Abstract: A device may participate in a shared data state in which editing operations performed locally are distributed and synchronized with other devices participating in the shared data state. Data may be maintained in log-structured storage files on each device. Changes made locally may be conditionally appended to log-structured storage and committed or rolled back during synchronization. Sets of related change descriptors may be identified based on inferred user intent. Conflict resolution rules may be applied to sets of related change descriptors. Conflicts may be resolved through application of conflict resolution rules or through a user-involved process.

Abstract translation: 设备可以参与共享数据状态，其中在本地执行的编辑操作与参与共享数据状态的其他设备分布和同步。 数据可以在每个设备上的日志结构存储文件中维护。 本地进行的更改可能有条件地附加到日志结构存储，并在同步期间提交或回退。 可以基于推断的用户意图来识别相关变化描述符的集合。 冲突解决规则可以应用于相关变更描述符的集合。 可以通过应用冲突解决规则或通过用户涉及的过程来解决冲突。

Abstract: A device may participate in a shared data state in which editing operations performed locally are distributed and synchronized with other devices participating in the shared data state. Data may be maintained in log-structured storage files on each device. Changes made locally may be conditionally appended to log-structured storage and committed or rolled back during synchronization. Devices may exchange sets of related change descriptors preceded by associated contextual information. Conflicts may be resolved through application of conflict resolution rules or through a user-involved process. User notification of conflict resolution may be based on user intent inferred from contextual information and associated change descriptors.

Abstract: A device may participate in a shared data state in which editing operations performed locally are distributed and synchronized with other devices participating in the shared data state. Data may be maintained in log-structured storage files on each device. Changes made locally may be represented by change descriptors conditionally appended to the end of a log. The size of the log may be monotonically increasing. Monotonically increasing identifiers may be used to implicitly or explicitly identify change descriptors. Upon conflict resolution, conditionally appended change descriptors may be committed. Non-committed change descriptors may be conditionally reappended to the end of the log for further conflict resolution.

Abstract: An inventory location, such as a shelf, may be used to stow different items. The shelf is divided into a plurality of adjacent lanes, some of which may be grouped into a cluster. Items are placed upon the lanes of the cluster. Each lane includes one or more weight sensors to obtain weight data about a load on the lane. Based on the weight data and physical layout data for the shelf, one or more hypotheses may be determined for describing interactions, such as a pick or place of an item, occurring at the lanes of a cluster. One of the hypotheses may be selected as a solution for describing the interaction and used to maintain inventory quantities of items at the shelf.

Abstract: An inventory location such as a shelf may be used to stow different types of items. The shelf may be equipped with a plurality of lanes arranged parallel to one another. Items may rest upon two or more of the lanes. Each lane includes a weight sensor that provides weight data about a load on the lane. Based on the weight data and item data indicative of individual weights of those items stowed on the shelf, interaction data indicative of an activity such as a pick or place of an item may be determined. The interaction data may specify what item was picked or placed, quantity of that item that was picked or placed, and so forth. Data from other sensors, such as a camera, may be used to determine the interaction data.
