Abstract: Implementations of the subject matter described herein provide a solution for extracting spatial-temporal feature representation. In this solution, an input comprising a plurality of images is received at a first layer of a learning network. First features that characterize spatial presentation of the images are extracted from the input in a spatial dimension using a first unit of the first layer. Based on a type of a connection between the first unit and a second unit of the first layer, second features at least characterizing temporal changes across the images are extracted from the first features and/or the input in a temporal dimension using the second unit. A spatial-temporal feature representation of the images is generated partially based on the second features. Through this solution, it is possible to reduce learning network sizes, improve training and use efficiency of learning networks, and obtain accurate spatial-temporal feature representations.

Abstract: To facilitate LWA PDCP setting/scheduling, a method of providing dynamic PDCP status report polling is proposed. To enhance scheduling efficiency, the transmitter (can be eNB from DL or UE for UL) can dynamically poll PDCP status report for LWA behavior. The polling can be done by a standalone PDCP control PDU or use reserved bit in PDCP data PDU. The triggering condition for PDCP status polling includes: PDCP without poll time exceeds a first threshold, PDCP without poll bytes exceeds a second threshold, PDCP without poll PDU numbers exceeds a third threshold, a data buffer is empty, and when LWA is deactivated.

Abstract: A synchronous modulation method based on an embedded player. The method comprises the steps of: Step S1, acquiring a current timestamp adopted by a current synchronous audio signal and a current synchronous video signal; Step S2, acquiring a jump difference value of the current timestamp; Step S3, determining whether the jump difference value is less than a first preset time, if yes, synchronously playing, by the player, the audio signal and the video signal through a first timestamp, and exiting; and Step S4, determining whether the jump difference value is greater than a second preset time, if yes, synchronously playing, by the player, the audio signal and the video signal through a second timestamp, and exiting.

Abstract: A method for signing data such as software images is provided that uses modules executable by a generic client to sign hashes of the software images rather than the images themselves. The method avoids both the requirement for new or updated client software and the uploading of full software images to the signing system. This approach uses a generic client that requests and downloads processing modules from the signing system to perform the pre-processing operations in signing software images, as well as optionally for post-processing operations.

Abstract: Various solutions for handling compression error with respect to user equipment and network apparatus in mobile communications are described. An apparatus may transmit a compressed protocol data unit (PDU) to a network node. The apparatus may receive a negative acknowledgement (NACK) message from the network node. The apparatus may restore a compressed service data unit (SDU) to original data. The apparatus may transmit the original data with an uncompressed format to the network node.

Abstract: Disclosed is a manufacturing process and feature licensing system for provisioning personalized (device-unique) licenses to devices, with the following characteristics. The system is secure in that it uses a secure key wrapping mechanism to deliver the LSK to LPS. Another feature is that various network communication links are secured using standard security protocol. Further, application messages, license templates, licenses are digitally signed. The system is also flexible because it is configured to allow multiple manufacturers and to allow various feature configurations via the use of License Template. The system is also scalable, as it is possible to use multiple LPS hosts to serve multiple programming stations. The system is available in that the delegation of license signing capability from CLS to LPS eliminates the dependency on unreliable Internet connections. Redundant LPS hosts provide high level of availability required for high volume license provisioning.

The password is stored securely in the system, permanently or temporarily, and is used later to decrypt the files right before the system is ready to process the files.

Abstract: A camera device includes a base, an image sensing component and a gravity center adjustment mechanism. The image sensing component is located on the base. The gravity center adjustment mechanism includes a circuit board disposed on the base, an adjusting module and a weight component.
