For vehicles where the above formula cannot be applied (e.g. electric vehicles), the tax horsepower is derived from the effective engine power (which is defined by law as the maximum power that the engine can provide after being used at full power from 30 minutes, which is normally lower than the rated engine power).
An electric model, the Mercedes Euklid 30, was released circa 1945, though it may not have been the company's first electric calculator. In the 1960s, another electric model was released under the name "Cellatron." A Mercedes-Euklid Cellatron on Display at Berlin Vintage Computer Festival.
By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries. The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. It could add ...
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, [1] 2016, [2] 2017, [3] and 2023 [4] versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid ...
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Some adding machines were electromechanical – an old-style mechanism, but driven by electric power. Some "ten-key" machines had input of numbers as on a modern calculator – 30.72 was input as 3, 0, 7, 2. These machines could subtract as well as add. Some could multiply and divide, although including these operations made the machine more ...
