摘要： Methods and apparatus for providing a tunable absorption-emission band in a wavelength selective device are disclosed. A device for selectively absorbing incident electromagnetic radiation includes an electrically conductive surface layer including an arrangement of multiple surface elements. The surface layer is disposed at a nonzero height above a continuous electrically conductive layer. An electrically isolating intermediate layer defines a first surface that is in communication with the electrically conductive surface layer. The continuous electrically conductive backing layer is provided in communication with a second surface of the electrically isolating intermediate layer. When combined with an infrared source, the wavelength selective device emits infrared radiation in at least one narrow band determined by a resonance of the device. In some embodiments, the device includes a control feature that allows the resonance to be selectively modified. The device has broad applications including gas detection devices and infrared imaging.

摘要： A portal is provided with a detector for detecting trace amounts of substances of interest that may be retained on the surface or interior of a vehicular subject. The portal relies upon the continuous process by which microscopic flakes of dust, dirt, pollen, and other surface and interior contaminants as well as adsorbed analyte media and analyte vapors continuously separate from the surface of vehicular subjects and escape from the interior of vehicular subjects. The portal further leverages the existence of a vehicular thermal plume consisting of a layer of warm air adjacent to the vehicular subject. The warm air rises in the cooler surrounding air and transports the microscopic flakes of surface contaminants, desorbed analyte, and analyte vapors upwardly. The portal capitalizes on this phenomenon by providing at least a partial enclosure with a funnel-shaped collector above the vehicular subject. A low speed flow of relatively dense cool air may be introduced into the portal to buoyantly lift the warmer air of the vehicular thermal plume upwardly. The air stream defined by the vehicular thermal plume and the contaminant particles, analyte media, and analyte vapors therein moves to a trap in the funnel-shaped collector above the portal. The trap cooperates with a detector for detecting the presence of molecules of interest.

摘要： A method for separating the orthogonal polarization components of an incident optical signal into two spatially separated output ports is described. The method comprises a Mach-Zehnder interferometer where one of the two branches has a section of waveguide that exhibits form-birefringence. This integrated optic Polarization Beam Splitter (PBS) is broadband, has high extinction ratio, and has characteristics that are tunable.

Materials of the present invention may include emissive, photostable organic molecules (e.g., conjugated polymers, conjugated oligomers) that are appropriately functionalized to interact with a cell with essentially no disruption in normal cell functioning. The present invention may be useful in, for example, cell imaging, cell tracking, in vivo monitoring of cellular events, drug delivery, and determination of biological species. In one embodiment, a conjugated polymer or oligomer may be internalized into a cell and may exhibit a strong and stable emissive signal, allowing the cell to be monitored under extensive microscopic conditions for extended periods of time.

摘要： A system for providing reliable, unalterable mechanical data associated with the mechanical properties of a concrete mass. The system includes a logger, a second memory device and an outbound data transfer device. The logger is provided with one or more sensors, a microprocessor and a first memory device. The one or more sensors measure physical properties of the concrete mass and generate data associated with the physical properties. The microprocessor receives the data from the sensor and calculates maturity data and mechanical strength data. The first memory device stores the mechanical strength data within the concrete mass in an unalterable form. The second memory device is located outside the concrete mass. The outbound data transfer device transfers the mechanical strength data from the first memory device to the second memory device.
