  • Publication number: 20190124578
    Abstract: Embodiments of the present invention relate to a mobility management entity and a method of determining handover under an Evolved Packet Core Network. The mobility management entity receives signal-to-noise ratio (SNR) information provided by a user equipment with respect to a target base station. The mobility management entity defines a received signal strength indicator (RSSI) and a movement velocity indicator for the user equipment and the target base station according to the SNR information, and determines whether to hand over the user equipment from a serving base station to the target base station according to both of the received signal strength indicator and the movement velocity indicator.

  • Patent number: 9241294
    Abstract: A base station for a communication system and a handoff method thereof are provided. The base station comprises a transceiver and a processor. The transceiver receives a measurement report message with a present reference signal received quality from a wireless device. The processor electrically connected to the transceiver calculates a next report period, estimates a next reference signal received quality and adjusts a first threshold according to a variance of a reference signal received quality. The processor further enables the transceiver to transmit a first measurement control message to the wireless device according to the next report period. The handoff decision process is triggered based on the first threshold and the next reference signal received quality.

  • Patent number: 6283397
    Abstract: A variable and steady yarn feeding apparatus is disclosed. The apparatus comprises a support; a drive device; a steady yarn supply drum for plain knitting; a variable yarn supply drum having a number of high friction resilient yarn guide surfaces, the variable yarn supply drum and steady yarn supply drum both driven by the drive device; a yarn guide device for guiding the yarn from the variable yarn supply drum to the steady yarn supply drum; a self-adjustable yarn guide device provided below the support; and a yarn brake for adjusting the yarn feed of the variable yarn supply drum. An end of a self-adjustable yarn guide device is away from the variable yarn supply drum when there is no yarn demand condition by an expansion of a spring provided therein, while the end of the self-adjustable yarn guide device is in contact with the surfaces of the variable yarn supply drum when there is a yarn demand. A jacquard knitting is made possible by the cooperation of the yarn brake with the variable yarn supply drum.

  • Patent number: 6270032
    Abstract: A variable or steady yarn feeding apparatus comprises a first yarn brake; a support; a steady yarn supply drum for plain knitting; a variable yarn supply drum having a high friction resilient V-shaped or U-shaped surface, the drums both driven by a drive device; a yarn guide device for guiding the yarn from the variable yarn supply drum to the steady yarn supply drum; a self-adjustable yarn guide device provided below the support; and a second yarn brake for adjusting the yarn feed of the variable yarn supply drum. An end of the self-adjustable yarn guide device is away from the variable yarn supply drum in a no demand condition by an expansion of a spring provided therein, while the end is in contact with the surfaces of the variable yarn supply drum when there is a yarn demand. A jacquard knitting is made possible by the cooperation of the second yarn brake with the variable yarn supply drum.

  • Patent number: 6149092
    Abstract: A yarn supply apparatus for knitting machines is provided wherein an outgoing yarn guide eye set is disposed laterally adjacent to and lower than an underside of a yarn supply drum; a yarn pull-out section with a vertical circumferential surface is slightly inclined toward the circumference of the underside of the yarn supply drum such that when the yarn unwinding from the yarn supply drum the yarn will be vibrated upward and downward rapidly for being completely in contact with the circumferential surface of the yarn pull-out section so as to filter out dirt adhered on the yarn and nap accumulated on the circumferential surface of the yarn pull-out section. As a result, the manual cleaning work will be minimized.

  • Patent number: 6102320
    Abstract: A yarn supply apparatus with dual feeding features is disclosed. The apparatus is characterized in that a yarn guide arm is fabric yarnedly secured on the front top side of a support holder of the apparatus having an inner and an outer yarn eyes provided thereon in order to enable a short and a long fabric yarn knittings without a yarn brake detachment-and-mounting procedure.

  • Patent number: 5839685
    Abstract: The thread feeding wheel is capable of preventing static-electricity from being produced due to rapid feeding of the thread and which provides a surface having a low frictional coefficient so that the thread feeding around the thread feeding wheel would subject to minimal frictional damage. The cylindrical body is made of an aluminum alloy. A layer of oxide of the aluminum alloy is formed by a hard anodizing process on the middle portion of said cylindrical body. A layer of polytetrafluoroethylene resin is impregnated over said oxide layer to further reduce the frictional coefficient of the thread running surface.

  • Patent number: 5388747
    Abstract: An positive yarn feeding device including a support body mounted on a beam member, a multilayer yarn feeding wheel having frictional yarn feeding periphery, multiple drive pulleys, multiple tension controllers each having a movable yarn guiding arm, and a yarn braking assembly. The yarn feeding wheel and the drive pulleys are rotatably concentrically secured in a bearing of the support body and a clutch is disposed between the pulleys for optionally adjusting the operating speed of the roller. Each movable yarn guiding arm is disposed with a yarn guiding eyelet through which a yarn passes. The movable yarn guiding arm is pivotally supported between a first position where the yarn guiding eyelet is away from the frictional periphery of the yarn feeding wheel, and a second position where the yarn guiding eyelet is adjacent to the frictional periphery thereof.
