  • Publication number: 20190113447
    Abstract: A method includes decomposing a training set to obtain a principal component matrix having a plurality of principal component vectors. The method also includes variably rejecting portions of a sample spectrum vector that do not correspond to a selected one of the plurality of principal component vectors by incrementally providing a coefficient indicative of the weighting of the selected principal component vector for selected sub-regions. A corrected spectrum vector can be obtained by excluding certain sub-regions of the sample spectrum vector and corresponding principal component vector, multiplying the sample spectrum vector with the principal component matrix for non-excluded sub-regions, providing a predicted interference vector, and subtracting the predicted interference vector from the sample spectrum vector.

  • Patent number: 10259915
    Abstract: The present invention relates to substrates comprising a crosslinked network of covalently attached antimicrobial and/or antibiofouling polymers. The crosslinked network of antimicrobial and/or antibiofouling polymers acts highly efficiently against pathogens, e.g. bacteria and fungi. Both the antimicrobial and the antibiofouling cross-linked polymer networks are preferably better resistant to mechanical damage than simple surface-immobilized polymer monolayers. The antimicrobial and/or antibiofouling polymers of the crosslinked network are preferably obtained by ring opening metathesis polymerization (ROMP) and exhibit a molecular weight of preferably more than 30,000 or even 100,000 g mol?1. The crosslinked network of antimicrobial and/or antibiofouling polymers is preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc.

  • Publication number: 20180322399
    Abstract: A device may receive training spectral data associated with a manufacturing process that transitions from an unsteady state to a steady state. The device may generate, based on the training spectral data, a plurality of iterations of a support vector machine (SVM) classification model. The device may determine, based on the plurality of iterations of the SVM classification model, a plurality of predicted transition times associated with the manufacturing process. A predicted transition time, of the plurality of predicted transition times, may identify a time, during the manufacturing process, that a corresponding iteration of the SVM classification model predicts that the manufacturing process transitioned from the unsteady state to the steady state. The device may generate, based on the plurality of predicted transition times, a final SVM classification model associated with determining whether the manufacturing process has reached the steady state.

  • Publication number: 20180231000
    Abstract: Disclosed is a compressor, including a crankshaft (10), and a first cylinder (20), a second cylinder (30) and a third cylinder (40) arranged sequentially in an axial direction of the crankshaft (10). The first cylinder (20) is a high-pressure cylinder, and the second cylinder (30) and the third cylinder (40) are low-pressure cylinders. The compressor also comprises a capacity variation switching mechanism (50) for controlling loading and unloading of the third cylinder (40). The compressor has a full operation mode and a partial operation mode. By means of the capacity variation switching mechanism (50) provided in the compressor, at least one cylinder is allowed to be put into use or unloaded under the action of the capacity variation switching mechanism (50), thus enabling a capacity variation switching function of the compressor to meet operational requirements of different operating conditions.

  • Publication number: 20180125432
    Abstract: Differences of electromagnetic (EM) properties between healthy and cancerous tissues allow detection of abnormal conditions occurring in a tissue of an animal, for example, intra-operative cancer detection. By using a time-varying EM field, electrical eddy currents are generated in the tissue sample, and assessed using phase-sensitive detection. In some aspects, a change in phase shift between the voltage in a receiver coil and the voltage in a driver coil provide a direct and immediate indication of differences in EM properties of specimens.

For instance, a system includes a first electromagnetic radiation source configured to illuminate a sample with a first portion of electromagnetic radiation in a first region of the electromagnetic spectrum (e.g., an IR source) and a second electromagnetic radiation source configured to illuminate a sample with a second portion of electromagnetic radiation in a second substantially monochromatic region of the electromagnetic spectrum (e.g., a laser source). The system also includes a detector module configured to detect a sample constituent of a sample by analyzing a characteristic of electromagnetic radiation reflected from the sample associated with the first electromagnetic radiation source and a characteristic of electromagnetic radiation reflected from the sample associated with the second electromagnetic radiation source.
