Abstract: In a method for automatic color wheel calibration in a projector, the color wheel includes three primary colors and a non-primary color. The method includes: enabling the projector to project the non-primary color, and measuring first optical physical amounts of the projected non-primary color; enabling the projector to project a combination color of the three primary colors having respective color level values, measuring second optical physical amounts of the projected combination color, and adjusting the respective color level values of the three primary colors according to respective values of differences between the first optical physical amounts and the second optical physical amounts; and repeating the above steps until each of the values of differences approximates zero, thereby obtaining color level values for the three primary colors to produce a combination color matching the non-primary color.

Abstract: There are disclosed a system and a method for measuring reflectance of an object. The system for measuring reflectance of an object according to the present invention includes: a light source unit including a light source irradiating light to the object; a light source position adjusting unit that adjusts a position and a direction of the light source unit; a light receiving unit that acquires image data by detecting light reflected on the object; and a reflectance acquiring unit that acquires the reflectance of the object from the image data. According to the present invention, it is possible to more precisely acquire the reflectance of the object within a shorter time.

Abstract: A debugger attaches to a parallel process that is executing simultaneously at various nodes of a computing cluster. Using a shim, executing at each node, to monitor each of the processes, the parallel process is debugged such that neither the process or the particular message passing system implemented on the cluster, needs to know of the existence or details regarding the debugger.

Abstract: A curling iron includes a steam generator, a heating unit, a condensed water discharging unit, and a check valve. The steam generator is configured to generate steam using water. The heating unit is configured to receive steam from the steam generator and transfer heat of the steam to a target material. The condensed water discharging unit is configured to collect condensed water from the heating unit and to return the condensed water to the steam generator for recycling the condensed water, and the condensed water discharging unit is disposed between the heating unit and the steam generator. The check valve is configured to prevent the steam in the heating unit to flow into the steam generator and to allow the condensed water in the heating unit to flow into the steam generator, and the check valve is disposed between the condensed water discharging unit and the steam generator.

Abstract: Provided are an equipotential ground system and a method of constructing the same capable of equalizing potential of all positions when the ground system is configured in a mesh manner. The equipotential ground system includes: a mesh having a plurality of row lines, and a plurality of column lines installed to cross the row lines to form intersection parts electrically connected to the row and column lines; first ground rods connected to corners of the mesh; and a plurality of second ground rods having a larger ground resistance than the first ground rods and connected to the outermost intersection parts of the mesh, which are disposed between the first ground rods.

Abstract: A system, method, and computer readable medium for passive optical network rogue optical network unit diagnostics, comprises, detecting an alarm of a network, correlating the detected alarm to a bandwidth map, and selectively disabling an optical network unit upstream to the detected alarm on the bandwidth map for a pre-determined interval.

Abstract: The object of this invention is to provide a curling iron using heated fluid as its heat source. The curling iron of the present invention is comprised of a fluid heating unit, a heating unit, and curling tongs. Since the curling iron uses heated fluid as its heat source for heating hair, the curling iron uses heated fluid as its heat source for heating hair, the curling iron maintains a constant temperature capable of accomplishing a desired curling effect and prevents an excessive increase in its temperature so as to prevent damage to the hair.

Abstract: The object of this invention is to provide a curling iron using heated fluid as its heat source for heating hair. The curling iron of the present invention is comprised of a fluid heating unit which heats the fluid to produce steam (100) used as the heat source, a heating unit which transfers heat of the steam to hair, and thereby curls the hair, and curling tongs which support the heating unit so as to allow the heating unit to heat the hair while the curling tongs grasp the hair. Since the curling iron uses heated fluid as its heat source for heating hair, the curling iron uses heated fluid as its heat source for heating hair, the curling iron maintains a constant temperature capable of accomplishing a desired curling effect and prevents an excessive increase in its temperature so as to prevent damage to the hair.

Abstract: A system for securing an application for execution in a computer. In one embodiment, a preprocessor module modifies an application binary such that the application invokes an interception module in response to invoking certain system calls. The interception module prevents the application from adversely affecting the operating of a computer that is executing the application. Furthermore, the interception module protects the contents of the application from improper access by a user of the computer. For example, the interception module transparently encrypts all files that are used by the application such that a user of the computer cannot improperly access these files.
