  • Thermal mechanical diffusion system and method
    Patent number: 9526129
    Abstract: Provided is a thermal mechanical diffusion system and method. In accordance with the present invention, one end of a fiber under tension is vibrated while a portion of the fiber is heated. A push-pull action of one end of the fiber forces increased (or rapid) diffusion of dopants in the portion of the fiber that is in a heat zone, which receives the heat. By controlling the amplitude and frequency of the vibration, a diffusion profile of one or more fibers can be dictated with precision. Heat sources having narrower thermal profiles can enable greater precision in dictating the diffusion profile. As an example, this can be particularly useful for creating a diffusion taper within a fiber to be spliced, where the taper is a result of thermal expansion of the fiber core. Diffusion can occur much more rapidly than is typical.

  • Sleeve shrinking quick dip system
    Patent number: 6495803
    Abstract: A system and method for quickly heating a shrinkable casing around a relatively non-shrinkable object. The system may be referred to as a sleeve shrinking quick dip heat system. As one example, the present invention may be used to shrink a sleeve around a strand, such as fiber or copper. In the electrical and electronic fields, the present invention may be used to shrink sleeves or tubing around, for example, copper strands, wires, connectors, or components. A contact approach to heating the a loaded sleeve is used wherein a predetermined temperature profile is applied to prevent the trapping of air during shrinking. Ramp-up time is eliminated by use of a heater block that remains near or at heat shrinking temperatures, while selectively transferring heat to the sleeve according to the desired temperature profile.

  • Method and apparatus for stripping an optical fiber
    Patent number: 6402856
    Abstract: A system for stripping an optical fiber includes a source air, and means for generating very short bursts of air. A heater heats the bursts of air to a temperature sufficient to remove the outer coating from an optical fiber, while maintaining the air isolated from the heat source. The heater includes a heater core that includes a heat generating element such as a conductive filament, and a heat chamber enclosed within the heater core. A spiral-shaped air conduit surrounds the outer surface of the heater core, and communicates with the heat chamber. Upon injection of air into the conduit, heat is transferred to the air from the heat generating element while the air flows through the air conduit and into and out of the chamber. A single burst of heated air removes the outer coating of an optical fiber, within less than one second.

  • Method of cleaning and stripping an optical fiber using an electrical arc, and associated apparatus
    Patent number: 7555188
    Abstract: A method and apparatus for processing an optical fiber includes generating a continuous or pulsed arc in a first area wherein the arc creates a plasma in one or more gasses in the first area. The method further includes positioning a portion of the fiber in a second area adjacent to and outside of the plasma region, wherein coating material that is present on the optical fiber portion is removed when the plasma is present. Alternatively, in the case of a pulsed arc, the optical fiber portion may be positioned at least partially within the plasma region. The positioning step may be performed prior to or subsequent to the arc generating step. The method and apparatus may be utilized in a system that also strips and cleaves optical fibers. Also, a method for reducing the gap resistance between two electrodes by injecting negative ions into the area between the electrodes.

  • Translatable fiber stripper
    Patent number: 6607608
    Abstract: A system for stripping an optical fiber includes a source of air and means for generating very short bursts of air. A heater heats the bursts of air to a temperature sufficient to remove the outer coating from an optical fiber, while maintaining the air isolated from the heat source. A single burst of heated air removes the outer coating of an optical fiber, within less than about one second. A series of closely spaced bursts or a prolonged burst of heated air may be used to remove an expanded length of fiber coating. Stripping may include translation of the fiber or the heater or portions thereof. The stripper may be configured to strip several loaded fibers or a single fiber.

  • METHOD AND APPARATUS FOR PERFORMING ATTACHMENT PROCEDURES
    Publication number: 20080181178
    Abstract: A method and apparatus for implementing an attachment procedure in multi-mode systems are disclosed. A wireless communication system includes at least one of a second generation (2G) system, a third generation (3G) system, a long term evolution (LTE) and system architecture evolution (SAE) of the 3G system and a non-3G system. For performing an attachment procedure, a wireless transmit/receive unit (WTRU) sends an attach request message to a new serving general packet radio service (GPRS) support node (SGSN) indicating an attach type. The new SGSN and the WTRU then perform an attachment procedure based on the attach type. The attach type may indicate a GPRS only attachment, a GPRS and SAE attachment, or a 3GPP and non-3GPP attachment.

  • Fast update message authentication with key derivation in mobile IP systems
    Publication number: 20080207168
    Abstract: The present invention performs a Binding Update or a Location Update message authentication independently and terminal-specifically in a home SAE gateway. A key, which is derived in a home AAA server from an initially set long term key, is given to a visited network for encrypting the update messages in Proxy Mobile IP. In Client Mobile IP, the key is transmitted to a mobile node for update message encryption. When the update message is received in the home SAE gateway, the key can be derived independently in the home SAE gateway without any key requests between the gateway and the home AAA server. Thus, it is possible to authenticate the binding or location update messages by verifying the two signatures. The present invention can also be implemented on a lower hierarchy of the system. The invention can be implemented in 3GPP standard releases enhanced with LTE technology, for instance.
