Abstract: A virtual reality apparatus comprising: i) a plurality of sensors for detecting objects in the vicinity of a user of the virtual reality apparatus; and ii) a controller coupled to the plurality of sensors and configured to determine that an object has been detected. The controller determines a direction of the detected object with respect to the user. The controller generates a glowing region in a virtual reality image being viewed by the user. The location of the glowing region in the virtual reality image notifies the user of the direction of the detected object. The controller generates an audible notification in response to detection of the detected object and determines a distance of the detected object with respect to the user.

Abstract: Disclosed is a method for manufacturing precision parts through hot isostatic pressing using a metal core manufactured through metal rapid prototyping to manufacture a turbine blisk for driving a turbo pump of a liquid rocket. The method includes: manufacturing a metal core that has an internal vacant space having the same shape as the precision parts, using rapid prototyping; putting the metal core in a housing; filling an inside of the housing with heat resistant steel powder and creating a vacuum state in the housing; treating the housing under high temperature and pressure to produce heat resistant steel; removing the housing and a portion of the heat resistant steel to expose a portion of the metal core; performing etching to remove the exposed metal core; and removing only a portion of the heat resistant steel through mechanical machining, wherein the remaining portion corresponds to the shape of the precision part.

Abstract: A continuous butt welding method using plasma and laser, and a method for fabricating a metal tube using the butt welding method are disclosed. The butt welding method conducts a laser welding and a plasma welding together against an object to be welded, which has a very narrow butt space. In particular, the plasma is prior to the laser so that the object is preheated by the plasma, and then a preform is melted by a laser beam in order to accomplish the major welding. In addition, a metal sheet is bent to have a circular section so that its both ends are faced with each other, and then the faced both ends are welded using the aforementioned butt welding method, thereby fabricating a metal tube. The butt welding method and the metal tube fabricating method mentioned above remarkably improve a welding speed and productivity of metal tube.
