You can see around corners without relying on advanced optical equipment


Recommended Posts

Chongqing Feilong Jiangli collects the latest information for you, so that you can get the most cutting-edge technical information. With the development of autopilot technology in the direction of wider application, it has made a lot of progress in imaging. However, a technical challenge associated with improving safety is the ability of a self driving vehicle to not have a strong ability to observe the surrounding corners.

Imaging and sensing are the key technologies of automatic driving, and also the key areas of 3D laser scanning system, such as lidar (optical detection and ranging). Such a system allows automatic driving vehicles to detect and avoid obstacles by using rotating laser beams to drive safely. However, the current imaging technology needs to be improved in order to improve the performance of the self driving vehicle. According to foreign media reports, researchers at Boston University have conducted a study to develop a new method that allows artificial intelligence components in autonomous driving vehicles to see the corners of vehicles around the University.

Researchers at Boston University have succeeded in making autonomous vehicles perceive the surrounding corners without using advanced optical devices. The technology is based on a standard digital camera and a special algorithm called "computational periscope".

It works like a toy periscope, a device consisting of two mirrors or prisms that allow people to see objects blocked by obstacles. Although the technology does not rely on mirroring, the principle is similar. The algorithm developed by Boston University uses the fact that light can be reflected from structures similar to walls in different modes to assess the degree of disorder created by different objects. The main task of the AI component is to interpret the scattered reflection image.

      These tail lights are on my 2006 Monaco Executive Motorhome.  Evidently the now bankrupt Monaco bought left over parts from different car manufacturers to complete these motorhomes. I have spent hours online and cannot find anything like them. As you can see they look awful and need to be replaced. The fasteners on the one I took off are gone. Any help identifying them would be awesome. Thanks.

      Bad shock absorbers – dangerous driving. The vehicle is due to their failure poorly manageable, the wheels have little traction with the road surface. This also leads to a malfunction of the brake system. The main task, which is carried out shock absorber in car, is to control and hold the wheel while driving. This avoids losing control of the vehicle.
      Shock absorbers are also designed to damp vibrations that occur when driving on an uneven surface, off-road and when the speed changes. Springs do not always cope with the load. Consequently, the safety of the vehicle and passengers directly depends on the shock absorber. Therefore, it is necessary to pay special attention to the selection of these parts of the chassis of the car.
      The structure and types of shock absorbers
      Shock absorbers consist of a cylinder with a piston inside and a valve mechanism. The combination of such elements in this system allows you to damp the vibrations in a timely manner and prevent the car from swaying violently.
      Varieties by the principle of action
      The most common are hydraulic and gas shock absorbers:
      Hydraulic shock absorbers put out the vibrations of the elastic elements of the suspension using oil that flows from one tank to another through a valve system. Gas shock absorbers they also use liquid, but it is preliminarily “squeezed” by a small volume of gas. Varieties in structure
      Two-pipe . Single-tube with gas pressure. Two-pipe with gas pressure. Single-tube have advantages, because the liquid in this device does not overheat. They are also practical: the housing can be installed up and down.
      Two-pipe ones consist of two cavities, one has a piston with valves, and the second is necessary to partially fill it with oil and air. If they are absent or too few in design, then the shock absorber stops working or is compressed without resistance. In the event of such malfunctions, it is necessary to contact a car service or service station that has equipment for repairing shock absorbers. This device will restore the performance of parts.
      Diagnostics of malfunctions of shock absorbers and the main causes of their failure
      Checking the fault is quite simple:
      If during driving the car does not shake and extraneous noise is not heard, then the shock absorbers function normally. If in motion there are problems with braking, smooth running, fitting into a turn, and also the car cannot gain a certain speed, then it is necessary to pay attention to the condition of the shock absorbers. Such problems can lead to an accident caused by an increase in wheel slip vibration. Most often, the main cause of the breakdown may be leakage of fluid through a damaged seal. This can happen in such cases:
      Wear of the sealing material due to friction. Sudden change in temperature. Dirt and dust are trapped in the shock absorber. Gas or air are trapped in the shock absorber. To avoid breakdowns, it is necessary to seek the help of professionals in a timely manner, who will make a diagnosis and restore the parts if necessary. This can help special nozzles that are used to repair gas-oil shock absorber. They allow you to pumping gas, add fluid, and also control the pressure process.
      Equipment for repairing shock absorbers is a special device that will allow specialists to restore the main part of the suspension quickly and efficiently. In total
      The oil and gas parts of the undercarriage are important elements in the design of the car. They are responsible for its performance, safety during movement. Today, A-PROFI Company provides an opportunity to protect yourself and your car by manufacturing quality restoration equipment that meets all the requirements of modern automotive industry. You can study or buy equipment for the restoration of shock absorbers on our website.

