  • Combined range-finding, sighting and scanning system and method
    Patent number: 6717654
    Abstract: An optical system is provided which combines range-finding (distance measurement), sighting (target acquisition) and scanning capabilities. This single beam system uses a polarization selector and a retardation plate to take advantage of the polarization properties of light from a transmit source and of light reflected to a receiver. The system further includes scanning optics for moving the optical beam of light in relation to object in order gather information from the object. Methods for using the system are also provided.

  • System and method of associating an object with a world wide web (WWW) site
    Patent number: 6671738
    Abstract: A method and system for associating an object with a web site is provided. An object in space is identified with unique object-identifying coordinates. These coordinates are compared with a database of object-identifying coordinates that correspond to unique web site identifiers and at least one web site identifier corresponding to the object-identifying coordinates is selected. Once the web site identifier is selected, WWW data may be downloaded relating to the object identified by the object-identifying coordinates. This data may be downloaded with minimal or no intervention from a mobile user once the system has identified the object-identifying coordinates of the object.

  • Volume in space locator
    Patent number: 6420994
    Abstract: Methods and apparatus for determining location information corresponding to a volume in space (VIS) that is occupied by a selected target from a remote observation platform through the process of collecting an identification signal from a source at or near the selected target and associating VIS location information data with that signal to identify location information corresponding to the VIS occupied by the target.

  • Optical system and method for measuring distance
    Patent number: 6411370
    Abstract: An optical system for measuring distance and for range-finding is provided. This single beam system uses a polarization selector and a retardation plate to take advantage of the polarization properties of light from a transmit source and of light reflected to a receiver. Another embodiment of the system uses the properties of certain types of transmit sources to further reduce the dimensions of the system. Methods for using the system are also provided.
