Abstract

A breath analyzer, a system, and a computer program for administering a breath analysis to a donor and recording a breath analysis result. Embodiments of the invention authenticate that the breath analysis was performed correctly, preserves the breath analysis results by communicating with other devices, and presents the breath analysis results by superimposing them on recorded video data. The breath analyzer includes a breath receptor for receiving a breath sample from the donor, an analyzing element for determining a breath analysis result, a communications element for sending information indicative of the breath analysis result to a recording device manager, and a housing for securing the components in a handheld device. The system comprises the breath analyzer, a recording device manager for synchronizing the recordings, and at least one ancillary camera for recording the breath analysis.

First claim

Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1. A system for maintaining chain of custody while administering a breath analysis to a donor, the system comprising:
a recording device manager, including:
a receiver for receiving one or more signals,
a recording device manager memory for storing data and computer-executable instructions; and
at least one recording device manager processor;

a handheld breath analyzer communicatively coupled with the recording device manager,
the handheld breath analyzer including:
a wireless communications element for transmitting the one or more signals to the recording device manager;
at least one breath analyzer processor for analyzing a breath analysis sample to generate breath analysis data; and
a proximity tag reader configured to detect a proximity tag to generate proximity data,
wherein the one or more signals include the breath analysis data and the proximity data.

2. The system of claim 1 , wherein the proximity tag reader is further configured to:
detect a signal strength operable to determine a distance between the proximity tag reader and the proximity tag, and
transmit a signal strength value or a calculated distance to the recording device manager.

3. The system of claim 1 , further comprising at least one video recorder configured to capture video data and transmit the video data to the recording device manager.

4. The system of claim 3 , wherein the recording device manager is configured to store proximity data indicative of the proximity tag together with the video data.

5. The system of claim 1 , wherein the proximity tag is associated with a vehicle and a strength of a proximity tag signal is indicative of a distance between the handheld breath analyzer and the vehicle.

6. The system of claim 1 , wherein the proximity tag is adapted to be attached to a police officer.

7. The system of claim 1 , further comprising at least one peripheral sensor that is activated to begin recording peripheral data when the handheld breath analyzer is activated.

8. The system of claim 7 , wherein the peripheral data is associated with the breath analysis data by metadata and stored at the recording device manager.

9. A system for maintaining chain of custody while administering a breath analysis to a donor, the system comprising:
a recording device manager, including:
a receiver for receiving one or more signals,
a recording device manager memory for storing data and computer-executable instructions; and
at least one recording device manager processor;

a handheld breath analyzer communicatively coupled with the recording device manager,
the handheld breath analyzer including:
a wireless communications element for transmitting the one or more signals to the recording device manager;
at least one breath analyzer processor for analyzing a breath sample to generate a result; and
a proximity tag reader configured to detect a proximity tag;

wherein the proximity tag reader is configured to detect at least one proximity tag associated with an administrator of the handheld breath analyzer, and
wherein the wireless communications element is configured to transmit location data indicative of a relative location of the at least one proximity tag and the result to the recording device manager for storage.

10. The system of claim 9 , wherein the proximity tag reader is further configured to:
detect a signal strength operable to determine a distance between the proximity tag reader and the administrator, and
transmit a signal strength value or a calculated distance to the recording device manager.

11. The system of claim 9 , further comprising:
a peripheral sensor obtaining peripheral data;
wherein the recording device manager is configured to associate the result with the peripheral data obtained from the peripheral data.

12. The system of claim 11 , wherein the peripheral sensor is a video camera mounted on a vehicle.

13. The system of claim 11 , wherein the peripheral sensor is a video camera adapted to be attached to the administrator of the handheld breath analyzer.

14. The system of claim 11 , wherein the result and the peripheral data is transmitted by the recording device manager to an auxiliary storage device.

15. A method of maintaining chain of custody while administering a breath analysis, the method comprising:
receiving, by a handheld breath analyzer, a breath sample;
analyzing, by at least one breath analyzer processor, the breath sample to determine a result of the breath analysis;
receiving, by a proximity tag reader on the handheld breath analyzer, a proximity tag signal from a proximity tag;
transmitting, by a wireless transmitter of the handheld breath analyzer to a recording device manager, proximity tag data indicative of the proximity tag and the result;
receiving, by the recording device manager, the result and the proximity tag data; and
storing, by the recording device manager, the result and the proximity tag data.

16. The method of claim 15 , further comprising:
detecting a signal strength of the proximity tag data;
generating distance data indicative of a distance between the proximity tag reader and the proximity tag; and
storing the distance data indicative of the distance.

17. The method of claim 15 , further comprising:
detecting, by a peripheral sensor, peripheral data; and
storing, by the recording device manager, the peripheral data associated with the result.

18. The method of claim 17 ,
wherein the proximity tag is associated with a police vehicle; and
wherein the peripheral sensor is a video camera mounted on the police vehicle.

19. The method of claim 17 ,
wherein the proximity tag is associated with a police officer; and
wherein the peripheral sensor is a video camera attached to the police officer.

20. The method of claim 15 , wherein the handheld breath analyzer includes a global positioning system (GPS) receiver for determining a location of the handheld breath analyzer.
