Patent number: 8494789Abstract: A method of monitoring status of an energy reserve accumulator, connected to a fluid system, includes the following successive operations once the fluid system has stabilized for pressure: measuring a first time taken by the fluid system to progress from a predetermined first pressure to a predetermined second pressure, lower than the predetermined first pressure; measuring a second time taken by the system to progress from a predetermined third pressure, lower than the predetermined second pressure, to a predetermined fourth pressure, lower than the predetermined third pressure; and comparing the first and second times to determine the status of the energy reserve accumulator. Such a method may find use for example in an aircraft.Type: GrantFiled: April 10, 2009Date of Patent: July 23, 2013Assignee: Airbus Operations S.A.S.Inventors: Patrick Boissonneau, Stephan Montillaud

Publication number: 20130185004Abstract: A system, a device and a method are for retrieval of measured values, items of diagnostic information or device parameters in level measurement, pressure measurement, flow measurement or limit detection. Provided in the measuring device is a flag which is raised when the measuring device changes a measuring device parameter, for example. An external control device receives this flag and, using said flag, can determine whether a device parameter has been changed in the measuring device. If this is the case, it requests the group of device parameters, associated with this device parameter, from the measuring device. In this manner, the transfer of data can be reduced.Type: ApplicationFiled: January 8, 2013Publication date: July 18, 2013Applicant: VEGA Grieshaber KGInventor: VEGA Grieshaber KG

Publication number: 20130179111Abstract: A system including an environmental sensor that can travel with a product within a carrier's logistics network. The environmental sensor being configured to sense an environmental condition capable of affecting the product to generate product environment data. The system includes a scanner configured to read product environment data from the environmental sensor. The system also includes a hub control unit configured to communicate with the scanner and receive the product environment data from the scanner and determines whether the product environment data transcends a limit of exposure of the product to an environmental condition. The hub control unit is also configured to generate a transporting instruction to redirect transport of the product to an alternate destination different from its original destination if the hub control unit determines that the product environment data indicates the environmental condition of the product has transcended the limit of exposure.Type: ApplicationFiled: March 1, 2013Publication date: July 11, 2013Applicant: UNITED PARCEL SERVICE OF AMERICA, INC.Inventor: United Parcel Service of America, Inc.

Publication number: 20130138385Abstract: A method of monitoring a Mass Flow Controller (MFC) connected to a pressure chamber for supplying gas to the chamber, which is an unpumped condition, includes cyclically switching the MFC to create successive fill cycles for a test period and measuring the chamber pressure at intervals during the test period. The method is characterised in that the total switch time of the MFC is at least 10% of the fill cycle and in that the method includes obtaining the average of the pressure measurements and comparing them with historical data to determine whether or not the MFC is functioning properly.Type: ApplicationFiled: May 24, 2012Publication date: May 30, 2013Applicant: SPTS TECHNOLOGIES LIMITEDInventors: Simon Jones, Yiping Song
