Abstract: Disclosed herein is a method for skeleton-based action recognition using handcrafted features. The input of the model is keypoint data of one or more skeletons from the frames of a video clip. Several histogram features are used to describe the spatial and temporal patterns of the corresponding body. These features are concatenated and sent to a linear classifier to predict the category of the actions.

Abstract: Disclosed herein are training strategies for query-based object detectors, referred to herein as Query Recollection (QR). In one variation or QR, dense query recollection, every intermediate query is collected and independently forwarded to every downstream stage. In a second variation or QR, selective query recollection, intermediate queries are collected from the two nearest previous stages and forwarded to the next downstream stage. This eliminates the phenomena wherein intermediate stages of the decoder produce more accurate results than later stages of the decoder.

Abstract: A chainsaw includes a chain, a liquid pump assembly, a motor, and a controller. The chain is used for implementing a cutting operation. The liquid pump assembly includes a liquid pump and a motor. The liquid pump is used for releasing a liquid for lubricating or cooling the chain. The motor is used for at least driving the liquid pump to operate. The controller is electrically connected to at least the motor. The controller is configured to, when the liquid pump is in the jammed state, control the liquid pump assembly to enter a throttling mode in which a supplied amount of the liquid is reduced, and when the liquid pump exits the jammed state, control the liquid pump assembly to exit the throttling mode. Technical solutions provided by the present application can determine and release the jammed state of the chainsaw.

Abstract: An electronic device includes a display screen and at least one button. The display screen is a foldable screen. In a process in which a user uses the electronic device, a function that needs to be responded to by a button on the electronic device may be adaptively adjusted based on a physical form of the foldable screen of the electronic device, so that a button function that conforms to a using habit of the user can still be provided when the foldable screen of the electronic device is in a different physical form.

Abstract: A display panel is provided. In the display panel, color resists are disposed in light-emitting regions and correspond to light-emitting pixels, and overlapping color resists are disposed in non-light-emitting regions, so as to replace polarizers. This increases a light transmittance of the display panel, reduces a reflectivity of the display panel, and reduces a thickness of the display panel. Furthermore, because the overlapping color resists are used to replace a black matrix in the non-light-emitting regions, process steps are reduced.

Abstract: One or more characters are input into an auto-complete field. Text of a displayed list of one or more candidate items is retrieved. The text of the displayed list of the one or more candidate items is compared to a predefined candidate item. In response to the text of the displayed list of one or more candidate items not having the predefined candidate item or not being withing a defined ranking, test results are flagged where the predefined candidate item is missing from displayed list of the one or more candidate items or is not withing the defined ranking. This allows the for automated testing of the auto-complete fields.
