Abstract: A method, apparatus, and computer program product for managing movement of a flight control surface on an aircraft. A control signal is received to move the flight control surface to a position. Travel in a number of actuators in a plurality of actuators coupled to the flight control surface is limited to an amount that reduces a load on the number of actuators in the plurality of actuators in response to receiving the control signal while the aircraft is on the ground and the speed of the aircraft is less than a threshold.

Abstract: A sewing ring for prosthetic heart valves that is connected and configured to pivot outward. A biocompatible fabric covering surrounds at least a portion of the sewing ring, and the ring may be exclusively connected to a stent with the fabric. The sewing ring may be generally planar and of uniform thickness, or may be of varying thickness. The fabric may be used to encompass both the stent and the sewing ring, and may be a single piece. A seam may be provided in the fabric as a discrete pivoting line. The sewing ring may be convertible between bi-stable positions. The ring may extend outward in a frusto-conical shape so as to enable inversion between a position facing the inflow end of the valve and a position facing the outflow end of the valve. The sewing ring may have a compliant insert having a celled construction defined by outer walls and inner ribs. A method of implantation, and a method of assembly of the heart valve is also provided.

Abstract: Methods and apparatus for reacting rotary actuator and control surface loads into a wing structure using reaction links. The apparatus incorporates a structural interface feature that can facilitate a change of the component(s) in the load loop, such as the path connecting a control surface to a fixed aircraft structure via a rotary actuator. In particular, the structural interface between the rotary actuator and the rear spar of a wing can be tuned for stiffness to achieve an optimized load path that reacts actuator and control surface loads back into the wing structure. An actuator integration objective can be met for any rotary actuator using an integration method which tolerates wing and/or hinge line deflection.

Abstract: Provided is a method of epitaxial deposition, which involves dry-etching a semiconductor substrate with a fluorine containing species and exposing the dry-etched substrate to hydrogen atoms, prior to epitaxially depositing a semiconductor layer to the surface of the substrate.

Abstract: A master-slave robotic endoscopy system includes a flexible primary endoscope probe having at least one tool channel for carrying a tendon-sheath driven robot arm and corresponding end effector, and a secondary endoscope probe channel for carrying an imaging endoscope. The imaging endoscope provides enhanced image capture range relative to a distal end of the primary endoscope probe by way of a secondary endoscope probe channel distal opening proximally offset from the primary endoscope probe distal end; a ramp structure distally carried by the primary endoscope probe; and/or one or more actuatable distal imaging endoscope regions. Robot arms can include joint primitives that enable robot arm/end effector manipulation in accordance with intended degrees of freedom.

Abstract: A method, apparatus, and computer program product for managing movement of a flight control surface on an aircraft. A control signal is received to move the flight control surface to a position. Travel in a number of actuators in a plurality of actuators coupled to the flight control surface is limited to an amount that reduces a load on the number of actuators in the plurality of actuators in response to receiving the control signal while the aircraft is on the ground and the speed of the aircraft is less than a threshold.

Abstract: Improved ball valve or pig valves with stems having higher stress yields are disclosed. Additionally, a method of changing using the same stem in a ball valve or pig valve in a low pressure application or a high pressure application is disclosed. Furthermore, a method of ensuring a correct stem is matched to a correct ball of a ball or pig valve is disclosed.

Abstract: A method and apparatus for processing a model of a part. A number of locations are identified in the model of the part in response to receiving a request from a client application for information about the number of locations on the part. A section cut is created at each of the number of locations to form a number of section cuts. Data is obtained for layers in each of the number of section cuts. The model with the number of section cuts is changed to form a formatted model with a format used by the client application. The layers in each of the number of section cuts in the formatted model are associated with the data for the number of layers in the each of the number of section cuts. The formatted model and the data for the layers is returned to the client application.

Abstract: A foldable support structure serving as a work surface having apertures that may differ diametrically for support of containerized articles, such as beverages. The foldable support structure has three hinged planar sections with the center section having the aforementioned apertures and the left and right sections incorporating means for fixedly engaging each other. Mating straps extend substantially from a hinged joint and from a section base whereby said foldable support can be suspended from a structure, such as a motor vehicle seat. Tongue and slots positioned on opposing section ends provide means for selectively varying the pitch of the work surface. The device can be used as a free standing table for bed or beach having selectively engageable locking mechanisms positioned on the four corners of the center section and normally in a disengaged position so that the left and right sections are free to move to a user selective engagement between tab and slot.
