Abstract: A detonator includes a control circuit and a charging circuit. The control circuit receives a first signal transmitted using a voltage applied to a cable by a blasting device and transmits a second signal to the blasting device using a current flowing to the cable. The charging circuit performs a charging operation by receiving the voltage through the cable. The charging circuit stops the charging operation while the control circuit transmits the second signal to the blasting device.

Abstract: A method for modeling an internal object of a human body includes the step of obtaining the original three-dimensional volume data of the internal object of a human body utilizing an ultrasonic imaging device. Thereafter, a desired area of the obtained original three-dimensional volume data is selected and the image quality of the desired area is enhanced. The desired area of the three-dimensional volume data is transformed into a fair shape data. The fair shape data is decimated while a modeled shape is maintained. Finally, a three-dimensional model is shaped using decimated shape data.
