The ClickStart (with the slogan My First Computer) is an educational computer system created for children aged between 3 and 6 years (toddler to kindergarten) by LeapFrog Enterprises and was introduced in 2007. It is LeapFrog's second home console, and the first to come with its own games.
The Fly, released in 2005, [2] is a customizable pen that is intended to assist children with schoolwork. There are several bundled and add-on applications available, including a notepad, calculator, language and writing assistant, and educational games; many of these require the use of a small cartridge that can be inserted into a port built into the rear of the pen.

A further form of partial dual ignition (such as on the Honda VT500) is for each cylinder to have a single HT coil which sends the current to one plug and completes the circuit via the second plug, rather than via the earth. This system requires a voltage sufficient to jump both plug gaps, but an advantage is that if one plug fouls, the fouled ...
Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
The lack of moving parts compared with the mechanical system leads to greater reliability and longer service intervals. A variation coil-on-plug ignition has each coil handle two plugs, on cylinders which are 360 degrees out of phase (and therefore reach top dead center (TDC) at the same time); in the four-cycle engine this means that one plug ...
The LeapPad Explorer was the first release in a new line of LeapPad products after the discontinuation of the original LeapPad line by LeapFrog Enterprises, Inc. [2] [3] LeapPad Explorer was released on August 15, 2011. New versions of the LeapPad Explorers were released in July 2012. [4]
Spark-ignition engines are commonly referred to as "gasoline engines" in North America, and "petrol engines" in Britain and the rest of the world. [1] Spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline, such as autogas (), methanol, ethanol, bioethanol, compressed natural gas (CNG), hydrogen, and (in drag racing) nitromethane.
