Abstract: Global trend toward Edge Processing is not all about technology, not all about how many devices can we put on every person on the earth, and not at all about selling more technology. At the heart of this revolution is a paradigm shift that will propel us to build a responsible society that is more energy efficient, more productive, honoring individual safety and privacy. In this talk, we will discuss why it makes sense to embrace Edge Processing revolution, what technology companies like us are doing to drive its growth, challenges and opportunities ahead of all us.

Abstract: Self powered systems on chip harvest energy from their environment and remove the need for batteries, which is essential for allowing the Internet of Things to scale toward a trillion or more edge devices. This talk describes how self powered systems operate to meet application needs. Using an example industrial application, the application needs define requirements for the system on chip that support the harvesting context, the network needs, and computation at the edge. An example self powered system on chip shows how these capabilities are integrated into a device that intelligently operates without batteries.

Abstract: With standards such as 6TiSCH, IEEE802.15.4 TSCH and WirelessHART, the IoT has been going industrial for a number of years. Tens of thousands of such low-power wireless networks have been deployed in application domains as varied as Smart Factory, Smart Building, Smart Home and Environmental. Off-the-shelf products such as Analog Devices’ SmartMesh IP offer >99.999% end-to-end reliability and over a decade of battery lifetime. Innovation in this domain also comes from vibrant open-source communities. We will first go through an overview of the key technology of the IIoT, and talk about what standards and products are available today. We will show numerous examples of where they are being used, all drawn from years of experience in real-world deployments. We will finish by discussing the research challenges ahead, both on dependable and technology-agile networking, and on crystal-free “Smart Dust” type architectures.

Abstract: Today , the performance of image sensors exceeds the capabilities of the human eye and can provide more immersive experiences as a result. In addition, the image sensors for sensing can digitize various other kinds of information than typical 2 dimensional images where applications such as authentication, recognition, autonomous machine control, and wireless products further process this useful and efficient information. These latest sensors enhance the quality of services and the evolution of image sensing systems grow into a broader information conversion tool. In this talk, the requirements for smart vision sensors in high-speed and event-based processing systems for industrial automation and always-on sensing applications will be discussed. The performance requirements for these new application will be demonstrated. Finally, our vision of how the upcoming combination of Smart Vision Sensor and Artificial Intelligence technologies will profoundly influence our lifestyle, will be introduced.
