  • Patent number: 11618474
    Abstract: A safety system for an autonomous electronic vehicle having a body and a platform. The safety system includes at least one mechanical connection unit and a safety control module. The mechanical connection unit connects the body to the platform, and is transitionable between a first state, in which the body is attached to the platform at the mechanical connection unit, and a second state, in which the body is released from the platform at the mechanical connection unit. The safety control module is programmed to prompt the mechanical connection unit to transition from the first state to the second state under circumstances of an imminent collision event. In some embodiments, the safety control module is programmed to determine a safety path for passengers within the body and/or others in the collision zone based on conditions surrounding the vehicle.

  • Publication number: 20200267462
    Abstract: A mobile communication device configured to be worn on an index finger of a user's hand. The device includes a case, a microphone, a switch, and a power source. The microphone and the switch are strategically located along a shape of the case so that as worn on the user's index finger and when the switch is activated by the thumb of the user's hand, the hand naturally cups about the microphone to form a barrier to ambient noise. Further, the microphone can readily be located near a corner of the user's mouth for optimal speech-receiving conditions and to provide more private audio input.

  • Publication number: 20190273464
    Abstract: Systems for collecting and storing solar energy including a solar energy capture and store device having a plurality of segments arranged in a contiguous row. Immediately adjacent ones of the segments are interconnected by a hinge such that the plurality of segments are transitionable between a collapsed, folded state and an expanded state. A photovoltaic layer is carried by at least one of the segments, and a power storage layer is carried by at least one of the segments. The power storage layer is electrically connected to at least one of the photovoltaic layers. An electronic connection is established between each immediately adjacent pair of segments. An electrical connections terminus delivers stored energy. A do-it-yourselfer (DIY) individual is afforded the ability to install and operate a solar energy collection device with little or no skills in the arena of power provision.

  • Patent number: 9555610
    Abstract: An LED light bulb device that includes a bulb body, a plurality of flexible circuit strips, and at least one LED. The flexible circuit strips are formed to a shape of, and adhered directly to, an interior face of the bulb body. At least one of the flexible circuit strips defines a plurality of stress-relieving notches. At least one LED is mounted to a corresponding one of the flexible circuit strips and is electrically connected to a conductive trace formed by the flexible circuit strip. The LEDs are arranged to aim inwardly relative to the bulb body. In some embodiments, a rear surface of each of the flexible circuit strips is adhesively attached to the interior face of the bulb body. In some embodiments, a plurality of LEDs are provided and arranged to provide one or both of uniform light distribution and diverse heat distribution.
