A beamforming device includes a sampler configured to sample a signal reflected from a focal point and received to a transducer array; a mixer configured to separate the sampled signal into an in-phase component signal and a quadrature component signal; a low pass filter configured to perform filtering on the in-phase component signal and the quadrature component signal; a decimator configured to perform decimation on the filtered in-phase component signal and quadrature component signal; a sampling delay compensator configured to compensate a sampling time delay based on a preset time delay resolution for the decimated in-phase component signal and quadrature component signal; a phase rotator configured to compensate a phase delay based on a preset phase resolution for the in-phase component signal and the quadrature component signal for which the sampling time delay is compensated; and a delay calculator configured to calculate a time delay resolution and the phase resolution, and to apply each to the sampling delay compensator and the phase rotator.

Beamforming device, method of controlling the same, and ultrasound diagnostic apparatus

An accessory for portable device includes a case which is to be mounted on the portable device, the case including a through hole extending in one direction, and a guide rail provided along both sides of the through hole, a plate including guide grooves being configured to receive the guide rail on both sides thereof, the plate being guided by the guide rail so as to be movable along an extending direction of the through hole, a connecting part rotatably fixed to the plate, a ring part pivotably fixed to the connecting portion so as to have various angles with respect to the connecting part, and at least one uneven portion including concave-convex portions which are arranged along the guide rail for receiving protrusions of the plate to fix the plate to a plurality of positions.

Accessory for portable device

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.

Mounting member

A tuning device for a stringed musical instrument comprising a socket to receive a peg of the instrument, a shaft rotatably connected to the socket, a motor to induce rotation of the shaft, a first gear to reduce the shaft rotation and increase torque from the motor, the first gear being engaged to the motor, a second gear to exponentially reduce the reduced shaft rotation, the second gear being engaged between the shaft and the first gear, a cutter to trim a string of the instrument, and a housing to cover and protect the shaft, the motor, and the gears, where the cutter is attached to the housing opposing the socket.
