  • Patent number: 10321181
    Abstract: The present invention provides a conditional access method for an intelligent operating system that comprises a trusted execution environment. A digital TV module acquires all channel messages and a control management message. A media play module distributes a DescramblerId and sends the acquired videoPid, audioPid, casId, ecmPid and emmPid and the descrambler message DescramblerId to a conditional access module. The conditional access module selects a registered conditional access application module according to the casId. The conditional access application module acquires corresponding ecm Data and emm Data from the digital TV module, and sends the ecm Data and emm Data to the conditional access module. The conditional access module sends the messages to a trusted application module. The trusted application module performs parse to acquire EK1, EK2 and ECW. The security chip controls a descrambler corresponding to the DescramblerId to perform descrambling according to the acquired messages.

  • Publication number: 20190159668
    Abstract: A new steerable endoscope for minimally invasive surgery is provided. The endoscope system includes: a wireless steerable endoscope (1), an external magnetic controller (2) and an image/video display (3). The wireless steerable endoscope (1) could be inserted through an incision (4-1) on the body skin (4) and be anchored/steered inside the body cavity by the external magnetic controller (2). It is shaftless, wireless, and can be steered inside the body, operating in a remote manner. Compared with existing endoscopes, it neither requires additional incision nor does it occupy trocar or port space. Without the endoscope shaft, the surgical access trauma and incision size can potentially be reduced, avoiding endoscope-instrument fencing. It can be placed remotely from the access incision, providing an improved and wider field of view. It is soft-bodied and compact in structure, therefore safety is high.

  • Publication number: 20190114254
    Abstract: At least one application runs on a hardware platform that includes a plurality of coprocessors, each of which has a respective internal memory space. An intermediate software layer (MVL) is transparent to the application and intercepts calls for coprocessor use. If the data corresponding to an application's call, or separate calls from different entities (including different applications) to the same coprocessor, to the API of a target coprocessor, cannot be stored within the available internal memory space of the target coprocessor, but comprises data subsets that individually can, the MVL intercepts the call response to the application/entities and indicates that the target coprocessor can handle the request. The MVL then transfers the data subsets to the target coprocessor as needed by the corresponding kernel(s) and swaps out each data subset to the internal memory of another coprocessor to make room for subsequently needed data subsets.
