摘要:
A method of quickly and accurately associating a customer name and address with a unique RFID identification tag to be used on a waste or recyclable materials container by the customer. A self-adhesive RFID label including an embedded RFID identification tag is provided in an envelope. Using a hand-held RFID tag reader or more preferably, an RFID reader mounted in a printer coupled to a computer device, a customer name and address is selected from a database and printed on an envelope or directly on the RFID label. Using the RFID reader in the printer and while the customer name and address is being printed, the unique RFID identification number from the RFID identification tag is read, provided to the computer device and automatically inserted into the customer database record, thereby associating the unique RFID identification tag number with the customer record. The RFID label is then delivered (mailed) to or picked up by the customer, all without need to send someone to a customer site to read the RFID tag associated with a waste or recycle bin and associated with the customer record. The customer can then easily apply the self-adhesive label with the RFID tag to their appropriate waste or recycle container.

The invention provides a sensor element formed in a first substrate and having a thermal barrier disposed between the sensor element and a heat source provided elsewhere on the first substrate. The thermal barrier includes at least one pair of trenches formed within the first substrate, individual trenches of the pair being separated by a cavity.
