Abstract: The spray dried plasma by the nature of its characteristics and the process by which it is made allows for a dried plasma with reduced pathogens. It has at least three aspects of pathogen reduction that results in a plasma product with reduced or no pathogens. The first aspect relates to a spray drying disposable and machine that eliminates or minimizes the introduction of pathogens into the spray drying process and is referred to as the anti-contamination process. The second aspect of pathogen reduction relates to the spray drying process and parameters that reduces pathogens that may be present in the donor plasma, and/or inhibit pathogen growth and/or pathogen proliferation introduced by the donor plasma. The third aspect results in reduced pathogens occurring during storage of the dried plasma wherein the manufacturing and storage conditions are such that pathogens are reduced, and/or pathogen growth and/or pathogen proliferation are inhibited.

Abstract: A method for monitoring an oscillatory signal from an oscillating device includes filtering the oscillatory signal to within a desired frequency band to provide a filtered signal and extracting an amplitude from the filtered signal. The method further includes switching control of the oscillating device when the amplitude exceeds a predetermined amplitude requirement for a predetermined duration. An oscillatory signal monitor includes a first controller and a second controller each configured to independently control an oscillating device. An oscillatory signal based on a position of the oscillating device is filtered to a desired frequency band, and an amplitude is extracted from the filtered signal. A switch is provided for switching control of the oscillatory device from the first controller to the second controller when the amplitude exceeds a predetermined amplitude requirement for a predetermined duration.

Abstract: An actuator hardover monitor for a control surface includes an actuator sensor for detecting an actuator position, a command model of an expected position of the actuator based on an input command, and a monitor to determine whether a difference between the actuator position and the expected position exceeds a threshold for a predetermined duration. A method of preventing a hardover event for a control surface includes commanding an actuator valve to a commanded position, determining continuously when the commanded position, or an actuator valve position, or a control-surface position, or a modeled actuator valve position exceeds a predetermined limit to provide an exceedance. The method may further include filtering a signal of the exceedance based on a time constant to provide a filtered exceedance, and switching to a backup control-surface actuator when the filtered exceedance exceeds the predetermined limit for a predetermined duration.

Abstract: Systems and methods of allocating execution loads to execution components are disclosed. The systems and methods select one of the execution components and one of the execution loads based on selection criteria. The systems and methods then determine whether the selected execution load may be allocated to the selected execution component. If the selected execution load may be allocated to the selected execution component, the systems and methods allocate the execution load accordingly. If the selected execution load may not be allocated to the selected execution component, the systems and methods select another one of the execution components and another one of the execution loads for attempted allocation.

Abstract: Embodiments of a method to determine airspeed for aircraft include determining critical air data parameters without the use of pitot-static systems. Airspeed may be determined by iteratively repeating the method until converging on a stable airspeed value that differs from a previous airspeed value by less than a predetermined threshold. Airspeed may be determined by modeling aircraft lift and repeatedly updating dynamic pressure to converge on an airspeed based on the balance between aircraft lift and weight. Airspeed may be determined based on predetermined relationships between a horizontal control surface position and dynamic pressure. A voting logic method validates or invalidates airspeeds from dissimilar sources, including airspeeds determined using the methods described herein and conventional pitot-static systems.

In another embodiment, a system for continuously estimating aircraft weight during flight is provided that includes a pitot-static subsystem, an angle of attack indicator, an accelerometer, a controller configured to provide a weight signal, and a signal filter for filtering the weight signal to determine a stable aircraft weight.
