Abstract:
A service unmanned aerial vehicle (UAV) includes a flight system, a status component, a navigation system, and a recovery component. The flight system is for flying the service UAV. The status component is configured to determine that a first UAV is disabled. The navigation system is configured to fly the service UAV to a landing location of the first UAV in response to the status component determining that the first UAV is disabled. The recovery component is configured to recover one or more of a payload of the first UAV and a portion of the first UAV.
Abstract:
A graphene sheet is provided. The graphene sheet includes a carbon lattice and a spatial distribution of defects in the carbon lattice. The spatial distribution of defects is configured to tailor the buckling properties of the graphene sheet.
Abstract:
An electronic game feedback system includes a display device, a sensor system, and a feedback device. The display device is configured to provide a display of a virtual environment associated with an electronic game to a user. The display device at least partially obstructs the view of the user of a physical environment surrounding the user. The sensor system is configured to acquire object data regarding an object located within the physical environment. The feedback device is configured to provide feedback to the user based on the object data and indicative of a location of the object relative to the user.
Abstract:
A metal-air battery is disclosed, including a cathode temperature controller that identifies a power-boosted operating temperature at which a projected power boost exceeds a projected battery lifetime penalty and a temperature regulator that adjusts the cathode temperature to the power-boosted operating temperature using power generated by the metal-air battery when the metal-air battery is in a discharge state.
Abstract:
Embodiments include wearable haptic feedback devices and methods of fabricating wearable haptic feedback devices. In an illustrative embodiment given by way of non-limiting example, a wearable haptic feedback device includes: a wearable headgear cap; a web disposed within the cap; a plurality of haptic elements disposed about the web and configured to provide haptic feedback to a user; and an interface circuit configured to operatively couple the plurality of haptic elements to an electronic system.
Abstract:
A system for sealing a leak within a pipeline for transporting fluid includes a sealing device that is deployable to seal the leak. The sealing device includes a flexible wall formed into a substantially tubular shape defining an opening, and an internal frame coupled to the flexible wall and configured to control a movement of the flexible wall by applying a force to the flexible wall, wherein the movement of the flexible wall moves the sealing device through the pipeline. The system also includes a sensor assembly configured to monitor a pipeline condition and send a signal representing the pipeline condition, and a control module configured to receive the signal and control the force applied by the internal frame based on the signal.
Abstract:
Inter-substrate coupling and alignment using liquid droplets can include electrical and plasmon modalities. For example, a set of droplets can be placed on a bottom substrate. A top substrate can be placed upon the droplets, which uses the droplets to align the substrates. Using the droplets in a capacitive or plasmon coupling modality, information or power can be transferred between the substrates using the droplets.
Abstract:
An agricultural access system is described. The system may utilize a plurality of supports, including posts, cables, beams, and so forth to displace an access component. Control systems, sensors, delivery mechanisms, and other functions may be integrated with the system or access components. Some embodiments may include multiple cells with access components configured to interact with adjacent access components. Methods of accessing an agricultural area are also disclosed.
Abstract:
An adjunct for a gastrointestinal device and a system including said adjunct are described herein and include a substrate configured to attach to a gastrointestinal device, the substrate including a first surface and a second surface, and at least one microbe-promoting agent associated with at least one of the first surface and the second surface of the substrate, the at least one microbe-promoting agent configured to promote at least one of attraction, colonization, and growth of at least one type of commensal microbe.
Abstract:
A method for sealing a leak in a pipeline used to transport fluid includes positioning a sealing device within the pipeline, moving the sealing device through the pipeline to a leak location, and internally generating an inflation pressure to inflate the sealing device to substantially cover a leak opening and limit release of the fluid from the pipeline.
