Single point positioning with precise orbits and clocks was recently introduced in the GPS community.
As single point positioning with precise orbits and clocks is new to the GPS community, it is worthwhile to show some results demonstrating its capabilities compared to use of broadcast orbits.

 Collecting Antique Clocks: Conversion Lantern Clocks and Richard Smith, by Brian Loomes, writer and dealer
Single-handed clocks (as lantern clocks were) needing frequent winding became outmoded and by the mid to late nineteenth century were pretty well obsolete.
Today conversion lantern clocks, though nowhere near as valuable as 'unconverted' ones (which themselves of course have usually been converted anyway to different forms of escapement from their original form), are highly saleable to a far wider public, who enjoy the clock for what it is.
The movement of a spring clock is more subject to interference by dirt and dust than the old weight-driven lantern clock with its massive wheels which, which usually chugged away happily in mud-floored houses regardless of floating straw and chicken feathers.

 ScienceDaily: NIST Unveils Chip-Scale Atomic Clock
The "physics package" of the chip-scale atomic clock includes (from the bottom) a laser, a lens, an optical attenuator to reduce the laser power, a waveplate that changes the polarization of the light, a cell containing a vapor of cesium atoms, and (on top) a photodiode to detect the laser light transmitted through the cell.
The new clock is based on the same general idea as other atomic clocks such as the NIST-F1 fountain clockmeasuring time by the natural vibrations of cesium atoms, at 9.2 billion "ticks" per secondbut uses a different design.
In the chip-scale clock, cesium vapor is confined in a sealed cell and probed with light from an equally small infrared laser, which generates two electromagnetic fields.

 History of the Black Forest Cuckoo Clock
Old clocks, original drawings of the first clocks etc. are still used and modified as patterns for new models, but the cuckoo clock in its basic form is 200 years old and has survived until now.
A cuckoo clock is typically a pendulum clock striking the hours using small bellows and whistles that imitate the call of the cuckoo bird and hit on a wire gong.
The "framed clock", as its name suggests, had a strong wooden frame and a wide painted inner section to which the clock face was attached.

 Xcell Journal Online -- Virtex-4 Xesium article - Issue 52
Clocks must maintain their duty cycle, which is especially important in double-data-rate designs where data is clocked on the rising as well as on the falling clock edge.
All global clock inputs have dedicated fast routing to the corresponding global clock buffer, which can also be used as a clock-enable circuit or a glitch-free multiplexer.
A global clock buffer is often driven by a digital clock manager (DCM) to eliminate the clock distribution delay, or to adjust its delay relative to another clock.

 Mechanisms of Aging: Introduction
Contrary to popular belief, aging is not a single process, but rather a group of processes that involve different mechanisms.
Secondly, there seems to be a "central clock," located in the brain, which paces both the development and aging of the organism.
There are other types of aging clocks, such as the clock shutting down reproductive function in women (menopause), although they seem to be at least somewhat dependent on the pace of central and cellular clocks.

 Mercury Atomic Clock Keeps Time with Record Accuracy
The improved version of the mercury clock is the most accurate to date of any atomic clock, including a variety of experimental optical clocks using different atoms and designs.
An optical atomic clock has three components: an atom that switches from one energy level to another when probed by a laser at a well-defined optical frequency; the laser used to induce this transition; and a counter that faithfully records each oscillation per unit time (the ticks) of the probe laser.
The NIST mercury clock is unusual in part because of the method for stabilizing the ultraviolet laser used to probe the clock transition.

 Keeping time with a mercury atom

An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a "fountain" of cesium atoms.
The clock projects are led by different scientists, in different labs, on different campuses.) The strontium clock is a newer technology that is at a much earlier stage of development, and correspondingly, has much lower performance than the mercury clock.

 Lattice trap improves optical clocks - optics.org   (Site not responding. Last check: )
Optical clocks, based on either single trapped-ions or cooled neutral atoms, are a promising successor to the atomic clock but are hard to stabilize.
The lattice trapping enhances the clock's stability by preventing troublesome collisions between the atoms that plague traditional neutral atom clocks.
At the same time the large number of atoms gives a much stronger signal than single ion clocks which emit a weak signal that needs to be averaged over a long time period.

Einstein of course was aware that his clocks were not synchronized, but this is obviously not something one would advertise about one's theory, so Einstein never explicitly stated (at least not publicly) that his clocks are not synchronized.
Intrinsic clock slowing is allowed because all that is required is a steady clock rhythm, slowed or not.
All that is needed are constant and equal belt speeds relative to the clocks, and this is guaranteed by the fact that the timing marks (on the shafts' perimeters) travel equal distances in equal times (per the same clock) with the coincident shaft faces being equal distances.
