An optically open stacked type subminiature optical device according to the present invention has an independent aperture stop structure to enable designing of a stable small optical device having an optical open cover structure, thus improving optical performance. Further, the optically open stacked type subminiature optical device of the present invention is configured in that the aperture stop structure is assembled with another structure into a stacked structure to establish a stable assembly together with the cover structure, thereby allowing for ease of assembly and improving productivity.

A sequential decoding method and a decoding apparatus are provided. According to the method, an open stack is adopted for storing a plurality of paths. When the codeword generated by an internal decoder in the decoding apparatus is incorrect, a codeword is generated again by using the paths stored in the open stack. Accordingly, the complexity of decoding is reduced.

The embodiment of the invention provides a virtual machine migration method and device based on Open Stack. The method comprises the following steps: obtaining the first comprehensive utilization ratios of virtual machines according to the CPU utilization ratio, the memory utilization ratio and the magnetic disk utilization ratio of the virtual machines; adding the first virtual machines of which the first comprehensive utilization ratios are greater than the preset first threshold value into a migration queue; when the migration queue is not empty, determining first physical machines corresponding to the second virtual machines which are not added into the queue; obtaining the second comprehensive utilization ratios of the first physical machines according to the CPU utilization ratio, the memory utilization ratio and the magnetic disk utilization ratio of the second virtual machines; taking the virtual machine, with the minimal weight value, in all second physical machines, of which the second comprehensive utilization ratios are not greater than the preset second threshold value, in the first physical machines as the target virtual machine; migrating the first virtual machine positioned at the head of the queue in the migration queue to the target virtual machine. The comprehensive utilization ratio of the CPU utilization ratio, the memory utilization ratio and the magnetic disk utilization ratio is considered as the resource allocation index, so that the physical machines have higher resource utilization ratios.

The invention provides a sequential decoding method and a decoding device. Permeating an open stack, when codeword fault is generated in an inner decoder, a group of new code wards can be generated by using multi-path storing by an open tack, thus decreasing complexity of the decoding.

The invention discloses a method for overlaying, signing and approving hierarchically based on OFD format files, including 1. multiple clients signing and approving the same file online at the same time; Submit; 3. When reading, first obtain the bottom plate of the document and load the approval content of the document, and load the approval information to the specified corresponding page number and designated vector area according to the coordinates of the approval content; 4. The contents of the approval comments are overlapped and crossed; 5. Extract the list of approval personnel, and form a batch compression icon that can be clicked to open near the approval place; 6. When reading by default, according to the rules set in advance by the system, the priority order will be displayed by default. The approval information is hidden; 7. When choosing to read, click the opened stacked batch compression icon, select the approver who needs to read, and the system will automatically display the approval information of the approver at the approval place and at the same time display the original content hide. The invention makes collaborative work more efficient.

The invention discloses an automatic access method of block storage in Open Stack cloud computing platform, which belongs to the field of cloud computing platform. When users request to add a local storage or network storage, the automatic access method of block storage in Open Stack cloud computing platform can automatically use a pre-installed virtual machine which is provided with a virtual machine image, and then according to the store address and parameter input by users, and the pre-installed Open Stack cloud computing environmental message which is needed accessing, the automatic access method can automatically configure storage service, then the storage service will be initiated automatically and the process of storing and accessing will be finished after configuring. The degree of difficulty and complexity of the automatic access method of block storage in Open Stack cloud computing platform is lower, thereby the probability of making configuration error during the process of storing and accessing can be decreased, the operation and maintenance work of the Open Stack cloud computing platform can be reduced and the automatic access method can have a better spreading application value.

The invention relates to a roller cloth guide-unfolding device, in particular to an anti-loose roller cloth guide-unfolding stacking device. The anti-loose roller cloth guide-unfolding stacking devicecomprises an anti-loose cloth guide component, an upper sliding rack component, supporting plates, a lower sliding rack component, a cloth guide-unfolding mechanism, a cloth rolling flattening mechanism and a cloth laying platform component, the anti-loose cloth guide component is connected to the upper end of the cloth guide-unfolding mechanism, two sides of the bottom end of the upper sliding rack component are each fixedly connected with one of the supporting plates, the bottom ends of the two supporting plates are fixedly connected to two sides of the top end of the cloth laying platformcomponent, the lower sliding rack component is fixedly connected to the front side of the bottom end of the upper sliding rack component, the upper end of the front side of the cloth guide-unfolding mechanism is slidably connected to the front end of the upper sliding rack component in a matched manner, and the upper end of the rear side of the cloth guide-unfolding mechanism is slidably connectedto the rear end of the upper sliding rack component in a matched manner. By means of the anti-loose roller cloth guide-unfolding stacking device, cloth guide-unfolding, cloth conveying, cloth stacking and stacked cloth rolling and flattening can be synchronously realized, and the cloth guide-unfolding efficiency can be effectively improved.

In order to facilitate secure and confidential electronic exchanges, systems and methods include establishing an electronic communication session based on participation levels controlled by a stack software object such that each invitee computing device associated with each invitee is prevented from accessing activities in the electronic communication session unless the invitee satisfies first predetermined parameters based on a locked stack participation level; an initiating computing device associated with the initiating user is enabled to access the electronic communication setting at a reserve level while each invitee computing device is prevented from accessing the activities in the electronic communication session unless the invitee satisfies second predetermined parameters based on an unlocked stack participation level; and the initiating computing device and each invitee computing device are enabled to access the activities in the electronic communication session based on an open stack participation level.

The present application discloses a flow monitoring method of an Open Stack tenant network, including: using a callback function to detect the flow in and out status of a first virtual machine; traffic, use the target flow table rule in the integrated bridge to match the first data flow corresponding to the first traffic, and send the copied first data flow to the traffic monitoring platform; when it is detected that the first virtual machine sends When the third virtual machine in the host sends the second traffic, it uses the target flow table rule to match the second data flow corresponding to the second traffic, and sends the copied second data flow to the physical network bridge, so as to utilize the physical network The bridge performs reflective learning on the copied second data flow to obtain the third data flow; when the integrated bridge receives the third data flow, it sends it to the traffic monitoring platform. Apparently, through this method, the traffic interaction between virtual machines can be monitored.
