Abstract: A method and device for testing a positioning and speed measuring system main unit. The method includes: obtaining a first simulation signal by simulating an absolute position sensor and a relative position sensor; sending the first simulation signal to a main unit of a to-be-tested positioning and speed measuring system; obtaining a first result calculated by the main unit based on the first simulation signal; obtaining a second result calculated based on the first simulation signal, the second result being a reference result corresponding to the first simulation signal; and determining that the main unit is abnormal if a comparison between the first result and the second result exceeds a first preset range. Therefore, the main unit can still be tested without components including absolute position sensors and relative position sensors, the test process is simple and easy to implement, a test environment can be built without large-scale investment.

Abstract: Systems and methods are provided for dynamically optimizing and configuring various aspects of virtual desktops in virtual desktop infrastructure. Data collectors can be installed on and operate on various components in the virtual desktop infrastructure, such as on the virtual desktops running on the server, on the virtual desktop clients running on user devices, and on the connection server. The data collectors can operate to collect various types of information from corresponding components, such as application usage data and status, device performance, networking environment and speed, application or system crash data, and so on. The collected data can be logged, tracked, and analyzed to perform various actions on the virtual desktop.

Abstract: A system is described for redirecting multimedia in a collaborative session on a virtual desktop. The virtual desktop session can be established, and collaborator virtual desktop clients can be connected in a collaborative session where each collaborator can view the desktop GUI in their respective virtual desktop client. A request can be received to play media in a media player in the virtual desktop. The media stream can be intercepted in the virtual desktop before it is rendered in the media player and conveyed to each collaborator's client over a separate virtual channel established between the virtual desktop and each collaborator. The data stream can then be rendered in a client media player by each collaborator's client.
