摘要:
Several types of noise limit the performance of remote sensing systems, e.g., systems that determine the location, color, or shape of remote objects. When noise detected by sensors of the remote sensing systems is known and well estimated, a Kalman filter can converge on an accurate value without noise. However, non-Gaussian noise bursts can cause the Kalman filter to diverge from an accurate value. Current approaches arbitrarily boost noise with fixed additive or multiplicative factors, which slows filter response and often fails to give timely results. Such noise boosts prevent divergence due to badly corrupted measurements. Disclosed embodiments eliminate a subset of noise measurements having the largest errors from a data set of noise measurements and process the remaining data through the Kalman filter. Advantageously, disclosed embodiments enable a Kalman filter to converge on an accurate value without the introduction of noise boost estimates.

Data from an application is analyzed periodically in real-time using a predictive data model to predict potential application failures. Application logs are used to build the predictive data model. The predictive data model includes features created from the application logs which are good predictors of application failures. The predictive data model analyzes and provides anomaly scores for various anomalies for the real-time data collected over a time period. The anomaly scores are compared with a threshold score to predict the probability of occurrences of application failures. If there is a higher probability of occurrence of an incident of application failure, corrective actions to mitigate or reduce the probability of occurrence of the application failure are implemented.

A Data Synchronization and Failover Management (DSFM) system monitors simultaneous execution of non-identical instances of a software application and may label as a particular result of the software application the earliest output corresponding to that result produced by one of the instances. The DSFM may label one of the instances as a primary instance and the other instances as secondary instances and, if the primary instance fails, may re-label one of the secondary instances that computed all of the operations associated with the last result produced prior to the failure of the primary instance, as a new primary instance.

One embodiment of the present invention provides a system for re-entering erroneously entered data fields in a web form. During operation, the system identifies one or more data fields with erroneous inputs in a first web form. Upon submission of the first web form, the system restructures the identified data fields based on association information of a respective identified data field and displays the restructured data fields in a resubmission window distinct from the first web form.

Disclosed is a method for repairing a fault of a terminal which includes: acquiring, by a terminal, an error log according to fault repairing instructions, and extracting identification information of a corresponding application from the error log; when the application is a local application, according to the identification information of the local application and a preset top level domain name corresponding to an after sales server of the local application, determining an IP address of the after sales server corresponding to the local application; sending the error log to the corresponding after sales server according to a preset receiving port and the IP address of the after sales server; determining, by the after sales server, a solution according to the error log, and feeding back the solution to the terminal; and performing, by the terminal, operation of repairing the fault of the terminal according to the solution. Also disclosed is a system for repairing a fault of a terminal. According to the method and system provided in the present disclosure, the error log of the terminal can be acquired quickly and accurately, repairing the fault is achieved, the occurrence of returning to the factory for repairing is suppressed completely, and economic cost and time for repairing the fault is reduced.

A computer includes multiple devices, each providing different functionality to the computer, such as communication functionality, input functionality, output functionality, and so forth. A reset control system of the computer manages resetting of the devices, resetting individual devices as appropriate rather than resetting the entire computer. In response to a malfunction of a particular device, the reset control system selects a set of one or more devices to reset. The devices to reset include the particular device as well as any other devices that will be affected by resetting the particular device (e.g., devices that cannot be powered down or reset separately from the particular device, or devices the operation of which relies on the particular device). The reset control system resets the set of one or more devices, and then adds each reset device back into the computer.

Methods and apparatus related to adaptive control loop protection for fast and robust recovery from low-power states in high speed serial I/O applications are described In some embodiments, a first bit pattern is detected, at a first agent, that indicates a speculative entry by a second agent into a low power consumption state and one or more control loops are frozen. A second bit pattern is detected (after entering the low power consumption state) that indicates exit from the low power consumption state by the second agent and the one or more control loops are unfrozen (e.g., in a specific order). Other embodiments are also claimed and/or disclosed.
