Final answer:
In warehouses, Automated storage and retrieval systems, Radio frequency identification, and Camera capture technology are the primary technologies used for package identification and sorting.
Step-by-step explanation:
The technologies used to identify and sort packages in warehouses include:
- Automated storage and retrieval systems (ASRS) which use computer-controlled systems for automatically placing and retrieving loads from defined storage locations.
- Radio frequency identification (RFID), a technology that uses electromagnetic fields to automatically identify and track tags attached to objects.
- Ultrasound technology is not commonly used for package sorting in warehouses.
- Camera capture technology, also known as machine vision, which employs cameras and computers to capture and analyze images for a variety of applications including package sorting.
Among the technologies listed, Automated storage and retrieval systems, Radio frequency identification, and Camera capture technology are commonly used in warehouse operations.
