Abstract: According to an embodiment, a method of selecting a Rice parameter for encoding a video bitstream using at least one processor includes obtaining an absolute level corresponding to a current transform block; determining whether transform skip is enabled; generating a lookup variable based on the absolute level and the determination of whether the transform skip is enabled; obtaining the Rice parameter from a lookup table based on the lookup variable; and encoding a residual subblock based on the Rice parameter.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. Processing circuitry decodes prediction information of a block from a coded video bitstream. The prediction information is indicative of a matrix based intra prediction for the block. The processing circuitry determines entries of a vector based on neighboring samples of the block. An entry can be determined based on one or more neighboring samples of the block. The processing circuitry converts the entries into a reduced bit form with a number of bits satisfying a requirement of using a first multiplication tool that processes fewer bits than a second multiplication tool. Then, the processing circuitry multiplies, using the first multiplication tool, the entries of the vector in the reduced bit form with entries of a matrix to calculate a subset of prediction samples of the block, and determines other prediction samples of the block based on the subset.

Abstract: Session management, security scoring, and friction management are provided herein. Sessions may be monitored for commonalities or other attributes or aspects and closed, terminated, or a freeze placed on additional sessions from being initiated. A security score may be provided which is indicative of how secure a user is with respect to one or more ways the user interacts with a resource. One or more suggested actions or score improvement strategies may be suggested to facilitate improvement of a security score for a user. The security score may be used to affect business decisions made by an institution or financial entity.

Abstract: In example implementations, an apparatus includes a serializer, a re-timing buffer coupled to the serializer, and a plurality of segments coupled to the re-timing buffer. The plurality of segments may be used for controlling a timing of an electrical signal. Each one of the plurality of segments may include a segment serializer, a timing control coupled to the segment serializer and a driver coupled to the timing control. In addition, a phase clock may be coupled to the segment serializer and the timing control of each one of the plurality of segments.

Abstract: One or more embodiments of techniques or systems for session management, security scoring, and friction management are provided herein. Sessions may be monitored for commonalties or other attributes or aspects and closed, terminated, or a freeze placed on additional sessions from being initiated. A security score may be provided which is indicative of how secure a user is with respect to one or more ways the user interacts with a resource. One or more suggested actions or score improvement strategies may be suggested to facilitate improvement of a security score for a user. Friction management may be provided by having one or more additional layers of security applied to an account of a user or an entity based on suspicious behavior or other factors.

Abstract: A serial battery charger including a number of serially connected battery charging sections in which the battery charging section is characterized by a first and second parallelly connected branches. The first branch includes terminals for connecting to the battery to be charged and a current blocking device and the second branch includes a by-passing switch which shunts across the terminals of the first branch when activated. The blocking device in the first branch prevents adverse reverse current flow from the battery to the charger when there is no power supply and also functions as a current block to prevent adverse flow of current from the battery into the shunting by-passing switch when the power supply to the charging section is in operation. This invention provides a simple solution to fulfil the conflicting requirements of an intelligent serial battery charger.
