  • Patent number: 9415561
    Abstract: Multilayered polymer films are configured so that successive layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets. The layer packets are individually peelable from the remainder of the film. Combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packet pairs. The films are post-formed, e.g. using heat and pressure, to deform the film from an initial flat or limp condition into a contoured shape that is self-supporting. The contoured shape may comprise regions of simple and/or complex curvature. Despite the permanent contoured shape, individual packets can still be successively peeled away to expose a fresh surface of the next layer packet, having the same contoured shape.

  • Publication number: 20160223731
    Abstract: A multilayer optical film (130) has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film Heating elements (122) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered regions of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered regions to pattern the film The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g.

  • Publication number: 20160209558
    Abstract: The present application generally relates to retroreflective articles and methods of making retroreflective articles. The retroreflective articles include a substantially amorphous polymeric layer between the body layer and the discrete truncated cube corner elements. The substantially amorphous polymeric layer absorbs, dissipates, and/or accommodates at least some of the stress forces placed on the retroreflective article during processing. As a result, discrete truncated cube corner elements with increased fidelity can be formed.

  • Publication number: 20160205437
    Abstract: Methods and apparatus for smoothly and efficiently upgrading set top boxes, e.g., personal video recorders, which have customer selected content stored thereon are described. The described methods allow content stored on a set top box to be uploaded to a network storage device, e.g., automatically at a predetermined time prior to a scheduled upgrade, or in some cases, via manual control of the set top box to be upgraded. After stored content is uploaded to the network storage device, the set top box is replaced with a new set top box. The new set top box can be preloaded with the previously uploaded content or a content download can be triggered, e.g., by activating a hidden application and by supplying information identifying the set top box being replaced as part of the upgrade process.

  • Patent number: 9366607
    Abstract: In a first mode, a monitoring system inputs humidified gas through at least a portion of a conduit. At least a portion of the water in the humidified gas adheres to the inner surface of the conduit, inhibiting contaminants in the gas sample from adhering to the inner surface. The water in the humidified gas may also push any contaminants adhered to the surface of the sample line back out the sample line. In a second mode, after previously passing the humidified gas through the conduit, the monitoring system controls a flow of a gas sample including the contaminants through the conduit to a gas analyzer. The one or more layer of water on the inner surface of the conduit prevents or reduces a buildup of undesirable contaminants on an inner surface of a conduit that conveys gas samples.

  • Publication number: 20160151061
    Abstract: Devices and systems for use in soft tissue repair are provided, as are methods of manufacturing the same. In one exemplary embodiment, an implantable surgical construct includes an implant and a continuous braided closed filament loop that is attached to the implant. The continuous loop can be formed from a single strand of filament such that portions of the filament, sometimes referred to as tails, can be arranged with respect to each other to form a braided configuration. A related method of manufacture can involve passing portions of a single strand of filament around different sets of posts and selectively over and under each other to create the braided configuration. Other devices, systems, and methods of manufacturing are also provided, including some that involve using multiple strands of suture to form a continuous braided closed filament loop.

  • Publication number: 20160089858
    Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packets pairs. Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.
