Marked objects optical selection device, has optical transmitter e.g. laser to illuminate defined surface with light beam and send encoded sender address, where optical or acoustic signal is triggered with receipt of desired information
摘要
<p>The system has an optical transmitter (1) e.g. a laser to illuminate a defined surface (2) with light beam and to send an encoded sender address e.g. a telephone number. A transceiver (5) serving for marking of objects selects the address and conveys previously stored information in the address. A device searches the information, where an optical or acoustic signal is triggered with receipt of desired information by a receiving unit.</p>
