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.

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 target material removal (TMR) element is provided and includes a body region; thermal elements within the body region; and vibration elements within the body region. The TMR element is controlled to perform TMR operations that include one or more of the thermal elements generating heat that is transmitted through the body region to a target material in a manner that defines one or more zones of the target material. The TMR operations further include, subsequent to the one or more of the thermal elements beginning generating the heat that is transmitted through the body region to the target material, the one or more of the vibration elements generating vibrations that are transmitted through the body region to the one or more zones of the target material.
