Abstract: Disclosed herein is a method of compensating for the distorted secondary current of a current transformer. The method includes steps (a), (b) and (c). At step (a), the saturated section of the current transformer is detected. At step (b), fault current generated during a fault in a power system is represented using an AutoRegressive (AR) model, with the fault current being assumed to be a combination of a Direct Current (DC) offset component, a fundamental wave component and a harmonic component. At step (c), normal secondary current during the saturation of the current transformer is estimated using a plurality of pieces of sampled secondary current data, based on the estimated coefficient of the AR model.

Abstract: Disclosed is a solid state dye-sensitized solar cell employing a composite polymer electrolyte, which includes a photoelectrode, a counter electrode, and an electrolyte interposed between the photoelectrode and counter electrode. The electrolyte includes at least one of a middle molecular substance, a polymer mixture, and inorganic nanoparticles, and a redox derivative. The dye-sensitized solar cell reduces crystallinity of the polymer electrolyte to significantly increase ionic conductivity, and enables the polymer electrolyte to smoothly permeate into a titanium oxide layer to improve mechanical properties, thereby significantly increasing energy conversion efficiency. Accordingly, the dye-sensitized solar cell assures high energy conversion efficiency without an electrolyte leak, and thus, it can be stably and practically used for a long time.

Abstract: This invention discloses a method of protecting copyright of a digital video work by using a digital password technology and a digital watermark technology to prevent the unauthorized use of a digital video work. Such method adds a password into two color matrixes of such video work in advance, so that when such video work is published on the Internet, it can be played by a specified player. As long as a user enters the correct password into the specified player, a full visual effect of such video work can be obtained. If other players are used to play such video work, only partial gray-scale visual effect can be obtained. Users must request or buy a specific player and a password from the distributor of such video work to play the complete information to prevent piracy.

Abstract: An automatic calibration method for use in an electronic compass. Using the automatic calibration method, the electronic compass automatically calculates and corrects offset and scale values of a geomagnetic signal by detecting one rotation of a geomagnetic axis during a predetermined period of time. The electronic compass calculates an azimuth angle upon receiving geomagnetic data from the geomagnetic sensor, and finds maximum and minimum values of sensor signals of individual axes of the geomagnetic sensor using the received geomagnetic data such that it can correct or calibrate deviation of the azimuth angle. When a time consumed for calibration is the same or shorter than a maximum calibration effective time, the electronic compass determines whether a current state of the detected entry signal indicates a predetermined steady-state flow.
