Abstract: A method for processing contents at an electronic device is provided. The method includes generating a first content corresponding to a user input applied to content via the electronic device, and displaying a floating user interface (UI), which displays first scrap information on the first content, on a screen of the electronic device.

Abstract: A cover unit includes: a body to which an ultrasound generator adapted to generate ultrasound is coupled; first slits disposed at a lower portion of the body in the form of multiple rings having different radii and spaced apart from each other, the first slits having a first width; second slits depressed from an upper surface of the body to communicate with the first slits and having a second width smaller than the first width; third slits depressed from the upper surface of the body and each disposed between adjacent second slits, the third slits having a third width smaller than the first width; a bottom formed under the first slits; a first sidewall formed between adjacent first slits; and a second sidewall formed between the second slit and the third slit.

Abstract: Disclosed is an ultrasonic wave transmission structure which is provided on a path of ultrasonic waves to amplify incident ultrasonic waves. The ultrasonic wave transmission structure includes: multiple rings each provided with a body portion having a different radius from other body portions and spaced apart from another body portion adjacent thereto and a slit disposed between adjacent body portions; and a membrane disposed in the multiple rings, wherein the mass of the membrane is adjusted to vary a resonant frequency in multiple sub-membrane regions.

Abstract: In a module for detecting a fingerprint, an electronic device using the module and a method for manufacturing an acoustic control member for the module, the module includes a contact member, a transducer, an impedance matching member, an acoustic control member and a signal processor. A fingerprint makes contact with the contact member. The transducer outputs an ultrasonic signal to the contact member and receives the ultrasonic signal reflected from the contact member. The impedance matching member is charged between the contact member and the transducer, to transmit the ultrasonic signal between the contact member and the transducer. The acoustic control member is inserted between the contact member and the transducer. The impedance matching member is charged inside of the acoustic control member. The signal processor makes electric contact with the transducer, to sense the fingerprint based on the received ultrasonic signal.

Abstract: A method for converting OFF (object file format) from three-dimensional polygon data into a quad edge data structure which includes a step to determine if an input triangle of object file format is a whole new triangle, a step to find two edges and perform splice operation if the input triangle is a whole new triangle in the determination step, a step to find a quad edge from vertex link of quad edge data structure if the input triangle is not a whole new triangle in the determination step, and a step to find a candidate edge for a splice operation by comparing the link generated in the preprocessing stage and the vertex link of quad edge data structure and performing the splice operation on the candidate edge and the new quad edge.
