摘要:
A system and method instantly on-site analyze seismic acceleration signals measured from a primary wave of an earthquake and at a detecting site. The system includes an embedded computing host and a signal preprocessing module. Hardware preprocessing is executed on the seismic acceleration signals; and whether the earthquake is a seismic event is able to be determined according to a seism determining logic. Seismic acceleration signals are converted into ground velocities and ground displacements to obtain a peak ground displacement. A seismic fracture time parameter is calculated through the ground velocities and ground displacements and then a seismic magnitude of the earthquake is obtained. According to the peak ground displacement and the seismic magnitude, an epicentral distance is further calculated. Then a peak ground acceleration of the earthquake's shear wave at the detection site is able to be obtained through the seismic magnitude and the epicentral distance.

Various embodiments of a patch antenna, element thereof and method of feeding therefor are described. In general, the patch antenna is configured to generate orthogonal beams and comprises an array of patch elements each contributing to the orthogonal beams and comprising one or more resonators, a base reflector, and a dual feed mechanism. The dual feed mechanism generally comprises two pairs of feeding elements, each one of which comprising substantially balanced feeds configured to drive a respective one of the orthogonal beams via substantially anti-phase capacitive coupling.

A method of filling gaps between gates with doped flowable pre-metal dielectric (PMD) and the resulting device are disclosed. Embodiments include forming at least two dummy gates on a substrate, each dummy gate being surrounded by spacers; filling a gap between adjacent spacers of the at least two dummy gates with a flowable PMD; implanting a dopant in the flowable PMD; and annealing the flowable PMD. Doping the flowable PMD prevents erosion of the PMD, thereby providing a voidless gap-fill.

A filter cartridge is provided that is designed to actuate a valve that controls fluid flow into an outlet for discharging filtered fluid. The valve receives a ball at a first position which is axially movable between the first position and a second position. If a filter cartridge is not installed or an inappropriately designed filter cartridge is installed, the ball is moved from the first position to the second position to seal an outlet opening of the outlet. If the described filter cartridge is installed, the ball is retained at the first position by a holding member and the valve allows filtered fluid flow into the outlet opening.

Solid absorbent materials that are useful for absorption of chemical species from a fluid, such as a gas stream or a liquid stream. The absorbent materials are formed by spray processing and posses a well-defined chemical composition and microstructure. The absorbent materials can have a high absorption capacity for a chemical species such as H2S, CO2, NOx, and H2 and have a high recylability, such that the chemical species can be absorbed and desorbed over a large number of cycles.

The present invention relates to oligonucleotide sequences for amplification primers and detection probes and their use in nucleic acid amplification methods for the specific detection of clinically relevant CYP2D6 polymorphisms, in particular CYP2D6 polymorphisms associated with adverse drug response. The oligonucleotide sequences are also provided assembled as kits that can be used to predict how an individual will respond to drugs or other xenobiotic compounds that are metabolized, at least in part, by CYP2D6.

A zirconia-containing composition and processes for synthesizing same. The composition comprises least about 99.9 percent tetragonal phase zirconia, based on the total crystalline zirconia in the zirconia-containing composition as determined by x-ray diffraction (XRD). The composition also has a substantially spherical morphology and comprises less than 100 wppm chlorine, based on the total weight of the zirconia-containing composition. The zirconia-containing composition has an average surface area of at least 80 m2/g and an average particle size of less than about 10 microns.

Materials that are useful for absorption enhanced reforming (AER) of a fuel, including absorbent materials such as Group 1 and Group 2 metal oxides that are adapted to absorb CO2 and catalyst materials such as reforming catalysts and water-gas shift catalysts, and methods for using the materials. The materials can be fabricated by spray processing. The use of the materials in AER can produce a H2 product gas having a high H2 content and a low level of carbon oxides.
摘要:
A structure of a vacuum adsorbing working platform includes a lower body and an upper body. The lower body has a plurality of channels, and the top of the lower body has a plurality of cross grooves which extend transversely and longitudinally. The channels communicate with the grooves, and they connect to an induction pump. The upper body attached on the lower body has a plurality of ventilation holes passing through the upper body and relative to the grooves, thereby the structure of the working platform is formed which provides better suction.
