摘要:
A system and method to detect an event associated with a first object relative to a second object and a support is provided. The system can include an antenna at a support to receive the first object, a tag reader in communication with the antenna and a tag located on the second object. In response to detecting a change in impedance of the antenna associated with the presence of the first object, the tag reader communicates a presence signal. In response to detecting the tag within a threshold proximity of the tag reader, the tag reader generates a tag signal. A remoter server is operable to detect an association of the first and second objects based on a comparison a time associated with each of the tag signal and the presence signal, and in response then creates an output indicative of a detected event based on the association for illustration.
