Abstract: A dynamically dependent blocking system for orthoses or protectors for limiting relative movements of at least two body segments consisting of at least one blocking unit having a blocking element, an extending element and the body attachment structures, and worn on the body. The central element of the blocking unit is the blocking element.

Abstract: A ram air turbine includes a turbine with one or more blades, a strut removably coupled to the turbine and having a gearbox section and a drive section, a cover located at an end of the gearbox section of the strut with a test plug having a static seal, a turbine shaft and a bevel gear located in the gearbox section of the strut and a driveshaft and a pinion gear located in the drive section of the strut, wherein the pinion gear engages with the bevel gear. The turbine shaft may include a dynamic seal that provides sealing between the turbine shaft and the cover. The test plug may be a threaded plug. The cover may also utilize a dynamic seal. The turbine shaft may include a splined internal cavity for use with a ground test motor.

Abstract: A ram air turbine is provided that utilizes a one-piece strut. The strut includes an integral gearbox section and an integral drive section. Within the strut, a turbine shaft and a bevel gear engages a driveshaft and a pinion gear, which transfers rotation from the turbine to a generator. The strut may be machined from a single piece of metal, such as aluminum.

Abstract: A ram air turbine is presented that includes a turbine having a blade and a turbine shaft, a strut removably coupled to the turbine, wherein the strut has a gearbox section and a drive section, a turbine shaft with a bevel gear oriented perpendicularly to the turbine shaft and positioned within the gearbox section of the strut, a driveshaft coupled to the generator and positioned within the drive section of the strut, and a pinion gear that engages with the bevel gear, wherein the pinion gear is secured to the driveshaft by a spanner nut, wherein the pinion gear utilizes a key configured to interact with the keyed joint of the driveshaft. The pinion gear is supported by a pinion bearing that may be press fit onto the pinion gear and by one of the generator bearings.

Abstract: A ram air turbine having a turbine with one or more blades, a strut having a drive section and a generator adapter section, a turbine shaft and bevel gear located within the drive section, a generator positioned within the generator adapter section of the strut and comprising an exciter and permanent magnet generator in the a turbine side, and a driveshaft having a pinion gear that engages with the bevel gear, wherein the driveshaft is removably coupled to the generator. The strut includes a cone positioned between the drive section and the generator adapter section, and the permanent magnet generator and the exciter are positioned inside of the cone of the strut. The generator utilizes a generator cover and a generator bearing, and the bearing engages with the driveshaft and the generator. The permanent magnet generator and the exciter are positioned within the cone of the generator cover.

Abstract: Systems, methods, and associated software for evaluating financial performance of syndication investments (or other advertising or marketing investments) are provided. A financial performance evaluating system, according to one implementation, includes a first analyzing module configured to determine an organization's donor income from donors within a designated market area. The financial performance evaluating system also includes a second analyzing module configured to determine the programming cost to air programs in the designated market area. From these, a processing module is configured to calculate one or more financial metrics based at least on the donor income and programming cost.

Abstract: A stow abort mechanism for a ram air turbine (RAT) with a strut that rotates a turbine with associated blades from a stowed position to a deployment condition comprises a stow abort lock plate with an aperture that rotates with the strut and a stow abort lock pin that engages the aperture in the stow abort lock plate when the blades do not align properly for rotating the strut back into the stowed position.

Abstract: A ram air turbine (RAT) prevents release of its turbine blades due an over-speed condition by detecting an over-speed condition with a turbine hub-mounted centrifugally operated trigger mechanism and rotating the blades to a fixed coarse pitch position with a release mechanism that responds to the trigger mechanism.
