Abstract: A method of detecting changes in a scene comprising placing a fluorescent and/or phosphorescent compound in the scene and monitoring for elimination or change in position of the phosphorescent compound. Also a liquid fluorescent and/or phosphorescent material comprising one or more compounds that are fluorescent and/or phosphorescent in infrared frequencies and substantially not fluorescent and/or phosphorescent in visible light frequencies and a carrier.

Abstract: A method for embedding optical band gap (OBG) devices in a ceramic substrate (100). The method includes the step (320) of pre-forming an OBG structure (105). The OBG structure can be a micro optical electromechanical systems (MOEMS) device. Further, the OBG structure can be preformed from indium phosphide and/or indium gallium arsenide. The method also includes the step (325) of coating the OBG structure with a surface binding material (230). The surface binding material can be comprised of calcium and hexane. The ratio of the calcium to hexane can be from about 1% to 2%. At a next step (330), the OBG structure can be inserted into the ceramic substrate. A pre-fire step (335) and a sintering step (340) then can be performed on the substrate.

Abstract: An optically active composition (100) for optical applications has been identified. The optically active composition (100) can include at least one cyclic molecule having a nanocore (112) disposed within the cyclic molecule to form a filled ring (108). The composition (100) is optically transmissive for at least one photonic wavelength that would not otherwise be transmitted by the composition (100) if the nanocore were absent from the cyclic molecule. The cyclic molecule can be a carbon ring, an aromatic ring, or a heterocyclic ring. The filled ring (108) can be attached to a chiral molecule which is a repeat unit (102) in a polymeric backbone. A second filled ring (110) which causes the composition to be optically transmissive at a second wavelength also can be attached to the chiral molecule (102) as well. An electric field can be applied to the filled ring (108) to adjust the wavelength at which filled ring (108) is transmissive.

Abstract: An RF system (100) can include one or more RF circuits (108) coupled to a fluid dielectric (106). The RF circuit can be disposed on a portion of a dielectric substrate (102) which also contains the fluid dielectric. A light source 302 is provided for transmitting optical radiation through a portion of the fluid dielectric in a transmitted direction. A sensor (304) measures at least one parameter indicative of a change of direction of the optical radiation relative to the transmitted direction. According to one aspect, the light source and/or the sensor can be disposed within the dielectric substrate of the RF system. An output of the sensor can be coupled to a processor (322, 422) for determining a condition of the fluid dielectric based on the measured parameter.

Abstract: A method for making an electronic device includes positioning first and second members so that opposing surfaces thereof are in contact with one another, the first member comprising silicon and the second member comprising a low temperature co-fired ceramic (LTCC) material. The method further includes anodically bonding together the opposing surfaces of the first and second members to form a hermetic seal therebetween. The anodic bonding provides a secure and strong bond between the members without using adhesive. The method may further include forming at least one cooling structure in at least one of the first and second members. The least one cooling structure may comprise at least one first micro-fluidic cooling structure in the first member, and at least one second micro-fluidic cooling structure in the second member aligned with the at least one first micro-fluidic cooling structure.
