  • Publication number: 20230047120
    Abstract: A portable data collection device includes a FT-NIR spectrometer operable with a direct current (DC) power input, a hand-held probe having a large sampling area, a portable computer operable with a DC power input and configured for operation of the FT-NIR spectrometer; and a portable electric power source for providing a DC power output. The components of the portable data collection device are contained within a portable carrier. The portable data collection device is used onsite to obtain a spectra from a material sample. The spectra is sent by the portable computer of the portable data collection device to a remote computer/server. Application methods stored in a remote database analyze the spectra to obtain desired trait results for the material sample. The obtained results are stored on a remote database and can be displayed on a screen of an on-site mobile device.

  • Patent number: 8241537
    Abstract: An electrospinning apparatus is described. The electrospinning apparatus has a rotary nozzle mechanism that moves simultaneously along a non-linear track for forming polymeric fibrils, so that the polymeric fibrils can be piled to form a uniform web on a receiving carrier from any receiving angle. Therefore, the electrospinning apparatus resolves problems of the prior polymeric fibrils, such as various distribution and slow production rate. In addition, a method of manufacturing polymeric fibrils in the aforementioned electrospinning apparatus is further described.

  • Patent number: 8010309
    Abstract: A method of analysis, analysis system, program product, apparatus, and method of supplying analysis of value incorporating the use of at least one data acquisition device, a central processor, and a communication link that is connectable between the data acquisition device and the central processor. The central processor is loaded with multivariate calibration models developed for predicting values for various properties of interest, wherein the calibration models are capable of compensating for variations in an effectively comprehensive set of measurement conditions and secondary material characteristics. As so configured, the calibration models can compensate for instrument variance without instrument-specific calibration transfer. Measurement results generated by the central processor can be transmitted to an output device of a user interface.

    Abstract: A fabric membrane texture and manufacturing method thereof explores a texture of fabric membrane comprising of 3D fabric. An upper and a lower fiber texture layers of the 3D fabric membrane are stretched to build up an air sandwich through plural middle connecting fibers. The 3D fabric enables to execute the functions of anti-bump, thermal insulating, thermal conductivity, air permeability and elastic strength. Additionally, a polymer membrane is used to adhere to at least one of the 3D fabric to build up a better function of shielding, insulating, or the capacity of ambiance impedance. Besides, this polymer membrane adheres to the 3D fabric using the process of low-pressure fixation that is applied to the product enables to obtain the better distance of spacer.
