Abstract:
There are disclosed embodiments for controlling an operation of an ultrasound system based on an impact applied thereto. In the ultrasound system designed to operate in a plurality of diagnostic modes, a user may be verified based on the impact pattern applied to the ultrasound system. Also, a desirable diagnostic mode of the ultrasound system may be selected and executed based on the impact pattern. The ultrasound system may include an ultrasound diagnostic unit to form ultrasound images based on ultrasound echo signals reflected from a target object. An impact detecting unit may detect impacts applied to the ultrasound diagnostic unit from a user to thereby output impact pattern information. A control unit may control an operation of the ultrasound diagnostic unit based on the impact pattern information so that the diagnostic mode corresponding to the impact pattern information may be executed.

Abstract:
An apparatus for measuring on-chip characteristics in a semiconductor circuit is provided. The apparatus for measuring the on-chip characteristics includes an oscillation unit, a timing test unit, and a selection unit. The oscillation unit is configured to selectively output a first oscillation signal responsive to a first control signal. The timing test unit is configured to generate a second oscillation signal using an input clock signal, generate a pulse from the second oscillation signal responsive to a second control signal, and determine whether an operating time violation has occurred based on a comparison of the second oscillation signal and the pulse. The selection unit is configured to select one of the output of the oscillation unit and the output of the timing test unit responsive to a test mode signal. The apparatus is configured to measure an on-chip delay using a period of the first oscillation, or to measure a timing margin of the semiconductor circuit using an output of the timing test unit, based on an output of the selection unit.

The method includes: obtaining a plurality of 2D images; arranging the plurality of 2D images in a 3D space based on predetermined criteria;obtaining spatial coordinates of each of the plurality of 2D images arranged in the 3D space; generating a 3D model of the plurality of 2D images arranged in the 3D space based on the spatial coordinates; changing attribute information of the plurality of 2D images arranged in the 3D space; and displaying the 3D model and the plurality of 2D images whose attribute information is changed.
Abstract:
An ultrasound diagnostic apparatus for providing on a display an ultrasound image including a target object and a pointer movable on the ultrasound image, comprises: an ultrasound image providing unit configured to provide an ultrasound image including a target object; a contour line extracting unit configured to extract a contour line of the target object in the ultrasound image; a coordinate recognizing unit configured to detect cross points while the pointer crosses the contour line and recognize the coordinates of the corner points; a user input unit configured to receive instructions from a user, said instructions including a selection instruction to select measure points among the cross points and a measure instruction to measure a size of the target object; a measuring unit configured to measure a size of the target object in response to the measure instruction based on coordinates of the measure points selected in response to the selection instruction; and an output unit configured to output the ultrasound image, the pointer, the contour line, the measure points and the size of the target object.
Abstract:
The present invention discloses a method for preparing an impregnating pitch which is used for the manufacture of carbon-carbon composites having excellent mechanical properties at an ultra high temperature, abrasion resistance and the like, wherein the impregnating pitch having a low viscosity and an improved carbonization yield is provided by facilitating cross-linking reactions between the aromatic compounds in the pitch, while eliminating heat treatment.
Abstract:
An apparatus for discharging tissue that is folded several times and stacked is provided. The apparatus includes a cartridge that holds stacked tissue and has a through hole at one end, and a holding member that is disposed adjacent to the through hole of the cartridge and pivots on an axis to grasp and remove tissues one at a time from the top of the stack through an arm. The inventive apparatus allows a user to easily replace tissue and check the amount of tissue used and the amount left to use through visual means. The apparatus virtually eliminates the problem of tissue dispensing failure, and has increased precision and reliability and reduced dispensing time over conventional apparatuses.
