Abstract: An Electronic Shelf Label (ESL) management server and a method for controlling the ESL management server are disclosed. An ESL management server for compressing an image to be displayed on an external display device of the ESL system comprises a communication unit obtaining an image including product information; and a processor applying a first pre-processing process to the image, chain coding the image to which the first pre-processing process has been applied, encoding a chain code and a chain code table obtained as a result of the chain coding into a bitstream, generating a compressed image file using the bitstream, and transmitting the compressed image file to an external display device through the communication unit, where the first pre-processing process converts data with a high local correlation within the image into a small integer but converts data with a small local correlation within the image into a large integer.

Abstract: A driving device includes a first driving element and a first flexible structure. The first driving element includes a first wire extending in a first direction and includes a shape memory alloy. The first flexible structure has a certain width in a second direction perpendicular to the first direction, and when the first wire contracts in the first direction, the first flexible structure has a height increasing in a third direction perpendicular to both the first direction and the second direction. The driving device further includes a second driving element including a second wire and a second flexible structure, the second wire extending in the first direction and including a shape memory alloy. The second flexible structure has a certain width in the second direction, and when the second wire contracts in the first direction, the second flexible structure has a height increasing in the third direction.
