FOOD WARMING DEVICE AND SYSTEM
First Claim
1. An apparatus for measuring and controlling the temperature of a heat retention object used to warm or to keep warm a food item, comprising:
- a trivet in contact with the heat retention object, the trivet resting on a countertop and acting as an insulator to limit the amount of heat transferring from the heat retention object through the trivet to the countertop; and
a tag associated with the trivet, the tag being capable of communication with a reader associated with a heating control unit located below the countertop, enabling controlled heating of the heat retention object.

Abstract
An apparatus, system and method for warming food by controlled heating of heat retention objects such as cookware items or pellets located on a trivet positioned on a countertop, using heating control units, such as induction heating units, remotely located beneath the countertop. The preferred trivet insulates the countertop against damages, and also includes circuitry enabling the indication or display of its proper positioning on the countertop, and also indicating whether the heating unit is heating the heat retention object.
