Abstract: Button functionalities for user interfaces, e.g., for use with a portable multifunction device, are disclosed. Exemplary button functionalities are described for an electronic device with a display, a rotatable and depressible input mechanism, and/or a button. Different device features may be accessed, depending on whether the rotatable and depressible input mechanism or the button is activated, and further depending on whether the activation represents a single press, a double press, or an extended press on the rotatable and depressible input mechanism or the button.

Abstract: A system may have a support structure that separates an exterior region from an interior region. The system may include a lighting system with interior and/or exterior lights with adjustable diffusers. An interior light may be used as a task light, a cabin light, a sensor indicator light, or a trim light. Adjustments to the adjustable diffusers can be used to adjust the angular spread of emitted light for operation in different lighting modes.

Abstract: A process is provided for fabricating composite membranes by coating a porous substrate with a solution of selective polymer. A reserve of non-solvent medium is incorporated in the substrate pore network which allows the substrate to be successfully coated with a polymer solution formulated in a solvent medium which is also a solvent for the substrate material.

Abstract: Asymmetric polyacetylene polymer membranes having both improved selectivity and improved flux are provided by a process which comprises forming a solution containing from about 1 to about 5% by weight of a polyacetylene polymer in any suitable solvent therefor, forming the solution into a thin film and quenching the film in an aqueous bath in the presence of from about 0.002 to about 0.4% by weight of the quench bath of surfactant with an HLB value of 11 to 15. Additionally, the polyacetylene polymer solution contains a swelling agent at about 1% to about 10% by weight of polyacetylene polymer solution.

Abstract: Anisotropic gas separation membranes are treated to alter the microporosity of their thin, dense layer or composite coating--the layer or coating which provides selectivity in separations employing such membranes. The treatment increases the selectivity of a membrane with minimal decrease in its flux. The process comprises applying a polar activator to the membrane followed by exposing the membrane to microwave frequency radiation for a period of time sufficient to compact the thin layer of the membrane. The polar activator may be incorporated in the membrane during fabrication or applied as an after-treatment.
