Shortt's breakthrough in 1920 came with the development of a clock system, inspired by the work of R.J. Rudd of Croydon, [5] championed by Hope-Jones, in which the task (each thirty seconds) of unlocking the impulse to an otherwise free pendulum was taken on by a separate slave clock, which in turn was corrected (as part of the same operating ...
On the left is the primary pendulum in its vacuum tank. The Shortt–Synchronome free pendulum clock is a complex precision electromechanical pendulum clock invented in 1921 by British railway engineer William Hamilton Shortt in collaboration with horologist Frank Hope-Jones, [1] and manufactured by the Synchronome Company, Ltd., of London.

A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is an approximate harmonic oscillator : It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates.
TimeTrax is a software and hardware platform from Time Trax Technologies Corp. which allows audio recording from satellite radio, Internet streaming and traditional radio broadcasts. The company is best known for its disruptive innovation and leading role it played in the transformation of the business model of the music industry.
When interpreting emotion and other qualities in music, performers seldom play exactly on every beat. In a musically expressive performance, the pulse generally does not align with the clicks of a metronome. [2] [3] This has led some musicians to criticize use of a metronome, because "musical time is replaced by clock time". [4]
The torsion pendulum has a period of precisely one minute; thirty seconds to rotate in one direction and thirty seconds to return to the starting position. This is thirty times slower than the 0.994 m (39.1 in) seconds pendulum typically found in a longcase clock, where each swing (or half-period) takes one second.

A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
