Product Code:SAE J1472
Title:Braking Performance--Roller Compactors
Issuing Committee:Optc2, Braking
Scope:This SAE Standard specifies brake system performance and test criteria to enable uniform evaluation of the braking capability of self-propelled, ride-on vibratory steel wheel, static steel wheel, and rubber-tire roller compactors with maximum level surface machine speeds of 25 km/h or less. Service, secondary, and parking brakes are included. Machines with maximum level surface machine speeds greater than 25 km/h shall conform to the requirements of SAE J/ISO 3450.

Title:Bluetooth Wireless Protocol for Automotive Applications
Issuing Committee:Vehicle Architecture For Data Communications Standards
Scope: This SAE Information Report defines the functionality of typical Bluetooth applications used for remotely accessing in-vehicle automotive installations of electronic devices. Remote access may be achieved directly with on-board Bluetooth modules, or indirectly via a custom designed gateway that communicates with Bluetooth and non-Bluetooth modules alike.Access to the vehicle, in the form of two-way communications, may be made via a single master port, or via multiple ports on the vehicle. The Bluetooth technology may also be used in conjunction with other types of off-board wireless technology.This report recommends using a message strategy that is already defined in one or more of the documents listed in 2.1.1, 2.1.4, 2.1.5, and 2.1.6. Those strategies may be used for some of the typical remote communications with a vehicle. It is recognized, however, that there may be specific applications requiring a unique message strategy or structure.This document depicts five different levels of security measures that may be required for the various types of communication.The EMC test requirements for the implementation of this protocol are recommended.This report makes no attempt to define all of the applications wherein the Bluetooth protocol may be utilized. A number of use cases are listed in Section B.1 of the appendix to serve as representative applications, e.g., credit card transactions, vehicle diagnostics, toll booth collection, flash reprogramming, etc.
