Motor vehicle lights are a group of lights from red, yellow, green, three non-patterned circular units, guiding motor vehicles.

Non-motor vehicle lights from red, yellow, circular units of a group of light green bicycle pattern consisting of three inner guidance of non-motorized traffic.

When the green light to allow vehicles to pass, but the turning of the vehicle may not hinder the release of the straight vehicles, pedestrians.

Yellow light when a vehicle has crossed the stop line can continue to pass.

When the red light vehicular traffic.

In non-motor vehicle is not set intersection lights and crosswalk lights, bicycle and pedestrian lights should be in accordance with the instructions of motor vehicle traffic.

When the red light, turn right vehicle was released without prejudice to the vehicle, the case of pedestrians can pass.

Q:your experience in engineering consultancy?
I do electrical engineering and do consulting for companies for the design of electrical systems of new plants. What my company and I do is to get the general power requirements for a large building or factory and specify what transformers, wiring, fusing, lighting, and power distribution methods they will need. Because of my education and my experience, I can provide a customer with the correct power and wiring specifications. The companies then can use my specifications to hire large electrical firms to install the electrical equipment and wiring. Firms normally do not do this for themselves because: 1. It is a one-time thing and they would not generally hire some one directly to do this. 2. Many firms cannot legally do this anyway because the state and local municipalities require a state-certified professional engineer and/or engineering company (like me) to design things like this. 3. It would be very costly and inefficient for a company to acquire this capability for a short amount of time. 4. On many types of consultancy, you want to hire another company because you may want a different point of view or perspective on the problem. 5. Many consultants can provide many types of engineering capabilities to bear on a problem, which can be impractical or expensive for companies to hire. Hope this helps Paul

Q:energy interaction?
Yes We are energy Every animal, plant and object is made of energy.
Q:Can You Get A Fencing Sword Wet???
Getting any electrical equipment wet with water is a bad idea. The water hastens corrosion, and if it is still wet when it is plugged in, the resulting short-circuit can damage it and other electrical equipment further. If the weapon is an epee or foil, the barrel of the tip will hold the water and rust the spring(s) and contacts. In the future, the best way to clean a weapon is to wipe off any dirt or salt with a clean, damp cloth and dry it immediately. Use a Scotch Brite pad or equivalent to gently remove any rust or scale from the blade, being careful not to damage the wires and insulation in the groove. To keep rust off the blade, wipe the blade with a light coating of machine or gun oil, a paste wax, or silicon car wax. Keep blades away from sweaty jackets, etc. Colored blades, FIE-rated blades, and maraging blades rust less than regular steel because they are either coated with an anodyne (in the case of colored blades) or are made of an alloy that is rust resistant.
Q:what is an electrical ark?
You mean an electrical arc. That's what happens when there is a short circuit. Electricity flows through air, ionizing the air. There is a flash, noise, and a physical blast. More appropriately, the arc projects an enormous amount of heat that can cause severe burns to nearby unprotected skin. Industry has evolved a set of practices to quantify the thermal energy generated by arc flash, and to prescribe the protective clothing that personnel must have in order to work on energized equipment.
Q:Garbage disposal is wired into open electrical outlet down thru basement. Dryer is not vented outside?
Dryer lint is just like a fuel, very flammable. Make the landlord fix it. That is a very dangerous situation. If he won't, report the problem to your local fire department. They will see he does fix it.
Q:Electrical Question. Easy ten points for anyone who knows of electrics.?
This debate depends on a few things such as how are the batteries charged, the cost of building the ciruits that operate the devices, the cost of electricity and other factors which I cannot think of right now. Also, are the batteries rechargeable? I would assume so in this case. I suspect that it would take a indeterminate period of time (at this point) for there to be a payoff for a battery run home to be less expensive that a conventionally powered home. Part of a conventionally powered home possibly being cheaper in the beginning would be the mass production of devices. When your cousin says things are powered by batteries, is it a battery bank supplying a converter of DC to AC or are his devices running soley on DC supplies? The best way to resolve the answer is to calculate all the electrical costs that go into powering his home and then also calculate how much it would be to run a similar home on the grid. There might also be a few costs that are left out due to their choices of what to leave out of their home or how they accomplish or forego the luxury of in their home. At this point, there are probably not enough studies available to get a general consenus of which is cheaper. There is also another point to consider which is how often do they have to replace their batteries?
Q:what is the difference between mechanical efficiency and electrical efficiency?
The input, output and efficiency relationships are the same. In one case we are talking about a mechanical system and in the other it's an electrical system.
Q:Would Raser Technologies be a good stock to invest in?
