\subsubsection{Servicability of Collars} \subsubsection{Servicability of Collars}
Because the collars are intended to be battery-based, they will need to be serviced,
with the minimum goal of replacing or recharging the on-board batteries. This
must be possible to people with no prior technical experience, as the presence
of such experience is not guaranteed the expected client base. Other common
servicing goals, such as cleaning the device, should also be easy to accomplish
without an understanding of the architecture or implementation of the FGC system.

\subsubsection{Battery Efficiency}
Since the FGC device is battery powered and will require maintenance upon
reaching low battery levels, it's important that the device is able to
maintain an operational level of charge for long periods of time. That
is, the number and duration of servicing actions should be low, in alignment
with the original goal of reducing human labor. At minimum, the device
should remain operational for 7 days (1 week).
\subsubsection{Support for Multiple Collars}
As mentioned above, the goal for hte FGC system is to support large herds of animals,
which normally require significant portions of time to be dedicated by humans.
In order to properly support large herds, it must be possible for the system
to support as many as 100 concurrently active collars without issue. This
requirement applies to the collars themselves and the Android application:
\begin{itemize}
\item The collars themselves should not experience difficulties when concentrated
in large groups (farm animals instinctively tend towards proximity).
\item The Android application, given hardware that is not greatly outdated,
should be able to display and manage this number of collars without
additional delays.
\end{itemize}

Besides the "standard" operational mode for the collar, it
is useful to envision other modes that help in troubleshooting
and setting up the FGC system. We define the following modes:
\subsubsection{Standard}
In this mode, the device uses the defined
"out of bounds" area to determine whether or not to emit a negative
stimulus. The produced negative stimuli are as defined in the
sounds and electrical shock section of the functional requirements.
\subsubsection{Electric Shock Test}
In this mode, the device operates identically to the standard mode
described above, with the exception of not generating electrical
shocks. Instead, the device should emit a different sound (or
a visual signal) to indicate when the shock would have been delivered.
This allows for safe testing of the device's behavior around area boundaries.

\subsubsection{Weight}
It's necessary for the device to be physically bearable by livestock for indefinite
periods of time. If the resulting collar is a constant and noticable weight on the
farm animal, it would serve as an unnecessary and permanent source of stress. Besides
the ethical considerations of subjecting an animal to a constant level of stress through
unnecessary physical labor (i.e. carrying a collar that is too heavy), this goes against
the purpose of the project, since it will likely reduce the quality of the resulting animal
management below the level that can be provided by humans.
\subsubsection{Form Factor}
In order to be able to effectively use the collar, it must fit comfortably on target farm
animals. In our initial prototype, these animals will be cows, and thus, a requirement
for the project is that the collar can be put onto, and stay on a farm cow.

\subsubsection{Water Resistance}
The product will be tested in collaboration with Oregon State University's College of Animal
Science, and therefore, will be tested in Oregon's climate. Since rain is very common
during the winter months in Western Oregon, the device must be readily able to withstand
such conditions, without sustaining any damage.
