Abstract:
A portable sensor for measuring a hydration level of an object in close physical proximity with the sensor includes a portable housing having a total volume of less than about 50 cm3. First circuitry disposed in the housing includes a thermal source, a controller electrically coupled to the thermal source, a temperature sensing element, and a processor coupled to the temperature sensing element. When the object is in close physical proximity with the sensor, the thermal source is energized by the controller with a signal having a known function of time. The object affects a time variation of a temperature of the thermal source, the temperature sensing element senses the affected time variation of the temperature of the thermal source, and the processor determines a hydration level of the object based on a characteristic of the affected time variation of the temperature of the thermal source.
Abstract:
A reader device includes a camera board, processing circuitry in communication with the camera board, and an interface in communication with the processing circuitry. The camera board is configured to capture image data associated with an output signal area of a biological chromatographic test strip. The processing circuitry is configured to determine, based on the image data captured by the camera board, a concentration of a target analyte in a test sample submitted via the biological chromatographic test strip. The interface is configured to output data indicative of the concentration of the target analyte determined by the processing circuitry.
Abstract:
The disclosure describes systems (2) of navigating a hazardous environment (8). The system includes personal protective equipment (PPE) (13) and computing device(s) (32) configured to process sensor data from the PPE (13), generate pose data of an agent (10) based on the processed sensor data, and track the pose data as the agent (10) moves through the hazardous environment (8). The PPE (13) may include an inertial measurement device to generate inertial data and a radar device to generate radar data for detecting a presence or arrangement of objects in a visually obscured environment (8). The PPE (13) may include a thermal image capture device to generate thermal image data for detecting and classifying thermal features of the hazardous environment (8). The PPE (13) may include one or more sensors to detect a fiducial marker (21) in a visually obscured environment (8) for identifying features in the visually obscured environment (8). In these ways, the systems (2) may more safely navigate the agent (10) through the hazardous environment (8).
Abstract:
Fluid sensing devices including a layer of fluid absorption and distribution material are provided. The layer includes a porous fibrous nonwoven matrix for absorbing fluid from the object to the first major surface of the layer and laterally distributing the absorbed fluid throughout the layer and to a second major surface of the layer opposite the first major surface. Hydration sensors are disposed on the second major surface of the layer to measure a hydration level.
Abstract:
A shoe (606) degradation sensor (1012, 608) assembly includes a first sensor (1002) disposed in or proximate to a material layer of a shoe (606) between a foot space and an outer surface of the shoe (606). The material layer changes in at least one physical property with degradation to the shoe (606), and the first sensor (1002) is configured to indicate the changing physical property of the material layer thereby indicating a degree of degradation to the shoe (606).
Abstract:
The present disclosure provides a configuration and technique of fabricating remote phosphor optics (such as lenses) for downconverting LEDs, replacing the prior art solid hemispherical lenses with a novel thin-shell hemispherical lens that can be used with a wide range of encapsulating materials, including low index materials such as air and methyl silicones. The present disclosure further provides a configuration and technique whereby the remote phosphor lenses can be used with an LED array.
Abstract:
The present invention is a method of coating uniformly shaped and sized articles. The method includes providing a reactor having an arrayed inner surface, positioning the articles within the reactor, and coating the articles.
Abstract:
A method of coating film in a roll. A film is wound into a roll with gaps between the layers of the film in the roll. A fluid is forced through the roll such that the fluid deposits a coating on at least one side of the film.
Abstract:
A curable composition comprises a siloxane compound and a tetraalkyl orthotitanate. The siloxane compound comprises m divalent units represented by the formula –SiH(R1)O–, n divalent units represented by the formula –Si(R1)(OR2)O–, and p divalent units represented by the formula –Si(R1)2O–, wherein each R1 independently represents an alkyl group having from 1 to four carbon atoms, each R2 independently represents H or an alkyl group having from 1 to four carbon atoms, m and n are integers greater than or equal to 1, and p is an integer greater than or equal to 0. An at least partially cured curable composition and composite articles including the same are also disclosed.
Abstract:
An apparatus comprising a mobile computing device (902) physically coupled to a lightbox (904). The apparatus includes camera hardware, processing circuitry in communication with the camera hardware, and an interface in communication with the processing circuitry. The camera hardware is configured to capture image data associated with an output signal area of a biological chromatographic test strip (410) inserted into a receiving slot of the lightbox.
