    Abstract: A cold brew coffee extraction device for adjusting the sonic vibration based on the sound signal includes: a current support extended in one direction and configured to apply an alternating current in a tangential direction of an outer peripheral portion; a magnetic vibrator accommodating one end of the current support therein, and configured to generate a magnetic field in a direction of crossing over the current support to be vibrated in a longitudinal direction of the current support due to a change in a polarity of the alternating current; a plate coupled to the magnetic vibrator to transmit the vibration to a fluid including a particulate matter; and a vibration adjustment circuit configured to, in a first mode, adjust the vibration only based on setting information inputted through a user interface, and in a second mode, to adjust the vibration based on the setting information and an external sound source.

    Abstract: A real time file alteration sensing-based automatic backup device includes: a backup target selection unit selecting one or more backup targets that are accessible over a network and are subjected to backup; a content alteration sensing unit sensing in real time whether contents of the one or more backup targets are altered or scanning all the backup targets for sensing at particular-time intervals; a backup data generation unit generating, when the alteration of the content of the backup target is sensed, backup data containing information required for recovery of the sensed backup target; and a backup data storage unit storing the generated backup data.

    Abstract: The present invention relates to a contact lens for presbyopia and, more specifically, to a contact lens for presbyopia, providing both a far-distance vision area and a near-distance vision area in one contact lens, and continuously forming a lens magnification of the far-distance vision area and the near-distance vision area of the dominant eye and the non-dominant eye while changing the sizes of the far-distance vision area and the near-distance vision area of two eyes according to the dominant eye and the non-dominant eye, such that an intermediate-distance area is partially overlapped, thereby continuously providing a near-distance vision area at a far distance by a neural summation phenomenon that selects a clearly visible image in both eyes.
