Abstract: Sensor-based systems and methods of analyzing shaving usage based on time duration. A shaving device comprises a blade. The shaving device is communicatively coupled to a sensor and one or more processor(s). Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define one or more shaving strokes based on pressure applied to the user's skin. Based on the one or more shaving strokes and timer intervals thereof, a total duration can be tracked. The total duration can be determined to meet or exceed a predetermined threshold value. An output associated with the shaving device may be generated based on the determining that the total duration meets or exceeds the predetermined threshold value, the output comprising an indication that the total duration meets or exceeds the predetermined threshold value.

Abstract: Sensor-based systems and methods of analyzing shaving usage based on time duration and shave event status. A shaving device comprises a blade. The shaving device is communicatively coupled to a sensor and one or more processor(s). Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define shaving stroke(s) based on pressure applied to the user's skin. Based on the one or more shaving strokes and timer intervals thereof, a total duration can be tracked. In addition, a shaving event can be determined based on the shaving stroke(s). An output associated with the shaving device may be generated based on the determining that each of a predetermined duration threshold value and a predetermined shave event threshold value has been met or exceeded, the output comprising an indication that the each of the thresholds has been met or exceeded.

Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define one or more shaving strokes based on pressure applied to the user's skin. Based on the one or more shaving strokes, a shaving event can be detected and a shave event count value can be an incremented. The shave event count can be determined to meet or exceed a predetermined threshold value. An output associated with the shaving device may be generated based on the determining that the shave event count value meets or exceeds the predetermined threshold value, the output comprising an indication that the shave event count value meets or exceeds the predetermined threshold value.

Abstract: A system for storing time series data includes an ingester that prepares metadata indices associated with blocks of incoming time series data and stores the blocks of data in a time series database and the indices in a separate index database. The time series database distributes storage of the data blocks among multiple data nodes. A query layer receives queries and uses the index database to determine which data blocks are needed to process the query, and then requests only those data blocks from the time series database. Processing of the query is performed within the time series database only on those data nodes that contain relevant data, and partial results are passed to an output layer for formation into a final query result.

Abstract: A method for performing queries on a distributed time series data storage system is presented. The time series data storage system has a time series database that stores data blocks containing time stamped data across a plurality of computing devices. The system also includes an index database that stores an index associated with the time stamped data in each data block. The method includes the steps of sending a query, requesting indices, returning the indices, preparing a sub-query, forwarding the sub-query to an evaluator, evaluating the sub-query, performing a logical operation on each sub-query's result, receiving the sub-results at an output handler, and combining the sub-results.

Abstract: A service for storing time series data provides a data pipe for receiving time series data, a query pipe for making requests to the service, and a result pipe for receiving output from the service. Data sent to the query pipe is processed by an ingester that prepares metadata indices associated with blocks of incoming time series data and stores the blocks of data in a time series database and the indices in a separate index database. A query layer receives queries from the query pipe and uses the index database to determine which data blocks are needed to process the query, and then requests only those data blocks from the time series database. Processing of the query is performed within the time series database only on those data nodes that contain relevant data, and partial results are passed to an output layer for formation into a final query result which is sent out by the results pipe.
