2 Feasibility Statement
The First Responder system is comprised of several integrated hardware components.
The first is a modified helmet. The helmet contains a tympanic thermometer which can be
activated to take temperature measurements at predetermined intervals. This technology is
readily available from several different manufacturers. Optionally, perhaps in response to
calibration and accuracy concerns, a dermal temperature sensor could be substituted. A carotid
pulse can be read using a flexible PZT thin film tactile sensor.1 Hydration is also monitored
either with a directly attached sensor or a cabled sensor located elsewhere on the body depending
on cost, functionality concerns and technology licensing issues. Several existing and developing
technologies provide this functionality2. The helmet will also contain an interface for the “puck”
device through which sensor data is passed out and battery power is supplied to the helmet.
Optionally, processed sensor data could be used by the puck to generate an alarm or alert signal
which would be used by the helmet to generate a visual and/or audio alert signal to the wearer.
Although not part of the core design, ideas for future expansion or parallel development include
the integration of a hands-free infrared imaging camera and built in display. Such a display could
ideally be toggled off or moved out of the way by way of a retractable visor. If determined to be
necessary during the development and testing processes, the helmet could also be supplied with
its own battery and charging circuitry. The primary argument for avoiding this design is the
addition of weight to the helmet.
The second component is what is currently being referred to as the “puck’ device. The primary
function of the puck device is to create a positioning network using radio-frequency and
ultrasonic signals. This design is based on the Dolphin prototype3 system. The puck uses an
algorithm based on signal decay to measure the distance between originating and receiving
pucks, and a second algorithm based on time delay to measure distance via the ultrasonic signal.
This data is packaged into an array or matrix whose maximum size is determined by the
processing limitations and cache memory size of the CPU utilized in the pucks. The packaged
matrix or array is bundled with other sensor data and is transmitted as part of the RF signal. This
data is then ultimately sent via radio-frequency to a tuned RF receiver and converted to a
standard Wi-Fi signal which is disseminated via a standard Wi-Fi router to the various data
collection and display devices (laptops, tablets, etc.…).
The puck should also house an ambient temperature sensor. The device should be battery
powered and as such contain battery charging circuitry. The programming and data retrieval will
be facilitated through a mini-SD port or comparable solution. Each puck should be individually
identifiable on the network and function whether or not it is attached to a helmet.
Also, although not part of the core design, future expansion could allow for collected ultrasound
data to be used in generating a 3-D environmental map.

6 Integration Thread
The hardware integration thread contains the following components:



A minimum of 3 “puck” devices to establish a minimum amount of data for the positioning
algorithm, one helmet to confirm puck to helmet interfacing, and one sensor in order to
generate a piece of simulated biometric data (either temperature or pulse)
The RF receiver RF/Wi-Fi converter to capture the RF data from the puck network and transmit it
to the Wi-Fi Router
One UI device (tablet or laptop) to confirm receipt and display of data captured by the puck
network and associated sensors as well as efficient transmission over the Wi-Fi network
In the software integration thread, the vital parser (and storage) are very similar to the environmental
and thermal image parsers, and as such will serve as a good basis for this functionality. The logic for
determining alert triggering for vital signs mimics the logic for environmental hazard logic and thus the
testing of both is unnecessary. The map parser is significantly more complex, as data coming in will need
to be changed from an array or matrix to a position in 3-space prior to being stored. This functionality is
the most important and basic to the software architecture. Lastly, being able to manipulate the map
(parsing user input) and display data will show what the UI will roughly look like on a deployed version.

7 User Interface Mockups
Below are sketches of the proposed user interface. Features include a scrollable list of firstresponders on the left, a main view screen and two auxiliary view screens on the right. The main
screen is initialized with the map, but clicking on either of the auxiliary screens will bring that to
the main screen, moving the map down. This is a reversible process.
