Abstract: A safe, quiet, easy to control, efficient, and compact aircraft configuration is enabled through the combination of multiple vertical lift rotors, tandem wings, and forward thrust propellers. The vertical lift rotors, in combination with a front and rear wing, permits a balancing of the center of lift with the center of gravity for both vertical and horizontal flight. This wing and multiple rotor system has the ability to tolerate a relatively large variation of the payload weight for hover, transition, or cruise flight while also providing vertical thrust redundancy. The propulsion system uses multiple lift rotors and forward thrust propellers of a small enough size to be shielded from potential blade strike and provide increased perceived and real safety to the passengers. Using multiple independent rotors provides redundancy and the elimination of single point failure modes that can make the vehicle non-operable in flight.

Abstract: A computer-implemented method for characterizing circulatory blood volume is disclosed. The method has the steps of acquiring a biological signal that emulates the arterial pulse wave from a sensor. Two derived parameters, circulatory stress, which reflects a harmonic of heart rate, and circulatory blood flow, which reflects the amplitude of the unprocessed biological signal, are extrapolated from the biological signal, and are each compared to a threshold value and assessed to determine an adequacy of circulatory blood volume. In embodiments, the assessment of circulatory blood volume is used to manage a patient's cardiovascular autoregulatory function or the adequacy of transfer of fluids to and from the circulatory system, with the ultimate goal of achieving a circulatory blood volume that adequately supplies the demands of the patient's tissues and organs.
