Using analytical signals and synchronous detection to obtain signals of skin galvanic activity on alternating current

Biomedical Radioelectronics
The interest in the skin galvanic channel for obtaining information about a person's condition is related to the fact that these signals mainly arise as a result of higher nervous activity. This makes them interesting in a number of practical applications, such as lie detectors, devices for monitoring the ability of operators, etc.

Synchronous alternating current motor and mechanical vibrating system maintained by a thermionic valve at the frequency of the vibrating system

Proceedings of the Physical Society, 1926
The design of a chronograph which will give a time trace subdivided into units and fractional units requires the association of a rotating system and a vibrating or time-keeping system. It a low-frequency vibrating system be employed, the rotating system, although keeping good average time, may show exaggerated errors in unit subdivisions due to ...

ALTERNATING CURRENT (AC) SYNCHRONIZATION FOR LOAD RESTORATION

2015
Among other things, one or more techniques and/or systems are provided for synchronizing one or more direct current (DC)to alternating current (AC) power sources (e.g., a DC power source coupled to an inverter) for restoration of power to a load. That is, responsive to a grid fault of a grid used to supply power to a load over a common bus, the common ...

Automatic control systems of rectifier-loaded synchronous alternators and of D.C. motors in the constant-current loop aboard a pipelaying barge

IFAC Proceedings Volumes, 1974
Zusammenfassung Der vorliegende Aufsatz beschreibt den Signalflus der Regeleinrichtungen, die fur die Speisegeneratoren und die Antriebsmotoren in einem Konstant-Strom-Kreis an Bord eines grosen Rohrverlegers konzipiert wurden. Einleitend wird die Anordnung der speisenden und verbrauchenden Komponenten innerhalb des Konstant-Strom-Systemes erlautert.
