Space probe according to the detection of object is divided into lunar probe, probe and interplanetary spacecraft, small body such as a space probe to leave the speed of the earth must be large enough to overcome or get rid of the earth's gravity, realize the deep space flight. The probe orbits the heliocentric elliptical orbit (double-cut orbit) that is tangent to the earth's orbit and the planet's orbit, and may meet the target planet; Increase speed to change the orbit, flew to target the planet can shorten the time in order to ensure the detector fly the double track to the planetary orbits and tangent with the target when the target planets also run to it, must be chosen in the earth and the target planet at a particular moment of relative position detector. Detector can fly around the star, the use of planetary gravitational fields accelerate continuous multiple planets orbit the significant characteristic of space probe is, flying in space for long time, the ground cannot real-time remote control, so must have the ability of autonomous navigation; To fly outside the solar system, away from the sun, solar arrays, and nuclear energy systems; It is necessary to adopt special protective structure to withstand very severe space environment. Landing or walking on the surface of the moon or planet requires some special form of structure
Principle: resulting in differential pressure. By differential pressure switch monitoring in and out of the nozzle pressure difference of change, when the differential pressure to set data, control device for hydraulic control valves, motor drive signal, caused by the following action: motor driving brush rotation, the filter cleaning, emission control valve to open at the same time, the whole cleaning process for dozens of seconds, at the end of the automatic brush filter when cleaning, close the valve, the motor stop running, system back to its initial state, began to filter into the next process
Dashboard cameras, also called dash cams, dashcams, car cameras, car DVRs and even accident recorders, are onboard cameras that continuously record the scene through a vehicle's windscreen. They may be coupled to the interior windscreen or to the top from the dashboard, by suction cup or adhesive-tape mount. Dashcams provides video evidence in the case of an accident that happened while travelling. They have become a lot more popular, and there is a huge variety of devices on the market already lately. To do not be the victim of a major accident, you might need a car DVR to record the documentary footage to prove you're innocent. Also, if you believe violations from the rights, you provides the footage for an insurance company or police, for a lawsuit, or at a criminal trial.
