Abstract: A stab-resistant syringe needle with an elastic protective cap and a stab-resistant syringe are provided, which include the elastic protective cap. After the syringe is used to complete injection, the protective cap can be automatically ejected through simple operations to shield a steel needle, so as to achieve a purpose of preventing stab wounds.

Abstract: Disclosed are systems, methods, and computer-readable media for a hybrid cloud structure for machine-learning based object recognition. In one aspect, a system includes one or more video-capable access points; and one or more processors configured to receive image data from the one or more video-capable access points; perform, at a first processor of the one or more processors, a first process to detect one or more objects of interest in the image data; generate vector IDs for one or more objects detected in the image data; perform, at a second processor of the one or more processors, a second process to identify the one or more objects in the vector IDs; and generate at least one offline trail for the one or more objects based on statistics associated with the one or more objects identified.

Abstract: The invention relates to a catalyst for benzene hydroxylation for preparation of phenol and a preparation method thereof, wherein said catalyst uses a mesoporous material as carrier, and the catalyst is prepared by first modifying the surface of the carrier using aminosilane, then immersing with acetylacetonate salt of metal, and finally washing and drying. Advantage of the invention is that a reactive metal is loaded on the silane-modified mesoporous material to form a homogeneous-heterogeneous composite catalyst, wherein, the reactive metal component is present in a reaction system in a homogeneous form, which ensures high catalytic performance of the catalyst component, and it is loaded on the carrier through bridging action of aminosilane, which improves the acting force between the metal component and the carrier, enhances stability of the catalyst, and facilitates separation of the catalyst from the product.

Abstract: A system, method, and computer-readable storage device configured to display a network topology on a display screen of a computing device. The network topology includes a first group of components in an expanded format and a second group of components in a collapsed format. An input is received that is associated with the second group of components, and is arranged to cause the second group of components to be expanded into the expanded format. Finally, the method includes, based on a parameter and the input, automatically collapsing the first group of components from the expanded format into the collapsed format.

Abstract: In one embodiment, a graphical user interface (GUI) is established for an Internet of Things (IoT) integrated developer environment (IDE) with one or more visual developer tools. Real and/or virtual nodes are provided within the IoT IDE having connectivity and functionality, and a plurality are connected as a logical and executable graph for a flow-based programming framework virtualized across one or more IoT layers. The nodes may then be programmed based on respective connectivity and functionality, such that the logical and executable graph has real and/or virtual inputs, real and/or virtual processing functions, and real and/or virtual actions. Upon deploying the node programming to one or more corresponding platform emulators configured to execute the node programming, the logical and executable graph may be simulated by executing the node programming to produce the one or more actions based on the one or more inputs and the one or more processing functions.

Abstract: The invention relates to a solvent-free green ammoximation process based on membrane distribution with a procedure as: adding TS-1 catalyst and ketone into a reactor in advance; setting the stirring speed and reaction temperature; after reaching the set temperature, adding a certain amount of ammonia and hydrogen peroxide into a reaction solution, wherein the hydrogen peroxide is fed in a way of using membrane as a distributor, the ammonia is fed in a continuous or semi-continuous manner; oxime is produced upon the reaction. The advantages of the invention include the mild reaction conditions, high reacting efficiency, simple operation and environmentally-friendly process. And there is no need to add any solvent during the reaction process. During the ammoximation reaction, both the conversion rate of the ketone and the selectivity of the oxime can be over 98.0%.

Abstract: In one embodiment, respective user devices may be registered for one or more particular users at a particular physical space, and each of the one or more particular users may be associated with a respective user profile. The system monitors a location of each of the particular users within the particular physical space based on a corresponding location of the respective user device, such that upon receiving a search query for a particular type of user within the particular physical space, and determining one or more resultant users that correspond to the particular type of user based on the associated respective user profiles, the system can determine a location of the one or more resultant users. As such, the system can display, on a graphical user interface (GUI), the location of the one or more resultant users on a virtualized map of the particular physical space.
