Abstract: An exemplary method of using a virtual assistant may include receiving an unstructured natural-language user request for a service from a virtual assistant; determining whether the user request corresponds to at least one of a plurality of plan templates accessible to the virtual assistant, based on the content of the user request and the content of the plan templates; in accordance with a determination that the user request corresponds to at least one of the plurality of plan templates, selecting one of the plurality of plan templates; and in accordance with a determination the user request fails to correspond to at least one of the plurality of plan templates, foregoing selection of a plan template; and in response to selection of one of the plan templates, beginning to respond to the user request according to the selected plan template.

Abstract: A non-transitory computer-readable storage medium stores one or more programs including instructions, which when executed by an electronic device of a user, cause the electronic device to generate at least one experiential data structure accessible to a virtual assistant; modify at least one experiential data structure with one or more annotations associated with the experiential data structure, utilizing the virtual assistant; store at least one experiential data structure; receive a natural-language user request for service from the virtual assistant, and output information responsive to the user request using at least one experiential data structure. The experiential data structure is a data structure that includes an organized set of data associated with at least one of the user and the electronic device at a particular point in time.

Abstract: A user controls an external electronic device with a finger-ring-mounted touchscreen that includes a computer processor, wireless transceiver, and rechargeable power source; the ring is worn on a first finger receives an input from a second finger, selects one of a plurality of touch events associated with the input, and wirelessly transmits a command associated with the touch event to the external electronic device.

Abstract: The present invention relates to a method and an associated apparatus (1) for the recovery and regeneration of metal powder in EBM (Electron Beam Melting) applications. The method is of the type which envisages a step for recovery of weakly sintered powders inside a cleaning chamber (2) incorporating at least one compressed-air nozzle with supply, where necessary, of powder for sandblasting three-dimensional objects obtained by means of EBM sintering of the metal powders; according to the invention it is envisaged supplying into the cleaning chamber (2) metal powders having a predetermined low oxygen content and there is also a powder recirculating system (3) comprising at least one first buffer tank (9) inside which the regenerated powders are deposited for renewed supply of the aforementioned chamber (2).
