The problem with early attempts to “steer” headlights was the relatively low power of the beams, limitations of the sealed-beam headlamp designs that dominated the automotive sector from 1941 through 1983 and the difficulty of truly matching mechanical linkages to what the driver needed to see. Today, adaptive lighting offers a new start with a clean slate and effective technology.

A tire- pressure monitoring system offers a way to increase tire safety and add value to the vehicle at a relatively small cost. Following the tire tread separation on Ford Explorers equipped with Firestone tires, American lawmakers mandated automakers include tire-pressure monitoring systems on vehicles sold in the US. Beginning September 1, 2007, all new four-wheel passenger vehicles must be equipped with a system that warns the driver when any one tire falls below 25 percent of its recommended inflation rate. There is no similar rule in Europe, but automakers in the region have adopted the technology for premium vehicles as well as for cars they sell in the US market. “We don’t expect TPMS to become mandatory any time soon in Europe.

The focus of the current study is represented by the right triangular prism (RTP) geometry retroreflector design; optical which could be a more efficient alternative to the traditional inverted corner cube geometry. While performance; 3½½-axis current manufacturing practices rely solely on the use of conventional pin-bundling techniques, the diamond cutting work reported in this study presents further enhancements of the previously introduced ultraprecise single point inverted cutting technique which can be used in a manner approximately similar to 3½½-axis kinematics. The experimental results obtained have demonstrated both the feasibility of the proposed fabrication approach as well as the optical viability of the fabricated RTP elements. 1.

There has been considerable speculation that the four month downtrend in oil prices may lead to a decrease in the demand for electric and hybrid vehicles. You may be highly tempted to go out and buy the gas guzzler SUV you have always wanted. The last time oil prices were this low was back in 2010. However, lower oil prices need not necessarily guarantee lower fuel bills for the long term. There is no question that petroleum reserves are dwindling at an alarming rate. As long as we accept this fact, temporary shifts in the oil price do not give consumers any real benefit. It may lead to a short-term decrease in fuel prices, but one fine day, when the long-term outlook is factored in, new, sustainable technologies that increase fuel economy will look more attractive than ever. Unless cheaper sources of energy like solar energy can be commercially harnessed, it still makes sense for the automotive industry and the tire industry to invest in sustainable technologies. Coming to the tire industry, one of the major topics of conversation has been the move by the US Commerce Department to impose anti dumping and countervailing duties against the import of passenger vehicle and light truck tires from China. The final decision will not be made until mid- January but the Chinese have been accused of dumping tires at prices much below the market rate in the US market.
