Advanced Mobile
integrated Power System (AMPS)
Abstract:-
The purpose of the Advanced Mobile integrated Power System (AMPS) is to rapidly develop a configurable power system capable of supporting electrical power & power management requirements to integrate Vetronics, C4ISR, and embedded simulation capabilities into FCS platforms, including robotic Unmanned Ground Vehicles (UGV).
Introduction
Advanced Mobile integrated Power System
Current Technology Barriers
Limited space and weight for electrical power and energy storage components
Emerging commercial 42 volt components need to be military rugged
Lead acid batteries do not have the energy density to support the vehicle mission
Present electrical systems are energy wasteful and are not controlled to support the vehicle mission
Solutions
Develop 42 volt ruggedized components and systems that are smaller and lighter compared to 28 volt systems
Advanced chemistry batteries and fuel cells
SMART Architecture / components to allow management of dynamic power and graceful degradation
System Benefits
34% cable weight reduction for load circuits carrying higher than 3amps.
20 min @ 4 mph silent operation
80% increase in energy storage density (baseline: lead-acid)
2X increase in battery life (baseline:3yrs lead-acid )
Warfighter Benefits
• Provide silent movement, extending the perception of the dismount soldier
• Increase reconnaissance, surveillance, and target acquisition capabilities by facilitating state of the art electronics usage.
• Decrease logistic burden and combat load due to increased battery life.

Clubs centered around the hobby of modeling have existed since the 1950s. The Armor Modeling and Preservation Society, Inc. was founded in 1993 by armor modelers as a means of promoting the hobby using the 'open system' of contest judging.
AMPS was formed as a membership club to promote the hobby of armor modeling, with bylaws that prevented any officer from deriving their income from the hobby of military vehicle modeling. The club operated without incorporation until early 2007, when it was incorporated as a not-for-profit corporation in the state of New York.
AMPS has several purposes:

AMPS has several purposes:
- The
first is a social function, providing a means for those interested in the
hobby of model military vehicle building (including model figure building as well as diorama building) and restoration
to associate with other hobbyists.
- A
second is educational; AMPS events and publications provide detailed
historical information on actual armored fighting
vehicles,
ordnance, and the history of their usage, as well as providing techniques
for improving scale models, figures and dioramas.
- Finally,
AMPS provides some funding for restoration of actual military vehicles and
makes charitable contributions to morale-building efforts for service
members serving in combat areas (see below).
Structure and membership
The model display area at the 2008 AMPS International convention.
The AMPS bylaws and constitution provide for an Executive Board consisting of a President, First Vice-President, four regional Second Vice Presidents, and a Secretary. Additional non-elected officers include Treasurer, Publications Editor, and Marketing Director/Public Information Officer. The founder and first President of AMPS was Steven "Cookie" Sewell. The second President from 2004-2007 was Paul Roberts; the current President is Danny Egan.
Membership is open to anyone with an interest in the hobby. Annual membership fees are $30 for members in theUnited States, $35 in Canada and $40 in other countries. Almost all members are located in the USA, Canada, the UK and Mexico. Currently, AMPS has just over 800 members.
Local chapters

AMPS members often form local 'chapters' of the society. These local clubs operate as part of AMPS but their local base allow their members to meet (usually monthly) and share hobby skills, materials and references.
Current active AMPS chapters and affiliate chapters include:
Benefits of membership
Membership in AMPS gives the modelers several benefits:
a) Voting rights in the society. AMPS members
vote on officers and thus the direction of the society.
b) Discounted admission to all AMPS shows.
c) Discounted pricing from twenty
armor-modeling-related firms who have partnered with AMPS.
d) Six issues per year of the society
journal, Boresight.
Publications
A sample cover of the AMPS journal,Boresight.
AMPS publishes a semi-monthly journal, Boresight. Articles in Boresight are written by the members, and the publication itself is edited by volunteers. The journal typically provides several articles on real armored vehicles for reference purposes, along with modeling articles and how-to guides. AMPS accepts advertising in Boresight as a means of providing discounted hobby products to its members. From the foundation of AMPS in 1993 until 2007, most issues of Boresight were 24 pages in length. Recently the publication has grown to 32 to 36 pages for most issues, with the recent "Stryker Special" coming in at 40 pages and the "Halftrack Special" at 44 pages.
Events
The "Judging Pit" in which model entries are evaluated; this example is at the AMPS 2006 International Convention

The major event hosted by AMPS is the annual International Convention, held each April. This three-day show brings together hundreds of members and non-members to view models, participate in a model contest, buy hobby products, view actual military vehicles, and attend seminars. Recent international conventions have included over 500 scale models on display. The most recent international show was held in April 2010 at the World War II Victory Museum in Auburn, Indiana. This modern venue offers over 150 actual historic military vehicles. Seminar speakers include tank crew veterans, well-known modelers and researchers, and industry representatives from firms such as Tamiya and AFV Club. The 2010 show was the most succeful AMPS show ever with 634 models entered as well as club display tables.
Smaller regional and local contests are also held from time to time, typically attracting less than 200 scale models for single-day events.
AMPS East is an East Coast USA show, held annually since 1999, normally in the western Connecticut (in recent years) or northern New Jersey (formerly) area.
AMPS Centex is a midwest show held in Austin, Texas every other year.
Kansas City AMPS holds a show every October in Kansas City, Missouri.
AMPS Atlanta held its first show in February 2009.
Central Virginia AMPS has held three regionals in the Richmond, Virginia area
The scale models entered in the contest are judged according to the AMPS Contest Rules, and may be awarded Gold, Silver or Bronze medals. Scale models are judged for accuracy, level of detail, skill in construction, and paint/markings finish. Some of these models take hundreds of hours to complete. Each modeler is provided with a feedback form showing the points given in each area and what areas need to improve. An 'open' system of judging is used in which each model competes against a standard, not against other entries. Thus, instead of 1st, 2nd and 3rd-place medals, awards are given to all models that reach specified cutoff scores. Since participants are not competing against one another, there is no disincentive to the sharing of techniques and ideas.
The feedback provided in these events is a key factor in helping modelers improve. The AMPS system provides formal feedback, giving specific information about what to improve in the model.
Charitable activities
A few of the over 1,500 kits AMPS members have donated to Coalition troops in Iraq.
AMPS recently launched a clearinghouse project to gather donations of plastic model kits and supplies for shipment to United States military personnel deployed to combat areas. Nearly 2000 kits and hundreds of supply items and books have been sent overseas to help morale and alleviate stress and boredom; additional shipments will follow.
