  • Patent number: 9278832
    Abstract: A method of reducing computational demand for image tracking includes first receiving a plurality of images of a load hoisted with hanging wire in a preset transitional space, setting at least one monitoring point each at the load and the hanging wire, respectively, providing a tracking frame at the outer periphery of each monitoring point, allowing each tracking frame to track on its corresponding monitoring point that each monitoring point is kept on a relative location within each corresponding tracking frame, and producing the same displacement as that of the monitoring point, and lastly computing the displacement of each tracking frame thus obtaining the displacement of each monitoring point in correspondence to the tracking frame to calculate various displacement of the hanging wire and the load, respectively. With this image tracking method, the processing quantity of whole image data is effectively decreased and computational demand of equipments is reduced.

  • Patent number: 6796447
    Abstract: This crane control system with swing control and variable impedance is intended for use with overhead cranes where a line suspended from a moveable hoist suspends a load. It is responsive to operator force applied to the load and uses a control strategy based on estimating the force applied by the operator to the load and, subject to a variable desired load impedance, reacting in response to this estimate. The human pushing force on the load is not measured directly, but is estimated from measurement of the angle of deflection of the line suspending the load and measurement of hoist position.

  • Patent number: 5490293
    Abstract: A method and apparatus for transferring a load (8) carried by a carrier member (12) between two mutually separate transport paths (3a, b). During transfer, the carrier member switches from being suspended by a device (4a) displaceable in the first carrier path (4a) to being suspended by a device (4b) displaceable in the second carrier path (3b). The carrier member (12) when it is suspended by a first connecting device (9a, 11a) from the displaceable device (4a) of the first conveyor path (4a), is connected to the displaceable device (4b) of the second conveyor path (3b) by a second connecting device (9b, 11b). The length of the second connecting device is reduced and the carrier member (12) is displaced thereby so as to be wholly suspended from the displacement device (4b) of the second conveyor path. A drive mechanism lengthens or shortens at least one of the connecting devices in relation to a housing (14) for modifying the distance between the carrier member (12) and the displaceable devices (4a, 4b).
