Abstract: Example error correction methods and apparatus are described. In one example method, a register controller detects an error existing in a memory, and after detecting an uncorrected error (UCE), obtains a memory address in which the UCE occurs. The register controller reads raw data from a location indicated by the memory address, stores preset first data in the location indicated by the memory address, and reads second data from the location after storing the first data in the location. The register controller compares the first data with the second data to determine a first failure location in the location, determines raw data stored in the first failure location from the raw data in the location, and performs error correction on the raw data stored in the first failure location.

Abstract: Methods, systems and media for context-aware estimation of student attention in online learning are described. An attention monitoring system filters or restricts the time periods in which student attention is monitored or assessed to those time periods in which student attention is important. These time periods of high attention importance may be determined by processing data from the teacher, such as audio data representing the teacher's voice and/or visual presentation data representing slides or other visual material being presented to the students. Various types of presenter data from the teacher and attendee data from the students may be used in assessing the importance of attention and each student's attention during each time period. The presenter may be provided with feedback in various forms showing student attention performance aggregated or segmented according to various criteria.

Abstract: Generating a user timeline for an electronic device (ED) userData is collected that includes: location data; application data; and activity data. Occurrences of predetermined types of observed events are detected based on the collected data. For each detected occurrence a respective observed event record is stored that includes information about a time and type of the observed event. Planned event records, each including information about a time and type of a respective planned event, are stored for planned events that the user is scheduled to participate in, the planned event records. Events are predicted based on the observed event records and the planned event records. Information about observed, planned and predicted events are output on a timeline user interface based on observed event records, planned event records and predicted event records stored for the predicted events, respectively.

Abstract: A gate-controlled diode includes a substrate, a gate stacked on the substrate, a gate insulation layer, a first two-dimensional semiconductor layer, a second two-dimensional semiconductor layer, a source, and a drain disposed separately from the source. The gate is embedded in a surface of the substrate, and the gate insulation layer covers the surface of the substrate in which the gate is disposed. The first two-dimensional semiconductor layer is stacked on the gate insulation layer, a portion of the second two-dimensional semiconductor layer is stacked on the gate insulation layer, another portion is stacked on the first two-dimensional semiconductor layer. The another portion of the second two-dimensional semiconductor layer stacked on the first two-dimensional semiconductor layer forms a heterojunction. An orthographic projection of the heterojunction onto the substrate is in an orthographic projection of the gate onto the substrate.

Abstract: Methods, devices and computer readable media for interacting with a generated timeline user interface on an electronic device (ED) are provided. The method includes receiving, for a user associated with the electronic device, a user input in respect of an event corresponding to an event record stored in a timeline user database associated with the timeline user interface, generating a set of predefined actions for the event, based on the corresponding event record; and performing one or more actions of the set of predefined actions, on the electronic device.

Abstract: A chip module has a plurality of first ports, at least some or all of the first ports are first selection ports, and each first selection port may act as a write port or a read port. The chip module further includes a first control module. The first control module controls, based on a transmit/receive requirement of the chip module, the first selection port to be switched to a read port or a write port, to match the transmit/receive requirement of the chip module. The first selection port may selectively act as a read port or a write port, so that switching can be performed based on an operating state of the chip module, increasing a read/write bandwidth. The first control module controls an operating state of the first selection port, to flexibly adjust a quantity of read ports and a quantity of write ports of the chip module.

Abstract: Methods and devices for generating a slow motion video segment are described. A first set of video frames captures a video view at a first resolution and at a first frame rate. A second set of video frames captures the video view at a second lower resolution, and at a second frame rate that is greater for at least a portion of the second set. At least two high resolution frames are identified in the first set for generating the slow motion video segment. One or more low resolution frames are identified in the second set corresponding to an inter-frame time period between the identified high resolution frames. The slow motion video segment is generated by generating at least one high resolution frame corresponding to the inter-frame time period using interpolation based on the identified high resolution frames and the identified low resolution frames.
