Patent number: 11375595Abstract: An approach for controlling ultraviolet intensity over a surface of a light sensitive object is described. Aspects involve using ultraviolet radiation with a wavelength range that includes ultraviolet-A and ultraviolet-B radiation to irradiate the surface. Light sensors measure light intensity at the surface, wherein each sensor measures light intensity in a wavelength range that corresponds to a wavelength range emitted from at least one of the sources. A controller controls the light intensity over the surface by adjusting the power of the sources as a function of the light intensity measurements. The controller uses the light intensity measurements to determine whether each source is illuminating the surface with an intensity that is within an acceptable variation with a predetermined intensity value targeted for the surface. The controller adjusts the power of the sources as a function of the variation to ensure an optimal distribution of light intensity over the surface.Type: GrantFiled: October 7, 2019Date of Patent: June 28, 2022Assignee: Sensor Electronic Technology, Inc.Inventors: Arthur Peter Barber, Maxim S.

Patent number: 11344230Abstract: Embodiments of the invention disclosed herein are directed to articles of clothing that allow for monitoring of different analytes (e.g., electrolytes and molecules) in human sweat during fitness activity, while training, or simply in everyday life. The clothing includes a sensor system completely integrated in textile such that every sensing part is made of textile fibers. The clothing is able to control, collect, analyze, and expel the sweat over time. The textile sensor allows a spontaneous absorption of body sweat directly from the skin, while it is produced, using the hydrophilic natural properties of the textile. Then, once adsorbed, the flux of sweat is controlled and guided through the textile using a gradient of the textile's hydrophilic properties. The sweat guided through the textile is analyzed through an electrochemical sensor woven into the textile. Finally, the sweat is collected in a reservoir and expelled for evaporation.Type: GrantFiled: April 2, 2018Date of Patent: May 31, 2022Assignee: HFT Smart Sensors, IncorporatedInventors: Nicola Coppedè, Andrea Zappettini
