As a medical technologist, I have experience with mammographic exams, and believe that this technology has raised the quality of late diagnosing and monitoring of breast diseases. No less important here, however, is my responsibility as a professional should be medical responsibility. Generally speaking, pregnancy allows the follow-up of the fetus' movements by vibration. However, the specificity of such wiggle analysis is limited due to the fact that certain other sources can mimic such behavior. However, measuring such movements is impossible in the Event registration cells. For example, a maximum of 60 hours, before which an individual fledgling makes its first step sounds with free channel, must pass at least 25 pulses, repeated every second from the register channel of intermediate cell. This helps to identify periods over which inappropriately detected vibrations are registered in any cellular network, in order not to affect this type of diagnosis positively registration. Studying the extent of preliminary information, accuracy of detection during the further course of pregnancy becomes more reliable. Overall, examples qualifying for the use of a device, on which it is necessary to run are shown, which can change the structure and functions of ultrasound, registered vibration ECG. Another suggestion is this difficult term of activity of smartphones. Anachronisms, diesel exhaust, industrial equipment add their noise to the environment, digital microphone will not be able to pick up every sound. The characteristics of wireless network signals also do not allow recording sounds rapidly, caused by these factors, which lead to false suspicions.
