Use of airborne high resolution digital sensor imagery is ever increasing. Color HDTV, infrared cameras and radar are examples of such sensors. And they are becoming increasingly used for mission purposes by the military, police, customs and coast guard onboard helicopters and fixed wing aircraft. These users have requirements for onboard presentation, analysis and storage. Use of weather radars and other similar types of sensors are flight oriented applications in major types of aircraft. Another application is the integration of cockpit and cabin surveillance systems onboard commercial airlines. Cabin surveillance systems, growing from cockpit door cameras to complete cabin surveillance, will use several cameras. The purpose is to acquire and store imagery from un-normal events including unruly passengers and eventual terrorists. The primary intentions are security awareness in the cockpit as well as collecting evidence for a potential prosecution.
The growing need for an efficient worldwide airspace system management, generated by an increasing traffic load, requires new capabilities for air-ground data communication technologies. In order to cope with these requirements, the Federal Aviation Administration (FAA), EUROCONTROL, and the International Civil Aviation Organization (ICAO) have jointly made specific recommendations for candidate technologies for the airport surface communication network. In the SESAR project, the Aeronautical Mobile Airport Communication System (AeroMACS) technology is being developed in such a way to provide next generation broadband and wireless data communications for airport surface applications (i.e. Air Traffic Control ? ATC, Airline Operational Communications ? AOC, and surface vehicles services).
Spotlight on Design: Insight features an in-depth look at the latest technology breakthroughs impacting mobility. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. Automated driving is made possible through the data acquisition and processing of many different kinds of sensors working in unison. Sensors, cameras, radar, and lidar must work cohesively together to safely provide automated features. In the episode Automated Vehicles: Converging Sensor Data (8:01), engineers from IAV Automotive Engineering discuss the challenges associated with the sensor data fusion, and one of Continental North Americas technical teams demonstrate how sensors, radars, and safety systems converge to enable higher levels of automated driving.
ISO 26262 is the first comprehensive automotive safety standard that addresses the safety of the growing number of electric/electronic and software intensive features in today's road vehicles. This paper assesses the standard's ability to provide safety assurance. The strengths of the standard are: (1) emphasizing safety management and safety culture; (2) prescribing a system engineering development process; (3) setting up a framework for hazard elimination early in the design process; (4) disassociating system safety risk assessment from component probabilistic failure rate. The third and fourth strengths are noteworthy departure from the philosophy of IEC61508. This standard has taken much-needed and very positive steps towards ensuring the functional safety of the modern road vehicles. SAE publications from industry show a lot of enthusiasm towards this standard.
The ISO 26262, titled "Road vehicles - Functional safety," is a Functional Safety standard that gives a guidance to reduce the risks to tolerable level by providing feasible requirements and processes. This standard is an adaptation of the Functional Safety standard IEC 61508 for Automotive Electrical/Electronic and programmable electronic Systems. The standard covers the development of safety-related electrical, electronic and programmable electronics systems in the road vehicles. It will have a significant impact on the way such systems are designed, developed, integrated and validated for safety. Functional safety of embedded systems has become an integral part in automotive engineering activities due to the recently released safety standard ISO 26262. One main challenge is to perform development activities compliant to the standard and provide the respective documentation.

The front luminous vacuum fluorescent display (FLVFD) technology is a variation of the conventional vacuum fluorescent display technology. Having first been introduced into the consumer electronics market in 1983, FLVFD has seen increasing usage. FLVFD today offers improvements in the areas of visibility, viewing angle, package efficiency, operating temperature, and life. Although vacuum fluorescent displays have been utilized in automotive applications for more than ten years, the front luminous technology has not been used. The main reason for FLVFD's absence has been the highly reflective surface that the internal aluminum wiring forms on the front glass under direct sunlight conditions. This paper will discuss the studies and evaluations which have taken place to eliminate the reflection problem through the use of an optical multi-layer thin film process. This study assures the feasibility of using the FLVFD technology within the automotive environment.
Historically, the prime application of mobile radio has been to provide a "stand-alone" two way voice communication link between a base station operator and the vehicle. More recently however, the application of modern computer technology has made the integration of the mobile radio system in the total fleet management system, a practical proposition resulting in increased flexibility, improved operational effectiveness and provision of features and facilities that were not available before. To illustrate these developments, this paper describes a large transport control system, which is designed to manage a fleet of up to 2,000 vehicles. This is achieved using a computer control graphics display system in the fleet operations centre which is linked to the vehicle by high speed digital radio data transmission. In addition, a highly accurate automatic vehicle location/monitoring facility which is an integral part of the system, greatly enhances the operational capabilities.
As a result of progress in electronics technology, more and more automobiles have been equipped with various types of electronic control subsystems incorporating low-priced, flexible and multi- functional microprocessors. This paper reports and analyzes the current status of electronic control devices, and further discusses, from six separate aspects, those trends affecting electronic control devices likely to be seen in the near future as a result of further progress in electronics technology.
Polar orbit extravehicular activity (EVA) will expose EVA equipment to the conditions in which charging of Defense Meteorological Satellite Program (DMSP) satellites has been measured. Charging can occur when you have darkness, incident energetic electrons, and low neutralizing plasma density. Fluxes of precipitating keV to tens-of keV electrons, which also cause optical auroras, may be encountered in the high latitude auroral zone. In addition, a large body such as the Shuttle sweeps out the ambient ionospheric plasma to produce a cavity in its wake. Laboratory test results will be presented that confirm charging and subsequent arc discharge of EVA equipment material samples. Induced current and radiated radio frequency electromagnetic interference (EMI) were measured from the arc discharges. Such EMI could cause potentially dangerous EVA equipment anomalies. Ground tests of subsystems and the complete EVA equipment system are needed.
Grumman developed, patented, and tested a heat pipe concept to increase the power dissipation capability of the SEM FORMAT B Standard Module. The systems integration concept approach in the development of the design was to: Provide a heat pipe module within the existing SEM FORMAT B form factor that would be interchangeable with the existing conduction module Utilize the short conduction path of the module Maintain the existing component mounting area Maintain thermal compatibility between the module and heat sink interface. Within the restraints of these objectives, the Grumman concept was shown to be feasible and proven to be capable of providing a power dissipation capability twice that of the existing conduction module.
A technique for measuring and predicting radio frequency interference has been developed which can quantify an individual component’s performance, The assessment of a quantitative performance objective for each component provides a means to acheive a desired level of noise rejection for the system independant of environmental variances.
