Abstract

A method and system for monitoring a user's intoxication including receiving a set of signals, derived from a set of samples collected from the user at a set of time points; providing a sobriety task to the user proximal to a time point of the set of time points; generating a performance dataset characterizing performance of the sobriety task by the user; receiving a supplementary dataset characterizing a demographic profile of the user and/or a physiological state of the user; determining a set of values of an intoxication metric, derived from the set of signals; generating a predicted temporal profile of the intoxication metric for the user based upon the set of values, the set of time points, and the supplementary dataset; generating an analysis of the user's sobriety based upon the performance dataset and the predicted temporal profile; and providing a notification to the user based upon the analysis.

First claim

We claim:

1 . A system for monitoring intoxication of a user, the system comprising:
a housing positioned adjacent to the user during operation of the system, wherein the housing receives a sample from the user; an electronics system coupled to a wrist-borne device, wherein the electronics system comprises a sensor and is at least partially disposed within the housing, and wherein the electronics system determines a signal based on the sample; a data link coupled to the electronics system and to a processing system, wherein a first portion of the processing system is arranged at the housing and a second portion of the processing system is arranged at a mobile computing system arranged at the wrist-borne device, and wherein the processing system:
receives the signal from the electronics system through the data link; and
determines a value of an intoxication metric, derived from the signal.

2 . The system of claim 1 , wherein the wrist-borne device comprises a vibration motor electrically connected to the electronics system, wherein a second notification comprising a haptic output is provided at the vibration motor.

3 . The system of claim 1 , where the sample is a breath sample.

4 . The system of claim 1 , wherein the sensor is a fuel cell sensor.

5 . The system of claim 1 , wherein the processing system further generates a notification, wherein the notification is provided at a display of the mobile computing system.

6 . The system of claim 5 , wherein the notification comprises at least one of a predicted count of total drinks consumed by the user and a predicted peak intoxication metric of the user.

7 . A system for monitoring intoxication of a user, the system comprising:
a housing positioned adjacent to the user during operation of the system, wherein the housing receives a sample from the user; an electronics system coupled to a wrist-borne device, wherein the electronics system comprises a sensor and is at least partially disposed within the housing, and wherein the electronics system determines a signal based on the sample; a data link coupled to the electronics system and to a processing system, wherein the processing system:
receives the signal from the electronics system through the data link; and
determines a value of an intoxication metric, derived from the signal.

8 . The system of claim 7 , wherein the processing system further generates a notification based on the intoxication metric.

9 . The system of claim 8 , wherein the notification comprises at least one of a predicted count of total drinks consumed by the user and a predicted peak intoxication metric of the user.

10 . The system of claim 8 , further comprising a client application executing on a mobile user device, wherein the notification is provided at the client application.

11 . The system of claim 10 , wherein the mobile user device is coupled to the wrist-borne device.

12 . The system of claim 11 , wherein the client application is further executing on a second mobile user device, wherein the second mobile user device is in communication with the electronics system and arranged offboard the wrist-borne device.

13 . The system of claim 7 , wherein the wrist-borne device comprises a fastener coupled to a digital watch face.

14 . The system of claim 13 , wherein at least a portion of the processing system is arranged within a housing of the digital watch face.

15 . The system of claim 7 , wherein at least a portion of the processing system is arranged at the housing.

16 . The system of claim 15 , wherein a remaining portion of the processing system is arranged at computing system arranged onboard the wrist-borne device.

17 . The system of claim 7 , wherein the processing system is arranged onboard the wrist-borne device.

18 . The system of claim 7 , wherein the sample is a breath sample.

19 . The system of claim 7 , wherein the wrist-borne device comprises a vibration motor electrically connected to the electronics system, wherein a second notification comprising a haptic output is provided at the vibration motor.

20 . The system of claim 7 , wherein the sensor is a fuel cell sensor.
