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.
Claims14
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.
2 more elements
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.
3 more elements
An identification system comprising:
- a laser device having a laser target illuminating device, a housing element with batteries and a mounting rail for connecting the laser device elements together wherein said laser device 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;
- 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,
- parallel extending, partially cylindrical parts on said laser device that a laser device user can use to aim along a gap between said parts and see an alert light between said parts for identifiing 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.
3 more elements
A target device for an identification system comprising
- a portable harness device having a laser transmitter, light detector and regulating unit,
- wherein said regulating unit has a memory for storing a harness system identification code, a display, a battery, a keyboard capable of data input and preparing messages, and a control circuit for transmitting both said identification code and any messages by way of radio signals, ultrasound signals, light signals or cable.
