NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined and is controlled by the National Marine Electronics Association (NMEA).
This electric field is generated by means of a specialised electric organ consisting of modified muscle or nerves. [13] Animals that use active electroreception include the weakly electric fish , which either generate small electrical pulses (termed "pulse-type"), as in the Mormyridae, or produce a quasi- sinusoidal discharge from the electric ...
p–n junctions represent the simplest case of a semiconductor electronic device; a p-n junction by itself, when connected on both sides to a circuit, is a diode. More complex circuit components can be created by further combinations of p-type and n-type semiconductors; for example, the bipolar junction transistor (BJT) is a semiconductor in ...
P-N junction The boundary between two differently doped regions of a semiconductor. polarization density A measure of the increase of the intensity of an electric field over that in free space, owing to the separation of atomic-scale electric dipoles. polyphase coil A coil intended for connection to a polyphase power supply. polyphase system
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
right fish tail Sometimes used for “relation”, also used for denoting various ad hoc relations (for example, for denoting “witnessing” in the context of Rosser's trick ). The fish hook is also used as strict implication by C.I.Lewis p {\displaystyle p} ⥽ q ≡ ( p → q ) {\displaystyle q\equiv \Box (p\rightarrow q)} .
It may be the entity who first designed the part (that is, the ODA), but today it is also likely to be a designated successor entity, owing to mergers and acquisitions (M&A) activity (e.g., ODA company was bought by CDA company); contract letting (e.g., an Army engineering department ODA turns over the design activity to the prime contractor ...
The elephantnose fish is a weakly electric fish which generates an electric field with its electric organ, detects small variations in the field with its electroreceptors, and processes the detected signals in the brain to locate nearby objects.
