An in-ear monitor system has earpieces with haptic metronome actuators. Synchronized metronome vibration pulses, which pose no audible interference to audio monitoring, stimulate the user's ear and or ear canal. A sound engineer or technician from a control console selects or programs the synchronized metronome timing sequence and the sequence is multicast to one or more receiver body packs worn by the performer in the group. The timing sequence can alternatively be selected in response to audio commands spoken by a user wearing the in-ear monitor, or can be based on a beat sensor.

An atomic object confined in a particular region of an atomic object confinement device is cooled using an EIT cooling operation from S to P to D. A controller associated with the atomic object confinement device controls a first steering source and a second steering source to provide a first steering signal and a second steering signal, respectively, to the particular region. The first steering signal is characterized by a first wavelength corresponding to a transition between an S manifold and a P manifold of a first component of the atomic object, and the S to P transition is detuned by a first detuning amount. The second steering signal is characterized by a second wavelength corresponding to a transition between the P manifold and a D manifold of the first component, and the P to D transition is detuned by a second detuning amount. The first detuning amount and the second detuning amount are selected to establish a dark state associated with a two-photon transition between the S manifold and the D manifold.

This invention relates to the field of pulsar timing technology, and more particularly to a comprehensive pulsar timing analysis method and system based on iterative filtering. The method includes combining the timing residuals of pulsars in pairs according to combination rules to form multiple master-slave groups of pulsar timing residuals, and iteratively filtering them using the Vondrak-Cepek filtering algorithm to obtain the corresponding filtered timing residuals. After each round of iterative filtering, the filtered timing residuals output from the previous round of iterative filtering are combined in pairs according to combination rules to obtain updated master-slave groups of pulsar timing residuals, which are then used as input for the next round of iterative filtering, until the total number of filtering iterations is reached, thereby obtaining the comprehensive pulsar timing stability. Compared to a single pulsar, this invention, through multiple rounds of iterative Vondrak-Cepek filtering, establishes a comprehensive pulsar timing for selected millisecond pulsars, which can simultaneously improve both short-term and long-term stability.

A signal generator provides a periodic optical signal as output. The signal generator can be optically coupled to a splitter or other distribution network that transits the optical signal along multiple paths to terminate at different locations and / or for use by multiple electronic circuits. Each path can include a reflector element that reflects a portion of the signal back along the optical signal path. Reflections can be separated by operation of a circulator and photodiode. Output of the photodiode can be used to adjust phase and / or amplitude of optical signals traversing each optical signal path such that each electronic circuit receives an in-phase reference signal as input.

The invention relates to an analog diving watch with two concentric rotary bezels (12, 13) that allow immersion time and ascent time to be controlled independently and simultaneously. The first bezel (13) includes a mark (13') for setting the time from the start of immersion up to the expected moment of the start of the ascent; the second bezel (12) has a mark (12') to indicate the minimum time needed to complete the ascent safely. Both bezels are preferably regressive (move anticlockwise), allowing the remaining time to be seen at each stage. Optionally, the watch includes a chronograph with an additional minute hand (8). The invention improves safety by keeping the diver informed, without needing underwater manipulation or mental calculations.
