Abstract: A wing unit of an unmanned aerial vehicle includes a middle wing, an outer wing and a connecting device which includes a first connecting portion and a second connecting portion. One of the first connecting portion and the second connecting portion is fixed on the middle wing and the other one is fixed on the outer wing. The first connecting portion and the second connecting portion are detachably connected. The connecting device also includes a restricting device which enables the first connecting portion and the second connecting portion to be fixedly connected or be separated.

Abstract: A fluid coupling mating apparatus and method. Included is at least one mating member for removably coupling with another mating member for allowing fluid to pass therebetween. A lock is movably coupled to the at least one mating member. Still yet, a holder is coupled to the lock for holding the lock in relation to the holder during at least a portion of the removable coupling of the at least one mating member with another mating member.

Abstract: The present disclosure relates to a cold plate and vapor chamber for conduction cooling of one or more printed circuit boards in a printed circuit board (PCB) enclosure. The cold plate may include a planar surface at an oblique angle relative to an axis along which the PCB assembly is inserted into the enclosure. The PCB assembly may include a vapor chamber having a complementary obliquely angled surface. The complementary angled surfaces of the cold plate and vapor chamber may exert forces against each other upon insertion of the printed circuit board assembly into the enclosure and contact between the cold plate and vapor chamber.

Abstract: A heat spreader and a method for making a heat spreader are disclosed. In an embodiment the heat spreader includes an enclosure with a hollow core and a foam core located in the hollow core.
