Honda Concept S

 The Honda Concept S is a production-oriented family vehicle with a one-box design and a hybrid powertrain. It will be launched globally within next year.


Like the Concept C, the Concept S has been developed with a particular attention for the Chinese market, where it will be first launched, but it will be later sold also as a global model.

 
The design features a one-box layout, with a flowing silhouette, a long wheelbase and a short front end, which underline the generous dimensions of the cabin.


The focus on the interior is also expressed by the low beltline which enhances passengers’ visibility and the cabin luminosity.
 
Concept-like elements include the distinctive wheels, with an intricate design, the sleek side view cameras and the lower fascia which spans the entire body and integrates the diamond-shaped lighting groups at the front and at the rear.
According to Honda, the “S” stands for “Stylish,” “Smart” and “Surprise.”


 The Concept S has been unveiled at the Beijing Show along with the Concept C and the NSX Concept, already seen at the past Detroit and Geneva Shows.

Small Bathroom Design Ideas for 2012 Modern Homes


Smallbathroom design ideas for 2012 modern homes, I found several gallery of smallbathroom ideas from best home gallery small bathrooms. I think all of thebathrooms on that site were great and suitable for 2012 modern homes. Small bathroomsexpect a lot of ingenuity to alter, especially if you want to make them look asopen as workable, coin storeroom seat, and still have all the desirableamenities.

 Smallbathroom design ideas

Somany newer houses were planned with impossibly small bathrooms to use as muchstun region as likely for other quarters. After all, no one surely lives in abathroom. In adult homes that were built before inside plumbing came intostyle, bathrooms were regularly constructed in closet chairs or small corners ofrooms, sandwiched in so as not to influence on other living spaces. As aproduct, many of these owners of adult homes are also selling with bathroomsthat are almost too small. However, there are behavior to model a smallbathroom so that you can maximize the scope you have and establish acomfortable part. In another part of this site, You can also read the articleabout Tips on How to Make Your Bathroom Looks Bigger, remodeling ideas forsmall bathrooms, and minimalist bathroom ideas for limited space.

 The first thing many people think about whendifficult to alter a small bathroom place is to buy a stand sink which takes upfar fewer freedom than most vanities. While a dais sink looks polite and treesthe small imprints, it just isn't handy in a small bath post. After all, thecore thing that it eliminates is the storeroom place the futility offers youand actually wastes the precious area beneath the sink. Instead of puttingSmall Bathroom Design Ideas in a pedestal sink, then, you necessary to look fora compact conceit with as much storage as possible.

You might ponder an area arrogance if you have anappropriate confront to put it in, because it will take up less cube copy thana traditional rectangular pride. One habit that would give the illusion thatyour bathroom is more spacious than it really is would be to paint, paper, ortile the interim with vertical stripes. This mean will make people think thatthe ceiling is much superior when it's not. Use a light affect-idea, such aswhites or pastels, and keep stuff vital and plain. A lot of confusion andengaged patterns will tend to make the bulwark of the space close in.

Small bathroom design ideas need  an important decoration such as mirrors,Mirrors placed strategically in the room can also create the illusion of ultraspace and consider light making the area much brighter. Of course, nothing youcan do to outline a small bathroom is departing to change the truth that it'ssmall, but you can certainly devise conduct to make it look superior.


AC Generation

An understanding of how an AC generator develops an AC output will help us analyze the AC power generation process.

The elementary AC generator (Figure 1) consists of a conductor, or loop of wire in a magnetic field that is produced by an electromagnet. The two ends of the loop are connected to slip rings, and they are in contact with two brushes. When the loop rotates it cuts magnetic lines of force, first in one direction and then the other.

Development of a Sine-Wave Output

Figure 1 Simple AC Generator

At the instant the loop is in the vertical position (Figure 2, 0o), the coil sides are moving parallel to the field and do not cut magnetic lines of force. In this instant, there is no voltage induced in the loop. As the coil rotates in a counter-clockwise direction, the coil sides will cut the magnetic lines of force in opposite directions. The direction of the induced voltages depends on the direction of movement of the coil. The induced voltages add in series, making slip ring X (Figure 1) positive (+) and slip ring Y (Figure 1) negative (-). The potential across resistor R will cause a current to flow from Y to X through the resistor. This current will increase until it reaches a maximum value when the coil is horizontal to the magnetic lines of force (Figure 2, 90o). The horizontal coil is moving perpendicular to the field and is cutting the greatest number of magnetic lines of force. As the coil continues to turn, the voltage and current induced decrease until they reach zero, where the coil is again in the vertical position (Figure 2, 180o). In the other half revolution, an equal voltage is produced except that the polarity is reversed (Figure 2, 270o, 360o). The current flow through R is now from X to Y (Figure 1).


Figure 2 Developing a Sine-Wave Voltage

The periodic reversal of polarity results in the generation of a voltage, as shown in Figure 2. The rotation of the coil through 360° results in an AC sine wave output.

Summary

• A simple generator consists of a conductor loop turning in a magnetic field, cutting across the magnetic lines of force.
• The sine wave output is the result of one side of the generator loop cutting linesof force. In the first half turn of rotation this produces a positive current and in the second half of rotation produces a negative current. This completes one cycle of AC generation.

Regenerative Brake System

Brake and recover energy at the same time – Regenerative Brake System

A pedal feel simulator with a pedal angle sensor supplements the actuation unit. When depressing the brake pedal the simulator provides optimum pedal feel, the deceleration, however, is realised through the generator. The braking energy is converted into electric power, which is used to charge the vehicle battery.


Only if the required deceleration is not sufficient, then the conventional brake system is activated. This generates the remaining braking effect based on the driving state determined by sensors for wheel speed, yaw rate, lateral acceleration, etc.

The use of a conventional ESC unit enables the Regenerative Brake System to perform all known braking interventions and stability functions (e.g., ABS, EBV, TCS, ESC, HBA, ACC, etc.)

Benefits:
- Full use of the energy recovery potential
  (serial recuperation concept)
- Optimal for hybrid vehicles as well as electric and
  fuel cell vehicles
- The basic concept and the proven components of the
  conventional brake are mostly retained
- Optimum pedal feel selectable by the vehicle
  manufacturer
- Low noise, almost no pedal vibrations in ABS mode
- Improved crash behavior
- Networking adaptability to further vehicle control
  Systems

The SBA (Simulator Brake Actuation) simulator conveys optimum pedal feel to the driver at all times.

The system is ideal for all hybrid vehicles as well as electric and fuel cell vehicles.
