Abstract: A method may determine that an application with access to a media input resource has been launched by a user. A method may in response to determining that the application is launched, initiate a display of a settings user interface including a control for modifying a media input resource setting accessible via the operating system. A method may control transmission of a media output to the application based on the media input resource setting.

Abstract: A method may receive a selection of content. A method may, in response to receiving the selection, providing a prompt based on the selection and context relating to the selection. A method may display the prompt. A method may, in response to receiving a selection of the prompt, generating output by providing the content and the prompt as input to a language model. A method may display the output.

Abstract: The technology provides a computing device having a human presence sensor module. An image sensor of the human presence sensor module captures imagery, and the imagery is not disseminated outside of the human presence sensor module to another part of the computing device. One or more machine learning models, each trained to identify whether one or more persons are present in the imagery, are retrieved from memory within the human presence sensor module. The imagery received from the image sensor is processed using the one or more machine learning models to determine whether one or more persons are present in the imagery. Upon detection that one or more persons are present in the imagery, the human presence sensor module issues a signal to an operating system of the computing device so that the computing device can respond to that presence by performing one or more actions.

Abstract: The present disclosure relates to the technical field of polymer material, and discloses a device and method for online preparation of a modified polylactic acid material with a polylactic acid melt. The device comprises a twin-screw extruder, a first solid modifier hopper, a polylactic acid melt pipeline and a polylactic acid melt feedstock metering pump, wherein the first solid modifier hopper is connected with Zone I of the twin-screw extruder, the polylactic acid melt pipeline is connected with Zone IV of the twin-screw extruder. The method for online preparation of modified polylactic acid material with the device can avoid degradation of the polylactic acid caused by the secondary processing, improve mechanical property of the prepared polylactic acid and reduce production cost.

Abstract: The present invention relates to the technical field of polylactic acid preparation, and discloses polylactic acid polymerization reaction apparatus and system. The polylactic acid polymerization reaction apparatus comprises a polymerization reactor and an agitating assembly arranged in a flow channel of the polymerization reactor, wherein the agitating assembly comprises an electromagnetic winding mechanism and a magnetic induction element, the electromagnetic winding mechanism is arranged along the inner wall of the polymerization reactor around the magnetic induction element, with clearance formed between the electromagnetic winding mechanism and the magnetic induction element, so that the magnetic induction element and the electromagnetic winding mechanism can induce electromagnetic induction, and thereby the magnetic induction element can rotate around its own axis; a threaded groove is formed on the magnetic induction element.
