Abstract: An ice protection system is configured for a rotor blade having a leading edge along at least a portion of a spanwise length extending between a root portion and a tip portion. The system has an electric spanwise anti-ice heater configured for placement on the leading edge of the blade and a first electric spanwise de-ice heater adjacent the anti-ice heater and having varying chordwise dimensions. The de-ice heater is configured for placement on an upper surface of the blade or a lower surface of the blade. Electrical connectors for each heater are configured for connection near the root portion of the blade to a source of electrical power.

Abstract: An apparatus and method for properly positioning a patient to allow rapid and effective endotracheal intubation during an anesthetic induction is disclosed. The apparatus includes a plurality of inflatable sections for supporting the patient's head and upper back, where the inflatable sections are independently inflatable and deflatable with respect to one another so that the patient's ear and sternum can be aligned in the same horizontal plane. The apparatus also includes an anchoring means that is attached to at least one of the plurality of inflatable sections for anchoring the apparatus in place. An air system connected to the plurality of inflatable sections and including separate connections to the individual inflatable sections operates to provide air to the apparatus. The apparatus optionally includes an independently inflatable cylinder in the anchoring means that is used in pregnant patients.
