2. US 11,127,988

   Cartridge and battery assembly with aluminum-nitride heater

   Ceramic heater packaging, clamp-to-PCB electrical and thermal contact, board-level heat rise and a replaceable thermal interface.

3. WO 2019/228389

   Heater control method and device

   Mapping electrical input to thermal output; resistance-temperature behavior; protection and session control built on a thermal model.

4. US 11,284,723

   Ventilated seat pad with framed airflow channel and fan module

   Flow through pores, apertures and a long channel; suction vs blow-through; pressure drop and heat removal by forced convection.

5. WO 2020/134767

   Bowl / heating-chamber assembly for convection-assisted heating

   Two-chamber coupling where a heater volume preheats air that then heats the load; transient air and solid temperatures.

6. US 9,867,398

   Ultrasonic atomizing device without a hot coil

   Air and droplet transport through a compact, variable-flow air path; a non-Joule energy path compared against heated-coil systems.
