Abstract: The present subject matter relates to Nickel-free (Ni-free) sealing of anodized metal substrates. In an example mentation of the present subject matter, an anodized metal substrate is disposed with a first layer of a Ni-free sealing material over a surface of the anodized metal substrate. Further, a second layer of a second sealing material is disposed atop the first layer to sandwich the first layer of Ni-free sealing material between the surface of the anodized metal substrate and the second layer, to form a sealed metal substrate.

Abstract: In one example, a hinge assembly may include a first hinge member and a second hinge member. The first hinge member may include a first hinge base and a first hinge bracket pivotally connected to the first hinge base. The second hinge member may include a second hinge base and a second hinge bracket pivotally connected to the second hinge base. Further, the hinge assembly may include a hydraulic unit connected between the first hinge member and the second hinge member to provide synchronous movements between the first hinge bracket and the second hinge bracket.
