  \section{Introduction}
+ Wireless sensors networks (WSN) are currently emerging as solutions to monitor 
+ and collect data in situations where traditional ``wired'' sensing components 
+ are cumbersome or impractical.  Though originally developed in the late 1990's 
+ for the military to monitor hostile combat situations, scientists and experts 
+ now see applications in monitoring structural conditions in large skyscrapers 
+ or bridges, industrial manufacturing operations, heating and cooling systems, 
+ and an endless addition of other applications.  The technology, however, is 
+ extremely early in its lifecycle -- where commercial markets are minute and 
+ the bulk of the current customers are comprised of government, academic, and
+ corporate researchers.  >>NEED SOURCE REFERENCE<<
+ 
+ These researchers are continually developing and optimizing WSN for use in 
+ untracked territory (often literally) >>reference great duck and firebug papers <<, 
+ and require hardware that can repeatedly be rapidly deployed, operated, and 
+ then taken down for constant revision.  Because of the nascence of the 
+ technology, there are no commercially available housings or chassis units 
+ available that serve as the ``AT computer case'' of wireless sensor hardware.
+ 
+ We are developing a mechanical chassis for wireless sensor network equipment 
+ distributed by Crossbow Inc.  The chassis will allow for rapid assembly, 
+ deployment, and dissasembly of the Crossbow WSN hardware.
+ 
+ This paper reviews the design process and technical issues for creating such a chassis.
+ 
+ \section{Hardware Overview}
+ -Components overview
+ -sensing
+ -mote board
+ --radio antenna
+ -power
+ 
+ Discuss issues that stem from interconnections and assembly.
+ 
+ \section{Design Objectives}
+ Discuss needs for the following features:
+ -Tool-less; requires only hands and possibly a coin to open, disassemble, reassemble (rapid and simple)
+ -Separation of modular components: sensing, power, mote, antennas
+ -Wiring harness to separate power connection
+ -battery cage design to accommodate different battery candidates
+ -Supports mounting by: screw, strap, zip-tie, magnet
+ -Injection moldable for low-cost production
