An ultrasound technician is a very valuable job in the world of health care. Also called a diagnostic medical sonographer, an ultrasound tech uses special machines and equipment that operate on sound waves to determine or diagnose medical problems for patients.There are specializations within the field and some sonographers do branch off into these areas.lso called a diagnostic medical sonographer, an ultrasound tech uses special machines and equipment that operate on sound waves to determine or diagnose medical problems for patients.

Flip Chip Flip chip is the mounting of a chip with its active side facing the substrate. This die orientation is âflippedâ from the traditional packaging style, which uses bonding wires to connect the package to the die. In flip chip, the electrical interconnection between the chip and substrate is established by using solder bumps.
A digital logic circuit that can be in one of two states which it switches (or toggles) between under control of its inputs. It can thus be considered as a one bit memory. Three types of flip-flop are common: the SR flip-flop, the JK flip-flop and the D-type flip-flop (or latch). Early literature refers to the Eccles-Jordan circuit and the Eccles-Jordan binary counter, using two vacuum tubes as the active (amplifying) elements for each bit of information storage.
