ParaCom An IoT based affordable solution enabling people with limited mobility to interact with machines

There are many people in this world who don’t have the ability to communicate with others due to some unforeseen accident. User’s who are paralyzed and/or suffering from different Motor Neuron Diseases (MND) like Amyotrophic Lateral Sclerosis (ALS), Primary Lateral Sclerosis etc, by making them more independent. Patients suffering from these diseases are not able to move their arms and legs, lose their body balance and the ability to speak. Here we propose an IoT based communication controller using the concept of Morse Code Technology which controls the smartphone of the user. This paper proposes a solution to give the user ability to communicate to other people using machine as an intermediator. The device will require minimal inputs from the user.

More than Drivers in Motor Drives: Closing the Loop

This paper presents the problematic associated to the design of a complete motor drive, exposing all available and missing blocks at this moment. We proceed by dividing the power drive into basic functions – control, different power supplies, isolated communication, controller interfacing, current monitoring – and we present for each of these functions an implementation example. Implementation examples shown are based on high-temperature X-REL parts such as XTR26020 Isolated Intelligent Gate Driver, XTR40010 Isolated Two Channel Transceiver, XTR30010 PWM Controller, XTR70010 and XTR70020 Low-dropout Linear Regulators and XTR50010 Bidirectional Multichannel Level Translator. A drive solution based on the XTR26020, presented for the first time in this paper, is explained and compared against previous art. Main characteristics of the new linear regulator XTR70020 are presented, showing the best-in-class dropout voltage, which outperforms the closest competitor by a factor of three. For all parts featured, tests results at an ambient temperature up to 230°C (even higher in some cases) are presented.

Ethernet Controller and Serial Interface Conversion Technology Based on FPGA

The FPGA-based 10/100M Ethernet MAC controller and universal asynchronous serial communication controller are designed and connected on chip in this paper. Such functions as writing data transmitted by the serial interface to the Ethernet controller and sending them to the network, and serially outputting network data received by the Ethernet controller are implemented and interconnection communications between Ethernet and the serial are achieved, possessing great practical values in system test. Modularization design is performed on the whole system with VHDL in this study, whose hardware application is verified on Xilinx Virtex2P XC2VP30 development board. The simulation results prove that the design has reliability, stability and good applications in the data transmission test.
