System and method for determining a time when the blood alcohol concentration has passed a threshold level
First Claim
1. A system operable to determine a future point of time when a user can operate a vehicle, at which the alcohol concentration in blood of a user is less than a threshold value, the system comprises an alcohol sensor operable to detect a current alcohol concentration in blood of the user, and a portable apparatus,wherein the alcohol sensor, and the portable apparatus each independently comprise a wireless communication device, wherein a first wireless communication device in the alcohol sensor is operable to wirelessly transmit the current alcohol concentration to a second wireless communication device in the portable apparatus, andwherein the portable apparatus further comprises a controller, a clock, and a memory, wherein the controller is connected to the second wireless communication device, the clock, and the memory, and the controller is operable to store the current alcohol concentration and a time stamp from the clock in the memory, andwherein the controller is connected to a calculation device operable to calculate the future point of time in dependence of the current alcohol concentration detected by the alcohol sensor and of a known alcohol burn rate of the user stored in the memory means, or an alcohol burn rate calculated by the calculation means in dependence of characteristics of the user which have an influence on the alcohol burn rate, wherein said characteristics of the user are selected from the group consisting of sex and weight and combinations thereof, andwherein the alcohol sensor further comprises a device configured to receive exhalation air from the user, and a fuel cell, andwherein the calculation device is operable to be self-calibrated during use through software comprising formulas that are parameterized to the user.

Abstract
A system operable to determine a future point of time, at which the alcohol concentration in blood of a user is less than a threshold value. The system includes an alcohol sensor operable to detect a current alcohol concentration in blood of the user, and a portable apparatus. The alcohol sensor and the portable apparatus comprises each a wireless communication apparatus. The wireless communication apparatus in the alcohol sensor is operable to wirelessly transmit the current alcohol concentration to the wireless communication apparatus in the portable apparatus.

9. A method for determining a future point of time when a user can operate a vehicle, at which the alcohol concentration in blood of a user is less than a threshold value, the method comprising the steps of:
-
(a) having a user exhale exhalation air into an alcohol sensor comprising a fuel cell; (b) detecting a current alcohol concentration in blood of the user with the alcohol sensor; (c) wirelessly transmitting the current alcohol concentration to a portable apparatus comprising a calculation device; (d) inputting characteristics of the user, which have an influence on the alcohol burn rate selected from the group consisting of sex and weight and combinations thereof, using the portable apparatus; and (e) using; (1) the wirelessly-transmitted current alcohol concentration, and (2) a software that makes use of either; (i) a known alcohol burn rate of the user, or (ii) an alcohol burn rate calculated through use of said software based on characteristics of the user from step (d), which have an influence on the alcohol burn rate, to calculate the future point of time; said method further comprising self-calibrating the calculation device during the method through use of said software;
wherein said software comprises formulas that are parameterized to the user. - View Dependent Claims (10, 11, 12, 13, 14)
