  • Patent number: 8508128
    Abstract: In accordance with an aspect of the invention, there is provided a thermal radiation marker (10) adapted to emit radiation within the thermal portion of the infrared spectrum. According to some embodiments of the invention, the thermal radiation marker may include an incandescent filament (16) and a glass or quartz enclosure (12). The incandescent filament may be adapted to produce radiation at least within the thermal portion of the infrared spectrum. The glass or quartz enclosure may include at least a portion that is substantially thin, and may enclose pressurized inert (14) gas and the incandescent filament surrounded by the inert gas. At least a portion of the glass or quartz enclosure may be sufficiently thin so as to enable good transmittance therethrough for tli3rmal radiation approximately in the 3-5&mgr,-m wavelength band.

  • Patent number: 8103167
    Abstract: A free space optical communication system is described that comprises a receiver node and a transmitter node communicating to each other via a control data communication channel and an information data communication channel operating at a wavelength region different from the wavelength region of the control data communication channel. The receiver node includes a receiver unit configured to receive an information data signal provided by the transmitter node through the information data communication channel, and to recover information from said information data signal; an interrogator unit configured for generating and radiating an interrogation data signal through the control data communication channel in order to initiate and terminate an information data communication session between the receiver node and the transmitter node; and a receiver node controller configured for controlling operation of the receiver unit and the interrogator unit.
