  • Patent number: 10634794
    Abstract: The present disclosure is directed to an obstacle awareness device for vehicle systems. A threshold distance is set that identifies the range at which an obstruction interferes with fluid dynamics around and through at least one propulsion motor. One or more ranging sensors on the vehicle system detect relative position information of the obstruction when it is within the threshold distance. The relative position information is communicated to a controller, which adjusts a motor control signal to compensate for the obstruction interfering with the fluid dynamics around the at least one propulsion motor. The threshold distance may be defined by a three dimensional shape that encapsulated the vehicle system 100, and the three dimensional shape may change in shape or size with movement of the vehicle system.

  • Patent number: 9651724
    Abstract: Disclosed are embodiments of photo-luminescent display systems and photo-luminescent visual elements creating eye-catching displays of visual advertising or marketing messages that are very effective at generating interest, engagement, and loyalty in the viewing public. Photo-luminescent pigment containing visual elements are illuminated by one or more remotely located emitters at a first wavelength that is outside the human visual spectrum. In response, the visual elements then radiate at one or more wavelengths within the human visual spectrum. Additional features control unwanted reflections and unwanted transmission of radiation at the first wavelength. Additional features control the uniformity of radiation of one or more wavelengths within the human visual spectrum.

  • Patent number: 9594053
    Abstract: A system and method for generating a digital image in fluorescence gel imaging is disclosed. The method includes providing a gel sample and placing the gel sample on a flat panel detector having array of photodiodes and transistors that collect light generated from the gel sample. The gel sample is illuminated using a light source integrated into the flat panel imaging system and light emitted by the gel sample responsive to an excitation of the gel sample by light provided by the light source is then collected, with the light emitted by the gel sample being collected by the array of photodiodes of the flat panel detector and converted to electric charges to generate light data. The light data is then processed to generate a digital image of the gel sample.

    Abstract: Reagents, assays, methods, kits, devices, and systems for rapid measurement of cholesterol and cholesterol sub-fractions from a blood sample are provided. Total cholesterol, low density lipoprotein cholesterol, and high density lipoprotein cholesterol can be measured in a single assay using kinetic measurements, under conditions in which cholesterol sub-species are converted to a detectable product at distinct rates. The detectable product is measured at different times after assay initiation. A lipase, cholesterol esterase, cholesterol oxidase and a peroxidase may be used together to produce colored product in amounts directly proportional to the quantity of cholesterol converted. Methods for calculating very-low density lipoprotein cholesterol levels by further including triglyceride measurements are disclosed.
