Abstract: A method and apparatus for displaying a medical image of an object. A user input is received to select at least one position in a 2D medical image generated from volume data representing the object. A space region in the volume data is determined, which includes the selected position, where the space region is based on brightness of voxels included in the volume data. A 3D medical image is generated and displayed, representing the determined space region by performing volume rendering on the volume data. The space region may be a region of an organ, tissue, tumor, etc., of the overall object, which includes the position selected on the 2D image.

Abstract: An interactive system for interacting with a sentient being. The system includes a robotic companion of which the sentient being may be a user and an entity which employs the robot as a participant in an activity involving the user. The robotic companion responds to inputs from an environment that includes the user during the activity. The robotic companion is capable of social and affective behavior either under control of the entity or in response to the environment. The entity may provide an interface by which an operator may control the robotic companion. Example applications for the interactive system include as a system for communicating with patients that have difficulties communicating verbally, a system for teaching remotely-located students or students with communication difficulties, a system for facilitating social interaction between a remotely-located relative and a child, and systems in which the user and the robot interact with an entity such as a smart book.

The actuator allows the reflection minor to move. The controller obtains distance information from a signal detected by the light-receiving unit, and obtains location information from the actuator.

Abstract: A method and apparatus for controlling a wavelength tuning of an optical source in an optical communication system. An operating temperature of an optical source is controlled and monitored to shorten a wavelength tuning time of the optical source generated in an optical source generator. When the current operating temperature reaches a final target temperature, an operating current is supplied to the optical source generator, and transmission of the operating current to the optical source generator is controlled and monitored. When the operating current reaches a final operating current, the wavelength tuning of the optical source is terminated. The operating temperature is adjusted by distinguishing between a smaller amount of temperature change and a larger amount of temperature change to prevent oscillation at the point of reaching the final target temperature, thereby minimizing the time taken for the output wavelength tuning.
