    摘要： A base station for an unmanned aerial vehicle (UAV) is disclosed that includes: an enclosure defining an internal cavity that is configured to receive the UAV; a door that is movably connected to the enclosure; actuators that extend between the door and the enclosure to facilitate opening and closure of the door; a cradle that is configured to receive the UAV and which is movable in relation to the enclosure such that the cradle is repositionable between a retracted position and an extended position to facilitate movement of the UAV into and out of the enclosure; and engagement members that are secured to the actuators and which are configured for contact with propeller assemblies on the UAV to facilitate folding of the propeller assemblies during movement of the UAV into the enclosure.

    摘要： An electrical communication system for unmanned aerial vehicle that includes conductive contact surfaces with magnets that are attached to a landing platform, and conductive pin systems that are attached to the vehicle. Each conductive pin system includes a conductive pin that its lower end is made of a magnetizing material, and its upper end is connected to the controller and the battery of the vehicle. The conductive pin systems includes a main body, that is attached to the vehicle, with a hole inside which the conductive pin is penetrated, a nut assembled on the upper end of the pin, a spring that is wounded on the pin between the nut and the main body so that the spring pushes upwards the pin, and a cable connector that is connected to the upper end of the pin to enable electrical connection with the controller and the battery.

    摘要： A rechargeable battery assembly has a first battery unit with a first terminal and a second terminal; a second battery unit which is serially connected to the first battery unit and which has a first terminal and a second terminal; and a differential amplifier with an inverting input, a non-inverting input, and an output at which an amplified difference between the signal at the inverting input and the signal at the non-inverting input is produced. The non-inverting input of the differential amplifier is connected to the second terminal of the first battery unit and to the first terminal of the second battery unit. The inverting input of the differential amplifier is coupled to the first terminal of the first battery unit and to the second terminal of the second battery unit. The output of the differential amplifier is connected to the second terminal of the second battery unit. A coupling element with two load connections is connected between the output of the differential amplifier and the second terminal of the second battery unit. The coupling element allows the second battery unit to be charged via the coupling element but at most allows a minimal discharge of the second battery unit in the direction of the output of the differential amplifier.
