Abstract: The disclosure provides a disinfectant liquid capable of realizing long-lasting and effective disinfection and sterilization, a preparation method therefor and a film layer. The disinfectant liquid comprises: an active chlorine source accounting for 0.05-20 wt % of the total weight of the disinfectant liquid; an active chlorine stabilizer accounting for 0.05-20 wt % of the total weight of the disinfectant liquid; and a pH buffering agent accounting for 0.05-5 wt % of the total weight of the disinfectant liquid, so that the disinfectant liquid has a pH between 5.5 and 9.0. The disinfectant liquid can provide active chlorine at a stable concentration for a long time, or can sustainably release active chlorine for a long time, thereby providing the function of sustainably and effectively killing various viruses, bacteria, molds, fungi and spores for a long time.

Abstract: The present invention relates to a method for implementing a human skeleton tracking system based on depth data, specifically applied to a human skeleton tracking system based on depth data which is composed of a data acquisition unit, a limb segmentation unit, a skeleton point unit, and a tracking display unit. The units are in a relationship of sequential invocation. The limb segmentation unit uses scene depth data obtained after processing by the data acquisition unit to perform limb segmentation. The skeleton point unit uses the result obtained after segmentation by the limb segmentation unit to compute specific positions of respective skeleton points of a limb. The tracking display unit uses the positions of the skeleton points computed by the skeleton point unit to establish a skeleton model of the human body and perform tracking display.

Abstract: The present invention includes means of using a customized coprocessor to replace a main processor to process or interact with a data processing unit in a complex scene and reducing clock frequencies of the main processor and related modules, thereby achieving low power consumption of the three-dimensional measurement chip. The present invention includes: step 1: determining a system structure of a three-dimensional measurement processing chip; step 2: classifying data processing units according to scene requirements; step 3: adding coprocessors on a system bus; step 4: designing a customized coprocessor or small data control unit; step 5: designing a semi-customized coprocessor or small data control unit; step 6: optimizing software codes and reducing a clock frequency; step 7: verifying the chip to confirm that the chip satisfies design requirements. The present invention is applicable to a plurality of integrated circuits or any internetwork system consisting of a plurality of integrated circuits.

Abstract: A method for acquiring a virtual frame number and a virtual slot number at a virtualization platform is provided. The virtualization operating system receives a command for creating a virtual server sent from a virtualization management platform. In response to the command for creating a virtual server, the virtualization operating system creates a virtual server on a board. After creating the virtual server, the virtualization operating system sends a frame number request message carrying an identifier of the virtual server to the virtualization management platform. The virtualization operating system receives a virtual frame number corresponding to the identifier of the virtual server sent from the virtualization management platform. The virtualization operating system obtains a virtual slot number corresponding to the identifier of the virtual server according to the virtual frame number.

Abstract: A video interworking gateway device, a system and method for implementing a video phone call service are provided, which processes the service when a call object changes if the call is not disconnected. The system includes a video interworking gateway device, a broadband resource device and a bearer connection device. The video interworking gateway device negotiates with a calling H.324 entity about parameters, and connects the calling H.324 entity to the broadband resource device on obtaining negotiation parameters of the calling H.324 entity; the video interworking gateway device negotiates with a called H.324 entity about parameters, obtains negotiation parameters of the called H.324 entity, exchanges the negotiation parameters of the calling H.324 entity and those of the called H.324 entity between the calling H.324 entity and the called H.324 entity, and disconnects the connection between the calling H.324 entity and the broadband resource device.

Abstract: A method and system for allocating a media resource and a device for controlling a media resource. The method for allocating a media resource includes: allocating the media resource processing devices for a resource operation request based on the stored ability information of the various media resource processing devices when the resource operation request is received; and updating the stored ability information of the media resource processing device dynamically. The device for controlling a media resource includes: a memory unit adapted to store the ability information of various media resource processing devices; an allocation unit adapted to allocate media resource processing devices for the resource operation request based on the ability information stored in the memory unit; a dynamic update unit adapted to update the ability information of the media resource processing device stored in the memory unit dynamically.

Abstract: A method of allocating media resources includes: receiving a media resource request from a media resource requesting entity; selecting a media resource processing device capable of fulfilling the requirement according to previously acquired media resource capability information of media resource processing devices, to perform the service operation relating a media resource.
