Built-In Self Test of High Speed Analog-to-Digital Converters

Edinei Santin, Luis B. Oliveira, and Joao Goes

Summary

In this paper the authors discuss the use of built-in self-test (BIST) techniques for testing high speed ADCs and present a specific solution in which the analog input signal and the clock are generated internally. This fully integrated, low cost, and reconfigurable architecture for coherent self-testing of high-speed ADCs is based on two synchronized phased-locked loops, one to synthesize the analog input signal and another to synthesize the clock signal for the ADC under test. This synchronization is a key feature of the proposed approach, since it allows coherent sampling. With coherent sampling, the digital output data of the converter are well-behaved and their spectrum is unambiguous, since it is not necessary to worry about spectral leakage, windowing, etc.

Smart Pen-Shaped Digital Multimeter System Based on IoT and Cloud

Kun Xia, Hua Su, Jiawen Ni, Bangzheng Liu, Yanghong Ye, and Han Li

Summary

With the rapid development of integrated circuit technology, a favorable condition has been created for miniaturization, intelligence, and digitization of the measurement instruments. Meanwhile, with the advent of the Internet of Things, another possibility for advancement of the digital multimeter (DMM) is found. A DMM is designed to measure some key electrical parameters such as dc voltage, ac voltage, and resistance. In this article, a smart pen-shaped digital multimeter (PDMM) is proposed, which is more compact in structure and more intelligent in function. By employing a smartphone as the display, the volume of DMM is reduced. Through Bluetooth, PDMM can communicate with a smartphone, where data cloud management can be implemented.

Survey on Assistive Technologies for People with Dementia

Fernando Luís-Ferreira, Majid Zamiri, João Sarraipa, Gary McManus, Philip O’Brien, and Ricardo Goncalves

Summary

The number of people living with Dementia in societies is now rising at an unprecedented rate. Neither decisive treatment, nor effective medicines have been introduced to help society cope with such age associated pathologies. However, one promising alternative to this emerging crisis has been the adoption of Assistive Technologies. This paper provides an overview about recent findings in this field of study and also address some available technologies that have potential application for Dementia sufferers. The findings provide insight into the types and percentages of suggested technologies for each classification that aim to be useful for those researching the field or who want to know state of the art in this presently relevant domain. Concluding points and discussion are presented subsequently.

Fog Computing Context Analytics

Nikos Papageorgiou, Yiannis Verginadis, Dimitris Apostolou, and Gregoris Mentzas

Summary

Through this article, the authors introduce the basic methods of context classification and prediction, and we present their application to facilitate fog infrastructure management. A fog infrastructure typically includes cloud, stationary as well as mobile computing devices which host distributed software systems. Fog infrastructures utilize sophisticated algorithms and advanced software or hardware sensors to make intelligent decisions to increase quality of service, utilization of resources and scalability. Context classification and prediction uses multivariate, sensor-generated data to infer contextual knowledge about the status of a fog resource, which can facilitate decision making with respect to infrastructure management by supporting auto-scaling and infrastructure optimization strategies.

Satellite Overall Test Matrix

Malik Khalfallah and Parisa Ghodous

Summary

In this article, the authors discuss a methodology for functional testing for satellite systems and its supporting software called Overall Test Matrix (OTM). Defining functional tests for satellites relies on the measurements embedded in satellite telemetries. The paper presents how these telemetries are created and managed and how test specifications use satellite telemetries to define success criteria. The authors discuss how the OTM supports the definition and execution of tests while ensuring an end-to-end data continuity. Their implementation replaces the currently used excel files that do not ensure data continuity.

Future Trends in I&M
Industrial Strength Security
Richard Nelson

Summary

A note from Melanie Ooi: Cyber-security is a particularly important concern as we race towards Industry 4.0 and IoT. Our guest columnist, Dr. Richard Nelson, is the project leader of a NZD $12.2 Million Cyber-security project funded by New Zealand's Ministry of Business, Innovation and Employment. This project, named STRATUS, commenced in 2014 and aims to empower users to be able to control the security of their data in the Cloud, and to create security tools and services for companies to sell. He shares with us some important insights on the role that the instrumentation and measurement community can have in the Cyber-security road map.
