Philips Research Book Series – serie

Battery Management Systems - Design by Modelling describes the design of Battery Management Systems (BMS) with the aid of simulation methods. The basic tasks of BMS are to ensure optimum use of the energy stored in the battery (pack) that powers a portable device and to prevent damage inflicted on the battery (pack). This becomes increasingly important due to the larger power consumption associated with added features to portable devices on the one hand and the demand for longer run times on the other hand. In addition to explaining the general principles of BMS tasks such as charging algorithms and State-of-Charge (SoC) indication methods, the book also covers real-life examples of BMS functionality of practical portable devices such as shavers and cellular phones. Simulations offer the advantage over measurements that less time is needed to gain knowledge of a battery's behaviour in interaction with other parts in a portable device under a wide variety ofconditions. This knowledge can be used to improve the design of a BMS, even before a prototype of the portable device has been built. The battery is the central part of a BMS and good simulation models that can be used to improve the BMS design were previously unavailable. Therefore, a large part of the book is devoted to the construction of simulation models for rechargeable batteries. With the aid of several illustrations it is shown that design improvements can indeed be realized with the presented battery models. Examples include an improved charging algorithm that was elaborated in simulations and verified in practice and a new SoC indication system that was developed showing promising results. The contents of Battery Management Systems - Design by Modelling is based on years of research performed at the Philips Research Laboratories. The combination of basic and detailed descriptions of battery behaviour both in chemical and electrical terms makes thisbook truly multidisciplinary. It can therefore be read both by people with an (electro)chemical and an electrical engineering background.

The advent of the digital era, the Internet, and the development of fast computing devices that can access mass storage servers at high communication bandwidths, have brought within our reach the world of ambient intelligent systems. To provide users with information, communication, and entertainment at any desired place and time in an intuitive, efficient, and effective way requires system intelligence that is generated by smart algorithms. The need for such algorithms, which run on digital platforms that are integrated into consumer electronics devices, has strengthened the interest in computational intelligence. This volume is the outcome of a series of discussions at the Philips Symposium on Intelligent Algorithms, which was held in Eindhoven on December 2002. It contains practical examples from this newly developing research field, which can be positioned at the intersection of computer science, discrete mathematics, and artificial intelligence.The examples include: machine learning; content management; vision; speech; content augmentation; profiling; music retrieval; feature extraction; audio and video fingerprinting; resource management; multimedia servers; network scheduling; and IC design.

Dynamic and Robust Streaming in and between Connected Consumer-Electronic Devices addresses a subject that is becoming more important over the years. On the one hand the arrival of home networks is imminent, and on the other hand we notice that chips integrate more and more functionality. The home network interconnects the Consumer Electronic (CE) devices in the home, and the individual CE-devices incorporate the chips to realize a ubiquitous streaming of video streams over this network.This book provides a comprehensive overview of the challenges that face us. The book shows that there are many similarities between traditional networking and networks in the chip. However, there are some different operational conditions that lead to original solutions.Dynamic and Robust Streaming in and between Connected Consumer-Electronic Devices focuses on the robustness aspects of the chosen technologies in the area of video streaming. Management of resources such as memory, bandwidth, CPU cycles, bus–cycles is an aspect that is prominent in many of the sections.

Ambient Intelligence is one of the new paradigms in the development of information and communication technology, which has attracted much attention over the past years. The aim is the to integrate technology into people environment in such a way that it improves their daily lives in terms of well-being, creativity, and productivity. Ambient Intelligence is a multidisciplinary concept, which heavily builds on a number of fundamental breakthroughs that have been achieved in the development of new hardware concepts over the past years. New insights in nano and micro electronics, packaging and interconnection technology, large-area electronics, energy scavenging devices, wireless sensors, low power electronics and computing platforms enable the realization of the heaven of ambient intelligence by overcoming the hell of physics. Based on contributions from leading technical experts, this book presents a number of key topics on novel hardware developments, thus providing the reader a good insight into the physical basis of ambient intelligence. It also indicates key research challenges that must be addressed in the future.

The rapid growth in electronic systems in the past decade has boosted - search in the area of computational intelligence. As it has become increasingly easy to generate, collect, transport, process, and store huge amounts of data, the role of intelligent algorithms has become prominent in order to visualize, manipulate, retrieve, and interpret the data. For instance, intelligent search techniques have been developed to search for relevant items in huge coll- tions of web pages, and data mining and interpretation techniques play a very important role in making sense out of huge amounts of biomolecular measu- ments. As a result, the added value of many modern systems is no longer determined by hardware only, but increasingly by the intelligent software that supports and facilitates the user in realizing his or her objectives. Overthepastyears, considerableprogresshasbeenmadeintheareaofc- putational intelligence, which can be positioned at the intersection of computer science, discrete mathematics, and cognitive science. This has led to a gr- ing community of practitioners within Philips Research that develop, analyze, and apply intelligent algorithms. The Symposium on Intelligent Algorithms (SOIA) intends to provide this community of practitioners with a platform to exchange information. The ?rst edition of SOIA, held in 2002, addressed the topic of intelligent algorithms in ambient intelligence.

