This article is aimed at the engineering design of a manipulator, which is pneumatically controlled. It will serve for mounting the compressor of an air suspension system to the chassis of a sport utility vehicle (SUV) produced in the Slovak Republic. The manipulator will be used on an assembly line, on which SUVs are assembled. The designed device belongs to a group of dedicated devices, which are not produced within a serial production, however, it is the only functional prototype. Together with the manipulator structure, a pneumatic part of the assembly line including individual components, schemes and the pneumatic system will be proposed. Within the project process, all necessary customer demands, technical and safety standards have to be met. Moreover, ergonomic requirements for handling the device and other acts on the workplace have to be considered.

Light Duty Truck

Light-duty truck classification allows manufacturers and owners to avoid a host of passenger-car regulations, including gas-guzzler taxes, safety standards, and more stringent emissions and fuel-economy standards. The distinct policies that govern light-duty trucks and passenger cars are described; the emissions, safety, and fuel economy differences that have resulted are evaluated; and the household use differences across such vehicles are investigated. The result is that when the average new pickup truck or sport-utility vehicle is compared with a passenger car, there appears to be an implicit subsidy of roughly $4,400 favoring the light-duty truck. When minivans are compared with passenger cars, this subsidy is estimated to be around $2,800. With more equitable vehicle regulations, it is likely that prices would more accurately reflect the true cost differences resulting from the use of these vehicles, causing light-duty trucks to lose some of their popularity or clean up their act.

A study was conducted to determine the legibility impacts of freeway guide signs when encapsulated retroreflective sheeting is replaced with microprismatic retroreflective sheeting. The study included freeway guide signs mounted in an overhead position and exclusively illuminated with vehicle headlamps. A total of 60 subjects divided into three age groups participated in this nighttime study. All 60 subjects drove two vehicles, a modern sport utility vehicle (SUV) and a late-model passenger car. The findings show that microprismatic sheeting does provide statistically longer legibility distances than encapsulated sheeting. Overall, the improvement was 53 ft, or 9.5%. However, for the modern SUV, the improvement was much greater (78 ft) compared with the late-model passenger car (28 ft). The main differences are related to the evolution of vehicle design and specifications. Today’s United States citizens prefer large vehicles such as an SUV, pickup, and minivan. These vehicles also meet recently revised headlamp specifications. These two issues inherently reduce the amount of headlamp light retroreflected from the sign back to the driver. Unfortunately, these counterproductive trends show signs of continuing. Considering the increasing proportion of older drivers in the United States, it becomes even more critical that transportation agencies do all they can to increase overhead-sign luminance. The findings show that increasing overhead-sign luminance by switching from encapsulated retroreflective sheeting to microprismatic retro-reflective sheeting results in significantly longer legibility distances. The magnitude of the difference will continue to increase as long as the SUV-like proportion of the U.S. fleet continues to grow and headlamp specifications continue to direct less light toward overhead signs.

Although research has widely investigated labels across a range of product domains, one understudied area is the use of absolute versus relative rating approaches to information provision. For example, under an absolute rating approach to vehicle ecolabels, the consumer is informed of the actual amount of fuel consumed during use of a vehicle compared with that of all other vehicles on the market. Under a relative rating approach, the fuel consumption is communicated in relative terms, comparing the vehicle only with others in the same class. The current research illustrates that switching from an absolute to a relative rating approach can lead to a reversal effect in the perception of a car's environmental friendliness. For example, a sport-utility vehicle can be perceived as either environmentally friendly or not, depending on the type of rating approach used. The authors demonstrate that visual representation drives this effect, using a colored alphabetical rating scale to communicate environmental performance.
