>I'm disclosing a list containing the details of 6,681 organizations that applied for contracts with the US Department of Homeland Security. This data was taken from the Office of Industry Partnership at https://oip.dhs.gov.

Contrary to the title this doesn't seem like all contractors? 6681 contractors in total seems a bit low for an agency as big as DHS.

What sort of US government organization hides its contractors?

"The human body is a near perfect energy generator. Demand for energy harvesting innovation, along with technology advances in thin film thermoelectric generators and highly efficient DC/DC boost circuitry now place wearable thermoelectric power harvesting within reach. The objective of Perpetua`s Phase II proposal is to deliver an energy harvesting system for first responder applications powered by the human body. Building on Perpetua`s successful demonstration of wearable thermoelectric generators in Phase I, this proposal combines advances in wearable thermoelectric generators, power electronics, ultra low power transceivers, and physiological sensors integrated into a first responder jacket. In collaboration with emergency response personnel, Perpetua will field test the developed jackets. Building on several decades of experience with thermoelectric generators, system design and product integration, Perpetua will architect modular systems for wearable body energy harvesting. Perpetua`s creative approach with best-in-class technology overcomes the traditional obstacles that have prevented energy harvesting from the human body to produce adequate voltage and usable power. Wearable human body thermoelectric generators promise power solutions for autonomous self-powered sensors reducing the weight, size, and limited life of primary battery power. Long life and small dimensions are particularly important and advantageous for sensor systems for the first responder."

Automatically identifying person-based characteristics is helpful in variety of industries for threat detection. The Department of Homeland Security (DHS) is interested in a video analysis tool that can automatically identify and catalog anthropometric characteristics that are important to On-Person Screening in real time. Toyon Research Corporation proposes to tackle this problem by breaking it into main parts to solve. First, the task of initially localizing and describing airline passenger characteristics can be framed as an object detection problem. Second, the task of tracking airline passengers across a video stream once the characteristics have been initially identified can be done through traditional tracking algorithms that have the ability to run in real-time.
