  2. Delay box - Wikipedia

    en.wikipedia.org/wiki/Delay_box

    Some drag race cars now use 16 volt DC systems, in such a scenario the delay box has to be capable of working properly from 16 volts DC, as well as 12 volts DC. The race car driver holds an electrical pushbutton switch depressed with a finger or a thumb of his right or left hand until he sees a specific desired visual cue.

    Use memory buttons to ensure that operations are applied in the correct order. Use the special buttons ± and 1/x, that do not correspond to operations in the formula, for non-commutative operators. Mistakes can be hard to spot because: For the above reasons, the sequence of button presses may bear little resemblance to the original formula.

    A master control console (MCC) provides office technicians access to the switch through the processor peripheral interface (PPI). [2] Early versions used the same 1A processor as the contemporaneous improved 1AESS switch. All existing switches have been subsequently upgraded to use the 1B processor.

  6. Nonblocking minimal spanning switch - Wikipedia

    en.wikipedia.org/wiki/Nonblocking_minimal...

    The basic mathematical property of Strowger switches is that for each input to the switch, there is exactly one output. Much of the mathematical switching circuit theory attempts to use this property to reduce the total number of switches needed to connect a combination of inputs to a combination of outputs.

    The prisoners enter the room, one after another. Each prisoner may open and look into 50 drawers in any order. The drawers are closed again afterwards. If, during this search, every prisoner finds their number in one of the drawers, all prisoners are pardoned. If even one prisoner does not find their number, all prisoners die.

  8. Monty Hall problem - Wikipedia

    He offers the option to switch only when the player's choice happens to differ from his. Switching wins the car half of the time. The host opens a door and makes the offer to switch 100% of the time if the contestant initially picked the car, and 50% the time otherwise. [9] Switching wins ⁠ 1 / 2 ⁠ the time at the Nash equilibrium.

  9. Omega network - Wikipedia

    en.wikipedia.org/wiki/Omega_network

    The next-most significant bit of the destination address is used to select the output of the switch in the next stage, and so on until the final output has been selected. For example, if a message's destination is PE 001, the switch settings are: upper, upper, lower. If a message's destination is PE 101, the switch settings are: lower, upper ...
