Latest Patents

Doremus holds a patent for an electrically heated air data sensing device. This invention utilizes a positive temperature coefficient (PTC) resistance heater assembly in conjunction with an angle of attack vane. The device provides an automatic means for maintaining the temperature of the vane at a level sufficient to de-ice it. The heater assembly is embedded in a recess within the vane and consists of multiple individual PTC resistors. These resistors are connected electrically and mechanically in parallel by flexible electrically conductive perforated strips. This design allows the resistors to move relative to one another under thermal stress while being encapsulated in a thermally conductive, electrically insulative material that is resilient enough to accommodate expansion and contraction during use.
