Abstract

A person identification device 100 has a tag 110 with a code and a tamper evident tether 120 able to secure the tag 110 to a person having a body. The person identification device also has a signal generator 140 able to generate a signal representing the code. The tag 110 has a capacitive contact 130 able to capacitively couple the signal into the body of the person.

Claims

1. A breathalyzer comprising:

a sample tube configured to receive a specimen of breath from a person, the sample tube comprising a capacitive contact able to capacitively couple a signal from a body of the person providing the specimen of breath, wherein the signal represents a code associated with the person using the breathalyzer to provide the specimen of breath;

a receiver configured to receive, from the capacitive contact, the signal representing the code; and

a controller configured to determine the code from the signal.

2. The breathalyzer claim 1, wherein the controller is further configured to compare the code against a code database for determining the identity of the person, whereby the identity of the person can be sent by the breathalyser to a monitoring center.

3. The breathalyzer of claim 2, wherein in the event that the breathalyzer fails to determine the identity of the person, an alarm condition is triggered.

4. The breathalyzer of claim 1, further comprising a camera configured to capture an image or video of the person.

5. The breathalyzer of claim 1, wherein the signal representing the code is represented by a modulated signal, and wherein the breathalyzer further comprises a demodulator to determine the code from the signal.

6. The breathalyzer of claim 1, wherein the sample tube is made of plastic and the capacitive contact is formed from a conducting material disposed in the plastic material.

7. A person identification system comprising:

a person identification device comprising;

a tag;

a tamper evident tether able to secure the tag to a person who is to provide a specimen of breath, the tag having a code associated with the person;

a signal generator able to generate a signal representing the code; and

the tag having a first capacitive contact able to capacitively couple the signal into a body of the person; and

a breathalyzer comprising;

a sample tube configured to receive a specimen of breath from the person, the sample tube comprising a second capacitive contact able to capacitively couple the signal from the body of the person providing the specimen of breath, wherein the signal represents the code associated with the person using the breathalyzer to provide the specimen of breath;

a receiver configured to receive, from the second capacitive contact, the signal representing code; and

a controller configured to determine the code from the signal and to compare the code against a code database for the identity of the person providing the specimen of breath.

8. The person identification system of claim 7, further comprising a monitoring center, wherein the identity of the person using the breathalyzer is sent to the monitoring center.

9. The person identification system of claim 8, wherein the event that the breathalyzer fails to determine the identity of the person, an alarm condition is triggered.
