Abstract: A method for using a multi-stage in-air hand gesture to adjust volume at a pair of smart glasses and control a user interface of an application. The method includes causing display, at a pair of smart glasses, of a user interface for an application. The method further includes receiving data from a multi-stage in-air hand gesture from sensors of a wrist-wearable device and determining that the user is performing a pinch gesture for a threshold amount of time and a wrist-rotation gesture in a first rotational direction while the pinch gesture is maintained, and based on this determination, increasing a volume for speaker output at the pair of smart glasses. The method further includes determining the user is performing another pinch gesture for less than the threshold amount of time, and in response causing performance of an operation at the user interface for the application while maintaining the increased volume.

In one example, an apparatus is provided which comprises a connector component and a liquid deposition component. The connector component is configured to attach to an additive textile manufacturing machine that produces a textile product. The liquid deposition component is configured to deposit a liquid on one or more materials of the textile product.

Abstract: Systems and methods are directed toward low temperature testing of motion, vibration, or force responses of test fixtures. For cryogenic shock testing, a test object can be secured on a test apparatus, such as a test fixture of a shock table. An elongated enclosure, such as a flexible tube, can be connected between the test fixture and a laser vibrometer, positioned orthogonal to a surface normal at a test region of the test fixture to enable light emitted by the vibrometer to be reflected from the test region back to the vibrometer. A flow of purge gas can be introduced into the tube, proximate the test fixture, to direct moisture away from the test fixture. The flow can prevent condensation or ice from forming on the surface of the test fixture at the cryogenic temperature. A shock event can be simulated, and the response of the test region measured by the laser vibrometer. The impact of the shock event on the test object can then be observed.

Abstract: A method of determining an AR UI to present of a plurality of AR UIs is described. The method includes, in response to an indication to present user-interactable content via an augmented-reality (AR) headset, selecting an AR user interface (UI) of a plurality of AR UIs for presenting user-interactable content. The method includes, in accordance with a determination, based on sensor data obtained by the AR headset, that the AR headset satisfies a movement dwell threshold time, presenting the user-interactable content in a user-position based AR UI of the plurality of AR UI. And the method includes, in accordance with another determination, distinct from the determination, based on other sensor data obtained by the AR headset, that the AR headset satisfies a movement threshold, presenting the user-interactable content in a user-motion based AR UI of a plurality of AR UIs.

Abstract: The various implementations described herein include methods and systems for using hand gestures detected at a wearable device to navigate a user interface. An example method includes receiving, via one or more neuromuscular-signal sensors of a wrist-wearable device worn by a user, data generated during performance of an in-air wrist movement by a wrist of the user. The method also includes moving a point of focus on the user interface in accordance with the in-air wrist movement; and receiving, via the one or more neuromuscular-signal sensors, additional data generated during performance of an in-air gesture by the user. The method further includes determining that the in-air gesture is an execution gesture; and executing a command corresponding to the execution gesture.

Abstract: In one example, a porous tube assembly is described. The porous tube assembly comprises a material and at least one tube. The material is configured for an additive textile manufacturing process, and the at least one tube is integrated with the material by the additive textile manufacturing process. The at least one tube defines a hollow channel and one or more perforations that extend between the hollow channel and an outer surface of the at least one tube.

Abstract: A footwear article includes (a) an upper having a tongue opening at a front thereof; (b) a gusseted tongue including a tongue panel positioned over the tongue opening and a pair of gussets attaching laterally opposite sides of the tongue panel to the upper; (c) a pair of tongue fasteners configured to selectively fasten and unfasten corresponding sides of the tongue panel to and from the upper; (d) a first lacing system on the upper and arranged for guiding lacing over the gusseted tongue and tongue fasteners when the sides of the tongue are fastened to the upper; and (e) a second lacing system on the tongue panel and arranged for guiding the lacing across the tongue panel clear of the tongue fasteners when the sides of the tongue panel are unfastened from the upper.

Abstract: The various implementations described herein include methods and systems for using a multi-stage in-air hand gesture to activate user-interface interactions in a way that ensures low-false positive rates. In one aspect, a method includes, while a gating gesture is maintained, receiving a first indication of performance of an adjustment gesture of a first magnitude directed to a user interface object associated with a plurality of values. The method further includes, in response to receiving the first indication, adjusting the user interface object to have a first state after moving through some of the plurality of values based on the first magnitude. The method also includes, after receiving an indication of a release of the gating gesture, in response to receiving a second indication of performance of the adjustment gesture, forgoing adjusting the user interface object such that the user interface object continues to have the first state.
