Abstract: Method for configuring, commanding and/or controlling a command and/or control interface (IN) of devices of a home automation installation, comprising the following steps: (E1) collecting a set of status queries (E) relating to at least one possible status of at least one home automation device (3), (E2) constituting a selection of at least one status query (SeIE) of the set of status queries (E), (E3) configuring an interface element (IN) on the basis of the selection of the at least one status query (SeIE), in such a way as to trigger transmission of a collection request (RC) comprising the selection, and obtaining, for each status query (E) of the selection, of at least one corresponding status indication (IDC) relating to at least one current status.

Abstract: An apparatus for dampening acoustic pressure oscillations of a gas flow contained in part by a combustor wall of a gas turbine engine combustor. The apparatus includes at least one resonating tube with a closed end, an open end, and a cavity therebetween. The cavity is in fluid communication with an interior of the combustor such that the gas flow may flow into and out of the cavity. The apparatus further includes a perforated plate positioned at the open end and including a plurality of apertures. The gas flow flowing into and out of the cavity travels through the apertures.

Abstract: A gas turbine engine combustor conical-flat heat shield includes an annular conical section extending upstream from and being integral with a flat section with a flat downstream facing surface which may be generally perpendicular to or canted with respect to a centerline. The flat section includes radially outer and inner edges at least one of which is circular and circumscribed about a centerline and circumferentially spaced apart clockwise and counter-clockwise radial edges having an origin on the centerline. A gas turbine engine combustor includes conical-flat heat shields in one or more circular rows arranged in a non-symmetrical or asymmetrical pattern. Two or more groups (A, B, C) of the conical-flat heat shields in the circular rows may be mounted on a domeplate and one or more of the conical-flat heat shields is different in one or more of the groups (A, B, C).
