1. SCOPE

This specification defines the requirements for a family of components that provide data and power distribution for body worn devices. The goal of these components is to minimize complexity, reduce parts counts, reduce size, weight, cost, and reliably provide Soldiers and Marines with flexibility and ease for mission operations. This specification is written in conformance with MIL-STD-961E Change 1, Military Standard:

Defense and Program-Unique Specifications Format and Content. Performance requirements are listed in Section 3 with the corresponding verification criteria in Section 4. Future devices or integration of capabilities would be addressed as needed to enable needed functionality. This could include embedding or having a PAN interface to a dongle for capabilities like Intra-Soldier Wireless (ISW). The Indefinite Delivery/Indefinite Quantity (IDIQ) contract could be updated to allow new models and upgrades to the NGH.

1.1 Background

Nett Warrior (NW) is a Soldier worn system that supports the mission of the dismounted combat Leader. The End User Device (EUD) provides computer processing, data storage, user display, and navigation functions while operating as the Universal Serial Bus (USB) Host. The Next Generation Hub (NGH) facilitates data exchange between the EUD and other peripherals. The NGH also provides power distribution from a common power source. This concept is illustrated in Figure 1 below.

Figure 1 – NGH Interconnect Block Diagram

Multiple NGH devices may be “daisy chained” to facilitate connection of additional equipment as shown in Figure 2 – “Daisy Chained” Hubs below.

Figure 2 – “Daisy Chained” Hubs

1.2 Item Description

1.2.1 NGH

The NGH functions as a USB 2.0 hub for data communication among devices. It also distributes power from two power input ports to provide Person Area Network (PAN) power to connected devices.

4.0 VERIFICATION

4.1 General Information

This section establishes the verification requirements to verify the Section 3 requirements. The verification methods shall be those shown in the Verification Cross Reference Matrix, TABLE VI: Verification Methods Table, and as described in the associated paragraphs of this section.

4.1.1 Classification of Verification

Classifications of Verifications are as follows:

Production Qualification Test (PQT)

Quality Surveillance Test

Government Test (Developmental and Operational)

The SOW guidance shall cover whether the PQT is a first article sample, a first production item, or the number of test items. These documents shall also include specific instructions regarding arrangements for examinations, approval of first article test results, and disposition of first articles.

4.1.2 Methods of Verification

Verification methods are provided in the table below.

TABLE VI: Verification Methods Table

Method Description

Analysis Involves a technical evaluation of design information such as equations, charts, graphs, drawings, schematics, and other data. If actual tests were conducted for a related or unrelated purpose, and utilization of these data will prove that requirement has been met, it should be considered “analysis”. Analysis methods include the use of modeling and simulation with a government-accredited model.

Demonstration Observable functional operation, under controlled conditions not requiring subsequent analysis of data, is used to verify that a given requirement is met.

Examination An element of verification and inspection consisting of investigation, without the use of special laboratory appliances or procedures, of items to determine conformance to those specified requirements which can be determined by such investigations. Examination is generally nondestructive, and typically includes the use of sight, hearing, smell, touch, and taste; simple physical manipulation;

mechanical and electrical gauging and measurement; and other forms of investigation.

Test Involves observation or recording of data during operation of an item. Where “test” is the designated verification method, it is understood that some degree of analysis is inherent in the verification process and need not be so identified on the verification cross-reference matrix.

4.1.3 Basis for Verification

The failure of any assembly, device, component, or test specimen to meet any of the verification criteria shall be cause for rejection. The Government may issue a waiver to accept products “as is” or terminate verification activities upon any failure to meet any of the requirements. The NGH is expected to meet all verifications as noted in TABLE VII.
