  • Publication number: 20250063984
    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.

  • Publication number: 20240307224
    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.

  • Patent number: 10560591
    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.

  • Patent number: 10193886
    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.

  • Patent number: 9894393
    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.

  • Patent number: 9680462
    Abstract: Various embodiments are described herein for methods and systems of regulating incoming voltage supplied from a utility power supply to a load. In one example embodiment, a voltage regulator adapted to be electrically interposed between the utility power supply and the load, each having at least one phase, is provided. The voltage regulator comprises an autotransformer having, for each phase, a series winding and a regulating winding, where the regulating winding has a plurality of taps and the series winding has a load side for connection to the load and a supply side for connection to the utility power supply.

  • Patent number: 9397351
    Abstract: Embodiments relate to a fuel cell including, an ion conducting component, two or more electrode coatings and one or more interconnects. The interconnects include a non-conductive interface region having a first surface and a second surface in which the first surface is in contact with the ion conducting component, an electron conducting component having two surfaces and a length that is parallel to the two surfaces wherein one of the surfaces is disposed adjacent to the second surface of the interface region. The electron conducting component provides an electrically conductive pathway between one of the electrode coatings and an external circuit, said pathway extending along the length of the electron conducting component.
