Abstract: Methods and systems are provided for controlling attitude of a vehicle using a reaction wheel onboard the vehicle. One exemplary method involves receiving a torque command for adjusting the attitude of the vehicle using the reaction wheel, determining a phase error of the reaction wheel based at least in part on the torque command, and determining a motor torque command for the reaction wheel based on the phase error. The motor torque command is provided to an electric motor of the reaction wheel to apply a corresponding torque to the rotor of the reaction wheel. The relationship between the magnitude of the motor torque command and the magnitude of the phase error is nonlinear. In exemplary embodiments, the magnitude of the motor torque command exceeds the stiction torque, at least instantaneously, when the reaction wheel has fallen behind an expected position by more than a threshold amount.

Abstract: Methods and systems are provided for orienting an agile vehicle using a control moment gyroscope array. A method comprises obtaining initial vehicle parameters for the vehicle and obtaining target vehicle parameters for the vehicle. The method further comprises determining command parameters based on a difference between the target vehicle parameters and the initial vehicle parameters, and simulating operation of the control moment gyroscope array using the command parameters and a torque value being at least equal to a maximum achievable torque for the control moment gyroscope array. When the simulated vehicle parameters are substantially equal to the target vehicle parameters, the method further comprises determining a torque profile for the control moment gyroscope array based on the simulated operation and operating the control moment gyroscope array using the torque profile.

Abstract: The present method provides a method for avoiding singularities in the movement of CMGs in an array of CMGs in a spacecraft. In a first step, a torque command representing a desired torque to produce an attitude adjustment for the spacecraft is received. Next, a range-space gimbal rate required to produce the desired torque based on the desired torque and a Jacobian matrix is calculated. Then, a null-space gimbal rate that assists in the avoidance of singularities is calculated. The total gimbal rate command is determined by summing the range-space gimbal rate and the null-space gimbal rate. Then, the total gimbal rate command is provided to the CMGs to produce the total gimbal rate.

Abstract: Systems, methods, and computer program products for generating a narrative financial analysis of a financial statement of a business entity are provided. Financial information about a business entity is obtained from a user. A set of financial values is calculated based on the received financial information. The calculated values are compared to values calculated for the same business entity over time or to different business entities in the same industry. Scores are assigned to the financial values based on the comparison. For each combination of scores, text is dynamically selected to generate a narrative financial analysis report. The narrative financial analysis report includes text that explains the meaning of each combination of scores in a narrative format.

Abstract: A dual-function tire inlet valve mountable on a tire in communication with a compressor in a tire pressure maintenance system is disclosed. The inlet valve has a conduit extending from an ambient air supply to an interior chamber of the tire. A first check valve and a second check valve are positioned within the conduit to define a pump between the first and second check valves. The pump channel is in fluid communication with a compressor in the tire pressure maintenance system. The first check valve opens automatically only when the compressor is active and the tire is rotating about its axis with at least a pre-determined velocity. The second check valve only opens when it is manually actuated. Manually actuating the first check valve opens the second check valve to permit manual adjustment of the tire pressure.
