摘要:
A tangentially-fired furnace for the burning of anthracite is disclosed. The furnace may contain a boiler with a chamber having four corners. Four burner groups located at the four corners may be configured to eject pulverized coal flow into the chamber for combustion, in order to form a single fireball substantially at the center of the chamber during combustion. Each burner group may contain a first burner which includes primary-air/rich-portion nozzles for ejecting rich-portion coal flow into a lower section of the chamber, and a second burner which includes primary-air/thin-portion nozzles for ejecting thin-portion coal flow into a higher section of the chamber.

Disclosed herein is an X-ray imaging system, comprising: a first X-ray source; an image sensor, spaced apart from the first X-ray source; a table configured to be positioned between the first X-ray source and the image sensor and configured to accommodate a person for imaging in the X-ray imaging system; and a fiducial marker system; wherein the fiducial marker system comprises three markers, centers of the three markers not being collinear; wherein at least one of the three markers is distinct. The X-ray imaging system may be used to model the 3D shape and track the 3D motion of an object (e.g., a surgical instrument) in the person.

This disclosure provides systems, methods, and apparatus related to nanophotonics. In one aspect, an arrangement of waveguides includes a substrate and three waveguides. Each of the three waveguides may be a linear waveguide. A second waveguide is positioned between a first waveguide and a third waveguide. The dimensions and positions of the first, the second, and the third waveguides are specified to substantially eliminate coupling between the first waveguide and the third waveguide over a distance of about 1 millimeter to 2 millimeters along lengths of the first waveguide, the second waveguide, and the third waveguide.

摘要:
An electronic device includes a cage and a fan module. The cage includes a mounting plate defining a ventilation hole. A positioning portion is located in the ventilation hole. A restriction is located on an inner surface of the positioning portion. The height of the restriction is such as to strictly require the fan module to be in the correct orientation when it is fitted to the electronic device.

The invention relates to a method for automatically modularly integrating sensor devices (16) in a central controller (11) of a network having at least one first server comprising at least one first communication module (12) and the central controller (11) for at least one part of the network. The method comprises at least the following steps: a.) determining the sensor devices (16) actually associated with the at least one first server by the at least one first communication module (12); b.) comparing the determined actual sensor devices (16a, 16b) to a quantity of detectable sensor devices defined in a detecting order and determining matching sensor devices (16a); c.) transmitting data associated with the matching sensor devices from the first communication module (12) to the central controller (11); d.) automatically integrating predefined control modules in the central controller (11) based on the transmitted data, wherein the predefined control modules (16a) are each associated with the data of the matching sensor devices. The invention further relates to a device for performing the method, and to a computer program having program code means for performing all the steps of the method.
摘要:
A method of using a Graphic User Interface (GUI) for interactive virtual inspection of modeled objects. The method includes acquiring a three-dimensional model of a modeled object and displaying a first view of the modeled object for a user to identify locations of interest on a surface of the modeled object visible within the first view. The user enters information to create a markup tag that annotates the location of interest, and the markup tag is automatically associated with the location of interest on the modeled object. A second view of the modeled object is displayed including the user identified location of interest and the markup tag.
摘要:
A nanoplasmonic resonator (NPR) comprising a metallic nanodisk with alternating shielding layer(s), having a tagged biomolecule conjugated or tethered to the surface of the nanoplasmonic resonator for highly sensitive measurement of enzymatic activity. NPRs enhance Raman signals in a highly reproducible manner, enabling fast detection of protease and enzyme activity, such as Prostate Specific Antigen (paPSA), in real-time, at picomolar sensitivity levels. Experiments on extracellular fluid (ECF) from paPSA-positive cells demonstrate specific detection in a complex bio-fluid background in real-time single-step detection in very small sample volumes.
摘要:
An optical platform and system for the simultaneous stimulation, manipulation and probing of multiple living cells in complex biological systems. The apparatus utilizes a spatiotemporal light modulator to expose a sample to pinpoints of light at selected times and wavelengths in two or three dimensional space and then detect the responses. In one embodiment, a spatiotemporal light modulator is optically coupled to a variable wavelength light source, a lens system and a system control unit with sample response sensors, wherein sample responses are detected after exposure to patterns of light in real time. Light patterns can be modulated in response to sample responses.
