  • Patent number: 11552324
    Abstract: A flow battery system and methods are provided for eliminating crossover issues of active materials in redox flow batteries. A solid adsorbent with large specific surface area is disposed in an electrolyte of at least one half-cell, in contact with the electrolyte. During a charging process, the active material in a charged state is captured and stored on surfaces of the adsorbent, so that concentrations of the active material in the electrolyte in the charged state is reduced and the crossover is inhibited. During a discharging process, the active material is desorbed from the adsorbent to the electrolyte and pumped into the stack for reaction. The flow battery stack can have a microporous membrane separator. The electrolyte of the flow battery includes zinc iodide as active material and polyethylene glycol (PEG) as an additive.

  • Publication number: 20220414847
    Abstract: Systems and techniques are described for generating a high dynamic range (HDR) image. An imaging system can be configured to receive a first image captured by an image sensor according to a first exposure time. The imaging system can generate a modified image based on the first image by modifying the first image using a gain setting to simulate a second exposure time based on exposure compensation. The imaging system generates a high dynamic range (HDR) image at least in part by merging multiple images. The multiple images include a second-exposure image that corresponds to the second exposure time. The second-exposure image can be the modified image. The second-exposure image can be based on the modified image, processed variant of the modified image processed for noise reduction based on one or more other images actually captured using the second exposure time.

  • Patent number: 11373281
    Abstract: Methods, systems, and devices for anchor frame switching in an imaging system are described. A device may generate a pixel map based on a set of frames. A first subset of frames of the set of frames have a first exposure and a second subset of frames of the set of frames have a second exposure different than the first exposure. The device may determine a region of the pixel map representing motion between at least two frames of the first set of frames. If the device determines that a quantity of motion pixels in the region is higher than a threshold, the device may select a short exposure frame as an anchor frame, beginning at a later frame. Otherwise, the device may maintain using a long exposure frame as the anchor frame.
