Pulse counting coincidence correction based on count rate and measured live time
An approach for counting particles suspended in a flow of gas or liquid in instruments that direct the flow through an illuminated region.

After counting the number of pulses, and determining the measured live time that the signal is below the threshold value, an initial particle concentration is calculated, and the calculation corrected for coincidence by calculating an actual live time as a measured live time minus a constant multiplied by the number of distinctly counted pulses, where the constant has the units of time.

Cytometry system and method for processing one or more target cells from a plurality of label-free cells
The present disclosure provides methods and systems for ghost cytometry (GC), which may be used to produce an image of an object without using a spatially resolving detector. This may be used to perform image-free ultrafast fluorescence “imaging” cytometry, based on, for example, a single pixel detector. Spatial information obtained from the motion of cells relative to a patterned optical structure may be compressively converted into signals that arrive sequentially at a single pixel detector. Combinatorial use of the temporal waveform with the intensity distribution of the random or pseudo-random pattern may permit computational reconstruction of cell morphology. Machine learning methods may be applied directly to the compressed waveforms without image reconstruction to enable efficient image-free morphology-based cytometry. Image-free GC may achieve accurate and high throughput cell classification as well as selective sorting based on cell morphology without a specific biomarker, which have been challenging using conventional flow cytometers. |

The venturi through passage includes a venturi nozzle insert that reduces the pressure of the working fluid to cause the liquid water in the working fluid to flash and restrict the flow of steam through the passage. The condensate nozzle is located in a reduced pressure discharge chamber into which a nozzle outlet discharges water condensate extracted by the nozzle and emptied from a trap outlet. The reduced pressure discharge chamber has an access opening sealed by a removable cover to allow the nozzle cartridge to be removed and replaced if necessary, without removing the steam trap from the process line. Locating the removable nozzle cartridge in a lower pressure region of the steam trap overcomes rating limitations on prior steam traps with replaceable venturi nozzles. |

There are two embodiments of the ABJB: 1. A basic ABJB 2. A smart ABJB The basic ABJB reacts to any distortion of the protected beam joint and applies a counter force to the two beams in than joint.The smart ABJB is also able to forecast some of the remaining wave forces in an earthquakes duration (from the first wave forms) and proactively apply counter forces (i.e. a Rayleigh Wave). It may also adjust the frequency, magnitude and direction in combination with the other ABJB's in the structure based on the properties of the external force on the structure.Additional sensors, such as strain gauges, wind speed sensors, wind direction sensors and accelerometers can be used to gather more data about any distortion of the beam structure which can then be utilized with an intelligent algorithm to forecast and proactively resist the beam structure from distorting due to external forces. |

The invention relates to a device for hydroentangling and/or structuring webs that includes an suctioning rotating drum and a structured shell, including at least two rings which can be pushed on and attached to the drum, is disposed at a distance from the cylindrical surface of the drum around. A web can be at least partially looped around the structured shell. At least one water bar including a nozzle strip with a plurality of nozzles is arranged relative to the structured shell to entangle and/or to structure and/or to perforate the web by the water jets. The invention further relates to the structured shell. |

Single-layer ceramic-based knit fabric for high temperature bulb seals
Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection. |

Upper for an article of footwear with a cuff
In one aspect, an upper for an article of footwear may include a knit element, a collar area configured to form an ankle opening, and a cuff in the collar area. The cuff may be at least partially formed by the knit element and may include a ribbed knit structure of the knit element. In another aspect, an upper for an article of footwear may include a knit element with a first area, the first area including a first side and a second side opposite the first side. The first side may be formed of at least 30% more material than the second side such that the first area is configured to curve convexly away from the first side. |

Webbing construction
The webbing construction absorbs stress and pressures on the edge of the webbing. The webbing locks into various hardware or an adjustment bar along the length of the webbing, such as every 1/32″ for slippage control of the webbing. The webbing of the present invention reduces the memory of folds made over a long period of time with a long shelf life. The webbing construction of the present invention can be used in a wide array of applications, such as for clothing belts, seat belt webbing, watch bands, backpacks, straps and the like. As a result, the webbing of the present invention addresses the shortcomings of the prior art to provide a superior webbing construction. |

Method of making a multi-composition fiber
A method of making a multi-composition fiber is provided, which includes providing a precursor laden environment, and forming a fiber in the precursor laden environment using laser heating. The precursor laden environment includes a primary precursor material and an elemental precursor material. The formed fiber includes a primary fiber material and an elemental additive material, where the elemental additive material has too large an atom size to fit within a single crystalline domain within a crystalline structure of the fiber, and is deposited on grain boundaries between adjacent crystalline domains of the primary fiber material to present an energy barrier to atomic diffusion through the grain boundaries, and to increase creep resistance by slowing down growth between the adjacent crystalline domains of the primary fiber material. |

Infrared reflecting fiber and fabricating method thereof
An infrared reflecting fiber includes 76.0 parts by weight to 88.5 parts by weight of a carrier, 1.8 parts by weight to 4.0 parts by weight of an infrared reflecting composition, 2.5 parts by weight to 7.5 parts by weight of a titanium dioxide containing composition, and 6.0 parts by weight to 16.0 parts by weight of a color adjusting composition. The carrier includes polyethylene terephthalate (PET). When a content of 5.0 wt % to 7.5 wt % of the infrared reflecting composition and a balance of the carrier are mixed together to form a first fiber, a maximum infrared reflectivity of the first fiber is between 61% and 70%. |
