Hypothesis: Globally, the quality of life for hundreds of millions of people can/will be substantially improved if there is an international standard for PoE­LPI48 (Power­Over­Ethernet Local Power Infrastructure 48 VDC nominal).
PROBLEM / OPPORTUNITY
SOLUTION
HUMAN IMPACT
Intrinsic low-voltage DC nature of modern technology devices
works with more efficiency and synergy in a low-voltage DC infrastructure.
This includes efficiency and safety working with alternate energy sources.
EPICS – Experimental Physics
and Industrial Control System
What was the projected impact of the Internet?
Beyond the scope of this poster.
Wired networking allows reliable secure Internet of Things (IoT) not possible with wireless.
Wired network cabling can also deliver low-voltage DC power to IoT devices.
Without a doubt, globally, thousands of companies will produce IoT devices and systems,
generally using proprietary network protocols.
The Problem/Opportunity is that there needs to be a Lingua Franca version of a
globally accepted, non-proprietary, top quality, soft real-time control protocol,
so that these thousands of devices/systems can become far greater than the sum of their parts.
This proposal is not for a specific product, but for precipitating an international standard that,
due to its non-proprietary nature, can be accepted as a Lingua Franca soft real-time control protocol.
Such a protocol will enable a global market for devices/systems,
that can operate with or without an operational high-voltage AC mains system.
* Assisted Living (safe & comfortable)
Elderly dementia & mobility; Many other medical conditions
Among the highest of priorities of aging generations is the
desire to live at home as long as possible, despite age related dementia, mobility, etc.
The more items in a home that are networked, the more effective assisted living can be.
* Staying put during weather events (safe & comfortable)
Travel during severe weather can be dangerous for young, healthy people;
for the elderly, in failing health, it can be fatal. With proper preparation, it can be safer to stay put.
Stationary Lead-Acid Battery Backup of:
LED Lighting, Communications,
Low-voltage DC Safe Electric Blankets,
Refrigerators / Freezers (food/medicines),
Microwave Ovens,
Clothes Washing Machines / Dryers
Normal:
great labor savings
Emergency: kilowatt hours of energy
* Numerous small PoE devices: Door/drawer knobs/handles with touch sensing and RGB LEDs
These allow monitoring and assisting elderly folks remembering/locating where things are
* Small PoE devices: Toothbrush holder, soap dish, etc. (hygiene changes are indicators to note)
* A significant PoE-LPI48 device: LPI48 Water Closet for personal hygiene
Smaller version: LPI48 Chamber Pot (portable)
* An ultimate PoE-LPI48 device: LPI48 Granny-Flat on Wheels
Starts out as an electric powered mini-motorhome with a sofa that makes into a bed
Has provisions, communications, hospital bed attachments, etc.
to be able to evolve, over time, into a personal, mobile, hospital room.

While EPICS was developed for “Big Physics”,
due to its highly scalable, distributed architecture,
it can be applied to a limitless set of applications.
EPICS-3-14-12 Base
Base functionality from a 1.5 MB tarball
EPICS Gateway
EPICS PV (Process Variable) aware router,
access, security, aliases, load-leveling, etc.
EPICS State Notation Compiler / Sequencer
Run a coffee maker or a particle accelerator

Power-Over-Ethernet
IEEE-802.3.af/.at (12/24 watts)(RJ-45 connector)
PoE provides an Ethernet network connection
and low-voltage DC (both galvanically isolated)
over a single CAT-5/6 cable.
Devices consuming 24 watts or less will follow
existing PoE standards, using the low-cost RJ-45.
Devices needing more than 24 watts will use a
proposed variant of an existing connector.

CONCLUSIONS
The following are needed:
EIOR – Engineering Innovation OutReach
EDKs (EPICS Developer Kits)
given to all engineering students by
In-Kind Sponsorship of for credit
Class/Research/Innovation projects
Undergraduate students:
EPICS tutorials, examples, skeletons, videos
Graduate students:
Peer reviewed publications
Startup incubation
Adding to student knowledge of EPICS
AND/OR
Implementing prototypes of PoE-LPI48 devices
Prototypes will be provided to School of Architecture
School of Architecture PoE-LPI48
Living Studios/Laboratories
Architecture (Built Environment) students and
faculty will evaluate and collaborate in evolution
of prototypes developed by engineering students
Based on their experience with PoE-LPI48 Living
Studios/Laboratories; Architects, around the world,
will be able to publish how they can implement the
Hypothesis: Globally, the quality of life for
hundreds of millions of people
can/will be substantially improved
if there is an international standard for
PoE -LPI48 (Power-Over-Ethernet
Local Power Infrastructure 48 VDC nominal).
Providing the pull to precipitate that standard.
