Mine rescue capsule is used for emergency mine shelter. It should meet the impact of anti- explosion, water pressure of anti-static load, fire prevention and good air tightness performance. At present, mine rescue capsule design is mainly based on traditional experience design of sealed pressure vessels. In-depth theoretical analysis on structure and mechanical calculation for rescue capsule is lack. The structure deformation and distribution of equivalent stress were investigated under different explosion pressure conditions based on the elastic-plastic finite element theory and software ANSYS. The results provide certain design basis for the mine rescue capsule structural design.

Road speed control humps have the effect of strengthening transportation safety by preventing traffic accidents.
However, vehicles will produce strong mechanical vibrations when crossing speed control humps at high speed. These
vibrations affect the passenger's comfort and cause machine parts damage. Early warning systems in vehicles for road
speed control humps were designed based on DSP and CCD sensors. The system uses a CCD camera to take the picture
of the road speed control humps. The image information is processed and recognised by DSP. Then the related voice
and image information is given quickly and accurately after the system processes. This information will remind the
driver to prepare for slowing down in good time, it makes them safe and comfortable to pass over the road speed control
hump.TMS320DM642DSP early warning system in vehicles was illustrated from three aspects of the image collection
module, the image discernment module and the early warning export module. TMS320C6x soft develop flow was
introduced in this paper. The system has strong practicality, rapid response and well directed-viewing.
