Methods, systems, and apparatus for error correction with syndrome computation in a memory device are described. A first syndrome for first encoded data is generated in a memory device. The first syndrome and the first encoded data are transmitted to a controller that is coupled with the memory device. A second syndrome for first and second encoded data is generated. The first encoded data and the second encoded data are interrelated according to an error correction code. The second syndrome is transmitted to the controller without the second encoded data and the controller is to decode the first encoded data based on at least one of the first syndrome, the second syndrome, or a combination thereof.

The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes. In group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 13/15 is interleaved in a unit of a bit group of 360 bits. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence. The present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.

Embodiments provide systems and methods for performing automated browser testing on different native file types by receiving files of different types. A preview version of each file can be generated and rendered in an output file type. Generating the preview version can be performed by a preview application executed by the testing system and rendering the preview version of the first file can be performed by a browser application executed by the testing system. The output file type can be different from the received file type. For example, the received file type can be a native file type of a first application different from the browser and the output file type comprises an HyperText Markup Language (HTML) file type. A test can be executed on the rendered preview version based on one or more assertions on the first file.

A dynamic vision sensor (DVS) or change detection sensor reacts to changes in light intensity and in this way monitors how a scene changes. This disclosure covers both single pixel and array architectures. The DVS may contain one pixel or 2-dimensional or 1-dimensional array of pixels. The change of intensities registered by pixels are compared, and pixel addresses where the change is positive or negative are recorded and processed. Analyzing frames based on just three values for pixels, increase, decrease or unchanged, the proposed DVS can process visual information much faster than traditional computer vision systems, which correlate multi-bit color or gray level pixel values between successive frames.

A vehicle system includes: a reprogramming slave device that is an electronic control unit (hereinafter, referred to as ECU) to be a target of updating an update file of a program stored among a plurality of the ECUs; a reprogramming master device that transmits the update file to the reprogramming slave device in response to a request from a terminal operable by a vehicle user to control updating of the program stored in the reprogramming slave device; and a determination unit that determines traveling propriety of a vehicle when the update file is rewritten in the reprogramming slave device. The vehicle device functions as the reprogramming master device, and includes: an obtaining unit that obtains the traveling propriety determined by the determination unit; and a notification command unit that commands a notification medium to notify information of the traveling propriety obtained by the obtaining unit.

Systems and methods are described for facilitating operation of a plurality of computing devices. Data indicative of enumerated resources of a computing device is collected. The data is collected without dependency on write permissions to a file system of the one computing device. A condition of the computing device is determined based on historical data associated with enumerated resources of other computing devices. The identified condition can be updated as updated historical data becomes available. A communication to the computing device may be sent based on the identified condition.

The present invention has been made in view of the above problems, and an object of the present invention is to, when an abnormality is detected in an electronic control apparatus that controls a plurality of functions, continue an operation without affecting the other function and secure safety of a control target device corresponding to the function in which the abnormality is detected. In the vehicle mounted electronic control apparatus according to the present invention, each of a first computing portion and a second computing portion outputs an operation check signal, and a driver control unit sets a driver corresponding to the computing portion in which an abnormality is indicated by the operation check signal among the first computing portion and the second computing portion, to a degenerated state.

A robot device includes: a sensor configured to generate sensing data related to an action of the robot device; a communication interface configured to communicate with a server; a memory storing instructions; and a processor configured to execute the instructions to: based on the action of the robot device changing, store action data in the memory, the action data including instruction data corresponding to the action, the sensing data related to the action, and map data related to the action, transmit, to the server via the communication interface, the action data stored in the memory, receive, from the server via the communication interface, threshold data corresponding to the action, and based on identifying that the sensing data is outside of a threshold range based on the threshold data received from the server, generate an event.

Techniques for supporting optical and electrical protocols, such as on the ports of a line card in a network device, are provided. A port on a line card supports optical and electrical connections. The PHY monitors a signal to determine if the transmission connection at the port has changed, such as from optical to electrical, or vice versa. If there has been a change, the PHY is directed to reset a port to correspond to the appropriate transmission connection. By resetting the port, the PHY changes the protocol that is utilized with the signals (e.g., NRZI or 3-Level MLT3).
