Abstract: A method for carrying out data integrity protection on a communication network. According to an implementation, a wireless communication device indicates, to a wireless network, the maximum data rate up to which integrity protection is supported for user plane data. A network node (e.g., a node of the core network, such as an SMF) receives this information and determines whether or not to enable integrity protection for user plane data based on the information (possibly in conjunction with other information such as the minimum data rate to be supported, etc.). The network node then communicates the decision to enable or disable integrity protection to a RAN node (e.g., a wireless base station).

Abstract: Techniques are described to adjust transmission rates. For example, in a dual-connectivity system, a first communication node can be in communication with a first network node and a second network node. The first communication node may receive from a first network node a first message that includes a recommended bit rate for an ongoing communication between the first communication node and a second communication node. In some embodiments, the first communication node can, in response to receiving the first message, send an acknowledgment or a non-acknowledgment indicator to the first network node indicating that the first communication node accepts or rejects the recommended bit rate.

Abstract: In this invention, an imaging module and a method for fabricating it are provided. By designing first and second electrodes, a movable part of the second electrode is connected to the flexible part. Upon a voltage being applied to the first and second electrodes, the second electrode moves toward the first electrode, resulting in a stretch and hence a shape change of a flexible part. As a result, the imaging module undergoes a change in terms of focal length, amount of admitted light and/or admissible range of angle of incident light. In particular, a motion controller incorporating the first and second electrodes can be easily fabricated by semiconductor processes to a very small size, making the imaging module very suitable for use in electronic terminals such as mobile phones with confined enclosure spaces.

The diffracted light is diffracted by the output diffractive optical element and is projected out of the waveguide substrate toward the user eye. The transmitted light is continuously transmitted and reflected within the waveguide substrate by the total internal reflection until the transmitted light is totally diffracted out of the waveguide substrate, so as to complete an exit pupil expansion.

Abstract: A layered-keyframe-based, presentation recording service provides for presentation recording sessions, the recording of presentations, and the creation of presentation videos. A user records with the user's device the document pages and page annotations, as well audio and video streams, that are presented using the device during the course of a presentation recording session. The pages, annotations and video streams are efficiently and separately recorded as keyframes. These keyframes are used as document, annotation and video layers to create layered keyframes. A presentation video is created from the layered keyframes and the recorded audio stream. Users can then playback presentation videos at a time, place and manner that is available to, accessible by and/or convenient to them.
