a conductive strap connecting said second housing to said first housing, wherein said first housing, said flexible circuit, said elastic strap, said second housing, and said conductive strap form a bracelet;
a battery housing insertable in an enlarged channel in said first housing;
a battery insertable in said battery housing for supplying power to the blood alcohol monitoring device;
a battery clip insertable in said enlarged channel and lockably engageable with said battery housing, wherein said battery housing lockably engaged with said battery clip within said enlarged channel is adapted to securely attach the blood alcohol monitoring device to a limb of the human subject;
a continuous signal passed through said first housing, said flexible circuit, said second housing, and said conductive strap, wherein said continuous signal confirms passive identification of the human subject, and further wherein a disruption of said continuous signal indicates that a tamper condition exists;
a modem in communication with the blood alcohol monitoring device through said radio frequency signals, wherein when said tamper condition exists, the blood alcohol monitoring device attempts to communicate said tamper condition to said modem through said radio frequency signals;
an integrated memory connectable to said processing means; and
a communication schedule stored in said integrated memory, wherein the blood alcohol monitoring device attempts to communicate with said modem at times designated in said communication schedule, and further wherein, when the blood alcohol monitoring device fails to communicate with said modem at a scheduled communication time, said modem generates a communication alert along with a date and time of the failed communication, and further wherein, when the blood alcohol monitoring device fails to communicate with said modem for a predetermined period of time, said modem generates a no monitor communication alert along with a present date and time.

Abstract
A tamper proof transdermal alcohol content monitoring device is made up of analog and digital sides which are securely attached to the human subject to be monitored. The analog side has a sampling circuit which draws a measured insensible skin perspiration sample from the skin of the subject and measured with an electrochemical fuel cell. A distance measurement of the device from the skin of the subject and temperature of the sample are monitored along with the transdermal alcohol content, and converted to digital signals which are transmitted to a modem when the monitor is in proximity to the modem. The signals are stored in the modem and uploaded to a central monitoring station. Automatic alerts may be sent from the central monitoring station to a supervising agency. The supervising agency may also access the information through secured dedicated websites via the Internet.
