  "title": "System for the identification and/or location determination of a container handling machine",
  "abstract": "The invention relates to a system capable of determining in which lane a container handling machine is present below a quay crane or the like crane and/or capable of determining the correct location of a container handling machine in its driving direction (y) with respect to a quay crane or the like crane as containers are delivered to the crane or containers are retrieved from the crane by the container handling machine. The crane is fitted with at least one scanning laser distance sensor or the like range finder, and the container handling machines are fitted with one or more reflectors whose height profile is used for the determination of a correct location and/or for the identification of a container handling machine and for the distinction thereof from other container handling machines.",
  "claims": [
    "1. A system capable of determining in which lane a container handling machine is present below a quay crane, gantry crane, or container crane as containers are delivered to the crane or containers are retrieved from the crane by the container handling machine, wherein the crane is fitted with at least one distance and angular position sensor, and the container handling machines are fitted with one or more reflectors whose height variations are measured using said distance and angular position sensor for the determination of a correct location and for the identification of the container handling machine and for the distinction thereof from other container handling machines.",
    "2. A system as set forth in claim 1, wherein the system is capable of serving several container handling machines simultaneously.",
    "3. A system as set forth in claim 1, wherein the container handling machine has more than one reflector, the combination of which is used for recognizing the identity of the container handling machine.",
    "4. A system as set forth in claim 1, wherein at least one reflector is provided with a portion, inclined in terms of its height in a driving direction (y) of the container handling machine, for determining the correct location of the container handling machine.",
    "5. A system as set forth in claim 1, wherein at least one reflector is provided with a plurality of constant height levels, changing in a stepwise manner in a direction (x) perpendicular to a driving direction of the container handling machine.",
    "6. A system as set forth in claim 5, wherein height values measured by the distance and angular position sensor are matched to a plurality of predetermined constant height levels.",
    "7. A system as set forth in claim 6, wherein measurements matched to the plurality of constant height levels are compared to predetermined options of height levels, programmed onto a computer and matching various reflectors.",
    "8. A system as set forth in claim 1 capable of determining the correct location of the container handling machine in its driving direction (y) with respect to the quay crane, gantry crane, or container crane as containers are delivered to the crane or containers are retrieved from the crane by the container handling machine, wherein the height variations of the one or more reflectors are used for the determination of the correct location of the container handling machine.",
    "9. A system capable of determining a correct location of a container handling machine in its driving direction (y) with respect to a quay crane, gantry crane, or container crane as containers are delivered to the crane or containers are retrieved from the crane by the container handling machine, wherein the crane is fitted with at least one distance and angular position sensor, and the container handling machines are fitted with one or more reflectors whose height variations are measured using said distance and angular position sensor for the determination of the correct location of the container handling machine.",
    "10. A system as set forth in claim 9, wherein the system is capable of serving several container handling machines simultaneously.",
    "11. A system as set forth in claim 9, wherein the container handling machine has more than one reflector, the combination of which is used for recognizing the identity of the container handling machine.",
    "12. A system as set forth in claim 9, wherein at least one reflector is provided with a portion, inclined in terms of its height in the driving direction (y), for determining the correct location of the container handling machine.",
    "13. A system as set forth in claim 9, wherein at least one reflector is provided with a plurality of constant height levels, changing in a stepwise manner in a direction (x) perpendicular to the driving direction.",
    "14. A system as set forth in claim 13, wherein height values measured by the distance and angular position sensor are matched to a plurality of predetermined constant height levels.",
    "15. A system as set forth in claim 14, wherein measurements matched to the plurality of constant height levels are compared to predetermined options of height levels, programmed onto a computer and matching various reflectors.",
    "16. A system as set forth in claim 9 capable of determining in which lane the container handling machine is present below the quay crane, gantry crane, or container crane as containers are delivered to the crane or containers are retrieved from the crane by the container handling machine, wherein the height variations of the one or more reflectors are used for the determination of the correct location and for the identification of the container handling machine and for the distinction thereof from other container handling machines."

  "description_excerpt": "The invention relates to a system as set forth in the preamble of the appended claim 1 for the identification of a container handling machine and/or for determining the location of a container handling machine. Both alternatives apply the same new and inventive features as subsequently revealed.\n\nThe operation of a typical container port shall now be explained to the extent necessary for understanding the invention in terms of its operation. Most of the international transports of goods proceed nowadays by way of containers (1). Containers are standard shape transport units, inside which the goods are packed for the duration of a transport. Containers come typically in three different sizes, either 20 feet, 40 feet or 45 feet in length. Containers arrive in and respectively depart from a container port carried either by a container ship (2), container trucks or container trains. A standard shape transport unit makes the handling of cargo considerably faster at various stages of transportation, especially in the process of loading and unloading a container ship, as well as in a transshipment from marine transport to land transport (loading of a container truck) and vice versa. The presently described invention facilitates automation in the handling of containers, particularly in the process of loading and unloading a container ship, the focus of this description hence being on waterfront operations.\n\nThe container ship (2) is loaded and unloaded by using a special quay crane (4, FIG. 1), which transfers containers from the quay area onto a ship or respectively lifts containers from a ship onto the quay area.",
