  • Perching attachment for unmanned aircraft
    Patent number: 10081421
    Abstract: An aerial vehicle system includes a flight system configured to generate propulsive force and lift, a protective framework, and an attachment mechanism secured to the protective framework and configured to selectively attach to a structure to provide stable perching of the aerial vehicle system. The attachment mechanism is an electro-permanent magnet device or a talon-like grip. The flight system is at least partially enclosed by the protective framework.
    Type: Grant

  • Method and apparatus for signal reception with ambient light compensation
    Patent number: 9154228
    Abstract: A free space communications apparatus includes a first receiving element configured to receive a communication signal and an ambient noise signal and to generate a first current as a function of any and all received signals, a second receiving element electrically coupled with the first receiving element to receive the ambient noise signal and to generate a second current as a function of any and all received signals, and an output signal produced as a function of the communication signal received by the first receiving element. The first and second receiving elements are electrically connected in a circuit that cancels at least a portion of the first current as a function of the second current to produce the output signal.
