Abstract: The present invention provides a method and an apparatus for identifying optical storage media comprising: means for capturing an image of an identification ring disposed upon an optical media disc; means for unwrapping the ring to form a flat band; means for searching of the flat band to locate a full string of symbols or characters; means for segmenting the string into individual symbols or characters; means for identifying problem symbols or characters associated with the individual symbol or character; and means for checking each individual symbol or character to determine an acceptable symbol or character and comparing the individual symbol or character to both the acceptable symbol or character and the associated problem symbol or character to determine which is a closer match.

Abstract: A configurable directional antenna includes a center antenna element, a plurality of second antenna elements, and a switch matrix. Each second antenna element, together with the center antenna element, defines an antenna sector. A first portion of the second antenna elements is disposed at an inner radius around the center antenna element. A second portion of the second antenna elements is disposed at an outer radius around the first portion antenna elements. Each antenna sector comprises one of the radially inner antenna elements, one of the radially outer antenna elements, and a conductor extending between the one radially inner and the one radially outer antenna element. The switch matrix comprises first electronic switches for selectively grounding selected ones of the second antenna elements, and second electronic switches each for selectively connecting together the second antenna elements of one of the antenna sectors with the associated conductor.

Abstract: A wireless tracking system consists of a wireless target including a wireless communication system for transmitting a data packet over a communication path, and a locating station for determining a position of the target. The data packet transmitted from the target includes an identification code uniquely associated with the target. The locating station includes a configurable directional antenna, a communication interval processing system, a direction processing system, and a position processing system. The communication interval processing system is in communication with the directional antenna and determines the transmission interval of the transmitted data packet over the communication path. The direction processing system determines the transmission angle of the communication path, and is in communication with the directional antenna for controlling the configuration of the directional antenna so as to facilitate the determination of the transmission angle.
