Design elements - Sport fields and recreation

The vector stencils library "Sport fields and recreation" contains 25 shapes for drawing sport fields and recreation plans.
"A pitch is an outdoor playing area for various sports. The term is used in British and Australian English; the comparable term in American English is playing field. In most sports, the official technical term is field of play, although this is not regularly used by those outside of refereeing/ umpiring circles.
In the sport of cricket, the cricket pitch refers not to the entire field of play, but to the section of the field on which batting and bowling take place in the centre of the field. The pitch is prepared differently to the rest of the field, to provide a harder surface for bowling.
A pitch is often a regulation space, as in an association football pitch." [Pitch (sports field). Wikipedia]

The vector stencils library "Semiconductors" contains 22 symbols of rectifiers, diodes, charge transfer and electronic conduction devices, switches, cathodes, transistors, thyristors, and transceivers for semiconductor (SIS) design.
"Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors. Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications. They use electronic conduction in the solid state as opposed to the gaseous state or thermionic emission in a high vacuum.
Semiconductor devices are manufactured both as single discrete devices and as integrated circuits (ICs), which consist of a number - from a few (as low as two) to billions - of devices manufactured and interconnected on a single semiconductor substrate, or wafer. ...
All transistor types can be used as the building blocks of logic gates, which are fundamental in the design of digital circuits. In digital circuits like microprocessors, transistors act as on-off switches; in the MOSFET, for instance, the voltage applied to the gate determines whether the switch is on or off.
Transistors used for analog circuits do not act as on-off switches; rather, they respond to a continuous range of inputs with a continuous range of outputs. Common analog circuits include amplifiers and oscillators.
Circuits that interface or translate between digital circuits and analog circuits are known as mixed-signal circuits.
Power semiconductor devices are discrete devices or integrated circuits intended for high current or high voltage applications. Power integrated circuits combine IC technology with power semiconductor technology, these are sometimes referred to as "smart" power devices. Several companies specialize in manufacturing power semiconductors." [Semiconductor device. Wikipedia]
