Abstract: Disclosed are an optical stimulation probe structure having a probe body inserted into a subject, a fixing body that fixes the probe body and a light radiator that transmits an optical signal to the probe body, wherein the probe body is made of an optical transmission material capable of transmitting an optical signal, such that the optical signal transmitted from the light radiator is transmitted through the probe body to the subject, and a method for manufacturing the same.

Abstract: The tactile display device of the present disclosure includes: an actuator which is movable in a vertical direction when an electric current or a pneumatic force is applied thereto; and a body made of flexible material and having a receiving unit for receiving the actuator and a fluid channel allowing a pneumatic force from an outside to be transferred to the receiving unit, wherein a membrane made of flexible material and capable of vertical displacement is attached to an upper end of the receiving unit of the body, and the actuator is coupled to a lower portion of the membrane so that the membrane and the actuator have the same vertical displacement.

Abstract: Disclosed herein is a bidirectional moving micro-robot system. The bidirectional moving micro-robot system has a first body having a plurality of legs foldably/unfoldably connected thereto, a second body having a plurality of legs foldably/unfoldably connected thereto and a connection member having both end portions respectively connected to the first and second bodies. In the bidirectional moving micro-robot system, the length of the connection member exposed between the first and second bodies is extended or contracted.

Abstract: A printing apparatus in which a general command is converted to a real-time command depending on the needs, allowing fast status analysis and error recovery with fewer number of control commands without inconveniencing the user, a control method therefor, and a data processing apparatus using the printing apparatus. In the printing apparatus or the data processing apparatus including the same which is operated by transmission of command data and print data from a host computer, general data usually processed in order is converted to a real-time command using a real-time command identifier. The printing apparatus receives the data with the real-time command identifier and processes the command or print data designated by the real-time command identifier. The apparatus and method allow using a fewer number of commands to execute various controls.
