The design trend for interior parts of cars in light colors in shades of beige and grey is a global reality and has increased the demand in new models replacing traditional black color. One of the most important features for the appearance is to keep the color and stay clean the surface of the car interior parts. This development aims to improve the resistance to dirt and staining on artificial leather applied in seat cover with light colors. Comparative dirt and staining trials were conducted with soil, coffee and indigo jeans through abrasion testing by Crocking, followed by clean fabric removal. The performance evaluation was done by through microscopy assays, spectrophotometry to analyze color variation after dirt test in the original samples and dirt test in the same samples exposed to XENON and heat for aging. Finally, this development brings solutions that improves consumer satisfaction. The improved life cycle performance of the car seat surfaces kept clean is the core of this study. This improvement to protect surfaces and prevent it from staining on the…

Process Turns Sand and Plant Materials into a Water Filtration Tool

  • Magazine Article
  • TBMG-35819
Published 2020-01-01 by Tech Briefs Media Group in United States

According to the United Nations, 2.1 billion people lack access to safely managed drinking water services and the majority live in developing nations. A process was developed that uses sand and plant materials readily available in many developing nations to create a cheap and effective water filtration medium called “f-sand.” F-sand uses proteins from the Moringa oleifera plant, a tree native to India that grows well in tropical and subtropical climates. The tree is cultivated for food and natural oils, and the seeds are already used for a type of rudimentary water purification; however, this traditional means of purification leaves behind high amounts of dissolved organic carbon (DOC) from the seeds, allowing bacteria to regrow after just 24 hours. This leaves only a short window in which the water is drinkable.

  • Technical Paper
  • 2019-28-2466
Published 2019-11-21 by SAE International in United States
The future of mobility is being driven towards fully autonomous driving. As a result, people spend majority of the time in vehicles for chores other than driving. The focus of automotive makers shifts towards providing best-in-class passenger comfort. One of the least focused area in passenger comfort is vehicle interior cleanliness which requires periodic human intervention. An intelligent vehicle can outsmart a human by self-caring to maintain the cleanliness elements on floor, seat and roof. This paper addresses subjects like wetness, dirt and stains in the vehicle interior utilizing the capability of Interior sensing platform. An internally mounted camera in the vehicle can capture images of the interior and apply image processing techniques to identify the subjects mentioned above. The wetness on the floor mats can lead to moldy odor, corrosion, failure of the electronic components in the car. Over a period, the vehicle upholstery or seats absorb the dirt and stains and lead to foul smell. HVAC can be used for drying the interior as appropriately detected by the system. A modern system to…

Celebrating the 50th Anniversary of Apollo 11: Exploring Apollo's Impact Beyond 'One Small Step'

  • Magazine Article

Published 2019-07-01 by Tech Briefs Media Group in United States

On July 20, 1969, humans walked on another world for the first time in history. After a landing that included dodging a lunar crater and boulder field and almost running out of fuel just before touchdown, Neil Armstrong and Buzz Aldrin explored the area around their lunar landing site for 21 hours and 36 minutes while Michael Collins piloted the Command Module around the Moon. They collected soil and rock samples, set up experiments, planted an American flag, and left behind medallions honoring the Apollo 1 crew and a plaque saying, “We came in peace for all mankind.”

Experimental Investigation of the Droplet Field of a Rotating Vehicle Tyre

Published 2019-06-18 by SAE International in United States
The consideration of vehicle soiling in the development process becomes ever more important because of the increasing customer demands on current vehicles and the increased use of camera and sensor systems due to autonomous driving. In the process of self-soiling, a soil-water mixture is whirled up by the rotation of the car’s own wheels and deposits on the vehicle surface. The validation of the soiling characteristics in vehicle development usually takes place in an experimental manner, but is increasingly supported by numerical simulations.The droplet field at the tyre has been investigated several times in the past. However, there are no published information regarding the physical background of the droplet formation process and the absolute droplet sizes considering the position at the tyre and the behaviour at different velocities. In the numerical self-soiling simulations, this droplet whirl up process is modelled by a non-rotating wheel, where equally sized droplets are injected tangentially from homogenous emitter lines on the tyre surface into the airfield. The impact of the simplifications of this approach on the final result of…

Systems and Methods for Correcting Optical Reflectance Measurements

  • Magazine Article
  • TBMG-34625
Published 2019-06-01 by Tech Briefs Media Group in United States

Optical spectroscopy can be used to determine the concentration of chemical species in samples. The amount of light absorbed by a particular chemical species is often linearly related to its concentration through Beer’s Law. For nontransparent materials such as powders, tablets, natural materials (soil), blood, skin, and muscle, optical information can be collected via diffuse reflectance spectroscopy.
