      With the cost of microprocessor systems dropping steadily, sensor networks are becoming more and more viable for replacing traditional "dumb" sensors. This presents a host of advantages to the system collecting data, and allows for unprecedented system flexibility. In parallel to these developments, RFID "tagging" has come a long way and has also entered the realm of affordable sensor solutions. The merger of these ideas enables transient, modular, and reconfigurable asset identification and tracking systems. In this paper, we explore the feasibility of implementing such a network with commercial off-the-shelf (COTS) parts for real world applications. Specifically, we create a drop-in system for managing documents and records in a medical triage center, based on identifying assets and personnel by means of RFID. A self-reconfiguring sensor network provides the foundation, allows for the system to be deployed in minutes, both on a battlefield or in a hospital, and once deployed, the hospital beds may move around freely. The advantages of this platform will be discussed alongside the unique requirements that are introduced in this type of project.

      NASA's Remote Imaging System Acquisition (RISA) project has the goal of producing a single robust and space-efficient imaging system. This paper will show the progress of the current RISA project iteration, tasked with implementing a Inter-Integrated Circuit (I²C) communications controller on a radiation hardened Field Programmable Gate Array (FPGA), characterizing a liquid lens optical system, and adding a radiation hardened temperature sensor. The optical design focuses on small liquid lenses that can vary focal length with no moving parts. The chosen designs will allow this camera system to meet critical mission objectives and provide reliable service to NASA's astronauts.
    • A Telemetry System for Firefighters

      In this project, a telemetry system is implemented to save firefighters from potential danger in their working environment. Each Firefighter has a "node" or "unit" attached to them which contains temperature, oxygen, and carbon-monoxide sensors, and a transceiver. Each node constantly transmits data collected by the sensors to a central "base station." The base station consists of a laptop which is monitored by the Fire Chief at a safe distance from the scene, and it displays gas levels. The base station monitors the sensor readings, and sets off an alarm locally and also at the node if a reading has reached a predetermined critical value.
