Abstract: A communication broker service of a microservices platform may direct a distributed queue management service to monitor multiple data distribution outboxes of a plurality of microservices of the microservices platform for message data. The communication broker service may receive an indication from the distributed queue management service that the distributed queue management service has retrieved message data from a data distribution outbox of a first microservice. The communication broker service may apply a business logic to identify one or more second microservices that are configured to receive the message data from the first microservice. The communication broker server may then direct the distributed queue management service to distribute the message data of the first microservice from a data store of the distributed queue management service to one or more corresponding data distribution inboxes of the one or more second microservices.

Abstract: This disclosure describes techniques that enable a categorization controller to detect activation of a portable recording device that is configured to capture a real-time multimedia stream of the current event. The categorization controller may further identify a set of categories that are likely associated with the real-time multimedia stream, determine an ordered ranking of the set of categories, and generate a ranked category dataset for delivery to the portable recording device. In doing so, the portable recording device may present the ordered ranking of the set of categories at a user interface.

Abstract: A system and method for multi-media content bookmarking with provenance supplements multi-media content captured by media recording devices used or carried by a police officer during the course of his/her duties with information inputted by the police officer, wherein the added information is in the form of metadata. In at least one embodiment, a user interface (UI) tool for inputting the supplemental metadata is the source of provenance for the metadata, and the supplemental metadata is tagged to the captured content in a manner that preserves the provenance of the captured content. In a further embodiment, the user interface further enables the officer to create an affidavit as to the veracity of the supplemental metadata. The supplemental metadata may be stored in conjunction with the captured multi-media content in a secure data storage, but the content itself is not altered, thereby maintaining provenance of the content.

Abstract: This disclosure describes an apparatus and system for classifying audio and video data captured by a portable recording device. The portable recording device may comprise a camera system enclosure that captures audio and video data that reflects a user's point-of-view perception of their surroundings.

Alternatively, or additionally, the video and/or audio data may be stored within memory of the portable recording device. This disclosure further describes a CMM system that may act as a central repository of multimedia data from one or more portable recording device(s). The CMM system may further generate and assign incident report forms for each individual instance of real-time data that is recorded by a portable recording device.

Abstract: Incoming sensor data from a data collection device may be received at the data processing platform that includes the plurality of data processing microservices.

Abstract: Sensor data from one or more protective equipment sensors of protective equipment worn by a person are received. In response to determining based at least on the sensor data that no emergency situation occurred for the person, sensor data is sent from the body-worn hub to a server when a route of communication is available. In response to determining based at least on the sensor data that an emergency situation occurred for the person and at least one route of communication is currently available, the sensor data is sent from the body-worn hub to the server via at least one route of communication. However, in response to determining based at least on the sensor data that an emergency situation occurred for the person and there is no available route of communication, the sensor data is analyzed at the body-worn hub to determine whether the person is injured.

Abstract: A subscriber device may perform a key exchange with a network operation center (NOC) computing device to receive a secret key. A list of group identifiers of personal devices for which the subscriber device is to handle events may be received at the subscriber device. The subscriber device may receive an encrypted event packet from a personal device via a direct communication connection. The subscriber device may decrypt the encrypted event packet at the subscriber device using the secret key to generate a decrypted event packet and extract a group identifier from the decrypted event packet. In response to determining that the group identifier is included in the list of group identifiers received from the NOC computing device, an event handler of a plurality of handlers stored in the subscriber device that corresponds to an event included in the decrypted event packet may be identified to handle the event.

Abstract: This disclosure describes techniques for a consumer application that integrates a model-controller-view (MCV) design pattern with an event streaming platform such as an Apache Kafka™ in a network operation center (NOC) server to support NOC workspace interoperability. The MCV design pattern may include a pattern that divides an application into three main logical components (e.g., model component, controller component, and view component) to handle specific aspects of the application. In one example, the model component decouples the telemetry data streams from an event stream platform, and the controller component filters a queried set of decoupled telemetry data streams to dynamically control views to be rendered in the view component.

Abstract: A data model computing device receives a first data model with a first set of attributes, a first margin of error, a first set of predictions, and an underlying data set. Subsequently, the data model computing device receives a second data model with a second set of attributes, as the test data for a machine learning module. Based on the first and second data model, the machine learning function generates a second set of predictions and a second margin of error. The data model computing device performs a statistical analysis on the first and second set of predictions and the first and second margin of error to determine if the second set of predictions converge with the first set of predictions and second margin of error is narrower than the first margin of error, to determine if the second data model improves the prediction results of the machine learning module.

Abstract: This disclosure describes techniques for capturing still images during video streaming to identify patterns in a region-of-interest on the captured still images. The video streaming may be performed by an imaging device that includes or is communicatively connected to one or more sensors (e.g., radar, light sensor, etc.) The one or more sensors may be configured to perform data measurements such as vehicle speed measurements, light intensity measurements, and/or the like. In one example, during the video streaming, the data measurement may be compared with a corresponding threshold. In this example, the imaging device may be triggered to capture still images of the surrounding area based on the comparison between the data measurement and the corresponding threshold. Thereafter, the still images may be processed to identify the region-of-interest on the still images.

Abstract: This disclosure describes techniques for creating a universal schema with default fields that support sensor formats of different devices. In one example, the universal schema supports substantial equivalents between data fields in different sensor formats. Further, a sensor format may be configured to support inheritance and aggregation of sensor formats in prior devices. Accordingly, the mapping of sensor formats that supports inheritance and aggregation in the universal schema may provide several advantages such as capturing a mapping of substantive equivalents between the fields in different sensor formats.
