Identification system
First Claim
1. An identification system comprising:
- a laser device which is capable of emitting a laser beam with a first code and a laser beam with a different second code;
a target device having a sensor for detecting said first and second coded laser beams from said laser device, a microprocessor for formulating a response, a laser response transmitter and a radio frequency or ultrasound response transmitter; and
, receivers associated with said laser device which are collectively capable of receiving a laser response and either a radio frequency or ultrasound response from said target device;
wherein said laser device initially emits said laser beam with a first code to said target device to solicit a laser response and, if said laser device does not receive a laser response from said target device within a predetermined period of time after transmission, said laser device then emits said laser beam with a second code to solicit either a radio frequency or ultrasound response.

Abstract
A soldier (A) carries a weapon, on which a laser device (1) is mounted, which is used for illuminating a harness device (6) on the body of another soldier (B). The laser device and the target device each include a microprocessor as well as an ultrasound unit and/or a radio unit (72, 71) such that, if the laser device does not receive a response from the target device within a period of time Ta following the transmission of a bundled, coded laser beam, it transmits another laser beam with different coding, which causes the ultrasound unit and/or the radio unit of the target device to transmit an acknowledgement which can be received by the ultrasound unit and/or the radio unit of the laser device.

3. An identification system comprising:
-
a laser device which is capable of emitting a tightly bundled laser beam with a first code and a tightly bundled laser beam with a different second code which are both visible only through night vision goggles;
a target device having a sensor for detecting said first and second coded laser beams from said laser device, a microprocessor for formulating a response, a laser response transmitter and a radio frequency or ultrasound response transmitter;
receivers associated with said laser device which are collectively capable of receiving a laser response and either a radio frequency or ultrasound response from said target device; and
,an alert device associated with said laser device which can alert the user of said laser device whether the user of said target device is friendly or not, wherein said laser device initially emits said laser beam with a first code to said target device to solicit a laser response and, if said laser device does not receive a laser response from said target device within a predetermined period of time after transmission, said laser device then emits said laser beam with a second code to solicit either a radio frequency or ultrasound response.
