Wireless networks of seismic sensors have proven to be a valuable tool for providing security forces with intrusion alerts
even in densely forested areas. The cost of replenishing the power source is one of the primary obstacles preventing the
widespread use of wireless sensors for passive barrier protection. This paper focuses on making use of energy from
multiple sources to power these sensors. A system comprising of Texas Micropower's (TMP's) energy harvesting device
and Crane Wireless Monitoring Solutions' sensor nodes is described. The energy harvesters are suitable for integration
and for low cost, high volume production. The harvesters are used for powering sensors in Crane's wireless hub and
spoke type sensor network. TMP's energy harvesting methodology is based on adaptive power management circuits that
allow harvesting from multiple sources making them suitable for underground sensing/monitoring applications. The
combined self-powered energy harvesting solutions are expected to be suitable for broad range of defense and industry
applications. Preliminary results have indicated good feasibility to use a single power management solution that allows
multi-source energy harvesting making such systems practical in remote sensing applications.
This paper reviews hardware and software solutions that allow for rapid prototyping of new or modified UGV sensor
designs, mission payloads and functional sub assemblies. We define reconfigurable computing in the context of being
able to place various PMC modules depending upon mission scenarios onto a base SBC (Single Board Computer) or
multiprocessor architectures to achieve maximum scalability. Also addressed are the sensor and computing packaging
aspects and how such payloads could be integrated with unattended acoustic sensor topologies providing a more
complete fused "picture" to decision makers. We review how these modular payloads could be integrated with
unattended ground sensors to collaborate on mission requirements

This paper reviews hardware and software solutions that allow for rapid prototyping of new or modified embedded
avionics sensor designs, mission payloads and functional sub assemblies. We define reconfigurable computing in the
context of being able to place various PMC modules depending upon mission scenarios onto a base SBC (Single Board
Computer). This SBC could be either a distributed or shared memory architecture concept and have either two or four
PPC7447 A/7448 processor clusters. In certain scenarios, various combinations of boards could be combined in order to
provide a heterogeneous computing environment.
