  • Patent number: 11536663
    Abstract: A portable apparatus for analyzing a plant specimen. A housing assembly defines a sensing volume and controls entry of ambient light into the sensing volume when the housing is closed. A specimen support positions a plant specimen within the sensing volume whereby light emitted from at least one light emitter is incident upon the plant specimen. An image sensor senses light from the at least one light emitter that has been incident on the plant specimen. A processor analyzes data obtained from the light sensor to assess one or more properties of the plant specimen. There may be more than one light emitter, e.g., a halogen lamp and LED array, and the apparatus may acquire images under more than one lighting condition. The apparatus may include a mechanism for moving the plant specimen relative to the optical path to take images at multiple regions of interest on the specimen.

  • Patent number: 11490023
    Abstract: This disclosure is generally directed to mitigating light-emitting diode (LED) imaging artifacts in an imaging system of a vehicle. In an example embodiment, the imaging system includes a first camera that operates under control of a first pulse trigger sequence, and a second camera that operates under control of a second pulse trigger sequence. The second pulse trigger sequence has a temporal offset with respect to the first pulse trigger sequence. The first camera captures an image of a light source, such as a traffic light containing LEDs. This image may contain an LED imaging artifact indicating that the traffic light is off. The second camera also captures an image of the light source. The temporal offset of the second pulse trigger sequence may eliminate the LED imaging artifact in the second image. A controller may compare the two images and determine that the traffic light is actually on.
