Abstract: A mounting member for mounting a mobile device and a mobile device accessory of being fixed to one face of the mobile device and having a ring on an object is disclosed. The mounting member includes a body having a plate shape, a ring insertion hole penetrating the body and extending along one direction of the body, the ring inserting hole being configured for the ring to be inserted downwardly thereinto, and a fixing hole formed on a lower surface portion of the body to cross the ring insertion hole, the fixing hole being configured to fix the ring inserted in the ring insertion hole and rotated to the body.

Abstract: Systems, devices, and methods for providing a ring holder stand for a portable digital device, such as a smartphone, tablet, portable media player and the like, that can be easily separated from and re-attached to the portable digital device as needed by a user, so that the ring holder stand can be removed while the portable digital device is being recharged so as to stop the chances of causing fire or thermal burn that may occur if the metal ring holder stand remains attached to the portable digital device.

Abstract: Provided is an ultrasonic imaging apparatus including: an inputter configured to receive an input of a region of interest (ROI) from a user; a beamformer configured to perform transmission/reception focusing with respect to a virtual source to be used for a synthetic aperture focusing method; a display; and a main controller configured to determine a position of the virtual source on the basis of an image quality in the received ROI and control the display to display the determined position of the virtual source.

Abstract: A mounting member for mounting a mobile device and a mobile device accessory of being fixed to one face of the mobile device and having a ring on an object, the mounting member includes a body, a slot portion being formed in a part of the body and having a receiving groove for receiving the ring and a pressing portion disposed inside the receiving groove and configured to elastically press the ring to be located in the receiving groove.

Abstract: A suction apparatus according to the present invention includes a suction plate, a fixing shaft, a supporting plate, an adhesive member, and a housing. The suction plate is configured to adhere to a suction subject surface. The fixing shaft is configured to be fixed to a central portion of the suction plate, and is configured to upwardly transport the central portion of the suction plate to be separated from the suction subject surface to form a sealed space between the suction plate and the suction subject surface in a pressure lower than an atmosphere pressure. The supporting plate has a ring shape and prepared on a periphery of the suction plate, and is combined with the suction plate. The adhesive member has a ring shape, and includes an upper surface fixed to a lower surface of the supporting plate and a lower surface configured to adhere to the suction subject surface, to prevent inflow of an air toward the sealed space.
