Abstract: An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared.

Abstract: A method and device for determining the depth and fluorophore concentration of a fluorophore concentration below the surface of an optically absorbing and scattering medium suitable for use in fluorescence-based surgical guidance such as in tumor resection is described. Long-wavelength stimulus light us used to obtain deep tissue penetration. Recovery of depth is performed by fitting measured modulation amplitudes for each spatial frequency to precomputed modulation amplitudes in a table of modulation amplitudes indexed by optical parameters and depth.

Abstract: A portable multi-tube air sampler device for capturing samples of trace elements in a suspected contaminated environment which includes a plurality of sample tubes for collecting sample trace elements, parallel inlet and outlet manifolds which minimize the length of the sample inlet path while utilizing short straight sample tubes, a hinged retainer bar mechanism which allows for easy removal and replacement of the various sample tubes, and a removably attachable controller unit which can be installed on the exterior portion of the carrying case for controlling the operation of the sampling protocol. Other embodiments include heated inlet manifold and sample intake paths to prevent contamination accumulation and carryover, a clean cycle option with a filter valved into the inlet flow path to enhance the purging cycle, and a mechanism for converting the present device to a desorbing auto sampler configuration. The present system likewise incorporates a purging cycle prior to each sampling cycle.

Abstract: An improved in intake manifold for a carbureted, vee type of internal combustion engine is comprised of at least two members, a fuel-oxidizer flow member and an isolator member. The flow member is removably connected to the isolator member. The isolator member is connected at a bottom surface to a vee valley of the internal combustion engine formed between opposing banks of cylinders. In a preferred embodiment, the flow member is sealingly split along a longitudinal axis of the engine. The isolation member isolates the flow member from the environment existing in the vee valley while sealing the vee valley. Engine coolant passages and a distributor shaft opening are provided within the isolator. Changing the flow member is accomplished without disturbing the vee valley sealing, the distributor setting, nor the engine cooling conduits.

Abstract: A carburetor spacer is provided with an isolation member to isolate the flow of atomized fuel from a carburetor to an intake manifold of an internal combustion engine comprising first and second hollow members fitting one inside the other and an elastomeric member interposed between said fitted hollow members. The elastomeric member also serving to thermally insulate the flow of fuel-oxidizer from heat produced by the engine. Thus, the isolation member helps prevent the fuel from reverting to a liquid state before being introduced into the cylinders of the engine and by reducing the heat input to the fuel-oxidizer mixture, less expansion of the mixture occurs before being introduced into the engine's cylinders. Less expansion results in more of the mixture of the fuel-oxidizer can be input to the cylinders resulting in a greater power output by the engine.

Abstract: A testing apparatus connects to an inflatable restraint and simulates the inflation curve of a pyrotechnic device used in a vehicle. A manifold connects the inflatable restraint to a pair of parallel accumulators for communicating a gas to the inflatable restraint. The accumulators store gas at a high pressure. A valve is connected and interposed between each of the accumulators and the manifold for releasing the flow of the gas out of the accumulators. An adjustable orifice is connected and interposed between each of the valves and the manifold for regulating the flow of the gas out of the accumulators. A flow shut off device is connected to the manifold and is interposed between the accumulators and the inflatable restraint and is adapted for stopping the flow of gas from the first and second accumulator to the inflatable restraint.
