Abstract: Examples of video encoding methods and apparatus and video decoding methods and apparatus are described. An example method of processing video data includes determining, for a conversion between a video block of a video and a bitstream of the video, a gradient of a prediction vector at a sub-block level for the video block according to a rule, wherein the rule specifies to use a same gradient value is assigned for all samples within a sub-block of the video block; and performing the conversion based on the determining.

Abstract: To predict client sensitivity to rate changes for commercial deposit products, a machine learning model is trained using (i) first attributes associated with a corresponding first client during a first rate change, (ii) an indication of whether the first rate change was requested by the corresponding first client or by a corresponding first bank, and (iii) an indication of whether the corresponding first client is sensitive to the first rate change. A second set of attributes is obtained which is associated with a second client having a second commercial deposit product. A machine learning engine applies the second set of attributes and an indication of an initiator of a potential second rate change to the machine learning model to predict client sensitivity to the potential second rate change. Then, a recommendation is provided as to whether to change the second rate based on the predicted client sensitivity.

Abstract: A nozzle supply valve is positioned in the nozzle supply passage of a fuel injector, and is constructed to generate a boot shaped rate trace mechanically. The goal of the concept is to restrict the flow area during the first boot step and release the flow area restriction in the second step. During the first stage of injection, the flow to the nozzle only goes through a restricted orifice. When the line pressure is high enough to overcome the valve movement pressure spring preload, the nozzle supply valve moves to an unrestricted position, and the boot shaped rate trace is formed. Since this boot shape rate trace is generated mechanically, it can be combined with fuel injectors having a direct control needle valve in order to get different rate traces including, ramps, squares, pilots, posts and other split injections.

Abstract: A 3D electronic data input device with a key mapping card which changes from the prior 2 dimensions layout to 3 dimensions layout, has input keys and a mouse mounted on different sides of the keyboard. It also has electronic circus and connection devices. The key mapping card plays critical role to help users to find needed keys. There are several different sizes of the said keyboards to accommodate different hand sizes. The keyboard can hold and even be integrated with electronic device such as PDA.
