Powering Inaccessible Circuits and Communicating with them through Coupled Inductors

Abstract - The world today is full of unpowered electronic circuits that rely on contactless methods of receiving power and communicating with an external terminal. The most common example is “Tap cards” at points of sale, to pay fares on public transport, and so on. RF tags are increasingly entering warehouses, hospitals, and other inventory collections. Unlike optically scanned barcodes, electronic circuits today contain non-volatile memory and therefore information unique to each tag.
Most of these applications exploit weakly coupled coils to transmit power and data. How this works is not as obvious as it might seem.
I will show the circuit theoretic principles of these near-field links, and a rediscovery of Tesla’s oscillation transformer that leads to self-regulated power delivery through an inductive link that is, within limits, independent of coupling coefficient.
Speaker Bio - Asad Abidi received the BSc degree in Electrical Engineering from Imperial College, London in 1976, and the PhD from the University of California, Berkeley in 1982. He worked at Bell Laboratories, Murray Hill until 1985, and then joined the faculty of the University of California, Los Angeles where he is Distinguished Chancellor’s Professor of Electrical Engineering. With his students he has developed many of the radio circuits and architectures that enable today’s mobile devices.
Among other awards, Professor Abidi has received the 2008 IEEE Donald O. Pederson Award in Solid-State Circuits and the 2012 Best Paper Award from the IEEE Journal of Solid-State Circuits. The University of California, Berkeley’s Department of EECS recognized him as a Distinguished Alumnus in 2015. He was elected Fellow of IEEE in 1996, Member of the US National Academy of Engineering, and Fellow of TWAS, the world academy of sciences.

Abstract – Like electricity and water, internet access has become a critical utility for the home or office. Distance learning and working from home during the COVID-19 Pandemic highlighted the challenges with the current technologies. Rural and urban locations need to get higher bandwidth, lower latency, and more reliable internet access. Copper access technologies are reaching their limits and the cell phone network doesn’t provide enough bandwidth for home and business applications. The world has embraced fiber optics and specifically Passive Optical Networks (PON) for the future of internet access. The technology used for past, current, and future internet access will be explored with a detailed look at the latest PON fiber technologies.
Mr. Edward Boyd is the Chief Technical Officer and Co-Founder of Tibit Communications. Tibit Communications is a Northern California startup company developing Pluggable Network Interface solutions including the world’s first Micro-OLT in an SFP form factor. Before Tibit, Ed was the CTO and Co-Founder of Teknovus, Inc before it was acquired by Broadcom in March of 2010. Mr Boyd was Senior Technical Director for Broadcom Corporation working on the Ethernet Passive Optical Network (EPON) and Ethernet Protocol over Cable (EPoC) products before leaving to become a Co-Founder of Tibit. Mr. Boyd has more than 20 years of experience defining and developing ASICs for data communications, cable access networks, and telecom access networks. Mr. Boyd holds numerous patents in areas of cable modem, PON, and Ethernet networks. Mr. Boyd has been active in CableLabs, ITU-T (BPON/GPON), and IEEE 802.3 (Ethernet/EPON /EPoC) standards bodies.
The convergence of Internet of things (IoT) and Artificial Intelligence (AI)
Mr. Shivakumar Mathapathi
Co-Founder and CTO
Xtrans Solutions LLC
Thu, 09/02/2021
The rapid growth of billions of IoT connected devices encourages to train the machine for delivering desired output parameters. The relationship between internet of things, machine learning and artificial intelligence is demonstrated through many research and development of products and services. Dataset collected from IoT devices are now available for analysis and predicting future trends. One of the embodiments is to forecast weather based on the previous data collected. This talk will discuss and demonstrate the convergence of IoT connected devices such as temperature, humidity and connect to the machine learning model to predict readings for subsequent week/days. Practical application of python enabled ML linear regression implementations will be shown. Mathematical modeling and analyzing data using matplotlib and various python library function such as NumPy and Pandas will be exhibited exercising Jupyter notebooks and open source hardware (Raspberry Pi).
Shivakumar (Shiva) Mathapathi has over 25 years of experience in product development, design, and faculty. Shiva is a seasoned technologist, instructor and practitioner on the Internet of Things (IoT) with extensive experience as lead faculty, lab practice and mentorship in executing smart city, smart agriculture, assisted living and other IoT-related projects.
