Abstract: Methods and systems are provided for an awareness intelligence headphone with an always listening mode. Headphone units share the ability to output audio sound to a user, but may not provide additional functionality that users may require. A headphone unit with the always listening mode is used to analyze ambient noise surrounding the headphone unit in order to detect predetermined sounds, issue alerts to a user, and respond to an input command from the user.

Abstract: A method for allowing multiple audio sources to play sound through an audio speaker system is disclosed.

Abstract: A system and method for facilitating connecting a switch to a network to improve network performance. In an illustrative embodiment, the system includes a first module for determining when the switch is initially connected to a network and providing a signal in response thereto. A second module selectively forms adjacencies with peers of the switch in response to the signal and based on one or more predetermined parameters. In a more specific embodiment, the switch is a router or Layer-3 (L3) switch. The one or more predetermined parameters include a load factor, values pertaining to capabilities of a processor included in the router, bandwidth capabilities of the interface and/or the router, internal router queue counts, and so on. The router employs a routing protocol such as Enhanced Interior Gateway Routing Protocol (EIGRP). The second module throttles and adjacency-formation rate based on the predetermined parameters.

Abstract: A turbine inner shell for a turbine engine includes one or more mounting grooves, each of which receives a fluid conduit. A temperature controlling fluid is circulated through fluid conduit to selectively heat or cool surrounding portions of the turbine inner shell, to thereby control the thermal growth of those portions of the turbine inner shell. This makes it possible to selectively control a clearance between the tips of rotating turbine blades and the surrounding shrouds of the turbine.

Abstract: This disclosure pertains to the field of small-unmanned aerial vehicles (UAVs). The delta wing vehicle consists of an isosceles triangular shaped lifting body milled from Styrofoam. The longitudinal axis is approximately 65% of the lateral axis. The horizontal wing projections, or tiplets, are attached to the main lifting body at an approximately 10 degree upward angle from horizontal, have a 30 degree sweep back leading edge, and each one comprises 5% of the total wing area. The airfoil is a rhomboid or diamond shape. The chord is swept back at a 45-degree angle from the longitudinal centerline. The airfoil is symmetrical about the longitudinal center. The aircraft is controlled by a set of combined elevator/aileron surfaces (elevons) at the rear as well as a vertical stabilizer/rudder combination. This resulting lightweight UAV can make flat (unbanked) unbanked turns, fly in high winds, and has superior flexibility in payload capability.

Abstract: A product delivery mechanism for a beverage dispensing system that dispenses flavor/ingredients and ice into a serving cup for mixing and/or blending. The product delivery system includes a gas operated pump for moving the flavor/ingredients from a product source to a dispensing nozzle above the serving cup. A gas restrictor is connected to an exhaust port of the pump to regulate gas flow rate and product flow rate so as to prevent splashing at the cup while operating the pump well within its rated pressure limits.

Abstract: A tube holder for use in turbomachinery includes a housing having a passage for receiving a tube, the housing adapted for attachment to a turbomachinery component; and a metal foam component located within the housing and arranged to engage a length portion of the tube to thereby hold the tube within the housing and reduce undesirable vibrations in the tube during operation of the turbomachinery.

Abstract: This disclosure relates generally to the field of unmanned aircraft systems (UAS), specifically to launch, fly and land unmanned aerial vehicles (UAV). This disclosure describes a system comprised of a UAV, a portable launch pad, a telescoping landing net and an integrated RFID system. This system provides a unique combination of UAV performance and payload capabilities with integrated Radio Frequency Identification Device (RFID) electronic systems capable of withstanding extreme weather conditions including high winds in remote locations.

Abstract: A thermal isolation apparatus is provided and includes an annular casing surrounding a turbine bucket stage and defining an annular recess from an interior facing surface thereof, an annular shroud disposed within the casing to provide for a predefined clearance about rotating bucket tips of the turbine bucket stage, the shroud including an annular main member and an annular flange extending from an outwardly facing surface of the main member and being sized to fit within the recess and a thermal barrier formed of porous material, which is interposed between opposing surfaces of the casing and the flange within the recess.