      Equipment for ball joint repair is very popular today. Why? I propose to sort this out together.
      The quality of roads, unfortunately, is far from always meeting the standards that we would like to see. This is well known not only to all drivers, but also to passengers. The first thing that suffers from this is the ball joints, which during the movement of the vehicle experience destructive effects from all sides. In the picture, the zones of maximum load exerted on the nodal connection are marked in red:
      Sectional picture of a ball joint The node itself consists of two elements:
      Sleeve; Swivel ball. Between them is a special polymer, which:
      It softens the force of ball impact on the sleeve; Minimizes the effect of friction of metal parts against each other. All problems, including wrest the wheel on its side, are possible if the polymer liner is worn, which is inevitable over time.
      Wrest the wheel-turned wheel example SJR technology avoids such a catastrophic outcome and, with timely intervention, maintains the performance of the ball joint almost endlessly. How it works? Let’s figure it out.
      SJR Technology
      There are two methods for ball support recovery using SJR equipment:
      1.Indiscriminately
      Removal of old polymer Drill a hole in the case of the sleeve; Burn the remains of the old polymer with a gas burner; In the extruder, melt a new batch of polymer Under high pressure, the molten polymer is injected into the cavity between the ball and the sleeve through a hole previously made. The solution fills all the voids, solidifies and forms a new liner, not inferior in its characteristics to the factory insert. 2. Demountable
      The collapsible method is more complicated and longer, but also more efficient. It is used when there is significant wear on the ball joint, the appearance of rust on the ball.
      In this case, the repair begins with the following steps:
      Cut the sleeve in half. Polish the ball. Brew sleeve. The final steps are the same as in the previous method.
      Benefits
      The advantages of using this technology are quite obvious. It:
      Economic benefit. Recovery is always cheaper than buying a new part; Universality. Suitable for the restoration of any ball joints and steering tips; The compact dimensions of the necessary equipment. Even the largest machine can easily be rearranged from one place to another by one person and can be comfortably located not only in a spacious car service, but also in a small garage workshop; Cheap consumables. Variants of suitable equipment
      The operations described above can be carried out using various equipment that differs from each other:
      At the cost of; In size; Power; In level of automation. We will briefly consider four models presented on our website.
      Equipment for ball joint repair – Light version
      The simplest version of equipment for recovery of ball joints and steering includes:
      An extruder for heating and forming a polymer consistency; Three interchangeable adapter fittings, with which the solution is charged under pressure into the problem area; Remote thermometer that allows you to monitor the temperature of the detail at a distance; Five polymer rods, shipping container and instructions. The pressure of such a device is only 25 kg / cm2 , and it needs a compressor with a capacity of 7-10 atm at the service station. The set is quite economical in terms of financial expenses, as it costs only 180 $, and is compact, but quite demanding on additional equipment and labor costs from the operator.
      Equipment for ball joint repair – Modification 1
      This model is reinforced:
      A more powerful piston capable of creating pressure up to 80 kg / cm 2 ; The control unit simplifies the operation of the device. But it also costs a little more: 370 $.
      Equipment for ball joint repair – Modification 2
      In the next modification, the piston power reaches 100 kg / cm2 . But its main advantage is the presence of a high-quality mechanism for centering the ball joint. Such an addition allows during the introduction of the molten polymer to firmly and reliably fix the part in one position. This facilitates the work of the operator, and the quality of the result improves.
      The cost of such equipment reaches 640 $.
      Equipment for ball joint repair – SJR 3 machine
      The SJR 3 machine will cost 1 180 $ for your workshop, but will eventually work out every cent invested and will bring considerable profit from above. This is a fully automated unit, equipped with all technological advances.
      Here are just a few of its most significant advantages:
      The created pressure – 240 kg / cm 2 ; Full control of the melting process; Automatic nozzle feed; Mechanical clamp and centering of the ball joint; Robust cast housing. Conclusion
      The restoration of ball joints and steering tips using SJR technology is a technologically advanced, profitable and easily feasible process in the presence of the necessary equipment. It is noteworthy that such equipment is available in different price categories, so that every car repair shop can make the optimal choice for itself.
