Abstract: Small heat shock proteins, e.g., Pyrococcus fuiosus (Pfu-sHSP and/or Pfu-tsHSP), confer thermotolerance on cellular cultures and on proteins in cellular extracts during prolonged incubation at elevated temperature, demonstrating the ability to protect cellular proteins and maintain cellular viability under heat stress conditions. Such heat shock proteins are effective to combat enzymatic aggregation and intracellular precipitation during heat stress, and thereby enable enhancement of the utility and stability of enzymes in various applications, e.g., Taq polymerase in PCR applications, digestive enzymes in microbial degradative applications, etc.

Abstract: An intersection controlled by an intersection controller receives trigger signals from on-coming emergency vehicles responding to an emergency call. The intersection controller initiates surveillance of the intersection via cameras installed at the intersection in response to a received trigger signal. The surveillance may begin immediately upon receipt of the trigger signal from an emergency vehicle, or may wait until the intersection controller determines that the signaling emergency vehicle is in the field of view of the cameras at the intersection. Portions of the captured images are tagged by the intersection controller based on tag signals transmitted by the vehicle or based on detected traffic patterns that indicate a potential traffic violation. The captured images are downloaded to a processing facility that analyzes the images and automatically issues citations for captured traffic violations.

Abstract: A method and system for measuring heat energy of a combustible fluid in which light having wavelengths in the near-infrared is directed into a test cell containing the combustible fluid and portions of the light not absorbed by the combustible fluid and passing out of the cell are spatially dispersed by wavelength, forming a light spectrum that is projected onto a detector. The light spectrum is digitized and inputted into a data processing unit in which it is compared to the actual spectrum of the light source stored in the system to determine the absorbance spectrum of the combustible fluid. The system is spectrally calibrated by identifying known spectral features of the combustible gas absorbance spectrum. To correct for deviations in the original light source spectrum, a light source calibration system is employed.
Abstract: In a cross-wound bobbin (1), the helical lines along which the yarn (4) is wound have a different inclination in adjacent layers. The winding ratios are selected such that the quantity drawn off is greater if the unwinding point is moving from the unwinding end to the bottom end, compared to the quantity drawn off if the unwinding point is moving from the bottom end to the unwinding end.

Abstract: Provided is an optical deflector for deflecting radiation beams. The optical deflector includes: a peripheral region having a first effective refractive index; and a deflection pattern region having a predetermined shape and a second effective refractive index, wherein the second effective refractive index differs from the first effective refractive index. Here, due to the deflection pattern region having the predetermined shape, the radiation beams are deflected in a direction starting from a certain point. By using the optical deflector, the locus of a light source can be designed in one of various forms, such as a straight line, a circle, an ellipse, or a parabola.

Abstract: A teleoperator system with telepresence is shown which includes right and left hand controllers (72R and 72L) for control of right and left manipulators (24R and 24L) through use of a servomechanism that includes computer (42). Cameras (46R and 46L) view workspace (30) from different angles for production of stereoscopic signal outputs at lines (48R and 48L). In response to the camera outputs a 3-dimensional top-to-bottom inverted image (30I) is produced which, is reflected by mirror (66) toward the eyes of operator (18). A virtual image (30V) is produced adjacent control arms (76R and 76L) which is viewed by operator (18) looking in the direction of the control arms. Use of the teleoperator system for surgical procedures also is disclosed.
Abstract: The present invention relates to a non-linear optical material having a dendrimer structure; and, more particularly, to a non-linear optical material having organic chromophores at the ends and formed based on ester linkages and/or ether linkages. Since the non-linear optical material of the present invention is formed based on ester linkages and/or ether linkages, it is very stable. Also, because it is a dendrimer structure, it has the properties of a polymer while having a strong connection ability at the ends, and this makes the non-linear optical material easily adopt organic chromophores easily. As it is stable thermally and optically, it can be applied to optical communication usefully.

Abstract: A method for converting hydrocarbon fuels to hydrogen and carbon monoxide through catalytic partial oxidation is described. The process comprises a reactor containing both an electrically heated catalyst as a start-up device and novel-metal-washcoated metallic monolith catalysts and a heat exchanging device. The partial oxidation reaction becomes ignited in less than 1.5 minute when the gaseous hydrocarbon fuel and oxygen-containing gas mixture is in contact with an electrically heated catalyst. The reaction takes place over the metallic monolith catalyst washcoated with noble metal (typically Pd/alumina-cerium oxide). The near complete conversion of hydrocarbon fuels with high hydrogen and carbon monoxide selectivities is achieved by preheating the feed mixture heat-exchanged with hot product gas stream.
