Bengaluru - first Wi-Fi city

Now upload photos on Facebook, check mails on smartphone, tweet on go via free Wi-Fi access offered by the Karnataka state government in the city of Bengaluru.

The Economic Times report says that Karnataka state government will offer free wireless data services from next month, that will nail Bengaluru as the first city in the country to offer such a service. 


Former director at Infosys, Mohandas Pai, heads the government formed panel to undertake the idea of Wi-Fi in the city. On a test basis this service will be available for 6 months to determine the viability of the service. Mahatma Gandhi Road and Brigade Road in Bengaluru to get the first form of this service.

"A smartphone revolution is happening in India, but connectivity is still an issue here. We wanted to provide seamless Internet access to people," Mohandas Pai said.

Staircase Light with auto switchoff

          STAIRCASE LIGHT WITH AUTO SWITCH OFF


We are all familiar with the electrical wiring arrangement that connects an electrical bulb with two switches: one at the bottom of a staircase and the other at the top. Wiring is done such that either of the two switches can be used to switch the bulb on or off. In such a wiring arrangement, while climbing up the staircase which is in dark, the switch located at the bottom of the staircase is used to switch on the light. After you have climbed the staircase, you use the switch located there to switch off the light.

In this circuit also, we have two micro-switches—one located at the top and the other located at the bottom of the staircase—that can be pushed and released easily during climb-up from
the bottom of the staircase or climbdown from the top of the staircase. With every push and release of either of the two switches, bulb L1 lights up for a preset time period of, say, 40 seconds, which is considered adequate for climbing up or going down the staircase. The bulb goes off automatically after the set 40 seconds. You can change this ‘on’ time by changing the values of resistor R7 and/or capacitor C4 depending upon your requirement.


Switches S1 and S2 are the two micro-switches, which provide low inputs to the respective de-bouncing circuits. Each de-bouncing circuit is built around two NAND gates connected back to back. The de-bouncing circuits ensure a clean, bounce-free pulse at the output every time the micro-switch is pressed and released. The outputs from the two de-bouncing circuits are ORed using diodes D1 and D2 (1N4001). So every time you press and release either of the micro-switches, you get a positive going pulse at the junction of the cathodes of diodes D1 and D2.


These pulses are used to trigger the monostable circuit built around timer IC2. On the trailing edge of the pulse, the output of the monostable goes high for a time period of 40 seconds. This drives relay-driver transistor 2N2222 (T1) wired as a switch. Relay RL1 gets energised and closes N/O
contacts of the relay, wired in series with the mains and the bulb (L1). Bulb L1 switches off when the relay gets de-energised after 40-second pulse period. Free-wheeling diode D4 (1N4001) protects transistor T1 against transients during relay switch-off operation. The circuit operates off a 9V battery, which gets connected to the circuit through ‘on’/‘off’ switch S3. You can also use regulated 9V power supply. Assemble the circuit on a general purpose PCB and house in a small box. Connect micro-switches S1 and S2 near top and bottom of the staircase through flexible wires and bulb in the middle of the staircase.

Recruit the right person

HOW TO RECRUIT THE RIGHT PERSON FOR THE RIGHT JOB?

Put about 100 bricks in some particular order in a closed Room with an Open window.

Then send 2 or 3 candidates in The room and close the door.

Leave them alone and come back After 6 hours and then analyze The situation.

If they are counting the Bricks.
Put them in the accounts Department.  

If they are recounting them..
Put them in auditing .

If they have messed up the Whole place with the bricks.
Put them in engineering.

If they are arranging the Bricks in some strange order.
Put them in planning.  

If they are throwing the Bricks at each other. 
Put them in operations .

If they are sleeping.
Put them in security.

If they have broken the bricks Into pieces.
Put them in information Technology.

If they are sitting idle.
Put them in human resources.

If they say they have tried Different combinations, yet Not a brick has
Been moved. 
Put them in sales.


If they have already left for The day.
Put them in marketing.

If they are staring out of the Window.
Put them on strategic Planning.

And then last but not least.
If they are talking to each Other and not a single brick Has been Moved.

Congratulate them and put them
In top management.  

Earth laughs in flowers

Nature never wears a mean appearance
