Abstract: A positive temperature coefficient (PTC) heater apparatus is provided and includes a PTC heater and a health monitoring unit. The PTC heater includes resistive elements arranged in balanced groups of a bridge formation. Each of the balanced groups is arranged in a corresponding one of the arms of the bridge formation. The health monitoring unit is electrically connected to the resistive elements. The health monitoring unit is configured to determine a fault condition of the PTC heater based on a fractional change of resistance of the bridge formation caused by a failure of any one or more of the resistive elements in any of the balanced groups of the arms of the bridge formation.

Abstract: A protection system including a removal element having shape-memory characteristics. The shape-memory characteristics have been configured to define a first shape of the removal element and a second shape of the removal element. When the removal element is in the first shape, the removal element is in a first position with respect to a to-be-protected (TBP) region of a structure. When the removal element is in the second shape, the removal element is in a second position with respect to the TBP region of the structure. The removal element is responsive to an activation that prompts the removal element to, under influence of the shape-memory characteristics, take on the second shape.

Abstract: A positive temperature coefficient (PTC) heater apparatus is provided. The PTC heater apparatus includes a PTC heater, a resistance temperature detector (RTD) sensor mounted to the PTC heater and a controller logic unit electrically connected to the RTD sensor to receive readings of the RTD sensor, which, when the PTC heater is powered on, indicate whether the PTC heater is faulty.
