    Abstract: A container tracking system comprises a dispatcher workstation with a graphical user interface and a database. These are used to track the whereabouts of shipping containers in a storage and transfer yard. A mobile unit in the yard is attached to container handling equipment and monitors the container lock-on mechanism. When a container is locked on for a move, the mobile unit starts reporting positions and velocities to the dispatcher workstation over a radio channel. These positions and solutions are computed from a combination of GPS satellite navigation receiver solutions, inertial navigation, and local beacon markers. Reports stop when the container handling equipment unlocks from the container. The database then updates the new position for that container, and the graphical user interface can be used to “see” the container on a yard map.

    Abstract: A system for conveyance and processing of large numbers of identical or at least similar objects (piece goods) has a large number of holders (22) which are movable in sequence along a conveying path (F) which is closed on itself. The holders convey held objects along the conveying path. In stations (30, 31) along the path, actions directed to objects or holders (22) are triggered. For controlling these actions, a selected number of the holders are equipped as signaling holders (23) such that between each two successive signaling holders (23), there is a different number of non-signaling holders. The stations (30, 31) have sensor means (33) for detecting signaling holders (23) as well as a counter (35/41) and a memory (36) for storing the counter reading. In response to a signal (S) generated on detection of a signaling holder (23), the memory contents are overwritten with the current counter reading and the counter is reset to zero.

  • Patent number: 6119052
    Abstract: A market based controller controls the motion of an object on a transport assembly. The transport assembly is formed using sensors and actuators that are proximately coupled in physical space. To efficiently allocate a fixed amount of air pressure directed to the actuators, the market controller maps each market agent to points in space on the transport assembly, as well as, points in time relative to a system clock. Using information gathered from the sensor units, each market agent determines whether to bid on the fixed amount of air pressure each bid interval. Using the bids submitted by the market agents, a market equilibrium price and quantity are computed by a market auctioneer. The air pressure purchased by each market agent is then distributed to the actuators mapped thereto.
