Abstract: The present document describes a power converter configured to convert electrical power at an input voltage at an input of the power converter to electrical power at an output voltage at an output of the power converter. The power converter comprises a first upper capacitor and a first lower capacitor, which are coupled with one another via a first mid node; a second upper capacitor and a second lower capacitor, which are coupled with one another via a second mid node; an inductor; and a set of power switches. In addition, the power converter comprises a control unit which is configured to control the set of power switches such that during an operation cycle the power converter is operated in a first main state and in a second main state in a mutually exclusive manner.

Abstract: Aerial vehicles are assigned to routes within a transportation network based on a state of charge, state of power, and/or state of health for the aerial vehicle. Such aspects can be modeled based on one or more statistical models and/or machine-learned models, among other examples. As another example, an energy budget is used to ensure that the state of charge, state of power, and/or state of health of the aerial vehicle during and/or after traveling the route remains within the energy budget. A payload is assigned to a route and an associated aerial vehicle, thereby generating an itinerary. In examples, the itinerary is validated by the aerial vehicle to ensure that the aerial vehicle is capable of traveling the route with the payload. In examples where the aerial vehicle rejects the itinerary, the itinerary is assigned to another aerial vehicle and a new itinerary is identified for the aerial vehicle.

Abstract: A mower includes a cutting deck supporting a cutting blade having a fixed blade sail and a door having a first position in which the door covers an opening through which grass clippings can pass, and a second position in which the door does not cover the opening. The mower also has a switch configured to send a mode signal indicating that the door is in the first position or the second position. The mower also has a controller configured to receive the mode signal and adjust the cutting blade to rotate at a first speed when the mode signal indicates that the door is in the first position, and a second speed when the mode signal indicates that the door is in the second position. The mower also includes an electric battery to power rotation of the cutting blade.

Abstract: Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

Abstract: A method of remotely activating a transaction device includes receiving, at a computing system, a mobile device identifier from a mobile application executed on a mobile device. A selection of the transaction device is received from the application. The selection includes an identifier of the transaction device. A selection of a transaction amount related to purchase of a product is received from the application. An authorization request for a payment account associated with the mobile device is communicated to an issuer of the payment account. The authorization request is for a transaction of at least the transaction amount. An authorization approval for the transaction is received from the issuer and a signal to activate the transaction device to dispense the product is sent based on the identifier. The transaction device is deactivated upon dispensing the transaction amount and a receipt of the transaction is provided to the mobile device.

Abstract: Systems and methods to automatically transfer audiovisual content include camera devices, client computing devices, and centralized servers. A camera device captures audiovisual content and notifies an external entity, e.g., a (client) computing device or a centralized server. The external entity may effectuate transfer of the content to other computing devices and/or destinations. Operations on the audiovisual content, including but not limited to tagging, transcoding, clipping, speed changes, and/or image cropping, are synchronized and propagated across different computing devices and the centralized server such that any user from any computing device can be presented with the latest version of any particular audiovisual content.

Abstract: Conventional wireless interface (WiFi) controllers cannot resolve authentication for trusted client devices without calculation from a host processor. Leaving the host processor on or awaking it from a sleep state each time a non-authenticated trusted client device attempts to connect wastes power. A hostless authenticated wake service allows a host controller to enter a sleep state while the WiFi controller responds to multicast domain name service-service discovery (mDNS-SD) queries from trusted client devices. Once a client device is authenticated, the WiFi controller may respond to a trusted client request to awake the host processor for further command processing and service provision. Not only does this approach reduce power consumption by allowing the host processor to remain in the sleep state, it allows trusted client devices to discover its presence while ensuring security.

Abstract: A client device requests a streaming video from a storage device, which encodes the video's frame in communication packets according to an encoding protocol for transmission to the client. The client device decodes the communication packets to obtain frame segments and a frame marking header indicating a boundary of the video frame relative to other video frames in the video. The communication packets may also include other segment headers indicating a relative ordering of corresponding frame segments. The client device determines, based on the frame marking header, whether a sufficient number of communication packets have been received to render a video frame. In response to determining that the sufficient number of communication packets has been received, the client device assembles the video frame from the frame segments corresponding to the video frame and presents at least a portion of the video by rendering the assembled video frame.
