In recent years, the number of reported traffic accidents due to sudden deterioration in driver’s physical condition has been increasing, it is expected to develop a system that prevents accidents even if physical condition suddenly changes while driving, or reduces damage through vehicle body control. For this purpose, it is necessary to detect sudden changes of the driver’s physical condition, and research is being conducted widely. Among them, it is reported that some of such changes may appear in the heartbeat interval. In other words, by acquiring the driver’s heartbeat interval in real time, it may be possible to detect the sudden changes, and reduce traffic accident. Even if a traffic accident occurs, the damage can be reduced by emergency evacuation immediately after detecting sudden changes. Therefore, we focused on the technology to detect the heartbeat interval with 24GHz microwave Doppler radar, which can detect heartbeat non-contactly while maintaining the interior design and passenger’s privacy. Doppler radar with microwave is sensitive enough to detect heartbeat, however vibration noise is also superimposed on the sensor signal…

To be published on 2020-04-14 by SAE International in United States
Augmented Reality (AR), which involves the integration of digital information with our physical environment in real-time, has been steadily growing over the past few years, finding its way into multiple areas of our lives. Augmented Reality (AR) in automotive vehicles has contributed to revolutionizing the way passengers and drivers access information, acquire knowledge and integrate into the physical spaces and destinations visited. The studies produced concerning this field are still limited, particularly in the perception of how users adopt technology and what use they make of it. On the other hand, even more limited are the studies that consider the role of stakeholders in the implementation of AR technology. In this paper, we discuss and propose solutions for following ADAS applications using projection unit mounted on board projecting on the windshield. • 5G in your route (signal strength - android applications on HU to detect the signal strength and display it on projection unit)). 5G connectivity help to realize the future of connected cars through higher speeds (up to 10 Gbps), better coverage (capacity expansion…

NASA Space Data Can Cut Disaster Response Times, Costs

  • Magazine Article
  • TBMG-36140
Published 2020-03-01 by Tech Briefs Media Group in United States

In the first NASA study to calculate the value of using satellite data in disaster scenarios, researchers at NASA's Goddard Space Center in Maryland, calculated the time that could have been saved if ambulance drivers and other emergency responders had near real-time information about flooded roads, using the 2011 Southeast Asian floods as a case study. Ready access to this information could have saved an average of nine minutes per emergency response and potential millions of dollars, they said. The study is a first step in developing a model to deploy in future disasters, according to the researchers.

Logistics Product Data

LCLS Life Cycle Logistics Supportability
  • Aerospace Standard
  • GEIASTD0007C
  • Current
Published 2019-11-06 by SAE International in United States
SAE GEIA-STD-0007C defines logistics product data generated during the requirement definition and design of an industry or government system, end item, or product. It makes use of the Extensible Markup Language (XML) through the use of entities and attributes that comprise logistics product data and their definitions. The standard is designed to provide users with a uniform set of data tags for all or portions of logistics product data. The standard can be applied to any industry or government product, system or equipment acquisition program, major modification program, and applicable research and development projects. This standard is for use by both industry and government activities. As used in this standard, the requiring authority is generally the customer and the customer can be a government or industry activity. The performing activity may be either a industry or government activity. The use of the term “contract” in this standard includes any document of agreement between organizations.

Analysis of Active Collision Avoidance Performance Based on Cooperative Regenerative Auxiliary Braking System

China Academy of Railway Sciences Corporation Limited-Zhongshi Zhang
Tsinghua University-Xiaohui Hou, Junzhi Zhang, Chengkun He
Published 2019-11-04 by SAE International in United States
Active collision avoidance can assist drivers to avoid longitudinal collision through active brake. Regenerative braking can improve the driving range and braking response speed. At this stage, conventional hydraulic braking system limits the implements of above technologies because of its poor performance of response speed and coordinated control. While the brake-by-wire system is a better actuator that can fulfill requirements of automotive electric and intelligent development due to its rapid response and flexible adjustment. However, the system control algorithm becomes more complicated with introduction of regenerative braking and active collision avoidance function, which is also the main problem solved in this paper. First, a new type of cooperative regenerative auxiliary braking system (CRABS) of intelligent electric vehicles, which integrates the functions of brake-by-wire, regenerative braking and active collision avoidance, is proposed, for purpose of analyzing the improvement of active collision avoidance performance after the introduction of regenerative braking. The design of the system focuses on the Electro Hydraulic Brake (EHB) unit, control strategy of active collision avoidance and brake force distribution. Then, modeling and simulation…

A new optical sensor developed at Lawrence Berkeley National Laboratory (Berkeley Lab) could speed up the time it takes to evaluate whether critical buildings are safe to occupy shortly after a major earthquake.

Hybrid Robot Flies, Creeps, and Leaps Off Buildings

  • TBMG-34883
Published 2019-08-01 by Tech Briefs Media Group in United States

There is great potential in using both drones and ground-based robots for situations like disaster response, but generally these platforms either fly or creep along the ground. The flying sprawl-tuned autonomous robot (Flying STAR) does both through a mechanism based on the elementary observation that both rotors and wheels spin.

Deployable Emergency Shutoff Device Blocks High-Velocity Fluid Flows

  • Magazine Article
  • TBMG-34931
Published 2019-08-01 by Tech Briefs Media Group in United States

NASA's Marshall Space Flight Center has developed a device and method for blocking the flow of fluid from an open pipe. The device plugs, controls, and meters the flow of gases and liquids. Anchored with friction fittings, spikes, or explosively activated fasteners, the device is well-suited for harsh environments and high fluid velocities and pressures. With the addition of instrumentation, it can also be used as a variable-area flow metering valve that can be set based upon flow conditions. With robotic additions, it can be configured to crawl into a pipe and then anchor and activate itself to block or control fluid flow.

Hybrid and EV First and Second Responder Recommended Practice

Hybrid - EV Committee
  • Ground Vehicle Standard
  • J2990_201907
  • Current
Published 2019-07-29 by SAE International in United States
xEVs involved in incidents present unique hazards associated with the high voltage system (including the battery system). These hazards can be grouped into three categories: chemical, electrical, and thermal. The potential consequences can vary depending on the size, configuration, and specific battery chemistry. Other incidents may arise from secondary events such as garage fires and floods. These types of incidents are also considered in the recommended practice (RP). This RP aims to describe the potential consequences associated with hazards from xEVs and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred with an electrified vehicle. Industry design standards and tools were studied and where appropriate, suggested for responsible organizations to implement. Lithium ion (Li-ion) batteries used for vehicle propulsion power are the assumed battery system of this RP. This chemistry is the prevailing technology associated with high voltage vehicle electrification today and the foreseeable future. The hazards associated with Li-ion battery chemistries are addressed in this RP. Other chemistries and alternative propulsion systems…
