  • Publication number: 20250111525
    Abstract: This disclosure provides systems, methods, and devices for image processing. In a first aspect, a method of image processing includes receiving first image data from a first camera of an image capture device, wherein the first camera is different from a second camera of the image capture device; determining a first portion of the first image data; transforming the first portion of the first image data with a first strength based on an alignment difference between the first camera and the second camera; transforming a second portion of the first image data with a second strength based on the alignment difference between the first camera and the second camera; and determining a first output image frame based on the first image data after transforming the first portion of the first image data and transforming the second portion of the first image data. Other aspects and features are also described.

  • Publication number: 20250113111
    Abstract: This disclosure provides systems, methods, and devices for image processing that support enhanced variable aperture (VA) camera operations. In a first aspect, a method of image processing includes determining first image statistics for first image data representing a first scene captured at a first aperture; and determining whether the first image data satisfies a first criteria. When the first image data satisfies the first criteria, the image processing includes determining an updated lens shading correction (LSC) corresponding to the first aperture based on the first image statistics and on a current LSC corresponding to the first aperture; and determining a first output image frame based on the updated LSC and the first image data. Other aspects and features are also claimed and described.

  • Publication number: 20240351005
    Abstract: Provided are a silicate modified manganese-based material and a preparation method and application thereof. The silicate modified manganese-based material has a nanoscale needle like structure, and is prepared from a solution containing a manganese source and a soluble silicate source through an oxidation-reduction reaction and then a hydrothermal reaction. The manganese source includes a divalent manganese source and a heptavalent manganese source, with Mn (II) and Mn (VII) in a molar ratio of 0.5-5.5 to 1. The present disclosure uses silicate to regulate manganese oxides, significantly reducing the particle size of the manganese-based material, generating manganese vacancies, and changing the surface manganese valence state. An advanced oxidation system formed by the silicate modified manganese-based material and an oxidant has high removal rate and reaction rate for various organic compounds.

  • Publication number: 20230321140
    Abstract: The present subject matter provides a series of multifunctional anti-inflammatory agents comprising tannic acid, Zn2+, and different amounts of gentamicin (TA-Zn-Gen NPs) to effectively improve sepsis treatment through five modes of anti-sepsis activity: (1) bound cfDNA with high affinity and inhibited cfDNA-induced activation of TLRs and nuclear factor kappa B (NF-?B) signaling; (2) inhibited activated macrophage-induced macrophage recruitment; (3) scavenged ROS and reduced ROS-induced DNA damage and cell death; (4) inhibited NO production induced by bacterial LPS; and (5) provided potent antibacterial activity.

  • Publication number: 20190335714
    Abstract: A sound generating pet toy is provided which includes two similarly configured pet toy components. Each pet toy component has an exterior housing and an electronics module. The electronics module includes and electronics circuit having d.c. batteries, a microprocessor which includes a wireless transceiver component, a timer, a speaker, a push button on/off switch, and a high sensitivity vibration switch sensor. The microprocessor is electrically coupled to and powered by the batteries. The microprocessors are programmed to emit a sound upon activation from a first pet toy components, and thereafter to switch the generation of the sound to the second pet toy component upon sensing movement of the first pet toy component, this switching occurring back and forth between the two pet toy components as long as movement is sensed.

  • Publication number: 20190037807
    Abstract: A toy a pet laser toy 100 includes a housing 101 having a front end 104 and a rear end 105 relative to the forward direction of travel. The toy has a right wheel 107 coupled to a right motor 110 and a left wheel 108 coupled to a left motor 111. The motors are independently controlled through a microprocessor 118. The toy 100 also includes a light source 126 mounted to the housing 101 at a downward angle with respect to the horizontal plane underlying the toy. With the angular mounting of the light source 126, the light produced by the light source 126 is projected upon the underlying support surface a short distance behind the rear end 105 of the toy 100.

  • Publication number: 20140034525
    Abstract: A package for an animal containment system is provided. The package contains a plurality of horizontal support tubes and a plurality of vertical support tubes. The tubes are dimensioned and configured to be joined together by hardware to form a framing for the animal containment system along with a framing for a gate. The packaging includes a plurality of removable fence tubes and a plurality of gate tubes. The fence tubes and gate tubes are configured to be slidably received within aligned openings along the horizontal support tubes. The packaging also includes a box which contains the components for the system. Within the box substantially all of the fence tubes and substantially all of the gate tubes are nested within selected horizontal support tubes and selected vertical support tubes. A method of packaging an animal containment system is also provided herein.
