Abstract:

A device for recovery of physical objects includes a chain having two ends and a retriever attached to one of the ends. The retriever is configured to locate the object to be recovered and to grasp and retrieve that object once located. The retriever includes transducers that detect acoustic frequencies propagating in a fluid medium. Independent transponders, which can be deployed from the retriever are provided for deployment in an area to be searched. Each transponder emits a predetermined acoustic frequency that is detectable by the transducers. The transducers signal movement of the recovery device for retrieval of the object.
