Recent Study on Design and Development of a Wearable Device to Monitor Vital Signs of Preggers | Chapter 13 | Advanced Aspects of Engineering Research Vol. 3

 When technology advances, we cannot afford to ignore any wearable device that is most suitable for pregnant women. Our proposed system is a wearable device that tracks expectant mothers' health and transmits data to the appropriate physician, especially in rural areas. Doctors will offer higher quality medical services and more personalised healthcare to these women using real-time wearable devices. This health-monitoring system would enable a pregnant woman to communicate with a doctor with nearly full functionality. The main goal of this system is to take preventive measures such as continuous health screening of patients from an early age and to provide advice on how to reduce prenatal risks. It can only be used after the 16th week of pregnancy. The health monitoring unit continuously monitors the womb's body temperature and pulse, and sends the data to a gynaecologist at a remote location via GSM if there are any deviations from the standard value. The use of innovative technology for pregnant women's treatment allows for better care and, as a result, pregnancy-related mortality can be decreased significantly.

Design of a Broadband Inverted Conical Quadrifilar Helix Antenna and a Small GPS Helix Antenna | Chapter 2 | New Insights into Physical Science Vol. 1

This chapter introduces two type helix antennas. One is a broadband inverted conical circularly polarized quadrifilar helix antenna (QHA). The antenna has many good characteristics, including wide beam and broad bandwidth, which are achieved by utilizing inverted conical geometry and adjusting the dimensions of the inverted conical support. The antenna is fed by a wideband network to provide 90° phase difference between the four arms with constant amplitude. The antenna impedance and axial ratio bandwidth values are more than 39% and 31.5%, respectively. The measured results coincide well with the simulated ones, which verified the effectiveness of the proposed design. Another step type helix line technology is also proposed to reduce the size of helix antenna. A small GPS helix antenna using the step helix line technology is designed, the antenna size is 0.032λ×0.032λ×0.063λ, the maximum gain is 5.3dBi, the peak to peak of circumference gain pattern within 0.3dBi, and the bandwidth is larger than 100MHz.
