Arrhythmia is an irregular heartbeat where the blood may not be delivered effectively throughout the body and cause sudden cardiac arrest (SCA). Immediate treatment is required to prevent SCA. However, most of the existing electrocardiogram (ECG) monitoring devices are bulky, cost expensive and lack arrhythmia detection and classification system. This paper proposes a front-end on-board graphical interface design of System-on-Chip (SoC) based arrhythmia detector which can be used as a first screening device for cardiac disease patient. The system consists of a knowledge-based arrhythmia classifier which is able to identify three types of arrhythmias which are ventricular fibrillation (VF), premature ventricular contractions (PVCs) and second-degree atrioventricular (AV) block. The system has been evaluated and benchmarked with ECG data from MIT-BIH arrhythmia database. The results show that its accuracy is up to 99.25% with a computation time of 6.385 seconds. It is highly portable and relatively inexpensive for installation in small clinics and home monitoring.

The Impact

The active stokehold protective garments (ASPG) can remove body heat of ship stokehold operators working in confined and extremely hot environment via conductive heat exchange from circulating water-cooled fluid next to the skin through the body-temperature-monitoring method. Hence, portable microclimate water-cooled thermoregulation systems (MWCTS) for the ASPG have been developed by using programmable embedded system-on-chip (PSoC) in this paper. The ASPG have advantages of longer cooling periods, better temperature-controlled capability, and excellent thermal somatosensory comfort. Furthermore, they could allow users to adjust comfortable temperature and also maintain long-term constant temperature by monitoring human temperature in portable MWCTS. Additionally, optimal control algorithm may enhance system efficiency to reduce the power consumption and extend the operating time effectively; thus, the velocity and temperature closed-loop control systems have also been improved in the portable MWCTS for the ASPG. Consequently, several experiments have been implemented and explored the impact of the heat transfer rate and verified the feasibility of the MWCTS for ASPF.

The intestinal microbial flora has risen to be one of the important etiological factors in the development of diseases like colorectal cancer, obesity, diabetes, inflammatory bowel disease, anxiety and Parkinson's. The emergence of the association between bacterial flora and lungs led to the discovery of the gut–lung axis. Dysbiosis of several species of colonic bacteria such as Firmicutes and Bacteroidetes and transfer of these bacteria from gut to lungs via lymphatic and systemic circulation are associated with several respiratory diseases such as lung cancer, asthma, tuberculosis, cystic fibrosis, etc. Current therapies for dysbiosis include use of probiotics, prebiotics and synbiotics to restore the balance between various species of beneficial bacteria. Various approaches like nanotechnology and microencapsulation have been explored to increase the permeability and viability of probiotics in the body. The need of the day is comprehensive study of mechanisms behind dysbiosis, translocation of microbiota from gut to lung through various channels and new technology for evaluating treatment to correct this dysbiosis which in turn can be used to manage various respiratory diseases. Microfluidics and organ on chip model are emerging technologies that can satisfy these needs. This review gives an overview of colonic commensals in lung pathology and novel systems that help in alleviating symptoms of lung diseases. We have also hypothesized new models to help in understanding bacterial pathways involved in the gut–lung axis as well as act as a futuristic approach in finding treatment of respiratory diseases caused by dysbiosis.

Obstructive Sleep

Cardiac arrhythmias during sleep are reported in almost half of the population suffering from obstructive sleep apnea (OSA). The most common are bradyarrhythmias and atrial fibrillation whereas premature ventricular contractions and nonsustained ventricular tachycardia are less frequent. The risk of arrhythmia is proportional to the body mass index (BMI), number of respiratory events per hour of sleep described with apnea/hypopnea index (AHI) and the level of oxygen desaturation during these episodes. Continuous positive airway pressure (CPAP) treatment in OSA reduces the incidence of cardiac arrhythmias therefore reduce mortality and morbidity from cardiovascular disease.

The need for miniaturization has been the driving force in chip manufacturing. The proliferation of IoT, robotics, consumer electronics and medical instruments pose unprecedented demands on the embedded system design. The area optimization can be achieved either by reducing the size of transistors or by optimizing (reducing) the circuit at the gate level. The first solution has attracted many researchers while the later has not been explored to its full potential. The aim is to design a System on Chip (SoC) to satisfy the dynamic requirements of disruptive technologies while occupying the lesser area. The design and testing of communication interfaces such as Serial Peripheral Interface (SPI), Inter-IC Communication (I2C), Universal Asynchronous Receiver and Transmitter (UART) are very crucial in the area optimization of microcontroller design. Since SPI being an important communication protocol, this work reports the preliminary research carried in the design and verification of it. In this work, Verilog is used for the design and verification of the SPI module. The results show that there is a drastic reduction in the number of Look-Up-Tables (LUTs) and slices required to build the circuit. We conclude that sophisticated optimization techniques of the circuit at the gate level has the potential to reduce the area by half.

Security Capability

The hardware security of embedded systems is raising more and more concerns in numerous safety-critical applications, such as in the automotive, aerospace, avionic, and railway systems. Embedded systems are gaining popularity in these safety-sensitive sectors with high performance, low power, and great reliability, which are ideal control platforms for executing instruction operation and data processing. However, modern embedded systems are still exposing many potential hardware vulnerabilities to malicious attacks, including software-level and hardware-level attacks; these can cause program execution failure and confidential data leakage. For this reason, this paper presents a novel embedded system by integrating a hardware-assisted security monitoring unit (SMU), for achieving a reinforced system-on-chip (SoC) on ensuring program execution and data processing security. This architecture design was implemented and evaluated on a Xilinx Virtex-5 FPGA development board. Based on the evaluation of the SMU hardware implementation in terms of performance overhead, security capability, and resource consumption, the experimental results indicate that the SMU does not lead to a significant speed degradation to processor while executing different benchmarks, and its average performance overhead reduces to 2.18% on typical 8-KB I/D-Caches. Security capability evaluation confirms the monitoring effectiveness of SMU against both instruction and data tampering attacks. Meanwhile, the SoC satisfies a good balance between high-security and resource overhead.
