Abstract: The invention relates to a preparation method for a multifunctional modified molybdenum disulfide nano-additive, with step 1: synthesizing a lignocellulose; step 2: synthesizing lignocellulose/MoS2 composite nanoparticles; step 3: synthesizing a lignocellulose/MoS2—Ag nanocomposite to obtain the multifunctional modified molybdenum disulfide nano-additive. The invention provides a preparation method for a multifunctional modified molybdenum disulfide nano-additive, adding which into the cutting fluid will remarkably improve the lubricating property, bactericidal and corrosion resistance performance.

Abstract: A component protection apparatus includes a chamber configured to enclose a component that is to be protected and contain a liquid that surrounds the component. The liquid is configured to reduce an amount of an impact on the chamber that is transferred to the component. The component protection apparatus further includes a temperature control system configured to permit heating and cooling of the liquid.

Abstract: An unmanned aerial vehicle (UAV) includes a power system providing flight power to the UAV and a frame assembly supporting the power system and including a center frame and an arm assembly. The arm assembly includes an arm connected with the center frame, a deformation rod, and a support rod parallel to the arm. Two ends of the deformation rod are rotatably connected with the arm and the support rod, respectively. The support rod is configured to move translationally relative to the arm while remaining parallel to the arm, so as to be selectively in a folded state or an unfolded state. Each of two ends of the deformation rod forms a first or a second preset angle with one of the arm and the support rod when the support rod is in the folded or unfolded state. The second preset angle is smaller than the first preset angle.

Abstract: A patterned sapphire substrate has a first surface and a second surface opposite to each other, in which, the first surface of the substrate is formed by arranging a plurality of interspaced patterns, wherein, the patterns have a top surface, a bottom surface and a plurality of side surfaces and at least one concave region sandwiched between the adjacent side surfaces and the top surface, where, depth and width of the concave region gradually decrease from the top to the bottom of the pattern. The concave region on the pattern surface of the patterned sapphire substrate enlarges light reflection area, thus improving light extraction efficiency of the patterned sapphire substrate.

Abstract: The present invention provides a vehicle comprising a power source such as a primary battery, a secondary battery, and a supercapacitor. The power source includes a plurality of components. At least one of the plurality of components serves as at least a portion of the structural part of the vehicle. The power source is integrated with the structure of the vehicle, and improves the endurance of the vehicle.

Abstract: The present invention provides a container, a transportation system comprising such a container, and a method of using the transportation system. The container includes a battery that provides electricity to a vehicle such as an unmanned aerial vehicle that is carrying and shipping the container. The battery functions as a supplemental power supply to the vehicle and hence improves the endurance of the vehicle, so that heavier cargo can be shipped over longer distance.

Abstract: The present invention provides an optoelectronic module and an imaging apparatus such as an endoscope comprising such module. The optoelectronic module includes a housing and an image sensor. The image sensor's face has a perimeter S, the cross section of the optoelectronic module along the face has a perimeter H, and S<H<1.6S. In an example, illumination components such as a flashing LED and the image sensor are confined within the minimum bounding circle of the sensor's face. The invention exhibits technical advantage in minimizing the size of the insert portion of the endoscopy.

Abstract: Techniques for providing a consolidated view of directory changes across different directory servers. In one set of embodiments, a changelog record can be received from a directory server, where the directory server is associated with a proprietary changelog format, and where the changelog record is formatted according to the proprietary changelog format. The received changelog record can then be translated into a virtualized changelog record that is formatted according to a standard changelog format, and the virtualized changelog record can be sent to a consuming client. In a further set of embodiments, a “changelog cookie” can be generated for a virtualized changelog record prior to sending the record to a client. In various embodiments, the changelog cookie can act as a globally unique identifier—i.e., an identifier that distinguishes the virtualized changelog record from other virtualized changelog records.
