2. LED Bails.
The bails are powered by hidden low voltage batteries. They each contain a microprocessor that detects when contact between the bails and the stumps has been broken. The bails are illuminated within 1/1000th of a second. ... The microprocessors then send a radio signal to the stumps which also light up.

3. Speed gun
A speed gun (also radar gun) is a device used to measure the speed of ball through by bowler. It measures the speed of the objects at which it is pointed of the returned radar signal caused by the Doppler Effect whereby the frequency of the returned signal is increased in proportion to the ball's speed.
