Patent number: 10501867Abstract: A self-aligned tunable metamaterial is formed as a wire mesh. Self-aligned channel grids are formed in layers in a silicon substrate using deep trench formation and a high-temperature anneal. Vertical wells at the channels may also be etched. This may result in a three-dimensional mesh grid of metal and other material. In another embodiment, metallic beads are deposited at each intersection of the mesh grid, the grid is encased in a rigid medium, and the mesh grid is removed to form an artificial nanocrystal.Type: GrantFiled: March 15, 2016Date of Patent: December 10, 2019Inventors: Arturo A Ayon, Ramakrishna Kotha, Diana Strickland

Publication number: 20180374975Abstract: Embodiments are directed to compositions comprising photoluminescent elements (e.g., quantum dots) that absorb UV radiation and emit longer wavelength non-ultraviolet radiation (luminescent down shifting), effectively sequestering the UV radiation. In certain aspects the photoluminescent elements are dispersed on or in a material. In a further aspect the material is transparent to light. In one respect the photoluminescent elements are dispersed in a transparent film.Type: ApplicationFiled: April 1, 2016Publication date: December 27, 2018Applicant: THE BOARD OF REGENTS OF THE UNIVERSITY OF TEXAS SYSTEMInventors: Arturo A.

Patent number: 9829396Abstract: A surface mounted monitoring system is disclosed that is useful for detecting the presence of both ordinary and excessive loads on a surface, and for providing real-time or near real-time trending data. The system includes an array of force transducers disposed on the exterior surface of a structural member such as a roof. In an exemplary embodiment, transducers may be placed on an interior surface, such as embedded within insulation. The force transducers detect the magnitude of a load force acting on the surface. A data analysis module (DAM) may record force readings in a circular memory buffer, so that recent data can be recovered in the event of a catastrophic collapse. The DAM may also communicate with a monitoring device that can display real-time loading data to a user and perform other analysis.Type: GrantFiled: April 22, 2011Date of Patent: November 28, 2017Assignee: BOARD OF REGENTS OF THE UNIVERSITY OF TEXAS SYSTEMInventors: Arturo Ayon, Cory Hallam

Patent number: 9714875Abstract: Various systems and techniques may be used to enhance the sensing loads on a roof surface. In some implementations, an impact-resistant surface-mounted roof sensor system may include a sensor, a protective cover, and a load transfer mechanism. The sensor may be adapted to sense a load incident thereon, and the protective cover may be configured to span at least the width of the sensor and adapted to withstand impacts from dense media and an direct incident load. The load transfer mechanism may be adapted to mechanically transfer a load applied on the protective cover to the sensor.Type: GrantFiled: September 19, 2012Date of Patent: July 25, 2017Inventors: Arturo A. Ayon, Cory Hallam, Dylan Ginn

Patent number: 8502679Abstract: A non-invasive motion and respiration monitor receives impulses from a subject's movement, heartbeat, and respiration. The raw signal is biased and digitized, and a signal processor applies a Fast Fourier Transform to the signal. The transformed signal is filtered to isolate the component representing heart rate from the component representing respiration. An Inverse Fast Fourier Transform is then applied to the component signals, which are sent to a processor. The processor is programmed to detect irregularities in the respiration and heart rate. If severe irregularities or complete cessation is detected in either signal, a mechanical stimulator is actuated to try to stimulate the subject, and an alarm is sounded to alert a caregiver such as a parent or nurse.Type: GrantFiled: October 8, 2009Date of Patent: August 6, 2013Assignee: The Board of Regents of the University of Texas SystemInventors: Arturo A. Ayon, Christopher Berg, David C. Valdez

Patent number: 6399516Abstract: Provided is a method for producing a silicon element. A substrate configuration is provided that includes a silicon layer having a first face and a thickness corresponding to a specified thickness of the silicon element to be formed. The configuration includes a layer of an electrically-insulating material located below and adjacent to the silicon layer. A substantially vertical trench is etched from the first face in the silicon layer to a depth that exposes the insulating layer. Then the trench in the silicon layer is exposed to a gaseous environment that is reactive with silicon, to substantially lateral etch the silicon layer preferentially at the depth of the insulating layer along a surface of the insulating layer. This lateral etch is continued for a duration that results in release of a silicon element over the insulating layer. Also provided is a process for etching an angled trench in a silicon layer.Type: GrantFiled: October 29, 1999Date of Patent: June 4, 2002Assignee: Massachusetts Institute of TechnologyInventor: Arturo A.
