Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to efficiently integrate and manage telemetry data from heterogeneous sensor formats used in law enforcement devices, leading to inefficiencies in data processing and storage.
Innovation Solution
A universal schema with default fields is created to support various sensor formats, utilizing a network operation center (NOC) server to configure new devices, map substantial equivalents, and transform telemetry data to conform with a defined schema, enabling inheritance and aggregation of fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal schema is implemented to support heterogeneous sensor formats, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a universal schema as an intermediary layer between heterogeneous sensor devices and the data processing system. This schema acts as a standardized interface that translates diverse sensor formats into a common structure, enabling adaptability without directly modifying each device's complexity. The schema includes default fields and inheritance mechanisms that mediate between varying device capabilities and unified data handling requirements.
Solution Approach 2:
The universal schema is segmented into hierarchical levels with default fields at the base and device-specific extensions building upon them. This segmentation allows the system to handle heterogeneous sensors by processing only the relevant portions of the schema for each device type, reducing the effective complexity managed at any given level while maintaining overall adaptability.
2Loss of information
If telemetry data from diverse devices is integrated into a standardized format, then loss of information is reduced, but processing time increases
Solution Approach 1:
The universal schema performs preliminary action by pre-defining a standardized data structure with default fields before actual telemetry data arrives. This preparation allows incoming data from diverse devices to be quickly mapped and transformed into the predetermined format, reducing processing time while ensuring complete information capture through the comprehensive schema design.
Solution Approach 2:
The schema creates a standardized copy or representation of heterogeneous sensor data in a unified format. Rather than processing each device's native format directly, the system creates copies conforming to the universal schema, preserving all essential information while enabling efficient standardized processing of the copied data structures.
3Ease of manufacture
If a hierarchical schema with inheritance is implemented, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The hierarchical schema implements universality through inheritance, where a parent schema defines common fields applicable to multiple device types. This universal base schema can serve multiple device formats, simplifying the manufacturing and deployment process. Child schemas inherit from this universal parent, automatically gaining the common structure while adding only device-specific fields, thus easing manufacture without proportionally increasing complexity.

AI summary
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.
