Discharge Method

RS485 interface is widely used in the area of industrial control and remote meter reading, which are often subjected to serious electrostatic damage. A new On-Chip TVS (OCT) structure without extra process modification and a novel electrostatic discharge method for RS485 transceiver IC have been proposed. It is composed of a serie of Zener diodes and fabricated in 5V/18V/24V 0.5µm CDMOS technology. A 100ns pulse width of the Transmission Line Pulsing (TLP) test is performed for this proposed OCT. The driver circuit itself can work as an ESD device as well. The OCT trigger voltage is compatible with the signal level of RS485 standard. The OCT device protection level of human-body-model (HBM) is up to 16.34kV. RS485 transceiver integrated with OCT has also been tested in order to verify its reliability. The results indicate that it can pass the IEC61000-4-2 contact ±10kV stress and IEC 61000−4−4 Electrical Fast Transient (EFT) ±2.2kV without any hard damages and latch-up issues. The RS485 transceiver integrated with the OCT allows error-free data rate transfer up to 500 kbps. The chip occupies a silicon area of 2.4×1.17mm2.

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.
