Acoustic tags for E-waste tracking
First Claim
Patent Images
1. A system to track an electronic component, the system comprising:
- an acoustic tag affixed to or embedded in the electronic component, wherein the acoustic tag is configured to transmit an acoustic signal through a liquid at a time-continuous spectrum having one or more amplitude peaks at corresponding frequencies, wherein the acoustic signal comprises a unique acoustic code that is configured to provide information regarding the electronic component and a recyclability of the electronic component;
one or more hydrophones, wherein each hydrophone is configured to detect the acoustic signal and transmit the detected acoustic signal over a wireless data network, wherein at least one of the one or more hydrophones is located in or on a floatation device; and
a digital receiver configured to receive the acoustic signal from the wireless data network, decode the acoustic signal, and compare the decoded signal with one or more entries in a database in order to determine a source of the acoustic signal.
