A method for stabilizing a load suspended with a rope, cable, net, sling or the like is disclosed. A beacon having a plurality of lights thereon may be attached to the load relative to the attachment point to the load, to an attachment point of the load or to the rope, cable sling or the like. A sensor on the lifting device senses the beacon and thus any swinging motion of the load, and a processor responsive to the sensor develops control signals that direct motion of the lifting device to dampen any swinging motion of the load.

Load tracking and stabilization

A system is disclosed for remotely determining 6 degree of freedom of an object. Four or more radiating beacons are placed on an object, the beacons each simultaneously radiating a synchronized repeating code, the code being different for each beacon. A position sensor, such as a quadrant detector, receives the light signals from the beacons, and correlates the received beacon signals against the same signal sequences produced in the receiver. With orientation of the beacons on the object being known, and orientation of the quadrant detector, or receiver, being known, roll, pitch, yaw, and X, Y and Z position in a coordinate space of the object can be determined.

System and method for remotely determining position and orientation of an object

A method for automatically guiding a lifting device on a lifting apparatus to a lifting point on a load is disclosed. A beacon is associated with the lifting point on the load has a plurality of lights arranged in a predetermined pattern. A sensor on the lifting apparatus detects the lights and provides signals to a processor. The processor calculates location of the lifting point, and develops signals that directs the lifting apparatus, or an operator of the lifting apparatus, to engage the lifting point with a lifter on the lifting apparatus. The load may then be lifted and moved.

Automated system for load acquisition and engagement

A range and bearing-finding system is disclosed. A diverging encoded laser beam is transmitted to a target, and a return reflection of the encoded beam received. The transmitted beam is sampled, and a plurality of predetermined time delays are applied to the sampled laser beam. The sampled laser beam with each of the predetermined time delays is correlated with the return reflection until a sampled laser beam having a time delay providing the highest correlation is found, the time delay indicating laser travel time to and from the target. Range is determined from this time delay. Bearing of the target is found by using a quadrant protector to receive the return reflection. The process for finding bearing uses the correlation process used to find range.
