  • Publication number: 20230302761
    Abstract: A composition may comprise a fabric substrate having a first melting temperature and a polymer sheet having a second melting temperature, wherein the second melting temperature may be less than the first melting temperature. The polymer sheet and the fabric substrate may have a base thermoplastic polymer in common. The polymer sheet may be at least partially melted and laminated onto the fabric substrate such that the polymer sheet and fabric substrate become fused to produce a fused laminated fabric. A recycling process may be performed on the fused laminated fabric, wherein the fabric substrate and the polymer sheet remain laminated throughout the recycling process.

  • Patent number: 11051137
    Abstract: A method and system for distributed messaging between a plurality of computer devices using a short range wireless communication protocol (SRWP) is disclosed. The communication protocol can be one in which slave devices provide data to master devices. A device automatically establishes master and slave connections with other devices via the protocol as they come into range. A user-entered message is displayed on the device and broadcast by the device over slave connections to other connected devices. Messages received by the device over its master connections are displayed and also rebroadcast to other connected devices. Messages can be displayed for a limited time period during which they fade or otherwise are altered to provide a visual indication of the display lifetime remaining for that message. A relay can be provided to receive an rebroadcast messages to connected devices and inject into the SRWP network from devices outside the network.

  • Patent number: 8850786
    Abstract: Intermittently colored yarns having an intermittent and random dye spacing pattern, and systems and methods of making the same, are disclosed. Such intermittently colored yarns exhibit higher quality and lower manufacturing costs over the known intermittently colored yarns. The intermittent coloring takes place while the yarn is in caterpillar form. Carpets made from such intermittently colored yarns exhibit enhanced aesthetics over carpets made from known intermittently colored yarns. Alternatively, a stain resist, colorless base dye, or bleaching agent can be applied in the same intermittent and random spacing pattern to the intermittently colored yarns prior to subsequent dyeing. This creates a mirror image like color effect to the resulting yarn.
