The patent US12036013B2 outlines a sophisticated system designed to maintain the chain of custody during breath analysis procedures. Central to this system is a recording device manager that includes a receiver, memory for data storage, and a processor. This manager is connected to a handheld breath analyzer equipped with a wireless communication element for transmitting signals, a processor for analyzing breath samples, and a proximity tag reader. The proximity tag reader detects tags that can provide data on the location of the breath analyzer and its administrator, ensuring that the analysis is conducted under proper oversight. The system also allows for the integration of video recording devices to capture visual data during the analysis, which can be stored alongside proximity data for comprehensive documentation.

Additionally, the system incorporates methods for analyzing breath samples and managing data related to proximity tags, which may be associated with vehicles or personnel, such as police officers. The proximity tag reader can determine the distance to the tag, enhancing the reliability of the data collected. Peripheral sensors, including video cameras, can be activated to record additional context during the breath analysis, with all data being stored in the recording device manager. This multi-faceted approach not only strengthens the integrity of the breath analysis process but also facilitates the secure storage of results and associated metadata, thereby supporting legal and procedural compliance in law enforcement and other applications.
