Abstract: The present disclosure relates to an extrusion nozzle apparatus and a method for extruding a thermoelectric material using the extrusion nozzle apparatus. An extrusion nozzle apparatus according to one embodiment of the present disclosure comprises: an inlet introducing material; an outlet discharging the input material; and a discharge pipe formed in a multi-stage shape including a plurality of stages, wherein the input material is pressurized inside the discharge pipe and moves in a first direction from the inlet toward the outlet. The cross-sectional area of the plurality of stages in a direction perpendicular to the first direction progressively decreases from the inlet to the outlet. Accordingly, the thermoelectric performance of a thermoelectric material may be improved, and production cost and production time may be reduced.

Abstract: A method for identifying traffic information includes receiving traffic data including a first identifier, information that is encoded, and information corresponding to a field indicative of an encoding scheme. The first identifier enables a determination of a type of information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining encoding information based on the field indicative of an encoding scheme included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a field indicative of an encoding scheme. The method further includes identifying the information that is encoded based on the determined encoding information.
