Abstract: The present invention relates to a device for regenerating nerve cells and suppressing immune diseases, and more particularly, to a device for regenerating nerve cells and suppressing immune diseases, which uses a contact lens containing a conductive material to increase the effect of microcurrent on nerve cell regeneration and immune response suppression. The device for regenerating nerve cells and suppressing immune diseases comprises: a contact lens comprising a body configured to be worn on a cornea, and a conductive material inserted into the body and serving to induce a microcurrent generated outside the body; a plurality of channels configured to come into close contact with skins around eyes and to generate a flow of microcurrent on upper part of the contact lens; and a signal supply unit configured to supply electrical signals to the plurality of channels.

Abstract: Wireless charging devices and wireless charging systems are provided. The wireless charging devices may include a receiving part coil and an electromagnetic-wave shielding sheet on the receiving part coil. The electromagnetic-wave shielding sheet may have a specific magnetic permeability of 100 or greater from 100 khz to 300 khz and may include a metal foam including a soft magnetic metal component.

Abstract: The present application provides a method for manufacturing a metal alloy foam. The present application can provide a method for manufacturing a metal alloy foam, which is capable of forming a metal alloy foam comprising uniformly formed pores and having excellent mechanical properties as well as the desired porosity, and a metal alloy foam having the above characteristics. In addition, the present application can provide a method capable of forming a metal alloy foam in which the above-mentioned physical properties are ensured, while being in the form of a thin film or sheet, within a fast process time, and such a metal alloy foam.

Abstract: An apparatus for inputting a password using a game may include a password image display unit to display at least one group password image including at least one password image, in at least one region of a display device, a receiving unit to receive at least one piece of motion information from an external input device, a character image display unit to display, on the display device, a character image that may move based on the at least one piece of motion information, a determination unit to determine which of the at least one group password image the character image contacts, and to determine which of at least one password image included in the contacted group password image is selected when a contact takes place as a result of the determination, and an authentication unit to control a user authentication procedure to be performed based on password information corresponding to the selected password image.
