  • Publication number: 20120113065
    Abstract: A stylus input device includes a grip, a surface-contacting member, a pivot joint, and first and second sensor modules. The pivot joint is disposed to connect the grip to the surface-contacting member and permit tilting of the grip relative to a working surface when the surface-contacting member is in intimate contact with the working surface, and is configured to permit and guide axial displacement of the grip relative to the surface-contacting member. The first and second sensor modules are disposed respectively in the surface-contacting member and the grip for sensing two-dimensional movement of the surface-contacting member on the working surface and axial displacement of the grip so as to respectively generate a two-dimensional movement signal and an axial displacement signal that are to be converted into a positioning signal by a processing unit for subsequent transceiving by a transmitting module.

  • Patent number: 4905934
    Abstract: The gust alleviation system was designed to be an add-on to any existing g-command flight control system. The system assumes that there already exists, a stability augmentation system which will hold the aircraft's attitude. This system minimizes the interaction of the gust alleviation system with the existing flight control system. The gust alleviation system picks off the stick displacement signal and the aircraft normal acceleration sensor signal and processes this information. The outputs of the gust alleviation system are added back respectively to the existing flap command signal and the aircraft's original stability augmentation loop.

  • Patent number: 4797829
    Abstract: A flight control system utilizing multi-controlled surfaces to provide the necessary control power and feedback logic to stabilize the aircraft with minimal noise amplification. In addition, a unique performance optimization loop is integrated into the stability logic to position the multi-control surfaces for optimum maneuver performance.

  • Patent number: 4767085
    Abstract: A synthetic speed stability subsystem for maintaining the speed and phugoid stability of an inherently unstable aircraft is connected to a main flight control system. The speed stability subsystem uses the pitch and roll angles, and the equivalent air speed of the aircraft for calculating a synthetic speed stability signal, which is fed to the main flight control system, for controlling the stability of the aircraft.
