Abstract

Thermal indication methods and systems. In one example, electrical power is generated based on a temperature of a thermal surface, and at least one indication is provided, based on the generated electrical power, representative of the temperature of the thermal surface.

Claims

1. An indication system for a thermal surface, comprising:

at least one indicator; and

at least one power source coupled to the at least one indicator and the thermal surface, the at least one power source providing electrical power to the at least one indicator based on a temperature of the thermal surface, such that the at least one indicator provides at least one indication representative of the temperature of the thermal surface.

2. A thermal indication method, comprising steps of:

generating electrical power based on a temperature of a thermal surface; and

providing at least one indication, based on the generated electrical power, representative of the temperature of the thermal surface.
