  • Publication number: 20200218287
    Abstract: Exemplary embodiments described in this disclosure are generally directed to a multi-drone automotive system that includes a first drone configured to carry one or more detachable drones. The first drone, which may be referred to as a carrier drone, may be mounted upon an automobile and operated in a tethered mode of flight. The detachable drones may be launched from the carrier drone to carry out untethered flight. The carrier drone and/or the detachable drones may be used for various applications. In one example application, the carrier drone may use a first camera that is mounted upon the carrier drone, to capture a first set of images during the tethered mode of flight. A detachable drone may be launched from the carrier drone in an untethered mode of flight in order to capture a second set of images by using a second camera mounted upon the detachable drone.

  • Patent number: 9685790
    Abstract: Approximately one-half of the loss of delivered power from a solar panel having photovoltaic (PV) cells connected in series to form sub-panels due to shading is recovered at low hardware cost by connecting sub-panels in series and providing maximum power point tracking control in common for the series connected sub-panels such that the respective sub-panels produce equal voltages even in the presence of shading of a portion of one or more sub-panels. By doing so, the input voltage of respective power converters which control the voltage at which each sub-panel is operated can be placed close to the maximum power point of each sub-panel regardless of shading and maximum total power harvested even though the respective sub-panels are not operated at optimum voltages.
