  • Patent number: 10244024
    Abstract: A method, implemented at a server of an operations control center of a telematics service provider, for transmitting commands to a network access device, is described. The method involves creating one or more command data packets, each comprising a payload and control information, the control information identifying an AT command air interface. The method further involves transmitting, by the server, the command data packets to the network access device via the AT command air interface, wherein the AT command air interface is a first tunnel extending through a network of the vehicular telematics unit. In addition, a method, implemented at a baseband processor of a network access device of a vehicular telematics unit, for receiving commands from a server of an operations control center and a system for transmitting commands between a server of an operations control center and a network access device are also described.

  • Publication number: 20180230838
    Abstract: A shroud segment arranged radially outward of a gas flow path of a gas turbine. The shroud segment includes a body having walls defining an internal pocket for receiving a supply of air. A plurality of pressurization apertures is formed through one of the walls to fluidly connect an internal pocket of the body to an ambient area of the body. A seal slot section is formed in the wall at a position radially inward of the pressurization apertures to receive a seal to connect the shroud segment to an adjacent shroud segment. The pressurization apertures are arranged such that portions of the supply of air are configured to pass through the pressurization apertures and through the seal slot section as leakage into the gas flow path, thereby reducing ingestion of fluid from the gas flow path into the internal pocket of the shroud segment.

  • Patent number: 9645247
    Abstract: A method is described for estimating the coordinated universal time (UTC). The method involves receiving, by a satellite navigation receiver, signals broadcast by a global navigation satellite service (GNSS) satellite. The signals encode a first time of week (TOW) value. The method also involves estimating a first week number (WN) value and a first relationship between the UCT and a reference time of an onboard clock of the GNSS satellite (OFFSET) from time parameter values stored at a local memory. The method determines a first estimate of the UTC from the first TOW value, the first WN value, and the first OFFSET.

  • Patent number: 9445447
    Abstract: A system and a method for establishing short range wireless communication between two vehicle modules. The system determines the availability of a first vehicle module and a second vehicle module to establish a short range wireless communication connection. The determination may be based upon whether the first vehicle module is storing pairing data. The system validates the pairing data at the second vehicle module using a wired connection. If the pairing data is validated, the first and second vehicle modules may establish a wireless connection using at least a portion of the pairing data. When the wireless connection ends, the system may re-determine the availability and revalidate any pairing data via the wired connection before establishing a wireless connection.
