Abstract: A restructurable hybrid-wing VTOL aircraft includes a fuselage, two wings, two canard wings and a cabin door. The two wings are provided to opposite sides of the fuselage. Each the wing is provided vertically and symmetrically by two rotary wing modules, and thus an H configuration to the fuselage can be formed. While the lower rotary wing module rotates to align the corresponding wing, a change of relative position with respect to the upper rotary wing module can be generated. Through the rotation of the lower rotary wing module, the vertical surface thereof would be transformed into a lift surface for enlarging the aspect ratio of the wing to improve the corresponding lift-drag ratio. Thereupon, a disadvantage of hyper flight-directional stability to the H-configured tail seat-type aircraft caused by the vertical area of the aircraft can be reduced, and so the tail-seat type aircraft can slide to emergency land.

Abstract: An ultrasound patch may conform to a curved surface of a large, curvilinear part of a human body, and may capture ultrasound images of underlying tissue for detection of disease. The patch may comprise a flexible, elastomeric substrate, in which phased arrays of piezoelectric ultrasound transducers are embedded. The phased arrays may steer ultrasound beams through a wide angle to image a large volume of tissue. Mechanical deformation of the flexible substrate as it conforms to a curvilinear body part may change the relative 3D positions of the phase arrays. However, localization may be performed to detect these 3D positions. Data captured by the phased arrays may be processed, to create an ultrasound image of the underlying tissue. A semi-flexible, intermediate layer may partially encapsulate each phased array, to distribute stress at an interface between the rigid phased array and more flexible substrate.
