Abstract: A headphone device having a listening configuration and a storage configuration. In the listening configuration, the headphone device is configured to provide an ergonomic fit for a user when the headphone device is worn on the user's head with earcups oriented over the user's ears. In the storage configuration, the headphone device is configured to provide an ergonomic fit for the user when the headphone device is worn around the user's neck.

Abstract: An electronic device for playing audio information to a user includes a body and an ear insert. The body has a speaker therein. The ear insert includes an integrated fin and sound director. The fin and sound director are oriented opposite one another at opposite ends of the ear insert in a longitudinal direction. The fin and sound director each project beyond the body in the longitudinal direction. The sound director is in audio communication with the speaker to direct sound from the speaker through and out of the sound director.

Abstract: A method for selecting members in a hierarchy includes determining a sequence of one or more actions associated with a member selection tree. The actions collectively selecting one or more members from a hierarchy of members. The hierarchy of members is associated with a particular dimension of an organization of data. The method further includes recording the sequence of actions in a member selection script. In addition, the method includes executing the member selection script to select one or more members after the hierarchy of members has been modified.

Abstract: A system for use on a surface to collect solar energy from the sun has a stand, a module, and solar collector(s). The stand supportable on the surface has rotational points rotatably supporting the module so it can rotate about a first axis of rotation. A first drive disposed on the stand is operable to provide first rotation, and a cable connected between a hoop pulley of the module and the first drive on the stand can rotate the module about the first axis to direct the solar collector(s) toward the sun. The solar collector(s) disposed on the module can be photovoltaic cells for collecting solar energy. A second drive on the module can rotate an adjacent solar collectors on the module using pulleys and cable. Reflectors on the collectors can focus the sun rays to photovoltaic cells. The second drive can rotate the collectors about a second axis, carried by the first axis, to direct the solar collector(s) toward the sun.

Abstract: Conversation user interfaces that are configured for virtual assistant interaction may include contextual interface items that are based on contextual information. The contextual information may relate to a current or previous conversation between a user and a virtual assistant and/or may relate to other types of information, such as a location of a user, an orientation of a device, missing information, and so on. The conversation user interfaces may additionally, or alternatively, control an input mode based on contextual information, such as an inferred input mode of a user or a location of a user. Further, the conversation user interfaces may tag conversation items by saving the conversation items to a tray and/or associating the conversation items with indicators.

Abstract: A modular aft galley and lavatory complex is disclosed. The galley complex is situated aft of an aircraft passenger cabin and incorporates left-side, right-side, and aft galley structures together partially enclosing an interior workspace, the left-side and right-side galley structures separated by a center aisle. Each galley structure includes trolley bays capable of securing trolleys therewithin. Each trolley can be removed from its trolley bay into the interior workspace or central aisle for use in catering or service operations inflight. Each galley structure includes storage bays accessible from the interior workspace. Between the upper and lower portions are flat workdecks and galley insert bays capable of accepting ovens, chillers, beverage makers, and other galley insert devices. Either the left or right galley structure includes a lavatory complex adjacent to the passenger cabin, incorporating aft lavatory units and a galley extension housing additional storage and cart space.

Abstract: An aircraft lavatory complex incorporating lavatories accessible to passengers of reduced mobility (PRM) is disclosed. Left-side and right-side full service lavatory units are accessible via left-side and right-side lavatory access doors opening in opposing directions. The left-side and right-side full service lavatory units are separated by a common central partition repositionable by cabin crewmembers (but protected from independent repositioning by occupants of either lavatory unit) to enlarge either of the left-side or right-side lavatory units for enhanced PRM accessibility.

Abstract: Medical wound irrigation systems are described that may be used in environments such as hospitals and first aid stations, and for military applications, e.g., for medics and along transport routes for the wounded. The irrigation systems can provide continuous variable pressure for irrigating a wound. For example, in some embodiments, a medical irrigation system can be used to provide a steady pressure level while irrigating about one liter of solution in less than about one minute, e.g., to assist during wound irrigation and debridement. The medical irrigation system may include an air-powered irrigation device, which pressurizes an irrigation solution, such as a cleansing fluid, to create an ejection force. In some embodiments, the medical irrigation system can include a replaceable bottle cap with an inlet for connecting to a source of pressurized fluid (e.g., pressurized gas, such as pressurized air) and an outlet for the irrigation solution/cleansing fluid.

Abstract: Disclosed herein, is a process for recovering valuable metals and/or their oxides from red mud bauxite residues or similar. The process comprises: calcining a red mud residue having a pH of less than about 10 to provide a calcinated red mud residue; acid leaching the calcinated red mud residue to provide a silica rich solid component and an acid leachate; separating the silica rich solid component and the acid leachate; precipitating an iron rich solid component from the acid leachate; and separating the precipitated iron rich solid component from the acid leachate to provide an aluminium rich liquor.
