摘要:
Systems and methods are provided for intelligently establishing a communication session between a machine and off-board system. In one implementation, a system for intelligently establishes a communication session. The system includes a machine communicating with a network and an off-board system that transmits a request for data from the machine over the network. The system also includes a communication server in communication with the machine and the off-board system via the network. The communication server determines whether hardware and a network connection to transmit the requested data and are available on-board the machine and determines whether the off-board system has authority to receive the requested data.

A software system development apparatus is provided. The software system development apparatus may include a processor and a computer-readable medium operatively coupled to the processor. The apparatus may also include a system design tool program stored on the computer-readable medium that, when executed by the processor, is operable to regulate user access to at least one aspect of the system design tool according to one or more authorization categories of users of the system design tool. The system design tool may also be operable to generate a real-time embedded control software system by selecting from a collection of reusable software components stored and described in a catalog in accordance with the Reusable Asset Specification (RAS).

A communication system is disclosed for communicating data among a plurality of electronic modules. The communication system may include a data type classifier configured to separate the data into information-type data and signal-type data. The communication system may further include a first communication stack configured to communicate the information-type data among the plurality of electronic modules. The communication system may also include a second communication stack configured to communicate the signal-type data among the plurality of electronic modules. The first communication stack and the second communication stack may share a physical data link.

摘要:
An apparatus (10) for use on electronically controlled fuel injection systems senses speed, angular position, and direction of rotation using only a single Hall effect type sensor (24). A disk element (14) is fixedly connected to and rotatable with the camshaft of an internal combustion engine. The disk element (14) includes a plurality of circumferential zones (16a-16x) of substantially identical length with each zone (16a-16x) having first (18a-18x) and second (20a-20x) areas. A first portion 16c-16t, 16v-16x) of these circumferential zones (16a-16x) have first (18c-18t, 18v-18x) and second areas (20c-20t, 20v-20x) which are substantially different in length than the first (18a, 18b, 18u) and second areas (20a, 20b, 20u) of a second portion ( 16a, 16b, 16u) of the circumferential zones (16a-16x). Accordingly, the sensor (24) delivers a signal which has a frequency directly related to the instantaneous velocity of the disk element (14), but varies in pulse width in response to the first (16c-16t, 16v-16x) and second (16a, 16b, 16u) portions of the circumferential zones (16a-16x). A microprocessor (46) operating under software control detects the instantaneous angular position and direction of rotation of the disk element (14) by locating the second portion (16a, 16b, 16u) of the circumferential zones (16a-16x) and the order in which they are received.
