A method for video indexing using high resolution still images enables a user to acquire high resolution still images during a video sequence recording so that the user can selectively view the video sequence using the high resolution still images as video indices. The first tibia connecting structure can be inserted into a radial groove on the tibia along a radial direction of the tibia to limit the motion of the tibia component in the axial direction of the tibia. The method includes receiving a parameter stream that includes one or more sets of regional parameters associated with one or more regions. A further improvement is make-before-break timing overlap of the switch operations between the two nulling amplifiers and the main amplifier. The system uses special control software on the called party’s computer which is connected to the Internet. The system includes a plurality of terminals each having an RF4CE communication module, and at least one gateway for storing unique Identifier information and other ID information about a plurality of terminals within a predetermined area in a table and periodically transmitting the table externally.
