Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for improved image segmentation using hyperspectral imaging. In some implementations, a system obtains image data of a hyperspectral image, the image data comprising image data for each of multiple wavelength bands. The system accesses stored segmentation profile data for a particular object type that indicates a predetermined subset of the wavelength bands designated for segmenting different region types for images of an object of the particular object type. The system segments the image data into multiple regions using the predetermined subset of the wavelength bands specified in the stored segmentation profile data to segment the different region types. The system provides output data indicating the multiple regions and the respective region types of the multiple regions.

Abstract: Image data is obtained that indicates an extent to which one or more objects reflect, scatter, or absorb light at each of multiple wavelength bands, where the image data was collected while a conveyor belt was moving the object(s). The image data is preprocessed by performing an analysis across frequencies and/or performing an analysis across a representation of a spatial dimension. A set of feature values is generated using the image preprocessed image data. A machine-learning model generates an output using to the feature values. A prediction of an identity of a chemical in the one or more objects or a level of one or more chemicals in the object(s) is generated using the output. Data is output indicating the prediction of the identity of the chemical in the object(s) or the level of the one or more chemicals in at least one of the one or more objects.

Abstract: A method and a device for measuring a fluid flow characteristic of an ambient fluid and modifying fluid flow of the ambient fluid, the method including: applying a first voltage between a first electrode and a second electrode, the first voltage being sufficient to generate a plasma in the first space; applying a second voltage between the first electrode and a third electrode, the second voltage being sufficient to generate a plasma in the second space; measuring a first current between the first and second electrodes, and a second current between the first and third electrodes; determining a fluid flow characteristic of the ambient fluid; and applying a third voltage between the first and second electrodes, the third voltage being sufficient to generate a plasma in the first space sufficient to modify fluid flow of the ambient fluid in the first direction in the first space.

Abstract: Example methods and systems for adjusting the beam width of radio frequency (RF) signals for purposes of balloon-to-ground communication are described. One example method includes determining, based on respective locations of a plurality of balloons and areas covered by respective ground-facing communication beams of the balloons, a contiguous ground coverage area served by the plurality of balloons, where the communication beam of a balloon defines a corresponding individual coverage area within the ground coverage area, determining a change in position of at least one of the balloons, based on the change in position of the at least one balloon, determining an adjustment to a first of the individual coverage areas in an effort to maintain the contiguous ground coverage area after the change in position of at least one of the balloons, and adjusting a width of the ground-facing communication beam of the balloon corresponding to the first individual coverage area in order to make the determined adjustment to the first individual coverage area.

Abstract: Methods and apparatus are disclosed for passively steering an antenna disposed on a balloon in a balloon network. An example balloon involves: (a) an antenna and (b) a pressure-sensitive mechanism in mechanical communication with the antenna such that a change in the balloon's altitude causes at least an element of the antenna to rotate upward or downward, a separation distance between two or more radiating elements to increase or decrease, or a separation distance between the two or more radiating elements and a reflector to increase or decrease.

Abstract: Example methods and systems for using radio frequency (RF) signals with different beam widths for purposes of balloon-to-balloon communication are described. One example method includes determining a vertical angle between a first balloon and a second balloon, if the vertical angle is below a threshold angle, communicating with the second balloon using a narrow beam RF signal from a communication system of the first balloon, and if the vertical angle is not below the threshold angle, communicating with the second balloon using a wide beam RF signal from the communication system of the first balloon.
