  • Patent number: 9146068
    Abstract: A motorized weapon gyroscopic stabilizer which creates a stabilizing effect for single shot, semi-automatic, and fully automatic weapons. The rotating mass that generates the gyroscopic stabilizing effect is the rotor of the motor. The motor is designed to allow the mass to rotate around the open core of the motorized weapon gyroscopic stabilizer. Because of its open core design the motorized weapon gyroscopic stabilizer allows the fired projectile to pass through it, or be mounted in line with the sighting mechanism allowing the target alignment—line of sight to pass through the motorized weapon gyroscopic stabilizer, or both.

  • Patent number: 9140341
    Abstract: A gyroscopic device is described for providing rotation about at least one output axis and a method for providing rotation. A body (2) is mounted for a rotation about first (4), second (11), and third (16) axes. The first axis (4) is oriented with respect to the second axis (11) at an inclination angle. The second axis (11) and/or the third axis (16) constitute the at least one output axis of device. The rotation of the body (2) about the third axis (16) gives rise to a change in the inclination angle. A ram (15) applies a torque (21) to the body (2) about the third axis (16) in a sense of increasing inclination angle when the first axis (4) is at a selected inclination angle with respect to the second axis (11) which is greater than 0° and less than 90°. The rotation of the body (2) about the third axis (16) in a sense of decreasing inclination angle is limited such that the inclination angle of the first axis (4) with respect to the second axis (11) remains greater than 0 degrees and less than 90 degrees.

Hence the revolutionary speed of the rotor (8) varies depending upon changes in the output load and the same holds true for the rotational speed of the output shaft (5), which makes the speed ratio spontaneously vary with changes in the outpot load. Accordingly, the transmission of the present invention operates at speed ratios spontaneously varying with changes in load, without any controlling operation.

    Abstract: A torque amplifying device that is of centrifugal or gyroscopic type and has a unidirectional drive or drives. This device is used to control the body of a controlled object. The controlled object can be an airplane, helicopter, land vehicle, cargo handling mechanism, earth moving machine or maritime device or vehicle. The torque amplifying devices are designed so that they supply a torque (momentum) to the body of the controlled object where it is connected. Thereby, the orientation or weight distribution of the body is controlled. The orientation is achieved without resorting to the physical properties of the surrounding environment (ground, water or air). Thus, it can apply a torque to this body in pitch, roll and/or yaw, so that it achieves the position or weight distribution the control system is calling for. The duration of the torque can be unlimited, until the conditions that produce it are intentionally changed.

  • Patent number: 6789437
    Abstract: An apparatus and a method for controlling the path of oscillatory travel of a device within a two-axis system. A device, such as a camera, is held in a two axis gimbal system having motors for driving the azimuth and pitch axes. A two degree-of-freedom gyroscope is fixed to the case of the device. A first derivative circuit is interposed between a first input port for a loop for controlling device movement with respect to a first axis and a second input port for a loop for controlling device movement with respect to a second axis. Likewise, a second derivative circuit is interposed between the two input ports so that a periodic signal driving with respect to one axis generates a derivative function for driving with respect to the cross-axis. The cross axis signal is scaled to counteract the direct torquing of the gyro rotor that otherwise prevents smooth oscillatory slewing or scanning by the device.

  • Patent number: 6640659
    Abstract: A transmission is provided which includes a fixed housing or support, an input part moveable relative to the support and a torque shaft, a first one-way clutch between the torque shaft and the driven shaft, linkage elements rotatable about the axis of rotation of the driven shaft under the influence of the input parts and an inertial body mounted on the linkage elements to be cyclically angularly deflected in response to the input part, the reaction forces generated by the inertial body as it cyclically deflected being applied to the torque shaft as a positive and negative torque and the torque shaft being connected over a second one-way clutch opposite to the first one-way clutch either to the support or to the driven shaft over a rotation reversal system whereby the driven shaft can be rotated by the torque shaft in one sense of rotation only.

  • Patent number: 6530289
    Abstract: In the case of a navigation computer of a motor vehicle, the housing of a gyroscope is arranged in the housing wall of the navigation computer such that the angle of the gyroscope can be adjusted. For this purpose, the invention provides that the housing of the gyroscope has two mutually opposite spring tongues (5, 6) which are directed upward and simultaneously radially outward from the top side of the gyroscope, and the housing wall has a holder (2) with two opposite passages (7, 8) for pushing through the spring tongues (5, 6) and, adjacent in each case to the passages (7, 8), a rotary member (9, 10) each in the shape of a circular arc as bearing surface for the spring tongues (5, 6).

  • Patent number: 6527071
    Abstract: Appliance such as a two-legged robot made up of a system giving ground support and an upper body (30), equipped with a gyroscopic rotor wheel (31) which acts as a fulcrum to balance the appliance when positioned in reverse pendulum. A satisfactory equilibrium is guaranteed, thereby releasing from this function the command system in charge of robot locomotion or pathway.

  • Patent number: 6360838
    Abstract: A system for balancing two-wheeled vehicles when approaching rest or when at rest is provided. The system includes a spinning gyro rotor which is precessed upon the sensing of incipient tipping of the vehicle when the vehicle is at rest or approaching rest for generating a force for preventing such tipping. The system may be packaged in a small module that can be mounted on existing two-wheeled vehicles.

  • Patent number: 6301982
    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.

  • Patent number: 6276985
    Abstract: A gyroscopic motion device constructed for relative motion over an external support structure. The device includes a frame structure configured to support a pair of spaced apart gyroscopes. The device also includes a substructure operatively interposed the pair of gyroscopes which initiates a precessing effect, which results in a change in the angular disposition of the axes of rotation of the gyroscopes to cause the device to move relative to the external support structure.
