Several mechanical counters Mechanical counter wheels showing both sides. The bump on the wheel shown at the top engages the ratchet on the wheel below every turn. Early IBM tabulating machine using mechanical counters. Mechanical counters are counters built using mechanical components. They typically consist of a series of disks mounted on an ...
In poetry, metre (Commonwealth spelling) or meter (American spelling; see spelling differences) is the basic rhythmic structure of a verse or lines in verse.Many traditional verse forms prescribe a specific verse metre, or a certain set of metres alternating in a particular order.
Mechanical tally counters. A tally counter is a mechanical, electronic, or software device used to incrementally count something, typically fleeting. One of the most common things tally counters are used for is counting people, animals, or things that are coming and going from some location.
Action describes energy summed up over the time a process lasts (time integral over energy). Its dimension is the same as that of an angular momentum.. A phototube provides a voltage measurement which permits the calculation of the quantized action (Planck constant) of light.
Hubodometer Veeder-Root Hubodometer Veeder-Root Original Veeder Counter Veeder Company Cyclometer Poster 1900. A hubometer (from hub, center of a wheel; -ometer, measure of) or hubodometer, is a device mounted on the axle of any land vehicle to measure the distance traveled by a vehicle based on the rotations of the wheel hub.
The counter has gears that drive a mechanical digital counter. One count typically corresponds to about 1/20 of a wheel revolution (this varies if a different gear ratio is used); this provides a resolution of about 10 cm in course length, although overall accuracy, depending on calibration and other factors, is lower, but normally better than ...
Hamman Manus R mechanical computer, produced in Germany by the DeTeWe company between 1953 and 1959. A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment ...
Mechanical current meters are mostly based on counting the rotations of a propeller and are thus rotor current meters. A mid-20th-century realization is the Ekman current meter which drops balls into a container to count the number of rotations.
