Aspects of the disclosure are directed to a bolt comprising a head, a first groove formed in a first side of the head and configured to seat a first seal, and an internal feature formed in the head and interfacing with a surface of the head, where the internal feature is configured to enable the bolt to be tightened.

Abstract: An oil tank mounting system for use on a structure of a turbine engine, includes three mounts with each mount configured to constrain the oil tank with a different number of degrees of freedom of movement. A first mount may have fix the oil tank in one degree of freedom, a second mount may fix the oil tank in two degrees of freedom, and a third mount may fix the oil tank in three degrees of freedom. This allows limited rotational and expansion movement while coupling the oil tank to the engine. The mount attachments may be embodied in rubber, with pins, or with spherical joints in a variety of configurations. Frangible pins may be used to absorb energy but still retain the oil tank in the event of a high energy event.

Abstract: A system to effectuate passive check-in with respect to a user's mobile device is described. A server system may be configured to receive communications from a GPS-enabled mobile device (e.g., a mobile phone), extract a stream of locations from the received communications, and use the location information to determine whether a boundary-crossing event has occurred with respect to the mobile device. In response to detecting a boundary-crossing event, the server may communicate a message, such as a recommendation, to the mobile device.

In another embodiment the log can be used to remind the user of the table to change position during the use of the table.

Abstract: The present disclosure relates to shock mounts for turbine engine components. A shock mount may be used to mount an accessory gearbox to an engine case. The shock mount may allow free thermal expansion, while providing damping and stiffness in response to vibrations. The shock mount may include a cylinder filled with fluid, and a piston telescopically moveable within the cylinder. The piston may be coupled to an orifice plate. The orifice plate may include orifices through which the fluid may flow in response to compression or extension of the shock mount. The interaction of the fluid and the orifice plate may resist rapid compression or extension of the shock mount while allowing relatively slow compression or extension of the shock mount.

Abstract: Methods and apparatus for tracking delivery of construction materials from a supplier facility to a jobsite. An ordering module enables customers to place and modify orders before or while delivery occurs. Ticket information for loads shipped from the supplier facility is used to provide up-to-date information about the status of the construction material delivery and to provide an electronic audit trail of activities during the delivery timeline. A social stream integrated with the application enables notifications to be sent to users associated with an order and enables users to add posts with comments including pictures to provide enriched real-time communication between various parties during the delivery.

Abstract: In one aspect, the present invention relates to a wound-care assembly The wound-care assembly includes a base layer. A film layer is operatively coupled to the base layer and a fluid conductor is in fluid communication with a wound and a vacuum source. The wound-care assembly further includes a fiber-optic patch comprising a plurality of fiber-optic strands. The fiber-optic strands are pressed into contact with an interior surface of the wound by the fluid conductor. The fiber-optic patch provides ultraviolet light to the wound and the relative vacuum is applied to the wound via the vacuum source and the fluid conductor.

Abstract: An example method of accessing a valve assembly of a turbomachine includes accessing a check valve of the valve assembly from a first position that is radially outside a flow path through the turbomachine. The method accessing a shut off valve of the valve assembly from a second position that is radially outside the flow path. The check valve and the shut off valve are configured to influence communication of lubricant along a lubricant communication path that extends between a location radially outboard the flow path and a location radially inboard the flow path. The first position is the same as the second position in some examples.
