  **STATEMENT
OF WORK (SOW)**
  **MEDIS
TECHNOLOGIES/MORE ENERGY**
  **Wearable
Computer Power**
  **1.0**
    **OBJECTIVE**
  Medis
Technologies/More Energy (hereinafter “Subcontractor”) shall conduct and support
the activities that are defined herein for the purpose of improving the overall
effectiveness of Information Warfare (IW) operations through the use of its
advanced fuel cell power technology.
  **1.1**
    **General**
  The
Special Operation Forces (SOF) of the U.S. Department of Defense (DoD) require
computer assets and associated peripheral devices that are rugged, lightweight
and can provide an electrical power life of at least 8 hours. DoD’s target
device will be durable (MIL-STD-810), fully compliant with Electromagnetic
Interference (EMI) emissions (MIL-STD-461) and have a total load out weight of
less than 4 pounds.
  As an
initial step toward achieving DoD objectives, the primary focus of this project
is to demonstrate operation of a modified commercial off the shelf (COTS) tablet
when powered by an external fuel cell power system. Ten of the modified COTS
tablets with five fuel cells, both of which are recognized to be prototypes,
will be delivered to the Government in month 12 of the program for preliminary
test and evaluation. Program progress and results will be documented in monthly
reports and summarized in a Final Report to be submitted to the Government
in **[Subject to a request for confidential treatment; seperately
filed with the Commission]**.
  The
desired result of this project is to demonstrate that the deliverable prototypes
are capable of continuing on a realistic spiral development path that will meet
the “wearable device” criteria established by the Special Tactics and Tactical
Air Control Party (TACP).
  **2.0**
    **TECHNICAL
      REQUIREMENTS**
  The
Subcontractor shall provide support in accordance with the following
paragraphs.
  **2.1**
    **Technical
      Approach**
  This
project is focused on evaluating and implementing to the extent practical
potential advancements in wearable computing solutions. Higher volumetric
electrical energy density will be sought to extend computer run time and
potentially reduce logistics support in field operations.
  **2.1.1**
    **Advanced
      Power Source**
  The
subcontractor shall provide a fuel cell power pack and refueling system suitable
to extend the battery life of the **[Subject to a request for confidential

      Power Pack
  ·
    Capable
      of supporting electronic indication when fuel cell refueling is
      necessary.
  ·
    Minimum
      of **[Subject to a request for confidential treatment; seperately

      designed by **[Subject to a request for confidential treatment;
      seperately filed with the Commission]** and interface with Medis’
      fuel cell power pack system.
  ·
    A
      refueling cartridge capable of replacing fuel and
    electrolyte.
  ·
    Acceptance
      test to be demonstrated with an **[Subject to a request for
      confidential treatment; seperately filed with the Commission]**Watt resistive load and the Medis fuel cell power pack system
      must supply a continuous **[Subject to a request for confidential
      treatment; seperately filed with the Commission]**Watt output for
      a duration of 8 hours.
  The
subcontractor will provide a functional check out and evaluation of the
individual power packs and integrated systems.
  **2.1.2**
    **Tablet
      Integration with DLEDS Fuel Cell**
  The COTS
tablet supplier, **[Subject to a request for confidential treatment;
seperately filed with the Commission]**, is responsible for providing a
prototype external fuel cell power management device intended to demonstrate a
functional integrated **[Subject to a request for confidential treatment;
seperately filed with the Commission]**Fuel Cell system. The goal of the
integrated system is to operate continuously for 8 hours and to demonstrate
successful battery recharging capability. The power management module (PMM) will
be an external interface device between the **[Subject to a request for
confidential treatment; seperately filed with the Commission]** and the
fuel cell.
