The present invention determines the dimensions and volume of an object by using a novel 3-D camera that measures the distance to every reflective point in its field of view with a single pulse of light. The speaker housing rotates with respect to a rotation axis that extends outwardly from one face of the antenna housing. Replay signals of variable configurations can be obtained by suitably synthesizing data read out from the respective recording layers. Personality data is received at each of the response units. The signal processing unit calculates a current state of an object according to the sensed signals and historical sensed signals and historical states of the object in the storage unit, and determines one of the at least one service providing unit according to the current state to activate service thereof. Methods of modulating angiogenesis by administering an anti-angiogenic ANG-7 nucleic acid are also provided.
