information, reducing power consumption.

Abstract: A short pulse rejection circuit may include an edge detector, a filter circuit, a comparison circuit, and a gating circuit. The edge detector may delay an input signal to generate a delayed input signal, and detect an edge of the input signal to generate an edge detection signal. The filter circuit may perform a low pass filtering on the edge detection signal to generate a first signal. The comparison circuit may compare the first signal with a reference voltage. The gating circuit may gate the delayed input signal based on an output signal of the comparison circuit. Therefore, the short pulse rejection circuit may have a sufficient setup/hold time margin of a flip-flop, and may sample an input signal even when a state of the input signal does not change during an initial operation.

Abstract: A data transmission circuit is disclosed. The transmission circuit includes a serial clock generator, a serializer and a transmission clock generator. The serial clock generator generates a serial clock. The serializer serializes N-bit parallel data to N-bit serial data in synchronization with the serial clock. The transmission clock generator receives the serial clock to generate a transmission clock that has a same delay as the N-bit serial data, and the data transmission circuit simultaneously transmits the N-bit serial data and the serial clock.

Abstract: A voltage-drop measuring circuit is capable of measuring a voltage-drop of a power supply voltage caused by a resistance component of a power line. The voltage-drop measuring circuit includes a sensing circuit and a voltage-drop detecting circuit. The sensing circuit includes a sensor configured to generate a sensing voltage received by the sensor from a power pad through a power line between the sensor and the power pad. The voltage-drop detecting circuit is arranged in a neighborhood of a power pad, and is configured to generate a reference voltage, compare the sensing voltage with the reference voltage to detect the voltage-drop, and generate a detecting signal in accordance with the voltage-drop.

Abstract: Data transmission between transmitting/receiving nodes in a bus system may be controlled based on an error check of received data. When an error in the received data is detected, the transmitting node may cease data transmission, and other nodes, which may not have detected the error, may be notified of the detected error.

Abstract: The present invention relates to a process for preparing pravastatin sodium. More specifically, in the process for preparing pravastatin sodium by adding a precursor of the pravastatin to a microorganism-culturing medium to obtain pravastatin sodium, the precursor of the pravastatin is added to a culture medium that is culturing Streptomyces carbophilus KBT229 (KCCM-10317), which is obtained by UV-mutating a Streptomyces carbophilus FERM BP-1145, and cultured to obtain the pravastatin sodium with high density and high efficiency.
