Abstract: The disclosure provides a gate driving circuit, an array substrate and a method for recovering the same. The gate driving circuit comprises: a plurality of cascaded shift registers; a recovering signal line and a first reference signal line, extending along an arrangement direction of the shift registers; and a plurality of recovering units, corresponding to the shift registers respectively. After determining a failed shift register in the gate driving circuit, the recovering unit replaces a signal outputted from the failed shift register with a first reference signal from the first reference signal line and loads the first reference signal to the corresponding gate line for recovering. Thus, compared with a structure of outputting the signal provided by the recovering signal line to the gate line, the gate driving circuit of the disclosure has a less significant attenuation on the signal outputted to the gate line.

Abstract: In one embodiment, a method generates actions for entities found on a video delivery system based on information for user behavior of a user on the video delivery system and generates probabilities for the actions for the entities based on the actions for the entities and the user behavior. A probability for an action indicates the probability the user would select that action for an entity when compared against other actions in the set of actions for the set of entities. The method then selects an action feed based on the probabilities for the set of actions. The action feed includes at least a portion of the actions for the entities. The action feed is outputted to the client for display on an interface where an action on an entity in the action feed is performed by the video delivery system when selected by the user on the interface.

Abstract: A method for designing off-axial optical system with freeform surfaces is provided. An initial system is established. A freeform surface of the off-axial optical system that needs to be solved is defined as a freeform surface. A number of feature rays are selected. A number of intersections of the feature rays with the freeform surface are calculated point by point based on a given object-image relationship and a vector form of Snell's law. A number of first feature data points are obtained from the intersections and surface fitted to obtain the freeform surface.

The before-iteration off-axial optical system is used as the initial system for multiple iterations to obtain an after-iteration off-axial optical system.
