  • Publication number: 20210356460
    Abstract: A method of assaying biological content of a sample, termed “microsphere-based binding assay”, using microspheres made of polystyrene or other materials to capture and detect in a sample one or more biomarkers that may be present in the biological sample. The method is able to measure various antibodies associated with infection or vaccine response. Microspheres can be coated with capture antigens and exposed to multiple sets of biomarkers. The biomarkers can be fluorescently active or fluorescently labeled. The method analyzes the fluorescent profile using scanning cytometry. Increased safety, reliability and efficiency is achieved over prior art methods.

  • Patent number: 10337672
    Abstract: In processes and systems utilizing a compressor to fill a vessel with gas, for example, in the filling of the fuel tank of a vehicle that operates on compressed natural gas (CNG), a number of advantages are realized by establishing independent control over the flow rate of gas discharged from the compressor, such as on the basis of the compressor discharge pressure, utilizing feedback from one or more gas pressure sensors. In representative embodiments, a detected or actual measured compressor discharge pressure can serve as a process variable, in a feedback control loop for regulating the output of the compressor.

  • Publication number: 20180117690
    Abstract: A method for producing diamond grits for use in a wafer slicing system includes adjusting an initial diamond size distribution until an intermediate diamond size distribution is generated. The intermediate diamond size distribution has a corresponding simulated penetration thickness value less than or equal a predetermined penetration thickness value, and penetration thickness is a parameter proportional to a depth of subsurface damage that would occur when slicing an ingot using a diamond coated wire having an associated diamond size distribution. The method may include adjusting the intermediate diamond size distribution until a final diamond size distribution is generated, wherein the final diamond size distribution has a maximum diamond grit size that is substantially equal to a predetermined maximum diamond grit size, and manufacturing the diamond coated wire such that the diamond coated wire has a plurality of diamond grits that fit the final diamond size distribution.
