Abstract
A location determination device (104) is worn on a user's head to facilitate searching and tracking for another individual carrying a portable radio (102) as well as locating exit routes. At least two antennas (108), a monopulse receiver (110) and a display are integrated into the location determination device (104). Location determination device (104) scans for an incoming signal (106) from the portable device (102) and coverts the signal into angular location data. The location data and egress information are displayed to the peripheral vision of the user of the location determination device (104).
Claims18
A helmet, including:
- a monopulse receiver for receiving a signal generated from a portable radio;
- a controller coupled to the monopulse receiver, the controller generating a control signal in response to the received signal;
- and
- a head's-up-display (HUD) coupled to the controller and responsive to the control signal, the HUD indicating a location of the portable radio to a wearer of the helmet via the wearer's peripheral vision.
A portable communication device, including:
- a housing to be worn on a user's head;
- a plurality of antennas integrated within the housing for receiving signals transmitted from a remote device;
- a monopulse receiver coupled to the plurality of antennas and providing angular location data of the remote device in response to the received signals;
- a controller for converting the angular location data into a corresponding control signal;
- and
- a display controlled by the controller, the display being updated to indicate to the user a location of the remote device.
A helmet, including:
- an antenna array;
- a monopole receiver coupled to the antenna array for receiving a transmitted signal from a remote device, the remote device being either stationary or mobile;
- and
- a display coupled to the controller, the display indicating and dynamically updating a location of the remote device to a wearer of the helmet.
A communication system, comprising:
- a portable radio generating a transmit signal;
- a helmet to be worn by a user, the helmet including:
- a plurality of antennas receiving the transmit signal;
- a receiver converting the transmit signal into angular location data;
- and
- a display indicating the angular location data to the user's peripheral vision.
A communication system, including:
- a housing to be worn on a user's head;
- an antenna array coupled to the housing;
- a monopulse receiver coupled to the antenna array for receiving signals pertaining to angular location of a second party with respect to the user and egress data;
- a controller for converting the angular location and egress data into control signals;
- and
- a head's-up-display (HUD) coupled to the controller, the HUD indicating and dynamically updating the angular location and egress data to the user's peripheral line of vision in response to the control signals.
