Publication number: 20230152187Abstract: Provided is a fault signal locating and identifying method of industrial equipment based on a microphone array. The method includes the steps of: acquiring sound signals and dividing the acquired signals into a training set, a verifying set and a test set; performing feature extraction on the sound signals in the training set, and extracting a phase spectrogram and an amplitude spectrogram of a spectrogram; sending an output of a feature extraction module, as an input, to a CNN, and in each layer of the CNN, learning a translation invariance in the spectrogram by using a 2D CNN; in between the layers of the CNN, normalizing the output by using a batch normalization, and reducing a dimension by using a maximum pooling layer along a frequency axis; sending an output from the layers of the CNN to layers of RNN; using a linear activation function; and inputting an output of a full connection layer to two parallel full connection layer branches for fault identification and fault location, respectively.Type: ApplicationFiled: July 29, 2021Publication date: May 18, 2023Inventors: Feng LUAN, Xu LI, Ziming ZHANG, Yan WU, Yuejiao HAN, Dianhua ZHANG

Patent number: 10884905Abstract: The life cycle of an application can be shortened by initiating the creation of a mock-up test script before the development of an application is complete. The concurrent creation of the mock-up test script and the application can reduce a time associated with the life cycle of an application. Mock-up test script creation is based on the user interface (UI) specification and a mock-up graphical user interface (GUI) without business logic. Test script creation can include associating a functional specification and a UI specification with a proposed application and creating a mock-up GUI for testing based on the UI specification. Test script creation can include developing an application based on the proposed application that includes a logic based on the functional specification and a GUI based on the UI specification and creating a mock-up test script based on the mock-up GUI and not based on the logic, the functional specification, and the GUI.Type: GrantFiled: February 1, 2013Date of Patent: January 5, 2021Assignee: MICRO FOCUS LLCInventors: Bo Chen, Jin-Feng Luan, Dror Saaroni

Patent number: 10725889Abstract: In one example, a method for testing a multi-threaded application includes running an initial test of the multi-threaded application and collecting thread generation data and determining the thread hierarchy. The thread execution is then modified to produce a modified configuration and a second test is run with the modified configuration. A device for testing of multi-threaded applications is also provided.Type: GrantFiled: August 28, 2013Date of Patent: July 28, 2020Assignee: MICRO FOCUS LLCInventors: Bo Chen, Jin-Feng Luan, Dor Nir

Patent number: 9710366Abstract: A test code is generated based on a test rule relating to testing of executable code. The test code is executed to perform a test of the executable code, where executing the test code causes performance of actions including operation of user-activatable control elements of the executable code. In response to detecting an abnormal behavior of the executable code during the test, instructions of the test code relating to the actions are saved to allow a replay of the test to identify a cause of the abnormal behavior.Type: GrantFiled: January 29, 2013Date of Patent: July 18, 2017Assignee: Hewlett Packard Enterprise Development LPInventors: Jin-Feng Luan, Yi-Qun Ren
