Can augmented reality reduce "road rage?"

This week’s Question: A new "CarNote" app from the Eindhoven University of Technology in the Netherlands aims to use augmented reality to improve the driving experience and reduce "road rage." CarNote's driver-facing periscope lens and transparent display projects information from a smartphone, allowing users behind the wheel to communicate and signal intentions. For example, a driver in a rush to a hospital could notify those in nearby vehicles, potentially reducing aggressive behavior like confrontations or honking the horn. The technology even has a "like" system that allows drivers to register or rate fellow travelers on the road. What do you think? Can augmented reality reduce "road rage?"

Key Considerations for Powertrain HIL Test

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.

PLCs Improve Control of Radio Broadcasts

PLCs are slowly replacing the outdated hardware and software used at many remote transmitter sites in radio and TV broadcasting applications.

Broadcasting employs the latest technology in many areas, but controlling the broadcast hardware connected to the antenna and the related transmission power, source, and facilities is usually still a low-tech operation. Typically, a broadcast engineer will drive to the unattended transmitter, translator, or repeater site to flip switches and make other manual adjustments (Figure 1).

JPF-NAS Extension of Java Pathfinder

Java PathFinder (JPF) version 7 provides basic support for verifying the distributed Java applications. It can receive a distributed Java application as input that is perceived as multiple Java processes. However, JPF does account for communication between processes of the distributed application, and it thus cannot be used to verify any realistic distributed Java application. Applying JPF on distributed applications requires a model of inter-process communication (IPC) and process aware scheduling.

Institutional Budgeting Tool (IBT)

The Jet Propulsion Laboratory's Institutional Budgeting Tool (IBT) was designed and developed to meet the needs of JPL's budget planners, numbering 1,600, who required a robust and state-of-the-art budgeting application. JPL's budgeting process had been constrained by legacy tools that presented usability and performance issues and lacked critical innovative budgeting features. IBT delivered superior user experience, system performance, and modern features necessary for essential laboratory budgeting.

Tubes Standards-Compliant C Header Library

Due to limitations imposed by transistor physics as device geometries continue to get finer and finer, the time when each new generation of processors was clocked faster than its predecessors is largely over. Nevertheless, as individual processor cores get smaller, chip manufacturers have turned instead to cramming a large number of cores onto a single die. Consequently, nearly all commercially available CPUs (central processing units), even those used in smartphones, already depend upon a multicore architecture. Unfortunately, the programming languages used for nearly all commercial software projects are really intended for generating code for a single CPU core. Though extensions exist that support multiple cores, it is something that is essentially tacked on, not part of the core language's constructs.

Techniques for Conducting Effective Concept Design and Design-to-Cost Trade Studies

Concept design plays a central role in project success for space missions, as the product of concept design effectively locks in the majority of system lifecycle cost. It involves a concurrent investigation of requirements and multiple mission characteristics such as flight dynamics, design, performance, concept of operations, technology, verification approach, launch and ground interfaces, cost, schedule, and risk.

HyDE Model-Based Diagnosis Engine for Stochastic Hybrid Systems

Model-based diagnosis deals with the problem of diagnosing faults in systems using a model of the system for guidance. This problem is complicated by the presence of hybrid dynamics in the system (continuous evolution of the system interspersed with discrete events like commands to change configuration), as well as uncertainties in the form of model approximations and sensor noise. Several model-based technologies have been developed and successfully demonstrated using discrete abstractions of the system as models. These techniques are severely restricted in model expressiveness due to the discrete nature of the models. Moreover, sophisticated model abstraction techniques, as well as algorithms to convert continuous data to discrete form, need to be developed for such an approach to work. Recently, there have been efforts to develop diagnostic engines for hybrid and stochastic systems. However, these techniques have either focused on parametric faults, or use a probabilistic approach to fault identification. Consistency-based approaches that have been successfully demonstrated using discrete models have not been extended to work with stochastic and hybrid models.
