Abstract: A device for managing alcohol consumption of a user includes a camera that captures an image associated with a beverage container, a display unit, a memory unit that stores (a) a set of modules, and (b) a database, and (iv) a processor that executes (a) an alcohol content identification module, when executed by the processor, identifies (i) a type of drink in the beverage container and (ii) an alcohol content associated with the drink, (b) an alcohol consumption determination module, executed by the processor, determines an alcohol consumption by the user, (c) an alcohol consumption updating module, when executed by the processor, updates the alcohol consumption by the user in the database, and (d) an alert generation module, when executed by the processor, generates an alert when the alcohol consumption by the user is in proximity with the at least one of periodic threshold.

Abstract: A blood alcohol content (BAC) measurement system powered by an audio signal from a phone is provided. The BAC measurement system includes a sensor unit, a microcontroller and a power extraction unit. The sensor unit includes a fuel cell that generates an electric current when a breath of a user contacts the fuel cell. The microcontroller generates a signal based on the electric current. A frequency of the signal is based on alcohol content in the breath. The power extraction unit powers the sensor unit. The power extraction unit converts the audio signal generated by the phone into power for the microcontroller.
