Patent number: 10240910Abstract: Systems and methods for compressive image sensor techniques based on sparse measurement matrices are disclosed. A method to perform compressive sensing (CS) measurement operations for image sensors limits pixel summation to be within neighboring pixels and hence dramatically simplifies CS image sensor circuits and reduces their power consumption while providing better image quality compared to conventional random measurement matrix based methods. A sparse measurement matrix is applied to pixel data to generate a desired number of summation groups, each summation group consisting of outputs from an equal number of pixel cells. Each pair of summation groups contains the same number of shared outputs from pixel cells. From the summation groups, an image captured by the pixel cells is recovered.Type: GrantFiled: September 7, 2017Date of Patent: March 26, 2019Assignee: Board of Trustees of Southern Illinois University on Behalf of Southern Illinois University CarbondaleInventors: Stefan Leitner, Haibo Wang, Spyros Tragoudas

Publication number: 20130146221Abstract: Some embodiments of the invention include a method for preparing a carbon-containing membrane. The method includes preparing a carbon-containing solution and then washing and filtering the carbon-containing solution. The method further provides adding a volume of the washed and filtered carbon-containing solution to a receptacle that includes an aqueous solution. After a predetermined amount of time, the carbon-containing solution will equilibrate and form sheets of carbon-containing materials that float on a surface of the aqueous solution. The method further includes defining an aperture through at least a portion of a substrate and then inserting the substrate in the receptacle so that at least a portion of the carbon-containing sheets adhere to the substrate. In addition, the method further includes thermally treating the membrane to improve its molecular impermeability.Type: ApplicationFiled: December 13, 2012Publication date: June 13, 2013Applicant: Southern Illinois University CarbondaleInventors: Andrei Kolmakov, Dmitry Dikin, Sebastian Gunther, Jiaxing Huang

Patent number: 8383887Abstract: Disclosed are new effects of increased gdhA gene expression on plants that are susceptible to Aspergillus and Fusarium virguliforme infection. Plants transformed with the gdhA gene are resistant to aflatoxin accumulation following Aspergillus infection, and to root rot following F. virguliforme infection. The resistance to aflatoxin accumulation and root rot in gdhA+ plants is coincident with drought tolerance and resistance of the plants to certain herbicides. Methods for controlling aflatoxin contamination and root rot in crop plants, and for screening plants putatively transformed with gdhA, are described.Type: GrantFiled: February 18, 2010Date of Patent: February 26, 2013Assignee: Southern Illinois University CarbondaleInventors: Ahmad M.
