Publication number: 20140378055Abstract: 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.Type: ApplicationFiled: June 20, 2013Publication date: December 25, 2014Inventors: Dipankar Pal, David P.

Patent number: 8764379Abstract: A turbine blade for a turbine engine includes main coolant passageways which extend through the turbine blade to cool the blade. A tip coolant passageway conveys coolant from a location adjacent the base of the blade directly to the tip of the blade to provide cooling fluid directly to the tip of the blade. This ensures that the coolant arriving at the tip of the blade is at a relatively low temperature and can therefore provide effective cooling of the material located at the tip of the blade.Type: GrantFiled: February 25, 2010Date of Patent: July 1, 2014Assignee: General Electric CompanyInventor: Dipankar Pal
