Claims
- 1. A heating assembly, comprising:a pliable cover; a heating element provided within said cover; a safety circuit located externally of said cover for controlling power supplied to said heating element; said circuit comprising at least one sensor for detecting electrical current supplied to said heating element and generating an output signal; and a power cord having a wall plug, and wherein said safety circuit is mounted on said wall plug.
- 2. The assembly of claim 1, wherein said cover comprises a blanket.
- 3. The assembly of claim 1, wherein said sensor comprises a coil.
- 4. The assembly of claim 1, wherein said heating element comprises positive temperature coefficient wire.
- 5. The assembly of claim 1, further comprising an application specific integrated circuit receiving said output signal and producing a control signal.
- 6. The assembly of claim 5, further comprising a controller receiving said control signal.
- 7. The assembly of claim 1, further comprising a controller, and wherein said safety circuit is carried by said controller.
- 8. The assembly of claim 1, wherein said at least one sensor comprises a pair of sensors, which produce a pair of output voltage signals.
- 9. The assembly of claim 8, further comprising an application specific integrated circuit receiving and processing said output voltage signals to produce a control signal.
- 10. The assembly of claim 1, further comprising an application specific integrated circuit receiving said output signal and producing a control signal and a gain resistor connected to said application specific integrated circuit for adapting said application specific integrated circuit to a specific application.
- 11. The assembly of claim 1, further comprising an application specific integrated circuit receiving said output signal and producing a control signal and a voltage divider connected to said application specific integrated circuit for adapting said application specific integrated circuit to a specific application.
- 12. A heating assembly, comprising:a pliable cover; a heating element provided within said cover; a safety circuit located externally of said cover for controlling power supplied to said heating element; and a power cord having a wall plug for supplying power to said heating element, and wherein said safety circuit is disposed on said wall plug.
- 13. The assembly of claim 12, wherein said safety circuit comprises a sensor for generating an output signal.
