Patent ID: 11879771
Assignee: VERSATILE NATURES LTD.
Field: Handling (Mechanical engineering)
Classification: CPC G  B | IPC B  G

Claim 16:
17. The method of claim 15:
further comprising:
estimating a payload size of the object based on the first timeseries of load values;
accessing an altitude, output by an altimeter coupled to the crane hook, during the second time period; and
predicting a line length, carrying the crane hook, based on the altitude;

wherein selecting the load handling specification for the object comprises calculating a pendulum motion amplitude threshold for the object:
proportional to the line length; and
inversely proportional to the payload size of the object;

further comprising calculating a magnitude of lateral oscillation of the object during the second time period based on the second timeseries of motion values; and
wherein activating the object motion alarm comprises activating the object motion alarm in response to the magnitude of lateral oscillation of the object exceeding the pendulum motion amplitude threshold during the second time period.
