Abstract: A spherical orienting device includes a base, first and second actuation shafts, an orientable device, an inner member, a middle member, and an outer member. The first and second actuation shafts are rotatably held by the base for rotary actuation about first and second actuation axes, respectively, which intersect orthogonally at a spherical center of rotation. The orientable device is supported by first and second revolute support joints which are disposed for rotation about an orientation axis of the orientable device and a support axis, respectively. The inner member is fixed to the first actuation shaft and linked to the second support joint. The middle member is inwardly linked to the first support joint and outwardly linked to a middle revolute joint disposed for rotation about a linkage axis. The outer member is fixed to the second actuation shaft and linked to the middle revolute joint.
Abstract: A rotor assembly is provided for deployment within the inner gimbal assembly of a control moment gyroscope (CMG). In one embodiment, the rotor assembly includes a rotor shell, a rotor shaft fixedly coupled to the rotor shell, and a rotor rim. The rotor rim includes an annular body and a strain relief member. A first end portion of the strain relief member is fixedly coupled to the annular body, and a second end portion of the strain relief member is fixedly coupled to the rotor shell to form a rim-shell joinder interface. The strain relief member has a flexibility sufficient to reduce the mechanical stress experienced by the rim-shell joinder interface during operation of the CMG.

Abstract: Gyrostabilizer methods and apparatus having simultaneously counter-revolving masses that do not require physical shafts or axles. The stabilizer can have dual counter-revolving concentric rings, or tracks filled with weights such as spherical balls, that are propelled in orbital fashion by fluid pressure or electromagnet propulsion. The rings can include rigid contiguous rings, such as metal, plastic, composites, and the like. Additionally, the rings can include liquids and/or gasses. Still furthermore, the rings can include flexible, bendable contiguous materials, such as chains and ropes. The concentric ring diameters can be a few inches to more than ten (10) feet. Without an axle or shaft the weight of the gyrostabilizer is shifted to the perimeter where most of the momentum is generated at a fraction of the weight of gyrostabilizers that spin on an axle. The gyrostabilizer can dampen unsteadiness such as tremors, vibrations, sway, pitch, roll, and yaw.
Abstract: A gyro torque converter includes an input shaft and an output shaft. The input shaft is fixedly connected to rotate a first drive member. A gimbal is supported by the input shaft. A second drive member is driven by the first drive member. A first shaft is driven by the second drive member. A drive unit is mounted on the first shaft. A second shaft extends from the drive unit. A plurality of gyro members are rotatably mounted on the second shaft.
Abstract: A gyro torque converter includes an input shaft and an output shaft. An outer gimbal is supported by the input shaft and the output shaft. An inner gimbal is rotatably mounted within the outer gimbal. The inner gimbal is connected to be rotatably driven by the input shaft. A gyro is rotatably mounted within the inner gimbal.
Abstract: A housed gyro-sensor 31 is housed in a rotation plate 33. The gyro-sensor 31 is mounted so that a rotation operation is enabled in a pitch axis direction about an axis in a mounting hole 24 formed on a housing of an inner face of the car navigation system 21. In this way, as shown in FIG. 8, even when the main body of the car navigation system 21 is not housed horizontally with respect to the vehicle, it is possible to regulate the mounting angle of the housed gyro sensor 31 in a horizontal direction by rotating the rotation plate 33. In order to realize how many times the rotation plate 33 needs to be rotated, standards for angle settings may be provided by directly printing the name of the vehicle type on an outer face of the rotation plate 33 or by printing the major angles.
