“…Cook and colleagues (Cook and Sastry, 2005;Cook et al, 2006) describe a systematic method for the selection and design of a power system for a WIMS Environmental Monitor Testbed (EMT). The method focuses on selecting and designing power supplies for microelectronic devices that are prescribed after the design is nearly complete.…”

“…The methods described by Cook and Sastry (2005) and Fu et al (2005) are both interesting solutions to the problems that industrial design engineers face when making a choice for a power source during the concept phase. Most of them are either used by the institute itself (e.g., POWER) or not implemented (e.g., the CES database of power Case D: Selection of Power Sources for Portable Applications sources).…”

New power sources emerge very quickly. Implementation of hybrid power sources for portable electronics depends on the knowledge of industrial designers. For now this group has little understanding of fuel cells and especially fuel-cell hybrids. This slows down implementation and increases the chance of failure.In this paper a review is given of tools and methods which gives concept designers a first guesstimate of the volumes they have to deal with when designing the power source. Second there will be a first approach to a second-order model and method which should produce an optimized volumetric design of the fuel-cell hybrid, being used in concept phase of design.

“…Our concurrent efforts 54 have been in selecting hybrid power supplies, given the present limitations in reducing power spikes in this device. This work comprises selection of hybrid power supply strategy that accounts for both a high power density ͓W/L͔ power source for peaks/spikes in the power profile, and a high specific energy ͓Wh/kg͔ power source for long service.…”

Rapid and reliable assessment of volatile and semivolatile organic compounds in the environment using gas chromatography �GC � is often limited by cost of analysis, and time delays between sampling and analysis. Many environmental monitors incorporating GC systems are too large for portability, and lack sufficient sensitivity and/or selectivity to serve as practical environmental monitors. Frequently, a complete system redesign, due to nonlinear power scaling relative to component size, is required to reduce the mass and volume of power supplies, especially for the micro-systems of present interest. Here, we examined four strategies in reducing power demand by the largest consumer of power in a model micro GC, the preconcentrator. Our simulations included alterations in heater pad placement/size, reduction of thermal mass in the device, vacuum sealing, and incorporation of a gas dwell time during preconcentrator heating. Our numerical results were in general agreement with experimental findings in simpler systems, in terms of the benefits of vacuum sealing. The greatest reductions in power demand were achieved with vacuum sealing �51% � and reductions in thermal mass �15%�. Future work will address structural and materials issues involved in reduction of thermal mass, and also optimization of power supplies required to meet the multilevel power demands of these complex microelectromechanical systems. © 2005 American Vacuum Society. �DOI: 10.1116/1.1886821� I
