An improved surgical apparatus actuator includes a nail bin assembly (1002), a nail anvil assembly (1001) connecting with the nail bin assembly (1002), and a drive assembly (1003) controlling the nail bin assembly (1002) and the nail anvil assembly (1001) to convert between opening and closing conditions. The nail anvil assembly (1001) includes a nail anvil plate (103) and a nail anvil seat (102), wherein the nail anvil plate (103) is provided on an inner side (1022) of the nail anvil seat (102), the nail anvil seat (102) has the structure, material and processing technology capable of providing high anti-bending performance, the nail anvil plate (103) is cold-punched from a thinner stainless steel sheet. Therefore, the processing difficulty of the components is reduced, and meanwhile, the ability of the actuator chuck to resist bending deformation is improved.

In a secure cloud for transmitting packets of digital data, the packets may be repeatedly scrambled (i.e., their data segments reordered) and then unscrambled, split and then mixed, and / or encrypted and then decrypted as they pass through media nodes in the cloud. The methods used to scramble, split, mix and encrypt the packets may be varied in accordance with a state such as time, thereby making the task of a hacker virtually impossible inasmuch as he or she may be viewing only a fragment of a packet and the methods used to disguise the data are constantly changing.

A method for transferring a digital payment order from a first terminal device to a second terminal device, and for saving the payment order on a payment order server. A payment order request is sent from the first terminal device to the payment order server and, in response, the requested payment order is sent from the payment order server to the first terminal device. The payment order is thereafter transmitted from the first terminal device to the second terminal device, and the payment order is then transferred from the second terminal device to the payment order server to be honored. A message confirming the honoring of the payment order is sent to the second terminal device.

The invention provides a flexible display device and a production method thereof. The production method of the flexible display device includes: firstly, binding the bending area of a flexible displaypanel to a flexible circuit board; secondly, bending the bending area of the flexible display panel to the reverse of the flexible display panel; then making a first protective rubber layer on the front of the flexible display panel corresponding to the setting of the bending area. Compared with the prior art, the flexible display device and the production method thereof have the advantages thatrouting in the bending area is protected by the aid of the first protective rubber layer, difficulty in bending the bending area of the flexible display panel is lowered after the first protective rubber layer is bent on the bending area, the stress on the bending area of the flexible display panel is reduced in bending, and product quality is improved.

A method of determining a component of a medium comprises illuminating the medium to excite a marker associated with the component. Detected photoluminescent emission from the marker in response to the excitation is compared with one or more emission profiles. The component is identified based on a match between the detected photoluminescent emission and at least one of the emission profiles.

A temporary biocompatible stent and method for visceral anastomosis. The stent is provided with integral means for maintaining the structural stability of the stent while providing substantial flexibility. The method comprises fitting the luminal stumps of the viscus over either end of a stent of the invention, and joining the ends of each stump together. A short time after completion of the anastomosis, the stent dissolves and is absorbed safely into the body. The stent and method can be beneficially used in laparoscopic or more invasive traditional surgical procedures. The stent and method are particularly well suited for anastomosis of the bowel.

A method is disclosed for creating a 2D barcode. In an embodiment, the method includes: embedding primary information that can be read by a 2D-barcode-reader in a primary information pattern, and embedding secondary information that is made difficult to reproduce without alteration in a visible pattern. In an embodiment, the visible pattern is embedded within the barcode in at least one area that does not contain any primary information

The invention discloses a storage battery state of charge estimation method based on self-adaptive unscented Kalman filtering. The method comprises that: performance of a storage battery is tested via an HPPC test so that HPPC test data of the storage battery are acquired; parameter identification is performed on the basis of the acquired HPPC test data of the storage battery so that storage battery model parameters are acquired; and an SOC of the storage battery is estimated on the basis of the acquired storage battery model parameters via an AUKF algorithm. According to the storage battery state of charge estimation method based on the self-adaptive unscented Kalman filtering, defects in the prior art that manual amount of labor is large, real-time performance is poor, operation difficulty is high, test and calculation accuracy is low, etc. can be overcome so that advantages of being small in manual amount of labor, great in real-time performance, low in operation difficulty and high in test and calculation accuracy can be realized.

The invention discloses a three-dimensional object detection method based on a view cone point cloud. The RGB image and the point cloud image are collected and annotated, the annotated RGB image dataset and the point cloud image data set are obtained, and the data set is used as a training sample and a test sample. It mainly consists of three networks: cone point cloud extraction network based ontwo-dimensional object detection, three-dimensional object segmentation network based on Point net and three-dimensional bounding box regression network based on offset residuals. The three networksare trained in turn, and the training output of the previous network is used as the input of the next network. The super parameters of each neural network model are set, and the three-dimensional object detection network model is trained by Tensorflow. When the cost loss function is reduced to the ideal degree and the training reaches the required maximum iteration number, the training model is generated. The point cloud image data set is inputted into the trained model, and the 3D object detection result is output. The method of the invention is more perfect and more difficult than the existing three-dimensional object detection method.

The invention discloses a high-purity fishy smell and foreign odor-free fish collagen protein peptide and a preparation method thereof. The preparation method comprises the following steps: cleaning fish skins, and then cutting into blocks and mincing; performing stirring treatment with NaCl solution; centrifugally degreasing to remove paraprotein; adding water to regulate the pH value of initial slurry to be 8.0-8.5; performing combined gradient enzymolysis on alkali protease and neutral protease; deactivating enzyme after the enzymolysis is ended; performing adsorption bleaching by activated carbon; and then performing rough filtration, fine filtration, evaporation concentration and spray drying to prepare the high-purity fishy smell and foreign odor-free fish collagen protein peptide. The high-purity fishy smell and foreign odor-free fish collagen protein peptide disclosed by the invention has a simple process and is easy to industrial production; fishy smell, foreign odor and non-collagen proteins are fully removed in production; the low-temperature biological enzymolysis technology is adopted, and other substances are not added, thereby, the product quality is improved; an obtained fish collagen protein peptide powder has the characteristics the content of amino acid hydroxyproline is not less than 9 percent, and the average molecular weight is lower than 1000Dal; no fishy smell or foreign odor cannot generated, and obvious fishy smell or foreign odor also cannot be generated through heating treatment under the acid conditions. The high-purity fishy smell and foreign odor-free fish collagen protein peptide can be widely applied to processing of various foods and cosmetics as a green functional ingredient.
