The control utilizes a decaying dither of the optical path length which decays from a large initial dither amplitude.

Any undesirable effects introduced by the dithering signal are removed by processing the gyroscope data over an entire cycle of the dithering signal.

The amplitude is fine tuned by applying a phase dither and adjusting the amplitude until effects of the dither are minimized.

The tremor signal is analysed over a period of time, and an alarm is generated when a change in the physiological tremor signal indicative of the onset of hypoglycaemia in the subject is detected.

After the paroxysmal phase, the tremor signal decreases.

A portable sensor worn by a subject is used to detect a physiological tremor signal.

There is NO longer a Harmonic Tremor signal indicating an ongoing eruption.

Finally, a threshold circuit (47a-c) compares the filtered acceleration signal to a predetermined threshold voltage, and produces an earthquake detected signal indicative of the comparison result.

The SLS release happened while the tremor signal remained low.

The first electromagnet (2) and the second electromagnet (1) are connected with an electromagnetic control device (6) which includes a receiver (5) for earthquake signal.

the tremor signal seems to have subsided a little unless IGN did some rescaling of the graph.

The invention preferably includes means for reinstating oscillatory dither when the applied rate exceeds a higher control rate limit defined in both senses of rotation.

The initial eruptive event was associated with a seismic signal which lasted for approximately 13 minutes.

PVMBG reported that a phreatic eruption at Agung began at 1705 on 21 November, following a low-frequency tremor signal.

Agung | Bali (Indonesia) : PVMBG reported that a phreatic eruption at Agung began at 1705 on 21 November, following a low-frequency tremor signal.

During the morning of 29 October a seismologist noted a tremor signal which increased in amplitude during the afternoon and evening.
