RedXDefense produces the XPAK, a portable trace explosives
detection system. The iModule adds the capability to log and
map sampling locations. When samples are taken, the iModule
stores the location plus the sample intensity (low, medium,
high). This data may be uploaded to a PC using an SD Card or
a USB port, and superimposed on a map to indicate possible
“hot spots” of activity.
The iModule was designed under intense time pressure, with
60 production units delivered to the client within 6 weeks
after the start of the project. An additional 40 units were
delivered less than three weeks later.
Additional information about the XPAK may be found on
RedXDefense’s website. |

System
Overview
The iModule consists of:
- GPS (Global Positioning System) module to determine
location.
- Removable SD Card to hold samples and to allow
firmware updates.
- USB port for communication to a PC
- Miniature scanner to read the bar code of the sample
bag.
- Battery power supplies, with low-battery sensing and
battery protection circuit
- Low-power microcomputer, switches and status LEDs
Project Scope
Bolton Engineering worked with RedXDefense to create a
specification, designed the schematics and circuit
board, wrote all test and embedded firmware, fabricated
and debugged the hardware. RedXDefense was responsible
for all mechanical and industrial design, and wrote all
PC-resident software. The project was completed in six
weeks, on time for a scheduled customer delivery. The
first-pass boards worked and fit perfectly without
requiring changes.
