Abstract: A solid electrolyte membrane for a solid-state battery and a battery comprising the same is provided. The battery may comprise lithium metal as a negative electrode active material. The solid electrolyte membrane comprises an inhibiting layer, which is preferably capable of inhibiting growth of lithium dendrite, because it includes an effective amount of a dendrite growth-inhibiting material, which is capable of ionizing lithium deposited in the form of metal. Thus, when lithium metal is used as a negative electrode for a solid-state battery comprising the solid electrolyte membrane, it is possible to delay and/or inhibit growth of lithium dendrite, and thus to effectively prevent an electrical short-circuit caused by dendrite growth.

Abstract: In various embodiments, an antenna array may comprise a dielectric; a first patch antenna disposed on a first region of the dielectric; a second patch antenna disposed on a second region of the dielectric; and a ground layer including a first sub-ground layer in contact with a lower portion of the first region of the dielectric, a third sub-ground layer in contact with a lower portion of the second region of the dielectric, and a second sub-ground layer spaced apart from a lower portion between the first region and the second region of the dielectric.

Abstract: A method and device for searching for a network in a wireless communication environment supporting a plurality of communication methods are provided. An example method to support Simultaneous Voice and LTE (SVLTE) and Circuit Switch-FallBack (CSFB) involves determining a communication mode when a booting or rebooting event or no-data service event occurs, and only searching for a signal related to a selected one of the communication modes, thereby reducing total scan time needed to access a network.

Abstract: An image forming apparatus and a method to control the same. The image forming apparatus determines whether the object to be printed is real money. If the object is real money, the image forming apparatus prints a variety of counterfeit money discrimination information (e.g., the counterfeit money preventing pattern, the warning message, or the unique number of the image forming apparatus used for printing the money) on the back side of the copy of the money, and prints the original image of the money on the front side of the copy of the money without any change. Therefore, the image forming apparatus can color-print the original image of the money without any change, and can prevent the copied money from being used as counterfeit money.

Abstract: An image forming apparatus and a method of controlling the image forming apparatus. When print data is printed, the remaining amount of toner of each of the CMYK colors is analyzed. When print data is printed, the apparatus analyzes an original color of the print data and analyzes respective remaining amounts of toner of a plurality of colors. If the remaining amount of toner of any of the plurality of colors is insufficient, the apparatus generates a plurality of corrected sample images having colors similar to the original color, the similar colors being obtained by combining colors of toner other than that of the insufficient remaining amount of toner, and prints a report including the generated plurality of corrected sample images. This allows the user to print their preferred colors even if the remaining amount of toner of any color is insufficient, thereby increasing convenience and economic efficiency.

Abstract: A method of enabling software installed in an image forming apparatus, and an image forming apparatus to perform the method, the method including connecting a first license device having at least one license which can enable the software to the first image forming apparatus; enabling the software using the at least one license; reconnecting the first license device to the first image forming apparatus; and disabling the enabled software.
