Patent number: 9094898Abstract: A method and apparatus adaptively scan communication channels to find a channel having a desired attribute such as being usable for communication with a home network in one of a plurality of communication modes. A first scan of a first set of channels is performed, and attributes are assigned to channels. If a channel having the desired attribute is not found, the attributes are used to configure a second scan of a second set of channels using a second scan mode, such that the expected amount of resources consumed in the second scan is reduced, for example by scanning channels more likely to be usable for communication first. The second scan of a second set of channels is performed, and additional attributes are assigned to channels. If a channel having the desired attribute is found during the first or second scan, the scan may terminate.Type: GrantFiled: December 2, 2013Date of Patent: July 28, 2015Assignee: NETGEAR, Inc.Inventor: Kevin Walton

Patent number: 8964549Abstract: The present invention provides a method for managing communications of a wireless device in a wireless communication system based on network traffic level, and a wireless device comprising a control system configured to evaluate a network traffic level. The wireless device may be configured to transmit data, such as delay-tolerant data, based upon the network traffic level, for example transmitting data only under low traffic conditions. Deferring delay-tolerant communications may result in lower peak traffic conditions in the network. Evaluating the network traffic level may comprise measuring chip energy over total energy (Ec/Io), monitoring data on shared control channels such as HS-SCCH of a HSDPA system, inferring power allocated to channels by a dynamic power allocation scheme, or other methods.Type: GrantFiled: June 21, 2011Date of Patent: February 24, 2015Assignee: Sierra Wireless, Inc.Inventors: Gustav Gerald Vos, Kevin Walton, Recep Serkan Dost

Patent number: 6409472Abstract: A stator assembly for a rotary machine having a shroud for a stator vane is disclosed. Various construction details are developed which limit movement of the stator vane into the flowpath by reason of the stator vane being restrained by the shroud. In one particular embodiment, a clip member extends through an opening in the tip of the vane and is disposed at a location adjacent a nonflowpath surface of the shroud to restrain the tip of the vane against inward movement through the shroud.Type: GrantFiled: July 31, 2000Date of Patent: June 25, 2002Assignee: United Technologies CorporationInventors: Michael E. McMahon, Robert B. Richardson, Steven J. Feigleson, Keith T. Honda, Christopher G. Demers, Michael A. Servadio, Kevin A. Walton

Patent number: 6212770Abstract: A method for forming a rotor assembly for guiding motion of one circumferentially extending structure with respect to a second structure is disclosed. Various steps of the method are developed and include forming a pin for receiving a rotatable element for the roller assembly. In one particular embodiment the method includes forming the pin with a one-piece head and trapping the rotatable element between the pin and support structure for the pin.Type: GrantFiled: February 26, 1999Date of Patent: April 10, 2001Assignee: United Technologies CorporationInventors: Keith T.

Patent number: 6161839Abstract: The invention is a valve seal assembly (43) illustrated in the context of a compressor bleed valve (36) for a gas turbine engine. The seal assembly includes a seal carrier (44) having a circumferentially extending groove (72) bordered by a pair of opposing flanges (74). The flanges cooperate to define a recess (76) portion of the groove and a throat (78) portion of the groove. The seal assembly also includes one or more seal elements (46) each having a base (82), conformal with the recess, and longitudinally captured in the recess by the flanges. A stem (84) extends from the base and projects through the throat, and a sealing bead (86) extends from the stem. An insert (88) extends circumferentially in the base for stiffening the base about a circumferential bending axis (C). An access port (96) facilitates installation and removal of the seal elements (46) and a cover (98) traps the seal elements in the carrier (44).Type: GrantFiled: February 27, 1998Date of Patent: December 19, 2000Assignee: United Technologies CorporationInventors: Kevin A. Walton, Joseph H. Campana

Patent number: 6106227Abstract: A roller assembly for guiding the motion of a circumferentially extending ring in a gas turbine engine, where the roller assembly has a pin and a collar. The pin has a head which engages a rotatable element, which in turn adapts the roller assembly to engage a track and which adapts the roller assembly to receive an external force from the track under operative conditions, causing a reactive force on the rotatable element to resist the external force. A gap formed between a shank of the pin and the collar decreases the bending stresses in the shank in comparison to forces acting on the pin at an end of the collar which engages a support.Type: GrantFiled: February 26, 1999Date of Patent: August 22, 2000Assignee: United Technologies CorporationInventors: Keith T. Honda, Kevin A. Walton, Francis J. Sandini
