Project Overview / MIssion Objectives

The Bloodhound Tracking Device (BTD) is a patented, non-invasive tracking and sensing system built to deliver real-time intelligence for global cargo. Designed for environments where line-of-sight tracking fails, BTD uses a proprietary Disruption Tolerant Network (DTN) and mesh communications to maintain visibility deep within container stacks—where traditional GPS or satellite systems can’t reach.

But Bloodhound is more than logistics. It’s also a tool for humanitarian intervention. Equipped with advanced sensors capable of detecting life signs, internal movement, sound, and air quality, BTD can identify when a person has been placed inside a container—enabling rapid alerts and potential rescue in cases of human trafficking or smuggling.

From safeguarding vaccines to saving lives, the mission was simple: build a tracking system that works when and where others fail.

Roles and Responsibilities

As the System Architect and Electrical Integration Lead, I was instrumental in the development of BTD’s hardware and communication systems. My responsibilities included:

  • Designing the electrical architecture to integrate various sensors and communication modules within a compact form factor.

  • Implementing the power management system to ensure long-term, maintenance-free operation.

  • Developing the interface between the internal instrumentation unit (IU) and the external communication unit (CU), facilitating seamless data transmission.

  • Collaborating with software teams to ensure reliable data processing and user interface functionality.

  • Conducting rigorous testing to validate system performance under various environmental conditions.

Legacy

BTD has redefined what’s possible in cargo monitoring, security, and humanitarian tech. Deployed globally, it not only provides unprecedented visibility into the status of high-value cargo, but also has the potential to disrupt human trafficking networks by detecting unauthorized human presence inside containers.

This project proved that with the right engineering focus, even a small embedded system can have a life-saving impact. My work on BTD remains one of the most meaningful blends of technical precision and moral purpose in my career.

Highlight: Human Detection in Remote Cargo Scenarios

A standout capability of the Bloodhound system is its ability to detect human presence in sealed, mobile environments—a critical feature in combating human trafficking and smuggling.

I led the integration of multiple sensor systems—including acoustic, air quality, vibration, and thermal inputs—to develop a detection suite capable of flagging the presence of people hidden in containers.

Key challenges solved included:

  • Filtering out false positives from vibration and container movement

  • Ensuring signal integrity through metal walls and RF interference

  • Designing alert logic that could trigger remote action or inspection without requiring constant monitoring

  • Preserving battery life while enabling responsive environmental sensing

This was engineering not just for performance—but for human dignity and rescue.
