Abstract:
An ultrasound backing member, an ultrasound probe including the ultrasound backing member, and a method of manufacturing the ultrasound backing member are provided. The ultrasound probe includes an ultrasound module comprising a transducer that converts ultrasound waves into an electrical signal or vice versa, and a backing member obtained by filling a porous foam-type body with a backing material that absorbs the ultrasound waves generated by the ultrasound module.
Abstract:
An electronic white board that includes a display configured to display a screen, a first sensor configured to sense a touch on the display, a second sensor configured to sense electromagnetic waves emitted from an object that touches the display, and a controller configured to perform a function that corresponds to the touch that is sensed by any one of the first sensor and the second sensor depending on whether the electromagnetic waves are sensed by the second sensor.
