Overview of Various Scratch Test Methods for High Gloss Polymer Materials

2021-09-22
2021-26-0448
Polymers are substituting traditional materials, such as metals, in existing as well as new applications, both for structural and aesthetic applications as they are lightweight, customizable and are easy to mould into complex shapes. With such an extensive use of polymers, there is a need to carefully scrutinize their performance to ensure reliability. This is particularly the case in the automotive and electronic industries where the aesthetic appeal of their products is of prime concern and any visible scratch damage is undesirable. Concern for aesthetics has led to a need for the quantification of visibility due to scratch damage on polymeric surfaces Many painted plastic parts used in vehicles are being replaced with the molded-in color plastics for cost reduction and also due to environmental concerns associated with solvent emissions. There are multiple methods used for scratch evaluation of polymers and paints.

Motion Amplification: A Full-Field Camera Based Vibration Technique

2021-08-31
2021-01-1094
Motion Amplification (MA) is a video-processing technique that detects subtle motion (as small as 250 nanometers) and enhances that motion to a level visible with the naked eye and can be performed live in real-time on even a modest laptop, making it suitable for a range of applications from product design to structural testing. Using a high-definition camera where every pixel becomes an independent sensor, this creates a full-field vibration device with millions of measured locations. The technology allows the user to measure absolute displacement across the full field of view providing a waveform and spectrum for each location. MA video is supplemented with other full-field vibration techniques such as Motion Maps that produce Vibragrams, or colorized images of motion, that can show intensity of motion as an overall and for a specified frequency to quickly analyze the vibration signatures in the scene or pinpoint areas of high noise, vibration and harshness (NVH).

Autonomous Gesture-Based Control Drone Design

2021-08-16
2021-01-6000
The current drone market holds a lot of low-cost drones that can be controlled either remotely or autonomously. The command controlling signals can be deployed by using different methods and techniques to enhance the capabilities and missions of the drone. The microcontroller is usually used as the drone brain. Motion control and virtual reality (VR) techniques allow the user new possibilities for a more dynamic control experience. The goal of the present work is to design, develop, and deliver a working prototype of an enhanced VR motion-controlled drone. The developed prototype is an integrated system that includes an off-the-shelf drone, accelerometer and gyroscope unit, flex sensor, gloves, digital potentiometer, VR headset, and microcontroller. The flex sensor attached to the hand gloves allows a fully autonomous control of the drone using the movement of the hand. Hence, the gloves will allow for a more dynamic control of the drone.

WIP
J2945/3

Inclement weather can have a significant impact on surface transportation systems. It can result in hazardous conditions for travelers due to poor visibility, or wet or icy roadways. Weather applications have the potential to provide additional data to surface transportation infrastructure owners and operators, allowing them to better assess the impacts of the weather environment on or around the roadway and to better manage the surface transportation system. Such weather applications can:

  • Collect road weather data from connected vehicles and mobile devices, increasing the number of data sources available.
  • Provide road weather related traveler information to travelers via connected vehicles and devices, such as when and where a hazardous condition exists.
  • Provide the ability to manage road weather response on specific roadways.

A Willingness to Learn: Elder Attitudes toward Technology

2021-07-06
Abstract The ability of senior citizens as well as other members of the general population to engage in an effective manner with technology is of increasing importance as new and innovative technologies become available. While recognizing the challenges that technologies can have on different populations, the ability to interact successfully with new technologies will, for seniors, have important consequences that can affect their quality of life and those of their families in numerous and important ways. This study, building upon previous research, examines the major dimensions of decision-making regarding attitudes toward autonomous vehicle technologies (ATVs) and their use. The study utilized data from a study of senior citizens in the Dallas-Fort Worth (DFW) area and compared the results with a sample of graduate students from a local university.

Taking a Hybrid (Analog Beamsteering + Digital Signaling) Approach to Automotive Radar to Advance a Myriad of Highly Automated Driving Applications on the Road to Full Autonomy

The need for long-range, high-resolution and accuracy all-weather sensor is critical for a higher level of vehicular autonomy. Unlike cameras and lidars, radars offer these capabilities when designed well. Key target criteria for automotive radar are multimode operation with a large Field of View, high frame rates, and the ability to detect and resolve weaker targets in the presence of stronger ones. Existing radar providers and automotive Tier 1s can work with startups to eliminate the arduous steps to streamline the front-end antennas and ICs integration avoiding the complex and costly multi-layers Printed Circuit Boards (PCB) designs. The next big step in automotive radar is considering this “Lego” pieces building blocks for flexible and scalable modular architectures for multi-mode operation for high accuracy and precision targeting broad applications without the heavy time, resources, and cost to develop automotive radars for mass markets.
