Patent number: 7831150Abstract: A combat IFF system, for use in a combat exercise or on the battlefield, including a helmet-mounted passive IFF response unit and a weapon-mounted IFF interrogatory unit for each soldier. Infrared (IR) signals are employed for both challenge and response.

Patent number: 4451146Abstract: A test device for determining the extinction value of a laser range finder having a laser transmitter and a laser receiver characterized by the device having an optical shield for shielding an unattenuated laser beam from the transmitter, a filter chamber containing attenuation filters being disposed in the optical beam path, a scatter unit having a dispersion disk having a scattering range for diffusely scattering the laser light, an optical coupling unit for coupling light into the laser receiver and at least one light waveguide line of a specific length having one end disposed in the scatter range of the dispersion disk and the other end for releasing the light traveling in the waveguide into an optical beam so that the laser light pulses from the transmitter are both attenuated and scattered prior to being coupled into the receiver. The test device enables checking the system sensitivity of laser range finders.Type: GrantFiled: September 11, 1981Date of Patent: May 29, 1984Assignee: Siemens AktiengesellschaftInventors: Ludger Grage, Werner Ryseck

Patent number: 4391514Abstract: The object of the invention is to provide an improved laser altimeter for a flight simulator which will allow measurement of the height of the simulator probe above the terrain directly below the probe tip.A laser beam 22 is directed from the probe 13 at an angle .theta. to the horizontal to produce a beam spot 20 on the terrain. The angle .theta. that the laser beam 22 makes with the horizontal is varied so as to bring the beam spot into coincidence with a plumb line 18 coaxial with the longitudinal axis of the probe 13. A television altimeter camera 30 observes the beam spot and has a raster line aligned with the plumb line 18. Spot detector circuit 26 coupled to the output of the TV camera monitors the position of the beam spot relative to the plumb line 18. An error signal is produced by computer 28 driving, via a servo motor 23, the laser beam optics so as to cause the beam spot to come into coincidence with the plumb line 18.Type: GrantFiled: February 13, 1981Date of Patent: July 5, 1983Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Larry D.

Patent number: 4342514Abstract: Apparatus and method for using one laser range finder to calibrate another imilar range finder. The range finder under test receives a simulated return pulse from the transmitter of the second range finder. An external trigger initiates the transmitter of the range finder under test and a short time later initiates the transmitter of the second range finder. The transmitted beam of the second range finder is directed into the receiver of the range finder under test and it halts the range readout thereof. This range readout is compared to the reading on an external timer arranged to measure the time interval between the emission of the transmitted beams of the two range finders.Type: GrantFiled: August 11, 1980Date of Patent: August 3, 1982Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Paul B.

Patent number: RE45525Abstract: A method of providing a user with an extra-terrestrial somatosensory experience includes equipping the user with an underwater breathing apparatus, having the user occupy an underwater environment, such environment providing buoyancy to the user, and while the user occupies the underwater environment, using a computer-implemented virtual reality system to present to the user a virtual reality environment modeling an extra-terrestrial setting. The virtual reality system inhibits visual perception by the user of items outside of the virtual reality environment so that the user experiences the virtual reality environment under a buoyancy condition provided by the underwater environment. The buoyancy condition enhances the experience of the virtual reality environment.Type: GrantFiled: June 5, 2014Date of Patent: May 19, 2015Assignee: Soarealm, Inc.Inventor: Quan Xiao
