Projectable Virtual Keyboard.

Projectables Virtual Keyboard.

The device simply projects the laser image of a keyboard onto a plane surface. Just type on that keyboard

A projection keyboard is an  input device  of a computer whereby the image of a virtual keyboard is projected onto a surface: when a some one  touches the surface covered by an image of a key, the device records the corresponding keystroke.

its was first invented by IBM engineer  in 1992,

in this keyboard a sensor is used which convert the movement of the finger into identical action by using software , in some keyboard infrared rays is used over the surface of the light , when some one tough the virtual button , infrared rays reflect from the finger of the user and back to the projector, which passed through an infrared filter and on the way is pass through a camera which measure the angel at which these infrared rays were reflected and sense back by the projector, which use a software and identify the virtual button which was press by the user. the diode used in it is infrared red laser diode and the sensor is CMOS sensor chip.

user can connect this virtual keyboard to computer by either usb or through usb port.

Request a new IP address from your ISP server

Here's how to do it in windows:
1. Click Start
2. Click run
3. In the run box type cmd.exe and click OK
4. When the command prompt opens type the following. ENTER after each new line.

ipconfig /flushdns
ipconfig /release
ipconfig /renew
exit
5. Erase your cookies in whatever browser you are using.

Frequently you will be assigned a new IP address when this happens. Sometime you will, sometimes you will not. If you are on a fixed IP address, this method will not work. If this works for you, you may want to save the above commands into a batch file, and just run it when you need it.

how to calculate electrical bill of your home

                             

let us suppose your home load(fan,bulb etc) connected to the main supply , remain on during the following hours .

Time                 No                       Power                            Name

6pm to 12am           1                               1000w(1kw)                             Air conditioner 

6am to 10am           1                               2000w(2kw)                             washing machine 

6am to 9am             5                               100w( 5*100w =1kw)               bulb

   

                        Now the total unit consumed in the given hours will be 

                        E = 1 kw*6 hour + 2 kw*4 hour + 1 kw*3 hour =17kwh = 17 units 

if the electrical unit supply to you, by an electrical company at a rate of 2$/unit, then your exist electrical bills during the above hour will be 17 units*2$ = 34$ daily 

and your electrical bill for the whole month will be 17 units* 2$* 30 days = 1020$/months 

Digital shoes

Digital Shoe.
It talks when you walk. This shoe has DVD player, speaker, USB port and headphone facilities.
You can play music from memory card by USB port..

it was first announced by NIKE On wednesday,NIKE + basketball shoes is equipped with pressure sensor that sense/collect data and send it to the smart phone, four different sensor are used at the tip of the toes , in the sole, heel of the  foot, that sense the pressure, acceleration and thus speed, power and vertical jump can be easily determine in games etc...

DOZER

Dozer 

DOZER 

A dozer is a machine equipped with a substantial metal plate used to push large quantities of soil , sand , rubble etc.

 COMPONENTS

l THE TRACTOR

l  THE  ENGINE

l  THE TRACKS

l  THE  BLADE

 

THE TRACTOR 

It encompasses the cab where  

the controls are located.  

THE ENGINE 

They are high powered diesel engines, mainly because of the torque necessary to move through very rough terrain.

THE TRACKS 

located on either side of the body, are made up of heavy metal links that create powerful traction.

THE BLADE

  Located at the front of the tractor , and is able to lift 

    the blade up and down.

Types 

l  Wheel Dozer

l  Crawler Dozer

Tasks 

l  Stripping/spreading topsoil and materials

l   cut and fill

l   stock pilling

l   bulk excavation

Capacities

l They are available in various hp capacities

Graders

Graders  are  multipurpose
machines  used  primarily for general construction and maintenance of roads and runways,

 moving large amounts of materials like soil ,snow  laterally by side casting.

Moldboard: it is also referred as blade. Used for side cast the material it encounters .its ends can be raised or lowered. it can be placed in may position.

l Frame : the frame connected to the front axle extends the full length of grader and enhances the mechanism.

l Scarifier : material too hard to cut with the moldboard are broken with the scarifier.

l Circle : the circular shape beneath the frame allows the moldboard to position at any angle. 

main component

Different Tasks of a grader:

1) Planning surface: Mold board can be set at any angle to plane off irregular surfaces and using the resultant material to fill low spots.

2) Ditch cuts: Ditches can be cut by moldboard and scarifier combined normally at 2nd gear at full throttle.

3) Creating a bank slope: Grader  can be used for Sloping the bank of road prevents slope failure.

4)Cleaning Ditches: Grader can be used to remove unwanted material from ditch during the bank slope operation.

5)Spreading material: Graders are often used to spread and mix loads.

l Capacities

Different capacities of grader ranges from 
about 60 to 600hp.

Blade size ranges from 2.5 to 7.3 meter.
