Predicting the Risk of Electromagnetic Interference in Hospital Equipment Using Fuzzy Neural Networks
Abstract: Healthcare facilities are populated with electronic medical devices and many other wireless electronic devices for work purposes and for personal use. As they operate, electronic devices emit electromagnetic signals raising concerns of possible electromagnetic interference (EMI) to medical equipment from other devices such as mobile phones, Radio Frequency Identification (RFID) systems and microwaves. EMI could also emanate from magnetic fields of other medical equipment such as dental equipment and magnetic resonance imaging (MRI). This research employs a wireless sensor network to monitor the electromagnetic compatibility of medical equipment by detecting the amount of radiation in its vicinity and predicting the possibility of electromagnetic interference using a fuzzy neural network approach. To detect the electromagnetic signals, a Radio Frequency meter equipped with low-frequency and high frequency probe, connected to an ESP32 microcontroller is used. The collected data is sent by Wi-Fi to the cloud for storage and analysis. A fuzzy neural network is introduced to the EMC/EMI monitoring to determine when electromagnetic signals are likely to be at their peak values with a chance to interfere with the normal operation of other equipment. The findings have shown that EMI prediction using ANFIS can be performed with high accuracy. The trained model demonstrated an excellent prediction capability when evaluated using test data, with RMSE of 0.334172, R2 of 0.9636 and MSE of 0.180645. The study aids biomedical technicians and engineers to manage the electromagnetic compatibility of medical devices and improve overall hospital safety to both patients and staff. Read more
Assessing the Role of Broadband Connectivity via Biomedical Devices in the Provision of Macro-Scale Health Care in the Provinces of Rwanda
Problem Statement and Research Objective
Broadband internet is widely known to enhance digital connectivity, which has not just important
economic implications (Calderón and Servén 2014; Czernich et al. 2011; Dedrick et al. 2003; Ding et al.
2008; Martin 1998; Sharon E. Gillett et al. 2006), but also health impacts (Tomer et al. 2020). At the
same time, broadband access also presents capacity challenges as only those with the skills to
incorporate such enhanced information access in their work (Autor et al. 2003), let alone who have
access to information to connect to the Internet (Hargittai 2002), have been found to see those benefits.
As such while broadband internet has the potential to serve as a catalyst for economic development in
low-income areas (Tomer et al. 2020), these are precisely the areas with acute capacity constraints that
are less likely to able to translate this into value. In other words, broadband penetration throughout a
region has the potential to compound ex...