Fred Boekhorst Steady progress in Information and Communication technology has advanced the Internet, once merely a tool for exchange of scientific infor- tion between universities, to a platform that enables the transformation of our society. In this new, digital society, people can take more informed decisions because of new mechanisms for finding what you’re looking for [Google], new mechanisms of accessing background knowledge [Wikipedia], new ways of engaging with one another [chat], new ways of trading goods [e-Bay] and many more. While these represent already profound changes in our lifestyle, the effects of digitizing society have just begun. So far, the Internet has made information accessible through computer screens but the next wave will be “The Internet of Things”. Environments will become smart and responsive to the presence of people and objects. The key underlying technology here is embedded sensor technology that allows sensors to monitor people and their environment and to communicate me- urements. The combination of the Internet [representing Intelligence and p- vasiveness] and sensor networks [representing Ambient probing] will unlock many new applications, for example in the field of optimized logistics, smart agriculture or more intelligent living environments. At Philips, we have set up three different laboratory environments that aim to research how an int- ligent environment could help people. One of those environments is called “Care-Lab” in which we investigate how technology could help elderly ma- tain an independent lifestyle.

Battery Management Systems: Accurate State-of-Charge Indication for Battery-Powered Applications describes the field of State-of-Charge (SoC) indication for rechargeable batteries. With the emergence of battery-powered devices accurately estimating the battery SoC, and even more important the remaining time of use, becomes more and more important.An overview of the state-of-the-art of SoC indication methods including available market solutions from leading semiconductor companies, e.g. Texas Instruments, Microchip, Maxim, is given in the first part of this book. Furthermore, a universal SoC indication system that enables 1% or better accuracy under all realistic user conditions is developed. A possible integration with a newly developed ultra-fast recharging algorithm is also described.The contents of this book builds further on the contents of the first volume in the Philips Research Book Series, Battery Management Systems - Design by Modelling. Since the subject of battery SoC indication requires a number of disciplines, this book covers all important disciplines starting from (electro)chemistry to understand battery behaviour, via mathematics to enable modelling of the observed battery behaviour and measurement science to enable accurate measurement of battery variables and assessment of the overall accuracy, to electrical engineering to enable an efficient implementation of the developed SoC indication system. It will therefore serve as an important source of information for any person working in engineering and involved in battery management.

In March 1979, a prototype of a ‘Compact Disc (CD) digital audio system’ was publicly presented and demonstrated to an audience of about 300 journalists at Philips in Eindhoven, The Netherlands. This milestone effectively marked the beginning of the digital entertainment era. In the years to follow, the CD-audio system became an astonishing worldwide success, and was followed by successful derivatives such as CD-ROM, CD-RW, DVD, and recently Blu-ray Disc. Today, around the thirtieth anniversary of the milestone, it is taken for granted that media content is stored and distributed digitally, and the analog era seems long gone. This book retraces the origins of the CD system and the subsequent evolution of digital optical storage, with a focus on the contributions of Philips to this field. The book contains perspectives on the history and evolution of optical storage, along with reproductions of key technical contributions of Philips to the field.

Reservation procedures constitute the core of many popular data transmission protocols. They consist of two steps: A request phase in which a station reserves the communication channel and a transmission phase in which the actual data transmission takes place. Such procedures are often applied in communication networks that are characterised by a shared communication channel with large round-trip times.In this book, we propose queuing models for situations that require a reservation procedure and validate their applicability in the context of cable networks.We offer various mathematical models to better understand the performance of these reservation procedures. The book covers four key performance models, and modifications to these: Contention trees, the repairman model, the bulk service queue, and tandem queues.The relevance of this book is not limited to reservation procedures and cable networks, and performance analysts from a variety of areas may benefit, as all models have found application in other fields as well.

The authors of this book analyze the influence of specific everyday life situations and contexts on the emotional state of people and the ways in which this can impact measurements of user experience. The book anticipates a future in which products and machines know how we feel and adapt to the feelings they sense (music systems that effectively enhance our current mood with a personalized choice of music, computer dialogues that avoid upcoming frustration, and photo cameras that take pictures whenever we're excited). In all these situations, knowledge of the emotional state of the user is prime information.A previous book published in the Philips Research Book Series, "Probing Experience", illustrated ways to evaluate the user experience through behavioural and physiological parameters. The present book focuses on the influence of context in these measurements. The everyday-life contexts of future products and machines will be always specific, especially in comparison to the standard laboratory situation. Context can impact the experience measurements and influence the occurrence and characteristics of certain signals. On the other hand, independent knowledge of the context could be very valuable for the interpretation of experience measurements. This book provides an overview of the present knowledge on the impact of context, and advocates the need for a joint understanding of its role in the measurement of experience. The authors comprise many experienced researchers on this topic with a wide variety of backgrounds, including business and academia, covering a broad range of context situations.
