The Elka 22 was the second Bulgarian electronic calculator; it was released in 1966 and its serial production began in 1967 in the town of Silistra. Weighing 8.5 kilograms (18.7 pounds), the Elka 22 has 3 registers and operates with 12 decimal digits. Addition speed is 0.3 seconds per operation, and division speed is 0.5 seconds. Its power consumption is 35 watts. [1] This calculator has a plastic case, a nixie tube display and its technology is based on numerous phenol boards populated with hundreds of discrete transistors, diodes and resistors, not unlike other calculator models developed around the mid-1960s. The machine used a magnetic-core memory.

In photography, exposure value (EV) is a number that represents a combination of a camera's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV. Exposure value is also used to indicate an interval on the photographic exposure scale, with a difference of 1 EV corresponding to a standard power-of-2 exposure step, commonly referred to as a stop.

When setting photoflash exposures, the guide number (GN) of photoflash devices is a measure photographers can use to calculate either the required f‑stop for any given flash-to-subject distance, or the required distance for any given f‑stop. To solve for either of these two variables, one merely divides a device's guide number by the other.

The Porsche 911 GT2 is a high-performance, track-focused sports car built by the German automobile manufacturer Porsche from 1993 to 2009, and then since 2010 as the GT2 RS. It is based on the 911 Turbo, and uses a similar twin-turbocharged engine, but features numerous upgrades, including engine enhancements, larger brakes, and stiffer suspension calibration. The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 is the most expensive and fastest model among the 911 lineup.
