  • Patent number: 10344194
    Abstract: A thermally conductive silicone composition is shown and described herein. The thermally conductive silicone composition comprises (A) an ionically modified siloxane, and (B) a thermally conductive filler comprising a first filler and a second filler, where the first filler and/or the second filler comprises a plurality of filler types, the plurality of filler types differing from one another in terms of particle size and/or morphology. The ionically modified siloxane may function as a dispersing aid or wetter for efficient dispersion of thermal conducting organic and inorganic fillers to achieve high thermal conductivity.
    Type: Grant

  • Publication number: 20180120480
    Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.

  • Publication number: 20150142171
    Abstract: Disclosed are methods adapted to calibrate a robot gripper to a camera. The method includes providing a robot with a coupled moveable gripper, providing one or more cameras, providing a target scene having one or more fixed target points, moving the gripper and capturing images of the target scene at two or more imaging locations, recording positions in the gripper coordinate system for each of the imaging locations, recording images in a camera coordinate system, and processing the images and positions to determine a gripper-to-camera transformation between the gripper coordinate system and the camera coordinate system. The transformation may be accomplished by nonlinear least-squares minimization, such as the Levenberg-Marquardt method. Robot calibration apparatus for carrying out the method are disclosed, as are other aspects.
