Abstract: A network system coordinates users who provide geographical location-based services to users. Users can provide textual feedback regarding the services provided by other users. To create a safe user experience and encourage users to continue using the services, the network system determines safety risks of the users by analyzing the textual feedback from users along with metadata associated with the textual feedback. For example, the network system determines a safety score for a user based on classifying textual feedback according to different types of safety risk related to topics such as vehicle operation or interpersonal behavior. The network system can train classifiers using feature vectors derived from textual feedback previously received from users of the network system, which may be labeled in a supervised training process. The network system may provide interventions to high-risk users to help mitigate their safety risk and prevent safety incidents from occurring.

The level shift circuit includes a first current mirror module, a second current mirror module, and a latch module. The first current mirror module and the second current mirror module respectively output a first control logic signal having a phase performance following the first input logic signal and a second control logic signal having a phase performance following the second input logic signal. The latch module is coupled to the first current mirror module and the second current mirror module. The latch module receives the first control logic signal and the second control logic signal, and updates correspondingly and stores the output logic signal and the complementary output logic signal.

Abstract: Described herein are techniques and systems for controlling a broadcast mode and a timer mode to update data stored in respective caches of multiple cache servers. When a cache server is operating in the broadcast mode, the cache server receives a data update or a notification of a data update from a broadcast server. When a cache server is operating in the timer mode, the cache server updates its cache without the use of, or reliance upon, the broadcast server. A cache server is configured to operate in the broadcast mode based on a determination that the broadcast server is capable of broadcasting (e.g., sending) messages and/or data updates to the cache servers. In contrast, a cache server is configured to operate in the timer mode based on a determination that the broadcast server is incapable of broadcasting messages and/or data updates to the cache servers.

Abstract: Described herein are techniques and systems for providing an interactive user interface that presents a set of recommended resolution paths and resolution actions to resolve a user issue. The recommended resolution paths and resolution actions presented can be selected from a database of resolution paths and resolution actions previously employed by technicians to resolve user issues. The database of resolution paths can be accessible by computing devices associated with the technicians, and can store the different resolution paths and resolution actions employed by each of the technicians. Once the user issue has been resolved, the system can determine that the current resolution path has successfully resolved the issue, and update the database to include the current resolution path and/or change the scores associated with the current resolution path.
