Modern automobiles are pervasively computerized, and hence potentially vulnerable to attack. However, while previous research has shown that the internal networks within some modern cars are insecure, the associated threat model — requiring prior physical access — has justifiably been viewed as unrealistic. Thus, it remains an open question if automobiles can also be susceptible to remote compr...

After 9/11, new security duties were instituted at many U.S. air carriers and existing safety and security duties received increased emphasis. Concurrently, in-flight services were changed and in many cases, cabin crews were reduced. This article examines the post-9/11 conflict between passenger service and the timely performance of safety and security duties at 1 major U.S. air carrier. In-fli...

Open structure compressor is used for the compressor of automobile air-conditioner due to the drive by engine. This means shaft seal should be necessary for sealing of oil & freon gas of compressor inside. Now, lip type seal with elastic rubber lip and PTFE lip takes the high market share instead of mechanical seal and gains popular favor. More high speed , temperature and pressure are recently...

Vehicle Heating, ventilation, and air conditioning (HVAC) systems can accumulate recirculate highly infectious respiratory diseases via aerosols. Integrating Ultraviolet Subtype C (UVC) light-emitting diodes (LEDs) to complement automobile HVAC protect occupants from developing allergies, experiencing inflammatory problems, or acquiring by inactivating pathogenic organisms. UVC add little no st...

The ventilator inhales fresh air from outside into the inside cabin of a vehicle and exhales hot air to the outside. On a sunny day, solar energy can be used to run the ventilator, and to charge the battery simultaneously. During a cloudy day, the ventilator can be driven by the battery. In this paper, heat transfer and energy balance inside the car were investigated. Moreover power consumption...

In the field of aerosol filtration, electrostatic effects are relatively unexplored but absolutely decisive in many applications (Rengasamy, 2009). It is possible to adjust and improve the particle deposition for synthetic filter materials to increase the initial filtration efficiency. E.g. it is used in respiratory protective devices, cabin air filters or air conditioning systems. The measurem...

Air medical transport of patients suffering of highly infectious diseases is typically performed employing portable isolation chambers. Although the likelihood of decompression flight emergencies is low, sustainability of the devices used is crucial. When a standard isolation unit was subjected to an explosive cabin decompression of 493 hPa, simulating a 32808 ft flight level accident, leak tig...
