A new architecture capable of utilizing the existing twisted pair interface between customer premises equipment and an associated serving local switching office is used to provide a vast array of new services to customers. Using an intelligent services director (ISD) at the customer services equipment as an interface for the equipment to an existing twisted cable pair and a facilities management platform (FMP) at the serving local switching office as an interface to various networks and service opportunities, new services such as simultaneous, multiple calls (voice analog or digital), facsimile, Internet traffic and other data can be transmitted and received over the twisted cable pair by using digital subscriber loop transmission schemes. The new services include but are not limited to videophone, utility meter reading and monitoring, broadcasting and multicasting. The architecture provides for fault-tolerant, transparent interaction of components and services and supports a variety of standards for each level of the open systems interconnection layers and layers of TCP/IP. The FMP connects electronically or optically to the public switched telephone network, Internet backbone, a private Intranet as well as other possible network connections.

We make particulates, especially magnetic Fe—Co alloys having high magnetic permeability, of controlled dimensions, especially those having a narrow thickness size distribution centered around a median or target thickness in the range of about 0.1-1.0 μm, using electrodeposition typically on a smooth (polished) titanium cathode. Our preferred continuous process uses a rotating drum cathode inside a fixed anode to grow flakes and to produce them automatically by inherent instability in the deposited film. The drum preferably rotates about a substantially vertical axis. The particulates shed (slough off) into the electrolyte (because of mismatch between the cathode surface and the plated metal or alloy at the molecular level) where they are separated in a magnetic separator or other suitable device. If the flakes are soft iron or iron-cobalt alloys, the drum generally is titanium or titanium alloy.

A truck bed mounted carrier assembly is articulated by a powered pulley taking in or extending a belt to extend on an incline towards ground from the rear of the bed a ramp on which a dolly is translated. The dolly selectively engaged to the end of the belt includes a ribbed cage supporting a watercraft and the combined center of gravity of the dolly and the craft are used to pivot the ramp to an incline once it reaches the limit of its extension. The dolly is then disengaged from the belt for use in launching and recovering the craft.

A data storage medium from which information is reproduced by scanning a surface of the medium with a probe-based tip, such as an Atomic Force Microscope (AFM) tip positioned in contact therewith. The medium comprises a substrate; and a polymer recording surface within which data bit values are determined by the topographical state at the bit location. The polymer contains thermally reversible crosslinkages. The data bit value is a function of the depth of the pit at the bit location.

Failover processing that accommodates failures of backup computing nodes and resources, such as data storage units and printers. Failure of a computing node that controls resources causes another computing node to assume control of the resources controlled by the failed node. Failure of the primary computing node causes another computing node, at either the same or at a different site, to be selected as the new primary node. Failure of a resource at the primary site causes the site with the next highest priority backup resource to become the new primary site. Failure of a backup computing node causes a new backup node at the same site as the failed backup node to replace the failed backup node as host for the site's resources. Backup mirroring data flows are then adjusted to reflect the new functions of the affected nodes.
摘要:
A chlorinated polyethylene elastomer or resin is modified by graft copolymerization with acrylic ester type of monomeric material, whose homopolymers have a glass transition temperature of not greater than 6.degree. C., in an amount sufficient to provide an ester group (--COO--) content of from 25 to 40% by weight, to yield a mixed copolymerizate vulcanizable to a heat and oil resistant elastomeric state.

One example includes a flux switch system. The system includes an input stage configured to provide an interrogation pulse. The system also includes a plurality of flux loops configured to receive an input current. Each of the flux loops includes a Josephson junction configured to trigger to generate an output pulse in response to a first polarity of the input current and to not trigger to generate no output pulse in response to a second polarity of the input current opposite the first polarity. The system further includes an output stage configured to propagate the output pulse to an output of the flux switch system.

A telecommunications network for a high-rise Multi-Dwelling Unit (MDU) is provided. In the telecommunications network eliminates much of the wiring and space required for voice, video and data services, electrical closets, security cameras, building automation, fire annunciation systems, hard-wired smoke detectors, hard-wired heat detectors, electrical meters through the use of an integrated Ethernet communication system. Additionally, a video program guide (VPG) is provided that allows a user to interact with multiple streams of video in real time. The VPG includes techniques for displaying multiple streams of data on a single screen for a user.

An improved, preferably oil-less, air compressor assembly includes a frame and at least a first rotatable cam member mounted to the frame for selective rotation relative thereto. The first cam member has a cam profile. A motor is operatively interconnected with the first cam member for rotating the first cam member. A dual-acting piston assembly includes first and second rods operatively interconnected with a piston received in a piston housing, wherein the piston assembly is mounted relative to the cam profile whereby the piston is stroked upon rotation of the first cam member.
