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. \subsection{Performance requirements} +\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 + \item The Android application, given hardware that is not greatly outdated, + should be able to display and manage this number of collars without + additional delays.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} + \subsection{System interface} +\subsubsection{LoRa} +@ryan \todo{write this} + \subsection{System operations} \subsection{System modes and states} +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. + \subsection{Physical characteristics} +\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. + \subsection{Environmental conditions} +\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. + +\todo{Anything else?} + \subsection{System security} +\todo{Do we need this?} \subsection{Information management} +\todo{Do we need this?} \subsection{Policies and regulations} +\todo{Do we need this?} \subsection{System life cycle sustainment} +\todo{Do we need this?} \subsection{Packaging, handling, shipping and transportation} +\todo{Do we need this?} \section{Verification} +\todo{Someone else please} \end{document}
