  • Publication number: 20240101725
    Abstract: A method of independently changing a melt rheology property value of a bimodal polyethylene polymer being made using a bimodal catalyst system in a single gas phase polymerization reactor. The method comprises process conditions comprising alkane(s) in the reactor. The method comprises a bimodal catalyst system that is characterized by an inverse response to alkane(s) concentration. The method comprises changing concentration of the alkane(s) in the reactor by an amount sufficient to effect a measurable change in the melt rheology property value; wherein the bimodal catalyst system is characterized by an inverse response to alkane(s) concentration such that when the alkane(s) concentration is increased, the melt rheology property value of the resulting bimodal polyethylene polymer is decreased, and when the alkane(s) concentration is decreased, the melt rheology property value of the resulting bimodal polyethylene polymer is increased.

  • Patent number: 10803275
    Abstract: A method for deconvolution of digital images includes obtaining a degraded image from a digital sensor, a processor accepting output from the digital sensor and recognizing a distorted element within the image. The distorted element is compared with a true shape of the element to produce a degrading function. The degrading function is deconvolved from at least a portion of the image to improve image quality of the image. A method of indirectly decoding a barcode includes obtaining an image of a barcode using an optical sensor in a mobile computing device, the image comprising barcode marks and a textual character. The textual character is optically recognized and an image degrading characteristic is identified from the textual character. Compensating for the image degrading characteristic renders previously undecodable barcode marks decodable. A system for deconvolution of digital images is also included.

  • Patent number: 9182340
    Abstract: An optical measuring apparatus comprising at least one light emitting unit, a stage, at least one lens, and at least one light detector is provided. The light emitting unit emits a light beam. The stage contains accommodating spaces. The accommodating spaces move to the transmission path of the light beam in turn. The lens is located between the light emitting unit and the stage, whose orthogonal projection on the stage appears substantially to be a polygon. When one of the accommodating spaces moves to the transmission path of the light beam, a perpendicular bisector half line of each side of the polygon is not overlapped with another adjacent accommodating space of the accommodating spaces. An optical measuring method is also provided.
