Abstract: A set-top box with enhanced features and system and method for use of the same are disclosed. In one embodiment of the set-top box, the set-top box is deployed to provide an interactive portal in a hospitality establishment having multiple rooms, such as a hotel. The set-top box generates a default interactive portal as well as a guest-specific interactive portal, which is generated from a guest configuration profile having information including guest identification, a guest channel preference presentation, and a guest service preference presentation with guest account information. The guest configuration profile may also enable the creation of a local area wireless network with substantially the same behavior as the guest's home wireless network. The guest configuration profile may further enable the control of in-room amenities, such as temperature control, lighting, shades, and availability, for example.

Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

Abstract: According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed.

Abstract: An aircraft structural component, for example, a wing spar that has an I-beam shape having upper and lower spar caps coupled by a web therebetween and that provides structural support for an aircraft wing. The wing spar may be fabricated as a graphite composite that is thermally cured to have a certain stiffness. In one embodiment, the wing spar is fabricated so that the upper spar cap has a higher CTE than the web, which creates tension forces in the spar cap when the spar is thermally cured and then cooled. Therefore, when the wing spar is mounted to the wing and the aircraft is in flight, compression forces on the wing skin act to relieve the tension forces in the spar cap, which reduces the compression buckling load on the wing.

Abstract: A latching mechanism is provided for engaging an aircraft surface panel to a support member. The aircraft panel is provided with a post extending from the lower surface, which extends through a panel support member into a post engagement mechanism. The post engagement mechanism defines a rotatable sleeve, which rotates for locking and unlocking engagement between the post and the post engagement mechanism. Locking engagement continues when power to the post engagement actuator is terminated. The post engagement mechanism may utilize various types of actuators, including mechanical, hydraulic, and pneumatic. The aircraft panel and the panel support member are translatable into and out of abutting engagement independent of the need for any contact with the aircraft panel upper surface.

Abstract: A permanent faster is disclosed that utilizes an amorphous metal alloy for a retaining collar that is thermoplastically formed on install. The fastener includes a headed pin with locking grooves disposed thereon and a collar having a cylindrical inner wall. Head geometry may be any suitable shape; countersunk, counter bore, flat, etc., and may also be non-rotationally symmetric. The pin is disposed into aligned holes through the work pieces to be secured, and the collar is disposed about the pin over the locking grooves. The collar is heated into a thermoplastic region, something only allowed because of the amorphous metal material properties. The cylindrical wall of the collar is then radically compressed into the locking grooves to affix the collar on the pin. The amorphous metal properties allow use of a smaller fastener, and the thermoplastic region is reached at a temperature which does not damage composite work pieces.

Abstract: A bi-directional coupler that selectively couples and de-couples a driving element to a driven element. The coupler includes an outer shaft having an outer shaft slot and an inner shaft having an inner shaft slot, where the inner and outer shafts are configured to rotate independently of each other. The coupler also includes a ball bearing provided within the inner shaft slot and having a size so that when the ball bearing is located at a center portion of the inner shaft slot it does not interfere with rotation of the outer shaft, where the ball bearing is held in that location by a magnet located in the inner shaft. Rotation of the inner shaft above a predetermined rotational speed causes the ball bearing to engage the outer shaft slot so as to cause the inner shaft to be locked to the outer shaft and rotate therewith.

Abstract: A method for providing air traffic controlled flight of drones flying in to and out of an air traffic controlled space around an airport. The method includes causing the drones to congregate at a congregation area in the air traffic controlled space, causing the drones to fly from the congregation area as a group out of the air traffic controlled space under air traffic control, causing the drones to disperse from the group once the drones are out of the air traffic controlled space, causing the drones to fly to a package delivery location after they are dispersed to deliver the package, causing return drones to fly to a re-congregation area outside of the air traffic controlled space after they have delivered their packages, and causing the return drones to enter the air traffic controlled space as a group under air traffic control.

Abstract: A method for providing air traffic controlled flight of a large number of commercial drones each carrying one or more packages in to and out of an air traffic controlled space around an airport. The method includes providing an outbound corridor from a carrier facility through and out of the air traffic controlled space, where the outbound corridor does not allow any other air traffic to fly therein, and allowing the drones to fly through the outbound corridor to leave the air traffic controlled space without requiring air traffic control. The method also includes providing an inbound corridor through the air traffic controlled space to the carrier facility that does not allow any other air traffic to fly therein, and allowing drones to return to the carrier facility through the air traffic controlled space by flying through the inbound corridor without requiring air traffic control.

Abstract: A magnetic fastener assembly for securing an access panel to an aircraft structure. A panel magnetic foundation member is rigidly secured to a surface of the panel facing the aircraft structure and a land magnetic foundation member is rigidly secured to a surface of the aircraft structure facing the panel. A planar magnet is positioned between the panel magnetic foundation member and the land magnetic foundation member and being magnetically coupled thereto so as to secure the panel to the aircraft structure. A separation device, such as a pneumatic bladder, is positioned between the panel and the land structure and adjacent to the magnet, and is rigidly secured to the aircraft structure. The separation device is actuated to apply pressure to the panel and break the magnetic attraction between one or both of the panel magnetic foundation member and the magnet or the land magnetic foundation member and the magnet.
