Abstract: An article includes a ceramic-based substrate and a barrier layer on the ceramic-based substrate. The barrier layer includes a matrix of barium-magnesium alumino-silicate or SiO2, a dispersion of silicon oxycarbide particles in the matrix, and a dispersion of particles, of the other of barium-magnesium alumino-silicate or SiO2, in the matrix.

Abstract: A recessed carbon nanotube article includes a base; a substrate disposed on the base; wells disposed in the substrate and bounded by the base and a substrate wall; and a carbon nanotube element disposed in individual wells and including vertically aligned carbon nanotubes such that a longitudinal length of the vertically aligned carbon nanotubes is less than a depth of the well in which the carbon nanotube element is disposed. A recessed carbon nanotube bolometer includes a base; a substrate on the base; radiation wells in the substrate; carbon nanotubes in the wells; thermistors and heaters on the membrane arranged as an electrical substitution member. A process for making a recessed carbon nanotube bolometer includes forming a substrate on a base; forming a radiation well in the substrate; forming carbon nanotubes in the well; disposing a cover on the wells; and forming a thermistor and a heater on the base.

Abstract: Systems and methods for processing and analyzing samples are disclosed. The system may process samples, such as biological fluids, using assay cartridges which can be processed at different processing locations. In some cases, the system can be used for PCR processing. The different processing locations may include a preparation location where samples can be prepared and an analysis location where samples can be analyzed. To assist with the preparation of samples, the system may also include a number of processing stations which may include processing lanes. During the analysis of samples, in some cases, thermal cycler modules and an appropriate optical detection system can be used to detect the presence or absence of certain nucleic acid sequences in the samples. The system can be used to accurately and rapidly process samples.

Abstract: A toilet bowl overflow prevention device is provided including a rigid interconnect member having a top end adapted for being pivotally connected to a knob assembly of a toilet assembly. The interconnect member is adapted for forcing a flush valve of the toilet assembly into sealed abutment with a drain aperture of the toilet assembly when the knob assembly is rotated in a direction opposite of that associated with removing the flush valve from engagement with the drain aperture.

Abstract: A feed system for a dish-type microwave antenna has a primary radiator for directing a primary radiation pattern onto the dish-type antenna. A pair of symmetrical pattern control elements are aligned with the E plane of the antenna and extend radially outwardly from opposite sides of the axis of the primary radiator between the primary radiator and the antenna for increasing the antenna gain, reducing the sidelobe levels and reducing the half power beamwidth of the antenna in both the E and H planes. In an exemplary embodiment, the pattern control elements comprise metal strips mounted on the surface of a rigid coaxial cable extending along the axis of the primary radiator for transmitting microwaves to and from the primary radiator, and the metal strips are inclined toward the antenna.
