Abstract: A data processing system digitally processes data feeds of inhaler device operation. The data feed represents operation of an inhaler device. The system indexes the live data feed with a key value representing the inhaler device for which the live data feed is obtained. For a particular key value indexed in the in-memory data storage, the system queries, a data feed representing physical operation of an inhaler device, segments the live data feed for that particular key value into a plurality of data samples, process at least a portion of the data samples to classify each of the processed data samples; outputs a prompt specifying whether operation of the inhaler device is within a threshold range of operation. Audio data, temperature data, image data, and ranging data can be processed to classify operation of the inhaler device and the order of operations of the inhaler device.

Abstract: This document describes a search retrieval system for automatically indexing data representing audio-visual recordings and for querying, responsive to a search query, that indexed data representing the audio-visual recordings. The search retrieval system defines weights for semantic features of an audio-visual recording and extracts, based on execution of a first set of rules, one or more semantic features. The system determines a weight for each of the one or more semantic features. A search engine searches nodes in the graph of the semantic features to identify one or more logical relationships for the one or more semantic features extracted. The weights for each of the one or more semantic features are adjusted based on the graph. The data is indexed in association with the one or more adjusted weights for the one or more semantic features, respectively.
