La Crosse Technology was founded in 1983 as a grandfather clock distribution company after the founder, Allan McCormick, returned from being stationed in Germany. [ 1 ] La Crosse Technology introduced the radio-controlled clock , commonly (but incorrectly) called an "atomic clock" after the extremely accurate timepiece behind the radio signal ...
WWVB's Colorado location makes the signal weakest on the U.S. east coast, where urban density also produces considerable interference. In 2009, NIST raised the possibility of adding a second time code transmitter, on the east coast, to improve signal reception there and provide a certain amount of robustness to the overall system should weather or other causes render one transmitter site ...
E. Howard & Co. was a clock and watch company formed by Edward Howard and Charles Rice in 1858, after the demise of the Boston Watch Company.The pair acquired some of the material and watches in progress, based upon a lien against the defunct company held by Rice, but they were unable to buy the existing factory or machinery, so they moved to Roxbury.

The clock, just 7 inches high, sat under a rounded glass dome on one of the highest shelves in the library of his family's house in Rochester, N.Y.
Atomic clocks are installed at sites of time signal radio transmitters. [113] They are used at some long-wave and medium-wave broadcasting stations to deliver a very precise carrier frequency. [114] Atomic clocks are used in many scientific disciplines, such as for long-baseline interferometry in radio astronomy. [115]
