  • Publication number: 20110128131
    Abstract: The present invention relates to a wireless sensor network, and more particularly, to a head node selection method for clustering in a wireless sensor network and a wireless sensor network. The wireless sensor network for determining a head node that includes: a first node; and a second node wirelessly being in communication with the first node, wherein the first node broadcasts a final head node message which is a message indicating that the first node itself is a final head node to the second node if the residual energy of the first node is larger than the residual energy of the neighboring nodes. It is therefore possible to minimize clustering process time.

  • Publication number: 20100302251
    Abstract: The present disclosure relates to a structure of an animation font file and a text displaying method of a handheld terminal. The structure of the animation font file and the text displaying method may realize an animation using limited hardware resources without using images or videos by sequentially displaying plural font images with respect to input text data in accordance with times set for each frame, in which the text data are input by storing font images through a basic mapping table and an extended mapping table, so as to output different font images for each frame with respect to one text data.

  • Patent number: 7504117
    Abstract: Provided is a method for treating depression with a Nelumbinis Semen extract. The Nelumbinis Semen extract is prepared by extracting Nelumbinis Semen with an alcohol or an alcohol solution. The Nelumbinis Semen extract has been demonstrated using animal behavioral, bio-chemical and molecular biological methods to have strong antidepressive activity, as well as inhibiting immune suppression caused by depression, leading to normal immune responses, and reducing side effects of conventional antidepressants, thereby ensuring safety. Thus, the Nelumbinis Semen extract is useful for preparing a composition or health food for treating depression.
