A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time.

Which outdoor clocks are best? An outdoor clock is perfect for all those patio-loving, balcony-adoring, garden-making people out there. Putting aside the obvious aesthetic values of a well ...

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

【Reliable Atomic Clocks】: Ensures exact time accuracy by syncing with the atomic clock via radio signals. 【Whisper-Quiet Movement】: Silent sweep second hand ensures a peaceful ...

Atomic clocks ... autonomous sensor networks, and unmanned vehicles due to its compact size, low power consumption, and high precision. In applications, precise clocks are needed for functions ...

This technology, called the 'microcomb chip,' could make optical atomic clocks, the most precise timekeepers in the world, compact enough for everyday use. Credit: Kaiyi Wu This breakthrough could ...

The Onvis outdoor motion sensor, built with Thread technology and an IP66 rating, is made to work great in both areas. If you want to trigger HomeKit devices based on motion outside, read on to ...

A low-noise chip-scale atomic clock (LN-CSAC), the SA65-LN from Microchip, features a profile height of less than 0.5 in. (12.7 mm). Aimed at aerospace and defense applications where size, weight, and ...

Microchip has combined a chip-scale caesium atomic clock for good accuracy with a ovened crystal oscillator for good phase noise, in a through-hole package measuring 0.4 x 50.4 x 12.7mm (2 x 2 x ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

Such a device would greatly surpass the capabilities of atomic clocks, which define the span of a second through controlled energy jumps in atoms’ electrons and are currently the pinnacle of ...
