Abstract: Disclosure herein is related to a portable voice routing apparatus, a system, and a method for processing a telephony voice call. In an exemplary embodiment of the invention, the portable voice routing apparatus provides a local network protocol service for the local-end terminal devices, and renders a connection bridging a mobile communication network. When the terminal device initiates a telephony voice communication procedure, the portable voice routing apparatus transmits the voice packets carried with subscriber identity information. Therefore the terminal device may establish a voice communication with a recipient over PSTN or network. At the recipient, a message with an incoming call is shown due to the received subscriber identity information. The recipient may therefore call back for bi-directional voice communication according to this message.

Abstract: A method for aiming a pan, tilt, and zoom (PTZ) camera captures a first image of a monitored area, and calculates a state vector of a predetermined object or point in the first image at one zoom setting. The state vector of the predetermined object or point is recorded in a state vector table. The method aims the PTZ camera to align a center point of the first image to a selected target point, and captures a second image of the monitored area. In order to calculate state vectors of points in the second image, N pieces of reference images related to the second image are calculated using a particle filter. After calculating a similarity between each of the N pieces of reference images and the second image, the method calculates the state vectors of the points in the second image according to each similarity, and updates the state vector table with the state vectors.
