Abstract: A method of forming a direct bearing joint includes coupling a first load-bearing structure to a second load-bearing structure. The second load-bearing structure includes a first structural feature comprising a first arcuate shape. The method also includes coupling a composite skin including a second structural feature comprising a second arcuate shape to the second load-bearing structure. The composite skin is coupled to the second load-bearing structure such that the first and second structural features are mated against each other to facilitate distributing compressive loads from the second load-bearing structure into the composite skin.

Abstract: A physiological detection device includes a main body, a sensor pair, a signal processor, and a calculation module. The sensor pair is disposed in the main body and adapted to detect a detected portion of a human body, so as to obtain a sensing signal. The signal processor is disposed in the main body and receives and processes the sensing signal, so as to output a digital physiological signal. The calculation module receives the digital physiological signal and calculates to obtain first information and second information of a plurality of feature points of the digital physiological signal. The calculation module calculates a ratio of the second information to the first information, so as to obtain a physiological state index. The digital physiological signal includes a plurality of pulse waves generated according to a time sequence.

Abstract: A method of forming a direct bearing joint includes providing a load bearing structure including a first structural feature having an arcuate shape and providing a composite skin including a second structural feature also having an arcuate shape. The method also includes coupling the first structural feature to the second structural feature such that the first and second structural features are mated against each other to facilitate distributing compressive loads induced into the load bearing structure into the composite skin.

Abstract: A fuselage having a longitudinal window belt has a composite outer skin including upper and lower composite skin sections. The skin includes at least one window opening located at the window belt. The upper and lower skin sections are joined together by a longitudinal splice joint located at the window belt.
