Abstract: The present disclosure provides an annular water curtain combined water-jet guided laser machining device and method of using the same. The annular water curtain combined water-jet guided laser machining device includes a laser-water coupling device, an annular water jet device, a nozzle, and an annular nozzle. The nozzle is arranged at a lower end of the laser-water coupling device. The annular nozzle is arranged on the annular water jet device. The nozzle is coaxially arranged in the annular nozzle. The laser-water coupling device is used for coupling a laser beam with high-pressure water and spraying a laser guiding water jet from the nozzle. The annular water jet device is used for spraying high-pressure water from the annular nozzle to form an annular water curtain surrounding the laser guiding water jet. It is mainly used for precision hot machining such as cutting, punching and grooving.

Abstract: A plastic keypad with data entry elements and at least one display element is protected from electrostatic discharge by an assembly having an overlay substrate on which an electrically-conductive arrangement is disposed. The overlay substrate has a top side and a back side with a precisely-positioned vias formed through the substrate. A top surface of the top side is a layer of a conductive polymer. The back side is printed with at least one layer of color ink that depict a plurality of alpha-numerical and pictorial elements of the keypad. The electrically-conductive arrangement is disposed on the overlay substrate to collect electrostatic charges on the top side, transfer the electrostatic charges to the back side through the plurality of vias and drain the transferred electrostatic charges to a ground.

Abstract: An apparatus and a method for executing a customized production line using an artificial intelligence development platform, a computing device and a computer readable storage medium are provided. The apparatus includes: a production line executor configured to generate a native form of the artificial intelligence development platform based on a file set, the native form to be sent to a client accessing the artificial intelligence development platform so as to present a native interactive page of the artificial intelligence development platform; and a standardized platform interface configured to provide an interaction channel between the production line executor and the artificial intelligence development platform. The production line executor is further configured to generate an intermediate result by executing processing logic defined in the file set and to process the intermediate result by interacting with the artificial intelligence development platform via the standardized platform interface.

Abstract: Disclosed are a method and apparatus for implementing security of broadband bus architecture in industrial internet field. The security of the access process can be guaranteed by encrypting data transmitted between the bus terminal and the bus controller; the operation of the entire system can be prevented from threat of abnormal data by performing security detection on the acquired data; it can be easy to treat abnormal conditions of the transport rule by the bus controller by monitoring and reporting the transport rule of the data flow over the bus by a bus terminal; and the reliability of the transmission process may be improved by interleaving the to-be-sent data at the bus controller and the bus terminal; the time delay of the data transmission resulting from the addition of the interleaving processes can also be reduced to have high transmission rate.

Abstract: A method, device, and system are provided for suggesting application update. In the method, the device obtains version information of a running application installed on the terminal device and reports the version information. The terminal device receives a version prompting message based on the version information and stores the version prompting message. When the running application enters into a suspended state in the terminal device, the device extracts the stored version prompting message and displays the version prompting message informing the terminal device to update the suspended application.
