10 Patents on Compressive Sensing Issued to InView Technology Corporation in 2014
Ten patents were issued to InView Technology Corporation in 2014 covering the implementation and improvement of its Compressive Sensing camera architecture and algorithms. With its initial product, the InView210™, InView has developed the world’s first SWIR camera based on the computational imaging architecture of compressive sensing. InView continues to enhance its IP portfolio of 12 issued patents and 10 additional patent applications surrounding the implementation of its unique imaging modality, whose mathematical foundations were developed only within the last decade. The foundational patent on the single-pixel camera architecture was issued in 2012 to Rice University and, along with other related patents, is exclusively licensed by InView.
Current development projects funded by DoD and NSF grants include a compressive video camera with high speed event detection capabilities. InView is also developing a multi-spectral camera that can create false-color images combining visible and near infrared wavebands.
InView continues to innovate its compressive sensing architecture and data acquisition strategies to take advantage of its unique computational platform and welcomes licensing and investment inquiries.
