  • Publication number: 20020198730
    Abstract: A method for recovering carpet comprising polymeric fibers. A seller, i.e. retailer, manufacturer or distributor installs a carpet at a consumer location and establishes and maintains a database of installed carpet information comprising carpet type, installation date and consumer identification data. The useful lifetime of the installed carpet is estimated, and the seller contacts the consumer within a determined period of time of the end of the estimated useful lifetime of the carpet. The seller then preferably provides the consumer with an incentive to replace the carpet, such as a credit towards the purchase of a replacement carpet from the seller. The seller then collects the used carpet and sorts the collected carpet according to polymeric fiber type. At least one type of polymeric fiber is converted into a recovered polymer composition, such as by depolymerizing it into its monomeric components and then repolymerizing the monomeric components to form a recovered polymer composition.

  • Patent number: 6351375
    Abstract: Method and apparatus is described herein for accommodating two types of hard disks, for example, SCSI disks and FC-AL disks, using a single, dual-purpose backplane. The dual-purpose backplane includes a plurality of drive bays each including a first connector for receiving a complementary connector of an SCSI disk and a second connector for receiving a complementary connector of an FC-AL disk. In a computer system, one or the other of the first and second connectors is mounted upside down to avoid overlapping and structural interference with connection of other hard disks to the backplane. In an external storage system, hard disks are inserted sideways, and thus one connector type is mounted on the backplane in an orientation rotated 180 degrees from the other connector type.

  • Patent number: 5572572
    Abstract: A telephone configures as a programmable microcomputer (telephone-computer) which operates in most circumstances through a standard telephone 12-key keypad input. The telephone-computer has the overall appearance of a telephone and includes telephone electronics and a microprocessor unit operated in conjunction with other computer elements, including memory devices, a programmable gate array (PGA) chip which can be initially programmed and then fixed, and enhanced integrity features. The PGA has the capability of being configured to accommodate various types of software which require different hardware Configuration, but without actually reconfiguring the hardware. The telephone-computer delivers data processing capabilities and services through an ordinary telephone instrument via conventional telephone lines with a network host computer which communicates with a vast panoply of service bureaus.
