Patent number: 9146173Abstract: The reusable energy absorbing lab seat 10 includes a seat bucket for holding an anthropomorphic test device, a seat support structure, an energy absorbing system, a false floor structure, and a fail-safe system. The seat support structure is for securing the seat bucket to a sled that corresponds to a horizontal accelerator. The energy absorbing system is for absorbing energy imposed by the horizontal accelerator on the seat bucket and the anthropomorphic test device. The false floor structure is for simulating a real floor of a vehicle or aircraft. The fail-safe system is for reducing damage to the reusable energy absorbing seat, the anthropomorphic test device, and lab facilities in case the energy absorbing system fails.Type: GrantFiled: February 12, 2014Date of Patent: September 29, 2015Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael Knott, Brandon Hall, Zachary Cass

Patent number: 8997021Abstract: According to various embodiments of the invention, parallax and/or three-dimensional effects are added to thumbnail image displays. In at least one embodiment, such effects are applied in a manner that causes the thumbnail images to appear to respond to their display environment. For example, a parallax effect can be applied that responds to current cursor position, scroll position, scroll velocity, orientation of the display device (detected, for example, by position- and/or motion-sensing mechanisms), and/or any other environmental conditions. As another example, thumbnail images can be refocused, and/or a viewpoint for an image can be adjusted, in response to a user clicking on or tapping on particular elements within such images.Type: GrantFiled: November 6, 2012Date of Patent: March 31, 2015Assignee: Lytro, Inc.Inventors: Chia-Kai Liang, Michael Knott, Mugur Marculescu, Jason Wilson, Yi-Ren Ng

Patent number: 8367013Abstract: An optical reflectance kit including a reading device and membrane test strip is disclosed for conducting a lateral flow assay. The reading device is portable. Assays may be conducted on bodily fluids to detect with high sensitivity the presence of certain hormones, glucose, or other bodily fluids of interest. Membrane test strips may receive a test fluid or test sample containing an analyte to be detected. The membrane test strips may be inserted directly into a receiving port of a reading device. Shielding stray light from the receiving port improves sensitivity and reduces the entry of stray or ambient light into the reading device. The reading device also includes one or more sensors capable of detecting the intensity of reflected electromagnetic radiation.Type: GrantFiled: December 24, 2001Date of Patent: February 5, 2013Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Rosann Kaylor, Difei Yang, Michael Knotts

Patent number: 7796266Abstract: A system that employs transmission-based detection techniques to determine the presence or concentration of an analyte within a test sample is provided. Specifically, the optical detection system contains a chromatographic-based assay device that is positioned in the electromagnetic radiation path defined between an illumination source and detector. To enhance the sensitivity and signal-to-noise ratio of the system without significantly increasing costs, the distance between the illumination source and/or detector and the assay device is minimized. The illumination source and/or detector may also be positioned directly adjacent to the assay device. In addition, the system may be selectively controlled to reduce reliance on external optical components, such as optical filters or diffusers.Type: GrantFiled: December 22, 2004Date of Patent: September 14, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: David Samuel Cohen, Xuedong Song, Michael Knotts, Shawn Ray Feaster, Zdravko Savov Atanassov

Publication number: 20090314946Abstract: A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes time-resolved fluorescence to detect the signals generated by excited fluorescent labels. Because the labels can have relatively long emission lifetime, short-lived background interference can be practically eliminated through delayed fluorescence detection. In addition, the resulting fluorescent reader can have a simple and inexpensive design. For instance, in one embodiment, the reader can utilize a silicon photodiode and a pulsed light-emitting diode (LED) to accurately excite labels and detect fluorescence on a membrane-based assay device without requiring the use of expensive components, such as monochromators or narrow emission band width optical filters.Type: ApplicationFiled: August 31, 2009Publication date: December 24, 2009Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Xuedong Song, Rosann Kaylor, Michael Knotts, Ning Wei

Publication number: 20070269725Abstract: A light control material is provided for displaying color images having microstructures either on its surface or within the material which reflect a selected color and bandwidth of light in accordance with their physical characteristics. In an exemplary embodiment, the microstructures are stepped structures which reflect a particular color and bandwidth of light in accordance with the height of the steps of the stepped structures. In alternative embodiment, the microstructures are ribbed structures or crystal like structures designed to reflect a selected color and bandwidth of light. In addition, methods of fabricating the material are provided.Type: ApplicationFiled: May 21, 2007Publication date: November 22, 2007Applicant: NANOVENTIONS, INC.Inventors: Richard Steenblik, Mark Hurt, Michael Knotts
