Abstract: Disclosed is a hydraulic pilot valve which is provided with an orifice so as to reduce vibration of a valve and minimize impact applied to a valve even when a valve is suddenly operated. At least some of hydraulic oil supplied to a supply chamber flows to a valve chamber or a central pipeline through a damping unit according to elevation of a spool.

Abstract: Embodiments are directed towards a notification message system arranged to generate notification messages. Responsible resources may be determined based on the notification messages and a schedule. A plurality of message providers that have a provider profiles may be determined based on the responsible resources and a region. A message provider from the plurality of message providers may be determined based on its provider profile. The notification messages may be provided to the message provider so they can be provided to the responsible resources. The provider profiles may be updated based on performance metrics associated with the message provider.

Abstract: A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.

Abstract: A display apparatus includes a tuner for selecting a desired channel; a decoder for decoding broadcasting signals (Y, U, V) inputted from the selected channel; a video processing unit for processing the decoded broadcasting signals into (R, G, B) signals; a gain adjustment unit for adjusting the gain value of the (R, G, B) signals processed by the video processing unit; a display unit for displaying the (R, G, B) signals the gain of which has been adjusted; and a control unit for detecting skin color from the (R, G, B) signals processed by the video processing unit and calculating luminance signal level to correct the luminance signal level of the (R, G, B) signals. The display apparatus can accurately correct skin color in low luminance level.

The wireless transmitting apparatus includes a data converter for mapping multibit digital data by a data symbol in accordance with a predetermined mapping table, for converting the data symbol to an analog signal, and for outputting the analog signal, and a wireless transmitter for modulating the analog signal and for transmitting the signal wirelessly. The wireless receiving apparatus includes a wireless receiver for demodulating a wireless signal received to an analog signal, and a data restoration section for converting the analog signal to a digital signal in accordance with a predetermined mapping table, conducting an inverse symbol mapping on the digital signal, and outputting the digital signal.

Abstract: Disclosed are a method of compensating colors in an image display device for users with color vision deficiency and a device of the same, enabling the users with color vision deficiency to view display images as vividly and naturally as normal users. The method for compensating colors in an image display device includes a step of determining whether a user is partially color blind or normal, and a step of controlling gain values of a plurality of color signals depending upon the user's color perceptivity so as to compensate colors displayed on a screen, if the user is determined to be partially color blind.

Abstract: The present invention relates to a method of determining the enzymatic activity of blood coagulation factor XIII by using purified fibrin monomer as a substrate of this enzyme. The enzymatic activity is determined by detecting the degree of cross-linking of fibrin monomer formed by the blood coagulation factor XIII and the fibrin monomer free of blood coagulation factor XIII is obtained by washing the preparation with citric acid solution. The present method can be effectively used for the validation of the other enzymatic assay methods for the blood coagulation factor XIII as well as the studies for the characterization of the blood coagulation factor XIII.
