Abstract Regular service of the vehicle is to be done with high precision service equipment, to ensure the factory performance of the vehicle over the entire life of product usage. However, complex nature of the physical processes involved in the service of the vehicle subsystems makes it costly for optimizing the service equipment performance for entire range of operation. Air-conditioning service (ACS) equipment is one such product in the diagnostics domain which deals with compressible, transient and two phase flow in open loop systems. Development of control system for the service equipment to perform optimally over the entire operational range requires accurate mathematical model of the system under study. Application of mathematical model based approach requires calculation of geometrical details, environment information and fluid properties during the process for estimating the process behavior.
Procedure for Certification that Requirements for Mobile Air Conditioning System Components, Service Equipment, and Service Technician Training Meet SAE J Standards
This SAE Standard provides manufacturers, testing facilities and providers of technician training with a procedure for certifying compliance with the appropriate standards. Manufacturers or seller who advertise their products as Certified to an SAE J standard shall follow this procedure. Certification of a product is voluntary; however, this certification process is mandatory for those advertising meeting SAE Standard(s) requirements. Only certifying to this standard allows those claiming compliance to advertise that their product (unit), component, or service meets all requirements of the specific SAE standard. Certification of compliance to this and the appropriate standard and use of the SAE label on the product shall only be permitted after all the required information has been submitted to SAE International and it has been posted on the SAE web site.

This guide clearly defines the purpose, goals, and objectives of an IBR. It also describes the attributes of an effective IBR and discusses a baseline review process that will lead to a better understanding of program risks. It provides a common definition and framework for the IBR Process. This process harmonizes, and to the extent possible, unifies the management objectives for all PMs. The IBR Process enables managers to effectively utilize the project Performance Measurement Baseline (PMB) to assess performance, and to better understand inherent risks. The IBR Process should continue throughout the life of a project.
Abstract Alongside with the increasing vehicle complexity, the functionalities related to the safety, diagnosis and maintainability have become critical. The operators of special machines such as agricultural, mining, construction vehicles might be overwhelmed by this increased complexity and, as a result, operations for the recovery or maintenance of their vehicles become difficult. The Augmented Reality (AR) seems to be a very promising technology both if applied to traditional smart-phones or to the upcoming glasses, that has been just presented to the market by several manufacturers. This paper reviews some use cases of applications created in Institute for Agricultural and Earthmoving Machines (IMAMOTER) of the National research Council of Italy (CNR) engineers laboratories, which propose a novel approach for assisted maintenance, recovery or training.

This ARP also serves as a concise reference of considerations, approaches, activities, and requirements for producing the end-to-end engine health monitoring system comprised of both on and off-board subsystems for the sensing, acquisition, analysis, detection, and data handling functions of an EHMS. These functions and related maintenance activities promote engine safety. These functions may also be used to effect continued operation or return to service decisions when demonstrated as compliant with the applicable airworthiness requirements defined by the responsible Aviation Authority. Where practical, this document delineates between military and commercial practices.
