Abstract: A method and apparatus for managing memory are provided. The method for managing memory includes: while a virtual machine is running, receiving, by a virtual machine memory management module, a memory allocation request sent by a user process in the virtual machine; sending, by the virtual machine memory management module according to the memory allocation request sent by the user process, the memory allocation request to a virtual PCIe device in a virtual machine manager to enable the virtual PCIe device to request memory from a host memory management module; and acquiring, by the virtual machine memory management module via the virtual PCIe device, a memory space allocated by the host memory management module and configuring the memory space to the user process. The method for managing memory can improve the efficiency of memory utilization.

Abstract: The present invention provides compounds represented by Formula I, or pharmaceutically acceptable salts, stereoisomers, solvates, hydrates or combination thereof, The invention also provides pharmaceutical compositions comprising these compounds and methods of using this compounds for treating FXR-mediated or TGR5-mediated diseases or conditions.

Abstract: An intelligent control method for engine initiation, including: determining whether a current driving mode satisfies a predetermined driving mode; when the current driving mode satisfies the predetermined driving mode, acquiring a current remaining capacity of a battery; determining whether the current remaining capacity is greater than a predetermined capacity threshold value; when the current remaining capacity is greater than the predetermined capacity threshold value, not starting an engine, otherwise, acquiring a catalyst temperature and a vehicle operating state; determining, according to the vehicle operating state, whether the catalyst temperature is less than a predetermined temperature threshold value; when the catalyst temperature is not less than the predetermined temperature threshold value, driving the engine to rotate clockwise to start same in a fuel cut-off manner, otherwise, heating a catalyst by a heating plate until the catalyst temperature is not less than the predetermined temperature th

Abstract: A vending machine (100) and a vending method and vending system (1000) therefor, the vending machine (100) comprising a machine body (10), a door body (20), and at least one layer of shelves (30) and a weighing device (40) that are installed inside the machine body (10). The vending method comprises: collecting the weight of products on a shelf before and after vending (S1); calculating the difference of the change between the weight of the products on the shelf before vending and the weight of the products on the shelf after vending (S2); and if the difference of the change is less than a first weight change threshold, issuing an alarm prompt (S3), wherein the first weight change threshold is less than or equal to zero. Using the present invention may promptly determine the misplacement and replacement of the products without relying on an RFID tag.

Abstract: A method for controlling a self-service vending device to be safely opened, a server and a self-service vending system are provided.

Abstract: A self-service vending device and a vending method thereof, and a self-service vending system. The self-service vending device includes: a device body, a door, at least one shelf mounted in the device body, a weighing module, and a main control module. The weighing module comprises a micro-control unit and a weighing unit corresponding to each shelf. The micro-control unit and the weighing unit corresponding to each shelf are connected. The weighing unit is used for acquiring the weight of goods on the corresponding shelf. The main control module is separately connected to the micro-control unit provided on each shelf to obtain the weight information of goods on each shelf after the vending, thereby determining vending information according to the value of change in the weight of the goods on each shelf before and after the vending. Vending information is identified independently of RFID electronic tags, and thus the costs are low, and the present invention is easy to promote.

Abstract: A smart vending apparatus and a control method thereof. The apparatus includes: a cabinet (10) provided with a product shelf (102) used to display items for sale, the items carrying item information tags. A main control system is provided within the cabinet (10) and has a tag scanner (304) and a communication device (306) being respectively connected to a central processor (302) thereof. Upon receiving a door-opening instruction sent by the server after the server authenticates the identity information, the central processor (302) controls the door (20) to switch from a closed state to an open state. After the door (20) switches from the open state to the closed state, the tag scanner (304) scans all item information tags in the cabinet (10) to determine current inventory information.

Abstract: A barcode reading method and a barcode reading device are provided. An image sensor is utilized to capture an image of a barcode via an optical lens, and then a triangulation method and an ideal lens imagining method are collocated to calculate the digital image so as to produce an optimum image distance. A distance between the image sensor and the optical lens is then adjusted in accordance with the optimum image distance, so that the barcode can be immediately and clearly imaged on the image sensor.
