1. A blood alcohol monitoring device for continuous remote monitoring of a human subject comprising:

  • a processing means;

    an alcohol sensor means connectable to said processing means for taking a plurality of transdermal alcohol concentration readings at predetermined times without active participation by the human subject;

    a drawing means connectable to said processing means for drawing a consistent and predetermined sample across said alcohol sensor means during each of said taking of said plurality of transdermal alcohol concentration readings;

    an infrared sensor means connectable to said processing means for taking a plurality of distance readings used for detecting an obstruction between the blood alcohol monitoring device and a portion of skin of the human subject or removal of the blood alcohol monitoring device from the human subject;

    a temperature sensor means connectable to said processing means for taking a plurality of temperature readings of said sample from the human subject;

    a radio frequency transceiver means connectable to said processing means for transmitting said plurality of transdermal alcohol concentration readings, said plurality of distance readings, and said plurality of temperature readings through radio frequency signals;

    a first housing containing said processing means and said radio frequency transceiver means;

    a second housing containing said alcohol sensor means, said drawing means, said infrared sensor means, and said temperature sensor means;

    a flexible circuit connecting said first housing to said second housing;

    an elastic strap connecting said first housing to said second housing;

    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.
