  • Patent number: 10082420
    Abstract: A method for determining the mass of a body is described. The method comprises the application and measurement of a first motive force to the body to move the body in a first state of motion. The acceleration of the body is also measured at this time. This methodology is repeated for a second state of motion. The measured motive forces and accelerations are then used to calculate the mass, and hence the weight of the body. An accelerometer may be employed to measure the accelerations. The methods may be adapted so as to correct for the angle ? of the ground across which the body is moved and or the tilt angle ? of the accelerometer relative to the ground. The methods may employ a novel surface angle measuring device that does not require contact with the ground and which does not require the body to be stationary.

  • Publication number: 20150100227
    Abstract: A method which creates a justification basis to expand an aircraft's Center of Gravity limitations, which are established by the aircraft designer; relating to aircraft landing gear strength assumptions. Strut load sensors such as pressure sensors are mounted in relation to each of the landing gear struts to monitor, measure and record aircraft landing gear strut compression loads. A history of measured landing gear load values is compiled and related to any assumed landing gear loads, which define the life-cycle limit of the landing gear, allowing relief from existing aircraft Center of Gravity limitation caused by landing gear strength assumptions to further expanded CG limitations beyond current limits, based on measured landing gear loads.

  • Patent number: 8977485
    Abstract: Embodiments of the present invention are directed to methods of autonomously self-righting a maneuverable robot. In one embodiment, an autonomous method for self-righting a maneuverable robot to affect recovery from an overturned state to its nominal upright configuration may include: defining a convex hull and center of mass of each link of the robot; determining the convex hull and overall robot center of mass for each joint configuration of the robot; analyzing each convex hull face to determine its stability or instability; grouping continuously stable orientations of the robot and joint configurations together defining nodes and transitions there between; assigning a cost to transitions between nodes; computing an overall cost for each potential set of transition costs resulting in achievement of the goal; and determining a sequence of one or more actions to self-right the robot such that the sequence of actions minimizes the overall cost of self-righting the robot.

  • Patent number: 8965674
    Abstract: A system includes a fluid reservoir containing a first fluid, a pair of fluidic channels in fluidic connection with the fluid reservoir, a counter-fluid reservoir having a second fluid that is non-miscible with the first fluid, and a pump connected to the fluid reservoir. The pump is configured to pump the first fluid from the fluid reservoir into the pair of fluidic channels. When contained in a vehicle, the system allows for control of the vehicle's orientation. The system may use sensor input to determine when to actuate the pump. Each fluidic channel may have a cross-section that varies along its length. The fluidic channels may be geometrically symmetric about the fluid reservoir. The system may be incorporated into a vehicle to control the vehicle's orientation.
