Method and system for monitoring intoxication

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.

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.
