ISA Expo, electronica: Sensors help define cold fusion, power supplies
Research Triangle Park, NC and Munich, Germany – Cold fusion will be a special keynote topic at ISA Expo 2008 in Houston in October and the following month electronica 2008 will highlight a variety of power supply technologies. Process sensors, instrumentation, and power protection and power control technologies are involved.
Dr. David J. Nagel, research professor at George Washington University, will present the Keynote/Rimbach Lecture at ISA Expo 2008, Oct. 15 in Houston.
The potential for a new sensing and instrumentation market with continued exploration and evolution of cold fusion technology will be discussed in the address, Instrumentation for Low Energy Nuclear Reactions, scheduled at 9 a.m.
An excerpt focuses on the history of cold fusion: “Two chemists announced in 1989 that they could produce nuclear reactions and energy under ordinary conditions of temperature and pressure. These reactions were termed‘cold fusion,’ even though no one really knew then what nuclear reactions might be occurring. In the years since 1989, hundreds of experiments have been done on what is now called Low Energy Nuclear Reactions, or the Fleischmann-Pons Effect. The total body of experimental evidence shows thatit is indeed possible to produce nuclear reactions at low input energies. However, the field remains controversial and poorly understood. There is no satisfactory theory now for what has been observed.”
Experiments require sophisticated instrumentation, including multiple sensors, and automated control of relevant conditions. Many believe that understanding, control, optimization and commercial exploitation of the new means to trigger nuclear reactions will follow in the future. If these advances occur, including significant scaling up in power levels, a new nuclear reactor industry will emerge. Sensing and control instrumentation will be critical.
For 36 years, Nagel has had positions of increasing responsibility at the Naval Research Laboratory. He has written or co-authored more than 150 technical articles, reports, and book chapters. In 1998, he became a research professor of George Washington University. He is general chairman of the 14th International Conference on Cold Fusion (Washington, DC). His R&D career paralleled developments in MEMS and nano-technology. He is recognized as an authority in MEMS and nano-technology-based sensors and wireless sensor systems.
The Rimbach Lecture honors Richard Rimbach (1885-1979), long considered the Father of ISA, for his lifetime of service to the industry and for his leadership in founding the Society.

Power technologies in Munich
|electronica 2008 will be in Munich Nov. 11-14, 2008.|
The following month, electronica 2008 at the New Munich Trade Fair Center, Nov. 11-14, 2008, will showcase virtually the entire breadth of power supply technologies and major trends. Among the anticipated 250 power supply-related exhibitors are products which include:
Configurations : Off line and other ac/dc power supplies, dc/dc converters including Voltage Regulator Modules (VRMs), full, half and quarter bricks, open and closed frames, hot plug, (n+1) redundant, inverters, and modular configurable systems;
Switching technologies : Square, resonant and quasi-resonant switching, and flyback, forward, and bipolar topologies;
Components : Ultra-fast, high-voltage, and high-temperature silicon carbide (SiC) devices, high temperature gallium nitride (GaN) devices, analog and mixed-signal controller ICs, digital microcontrollers, Power Factor Correction (PFC) controllers, synchronous rectifiers, standard and low ESR capacitors, thru-hole and surface-mount inductors, and power connectors;
Backup and energy storage : Uninterruptible Power Supplies (UPS), passive energy storage (standard- and ultra-capacitors), chemical energy storage (batteries and advanced chemistry systems), and kinetic energy storage;
Advanced technologies : Solar photovoltaic power converters and microgenerators;
Environmental standards : Reducing the world’s power consumption of electronic devices in their off state, as well as increasing their power supply conversion efficiency, could potentially save tens of tera-watt hours (1012 watt-hours), which could relieve the earth’s atmosphere of tens of mega-tons of CO 2 each year and other undesirable power generation chemical byproducts. Power supply manufacturers will be available to discuss worldwide environmental standards including Energy Star, International Energy Star, Blue Angel, the Group for Energy Efficient Appliances, the European Code of Conduct, EU Eco Label, Energy Plus, and Nordic Star;
High-performance solar photovoltaic electronics : The market for photovoltaics is currently growing between 30 and 50%. In 2007, 3-4 gigawatts (GW) of solar system capacity were installed, increasing the total worldwide installed system capacity to 10 GW;
ICs : Approximately 40 commercial IC types are used to convert solar photovoltaic energy into line power. IC switching frequencies ranges from low (50 Hz or 60 Hz) to high (16 kHz to 100 kHz);
Energy harvesting: Microgenerators or energy scavengers can generate energy from light, sound, temperature differences, or vibrations to replace or supplement batteries. Future energy scavengers will charge mobile phones as people walk, drive heart pacemakers through the beating of the heart, or feed waste heat and engine vibrations to air conditioning systems or other electronics in automobiles;
Hybrid automobiles : Development trends in primary and rechargeable batteries, as well as related charging technologies, will be featured. The 2009 Mercedes S 400 Hybrid luxury limousine sets a new standard with a lithium ion battery in an automobile application; and
Medical power supplies : Medical power supplies must be efficient, compact, quiet, and safe. Supplies must meet higher input-output voltage limits as well as very low ground leakage current. Required cooling airflow must not create fan acoustic noise.
As the large power supply market grows, IMS Research predicts an annual growth rate of 10% for power supply ICs during the next five years. Rising demand for consumer electronics, increasingly complex power management systems design, and growing interest in energy-efficient products will bring the world market for voltage-regulating systems to a volume of $15 billion by 2011.
