Abstract: Provided is an apparatus for measuring a wafer. The apparatus may include a chuck disposed on a stage and a plate connected with the stage, a horizontal frame configured to support a wafer, and a vertical frame connecting the plate and the horizontal frame. The apparatus may further include first to third adsorption portions connected with the horizontal frame and configured to adsorb the wafer, a support bar penetrating through the chuck and extending in a first direction and a beam irradiator connected to the support bar and disposed between the plate and the horizontal frame. The beam irradiator may be configured to irradiate a beam on the wafer. The apparatus may further include a detector on an opposite side of the horizontal frame from the beam irradiator and configured to receive the beam after it has penetrated through the wafer.

Abstract: The present invention relates to a direction-controllable drug injection catheter. According to the present invention, provided is the catheter extending along a central axis “A” including a drug injection part in which a drug injection channel has been formed; a channel opening and closing means which opens and closes the drug injection channel; and a steering structure which is rotationally asymmetric with respect to the central axis “A” and varies according to a pressure change of the drug injection channel for the purpose of steering.

Abstract: A flexible server system includes an embedded processor, one or more processor boards, one or more storage boards, and a switch including a plurality of ports. The embedded processor, the one or more processor boards, and the one or more storage boards are connected to a corresponding one of the plurality of ports. The embedded processor, the one or more processor boards, the one or more storage boards, and the switch each include a peripheral component interconnect express (PCIe) interface. The one or more processor boards and the one or more storage boards are connected to the switch through connectors where each of the corresponding connectors have a same size. The embedded processor controls the switch to route a packet from one of the plurality of ports to another one of the plurality of ports.
