Abstract: The present invention relates to a people counter using a TOF camera and a method of counting people, and more particularly, to a people counter using a TOF camera that can easily check and count objects corresponding to people by filtering objects moving in an image on the basis of depth information obtained by the TOF camera, and a method of counting people. According to the present invention, it is possible to easily revise depth information and size information of an object, which are obtained by a TOF camera disposed on a ceiling, into actual depth and size information, and to ensure reliability in counting people without complicated setup and operation by providing the information so that an object corresponding to a person can be easily recognized and counted from image information obtained by filtering the information into depth information of a person.

Abstract: In a compressor including a sealed casing respectively communicating with a suction pipe and a discharge pipe; a cylinder assembly disposed in the sealed casing and having a suction path and a discharge path; a Z-plate partitioning the internal space of the cylinder assembly into plural compression spaces and sucking, compressing and discharging gas while being rotated by a motor part; a vane contacted to the both surfaces of the Z-plate and partitioning each compression space into a suction region and a compression region while performing a reciprocating motion; and a discharge muffler covered the both sides of the cylinder assembly and lowering noise of discharged gas, a compressor comprises at least one oil returning member installed on a discharge route between the discharge path of the cylinder assembly and the discharge pipe of the sealed casing in order to filter oil flowing with gas.

Abstract: A compressor includes a cylinder assembly which is positioned inside a hermetic vessel having a suction flow path and discharging flow path, a Z-plate for dividing an inner space into a plurality of compression spaces in the cylinder assembly, rotating by a motor part so that gas is sucked, compressed and discharged, and a vane for dividing the respective compression spaces into a suction region and compression region, performing a reciprocating movement being contacted on both surfaces of the Z-plate. In addition, an oil slot for inflowing oil into the cylinder assembly is formed on a side surface of the vane. Therefore, friction generated at a sliding portion inside of the cylinder assembly can be reduced and performance deterioration of the compressor caused by operation noise and friction resistance of the compressor can be prevented.
