摘要:
An Internet Access Device (IAD) is pre-configured with first, generic configuration information designating the address of a configuration server with which it will establish a communication session when the IAD is first powered up and connected to the Internet. The configuration server then downloads a second, specific configuration to the IAD, such as a hotline number designating a specific speech server, and creates a network data record to link a unique identifier for the IAD, such as a serial number, with a user account. When the IAD goes off-hook, the IAD connects directly to a speech server using the second configuration. The speech server provides a smart dial tone, such as a voice prompt. The speech server responds to a verbal request spoken by a user by performing a corresponding activity, such as placing a telephone call or providing voicemail access.

摘要:
An accessory box for a gas turbine engine has an input gear to be driven by an input shaft. The input gear is engaged to drive a first driven gear on one radial side of a drive axis of the input gear. The first gear drives at least a second driven gear on one radial side of the drive axis, with at least one accessory driven by one of the first and second driven gears. The second driven gear drives a bevel gear arrangement to drive a third driven gear on an opposed side of the drive axis of the input gear. The third driven gear drives at least a second accessory. The accessories are associated with a gas turbine engine.
摘要:
An accessory system for a gas turbine engine includes an accessory gearbox which defines an accessory gearbox axis and includes first and second sides. A first geartrain includes one or more shafts rotatable about axes perpendicular to the first side of the accessory gearbox and a second geartrain includes one or more shafts rotatable about axes perpendicular to the second side of the accessory gearbox. A driven gear set defines an input axis and drives first geartrain and the second geartrain about corresponding first and second drive axes parallel to the input axis.

摘要:
A solution based polymer nanofiller composite processing method to improve mechanical, electrical, thermal and/or chemical properties. The solution based synthesis method may include the steps of surface functionalizing carbon nanomaterials and dissolving a polymer in a solvent. The functionalized carbon nanomaterials and dissolved polymer may be mixed until the mixture is homogenous. The mixture may be cured to form the polymer carbon nano-composite material, which provides significant improvements in modulus, hardness, strength, fracture toughness, wear, fatigue, creep, and damping performance.
