Abstract: A manufacturing process of a fibrous preform for a composite material includes creating a fibrous texture by three-dimensional or multilayer weaving between a plurality of weft layers and warp layers, the fibrous texture including an extra-thick portion having a sacrificial portion and a useful portion adjacent to the sacrificial portion in the warp direction, the sacrificial portion, placing the fibrous texture in a forming toolset, shaping the fibrous texture so as to obtain a fibrous preform having a sacrificial portion and an adjacent useful portion, removing the sacrificial portion from the fibrous preform. When weaving the fibrous blank, one or more expansion elements are inserted into the weft layers located at the core of the sacrificial portion of the fibrous texture. Each expansion element has a cross-section greater than the cross-section or count of the weft threads or strands present in the useful portion.

Abstract: A re-usable, compact automated external defibrillator (AED) having a proximate electrode and a distal electrode for use in delivering an electrical charge to a person in cardiac distress. The components of the AED are packed together in a low-profile device body. The distal electrode may be easily unpacked from the device body and deployed. A circuit board within the device body controls the AED. The proximate electrode is part of the device body such that the device body is attached to the skin of the person when in use. The distal electrode is wired to the device body and also attached to the skin of the person when in use. The circuit board may be used to deliver a biphasic electrical charge to the person. The adhesive pads on the electrodes may be peeled off and replaced for reuse. Also, the electrodes may be replaced, if needed.

Abstract: Based on data indicative of an area proximate to a robotic device, a scene is generated. Based on information from a knowledge database, a task associated with the scene is identified. A risk threshold is determined based on the scene, the task, and one or more trust thresholds. Based on the risk threshold, a ratio of sub-tasks of the task to be controlled by a user is determined. In accordance with the risk threshold, a user input is received for controlling one or more of the sub-tasks when the ratio dictates that at least one of the sub-tasks requires user intervention.

Abstract: A handheld guide for advancing and installing a decking fastener with an elongate track with a rail and an advancement member. The advancement member carries a pivoting pawl with an engagement surface for advancing fasteners forward through the track to an installation position with a frontmost fastener aligned with a screw guide for driving a screw through the frontmost fastener. The rail has a ramp transitioning to a cliff and a lower ledge such that the frontmost fastener is maintained forward of the cliff above the ledge in the installation position. The pawl pivots to disengage from the fasteners when the advancement member moves rearwardly along the track.

Abstract: An automated fluid maintenance system comprising a sensor system and a pump configured to deliver fluid from a refillable reservoir to a container holding a Christmas tree, such as a Christmas tree stand. Embodiments of the system include tree attachment hardware capable of controlling the flow, delivery and direction of the fluid being pumped from the of the fluid system's reservoir to a fluid-holding container of the Christmas tree stand and further capable of securing the point of fluid delivery to the tree stand and/or the tree itself. The tree attachment device universally attaches to any available tree stand, even the most complex stand mechanisms, sizes and shapes that obstruct the path to the Christmas tree being maintained by the automated fluid delivery system of the present application.

Abstract: A turbine ring assembly includes ring sectors made as a single piece of ceramic matrix composite material and being for mounting on a metal ring support structure, the ring support structure having two tabs extending radially towards a gas flow passage, each ring sector having a first portion forming an annular base with a radially inside face defining the inside face of the turbine ring and an outside face from which there extend two tab-forming portions, the ring sectors having a section that is substantially ? shaped. The tabs of each ring sector fit axially over the tabs of the ring support structure with contact between the tabs of the ring support structure and the tabs of each ring sector when cold. The tabs of each ring sector are held to the ring support structure by pegs passing through holes formed in the tabs of each ring sector.

Abstract: A turbomachine rotor blade includes an outer part at its distal end. The outer part includes a platform defining an outside surface of a passage for gas passing through a turbomachine and presenting first and second opposite side edges; and upstream and downstream sealing wipers extending outwards from the platform, each wiper extending between two lateral faces situated respectively at the first and second side edges. The two lateral faces of the upstream or the downstream wiper are covered at least in part in an anti-wear material.

Abstract: A portable ground blind device having a sheet of material combined with a frame assembly. The frame assembly includes a connector member pivotally combined with one or more leg support members for supporting the device on the ground surface and one or more arm members for supporting a top portion of the sheet. The sheet may include sleeves or casings adapted to receive portions of the support members and arm members to combine the sheet with the frame. The sheet covers the leg support members to form a three dimensional covered pocket under the frame. The arm members may include pivot joints for adjusting a first arm member portion relative to a second arm member portion, each portion can be separately adjusted relative to the frame assembly. A gun rest is adjustably combined with the connector member.

Abstract: A window insulating film roll and kit for insulating windows or a sheet such as a bug screen for covering other types of dwellings. The window insulating film of translucent or transparent polymer has a pair of longitudinal edges and a pair of lateral edges transverse to the longitudinal edges, a strip of adhesive along one of the longitudinal edges, a releasable backing strip covering the strip of adhesive. The window insulating film is rolled about an axis generally parallel to the longitudinal edges starting with the longitudinal edge away from the backing strip to form an elongated film roll, the elongated film roll being rolled about an axis generally transverse to the longitudinal edges to form a window insulating film roll, A dispenser has a receptacle for rollingly receiving the window insulating film roll, a dispensing outlet being defined in a wall of the receptacle for a free end of the window insulating film roll to pass therethrough during dispensing.

Abstract: A door sweep comprises an elongated U-shaped body formed by a base and a pair of upright walls, the U-shaped body configured for being mounted to a bottom portion of a door. The elongated U-shaped body may float relative to the bottom portion of the door when installed. Biasing member(s) in the elongated U-shaped body may bias the downwardly base away from the bottom portion of the door. A fastener cover may be connected to one of the upright walls, with a hinge formed at a junction between the fastener cover and U-shaped body, for hinging the fastener cover. Hinges may be formed at a junction between the base and each of the upright walls, for hinging the upright walls.

Abstract: A blade preform includes a strut connecting a plat-form to a blade root portion extending longitudinally in an upstream-downstream direction, an upstream web and a downstream web, which each extend in a direction substantially perpendicular to the longitudinal direction of the blade root and are formed at the upstream and downstream ends of the strut. The upstream and downstream webs connect the upstream and downstream ends of the plat-form to the upstream and downstream ends of the blade root. The blade root extends in a direction perpendicular to the longitudinal direction of the blade root over a distance smaller than that of the upstream and downstream webs and the side edges of each web are extended by walls that converge at the flanks of the blade root.
