Generation of primes. In computational number theory, a variety of algorithms make it possible to generate prime numbers efficiently. These are used in various applications, for example hashing, public-key cryptography, and search of prime factors in large numbers. For relatively small numbers, it is possible to just apply trial division to ...
PIN diode. A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts . The wide intrinsic region is in contrast to an ordinary p–n diode.
Chemical oxygen generator. A chemical oxygen generator is a device that releases oxygen via a chemical reaction. The oxygen source is usually an inorganic superoxide, [1] chlorate, or perchlorate. Ozonides are a promising group of oxygen sources, as well. The generators are usually ignited by a firing pin, and the chemical reaction is usually ...
Intersil ICL8038. The ICL8038 waveform generator was an Integrated circuit by Intersil designed to generate sine, square and triangular waveforms, [1] based on bipolar monolithic technology involving Schottky barrier diodes. [2] ICL8038 was a voltage-controlled oscillator [3] : 434 capable of producing frequencies between a millihertz and 100 ...
ID-1. The Bulgarian identity card ( Bulgarian: лична карта, lichna karta, lit. 'personal card') is a compulsory identity document issued in Bulgaria. The document is issued by the police on behalf of the Ministry of Interior and is the main form of identification on the territory of the Republic of Bulgaria. All Bulgarians are obliged ...
The result is a circuit that outputs a 1 when the number of 1s at its inputs is odd, and a 0 when the number of incoming 1s is even. This makes it practically useful as a parity generator or a modulo-2 adder. For example, the 74LVC1G386 microchip is advertised as a three-input logic gate, and implements a parity generator.

v. t. e. In mathematics the spin group, denoted Spin ( n ), [1] [2] is a Lie group whose underlying manifold is the double cover of the special orthogonal group SO (n) = SO (n, R), such that there exists a short exact sequence of Lie groups (when n ≠ 2 ) The group multiplication law on the double cover is given by lifting the multiplication on .
A personal unblocking key ( PUK ), sometimes called personal unblocking code ( PUC ), is used in SIM cards to reset a personal identification number (PIN) that has been lost or forgotten. Most mobile phones offer the feature of PIN protection. After switching on the phone, if the PIN security function is active, the user is required to enter a ...
