Abstract Micro Hybrid Systems are a premier approach for improving fuel efficiency and reducing emissions, by improving the efficiency of electrical energy generation, storage, distribution and consumption, yet with lower costs associated with development and implementation. However, significant efforts are required while implementing micro hybrid systems, arising out of components like Intelligent Battery Sensor (IBS). IBS provides battery measurements and battery status, and in addition mission critical diagnostic data on a communication line to micro hybrid controller. However, this set of data from IBS is not available instantly after its initialization, as it enters into a lengthy learning phase, where it learns the battery parameters, before it gives the required data on the communication line. This learning period spans from 3 to 8 hours, until the IBS is fully functional and is capable of supporting the system functionalities.

When a truck or bus suffers from a breakdown it is important that the vehicle comes back on the road as soon as possible. In this paper we present a prototype diagnostic decision support system capable of automatically identifying possible causes of a failure and propose recommended actions on how to get the vehicle back on the road as cost efficiently as possible. This troubleshooting system is novel in the way it integrates the remote diagnosis with the workshop diagnosis when providing recommendations. To achieve this integration, a novel planning algorithm has been developed that enables the troubleshooting system to guide the different users (driver, help-desk operator, and mechanic) through the entire troubleshooting process. In this paper we formulate the problem of integrated remote and workshop troubleshooting and present a working prototype that has been implemented to demonstrate all parts of the troubleshooting system.

AIR4899A
The methodology for maximum package size loading is bsed on a mathematical method allowing the calculation of maximum package size tables. This method does not in principal differentiate between bulk loading and cargo system loading. However, some restrictions have to be considered: - Some cargo systems generate pre-determined pallet trajectories. Envelope curves depending on the pallet size and the possible trajectories have to be determined first. - Door geometric limitations (with or without cargo loading system) - Turning limitations due to weight, load geometry and conveyance capability - Securing requirements This document is not intended for airline operational use. It should be used by engineers performing calculations or developing computer programs to produce Maximum Package Size tables specified in AS1825.

AS832G
This SAE Aerospace Standard (AS) establishes the basic requirements for the specification and testing of air/surface (intermodal) 8 ft x 8 ft (2.44 m x 2.44 m) cross-section containers. The basic rquirements for the air/surface (intermodal) container are presented in Sections 3 to 6 while the detailed design requirements are in Appendix A. Appendix B describes the sections of other standards that apply to air/surface containers. Appendix C describes uniformity of test apparatus and methods. These appendices shall be referred to for important supplemental requirements and procedures for this document. AS4041 presents the requirements for air mode general purpose containers. Requirements for containers to be transported by rotary-wing aircraft are excluded from this document. NOTE: The essential basic and detail criteria are identified by use of the key word "shall."

This SAE Aerospace Standard (AS) establishes the basic requirements for the design, construction and testing of air mode 2.44 m x 2.44 (8 ft X 8 ft) cross-section containers. These containers are to be used exclusively in conjunction with the air mode in freighter versions of wide-body commercial transport aircraft. Air mode containers will normally be on aircraft roller conveying systems and/or on similarly equipped ancillary ground handling devices. Similar requirements for air/surface (intermodal) containers are provided in AS832.

AIR4652A
This SAE Aerospace Information Report (AIR) covers handicapped passenger boarding devices used airside to transfer handicapped passengers between the terminal building and the aircraft. It provides an elevating platform to facilitate access to the aircraft; it does not cover devices for in-terminal or streetside transfers, wheelchairs for on-board aircraft or in-terminal usage, or aircraft boarding bridges. However, it should be recognized that for many handicapped passengers, a boarding chair is necessary for the lifting operation and movement to the passenger's seat inside the aircraft cabin. Such wheelchairs are widely used in larger aircraft, and the Federal Aviation Agency has developed a performance specification for a boarding chair for commuter aircraft.

GEIAHB0007B
This handbook is intended to provide additional information on the use and tailoring of the data in GEIA-STD-0007. The standard provides a new approach to Logistics Support Analysis Record (LSAR) (i.e., MIL-STD-1388-2B) data with emphasis on data transfer (e.g., XML Schemas) versus data storage (e.g., relational tables). GEIA-STD-0007 identifies the range of logistics product data that is generated during the development and acquisition of a system or end item. It does not prescribe the supportability analyses required to generate logistics product data. How the data is generated via analysis techniques/tools, how it is stored and processed, and how the data is used to generate specific logistics support products, is left to the performing activity. GEIA-STD-0007 is a data transfer standard implementing the logistics data concepts of GEIA-STD-927, Common Data Schema for Complex Systems.
