And Eccentric Weight Patents (Class 446/458)
  • Patent number: 11040747
    Abstract: Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

  • Patent number: 10118104
    Abstract: A rolling toy to be rolled on a horizontal support surface, for instance, on a floor, having a primary roller and a secondary roller. The primary roller having a tubular-like member extending along a longitudinal axis and at least one annular flange fixedly attached to the tubular-like member and extending outwardly therefrom. The secondary roller is adapted a for rolling motion upon an interior surface of the tubular-like member when the primary roller rotates about the longitudinal axis due to the rolling motion of the rolling toy on the horizontal support surface. At least one of the following includes a helical guiding means: (i) the tubular-like member and (ii) the secondary roller. Thereby, when the secondary roller is disposed on the interior surface of the tubular-like member and the primary roller is set in a rolling motion on the horizontal support surface in a predetermined direction, the rolling motion of the primary roller results in a tilting of the latter.

  • Patent number: 8591281
    Abstract: An apparatus includes a housing, a rotational motor situated within the housing, a vibrating mechanism, and a plurality of appendages each having an appendage base proximal to the housing and an appendage tip distal from the housing. One or more of the appendages are adapted to cause the apparatus to move across a surface in a forward direction generally defined by a longitudinal offset between the appendage base and the appendage tip, and the appendages include two or more appendages disposed such that the appendage tips of the two or more appendages are adapted to contact opposing surfaces to produce a net force in a direction generally defined by a longitudinal offset between the appendage base and the appendage tip of the two or more appendages as the vibrating mechanism causes the apparatus to vibrate. The net force can allow the apparatus to climb when the opposing surfaces are inclined.

  • Patent number: 8322471
    Abstract: An apparatus and method are described for utilizing internally generated angular momentum for supplementing the propulsion of a mobile spherical vehicle capable of motion by rolling over terrain, thereby enabling such vehicles to climb steeper inclines and overcome larger obstacles. Torque generated by counter-rotating gyroscopes was used to supplement gravity generated torque produced by a pendulum drive propulsion system. Precession torque may be generated along a desired axis by changing the angular momentum of the gyroscopes while leaving its magnitude unaffected.

  • Patent number: 8106749
    Abstract: A method and a system are provided for controlling a controller without physically touching the controller. A hand or other object interacts with a field surrounding the controller, altering the field. A change in characteristic of the altered field causes a corresponding movement of the controller that, in turn, corresponds to an amount of change in a parameter of a target device being controlled by the controller. The parameter of the target device is controlled by the controller while a user has no physical contact with the controller.

The disk wheel is defined to include a housing having first and second housing members, each housing member is substantially shaped as a half disk such that assembly of the first and second housing members forms a disk with a rounded outer surface to permit the housing to roll on a surface and a pair of outer sections. A transparent side portion is positioned along each outer surface of the pair of outer sections. Each transparent side portion includes a protuberance positioned about the center of the transparent side portion with a notch positioned thereon. The notch is used to accommodate an axle having ends which transverse the housing to rotatably position in the notches of both side portions.

  • Patent number: 7927170
    Abstract: A portable device comprises a motor for providing vibration, a power source for powering the motor, a switching device for controlling the direction of the motor, propelling means for engaging a surface and for propelling the device when the motor is vibrating, the propelling means extending downwardly at an angle to the vertical, and an input device connected to the switching device, the switching device arranged to switch the direction of the motor when the input device receives a predetermined signal. Advantageously, the propelling means comprise a set of bristles. By using angled bristles, this increases friction in the backwards direction and so causes the device to move forwards when vibrating. The bristles dig into surface when vibration tries to move the object backwards, and the bristles slide over surface when vibration tries to move object forwards.

  • Patent number: 7263137
    Abstract: A multivalued FSK modulation system is provided in which when data to be transmitted is multivalued and transmitted/received, the detection level is different every symbol. When a two-valued signal is transmitted as one symbol, data (11), (01), (00) and (10) are previously set to be, for example, a shift of ?6, a shift of +6, a shift of +2, and a shift of ?2, respectively. When data to be input next is (00), mapping is performed so as to provide a sign weight of +2 from the sign weight at the position of current data. When the data to be input next is (10), mapping is performed so as to provide a sign weight of ?2 from the position of the current sign weight. Thus, even if data of the same level is input, signals can be always detected in different levels, so that the sign detection point is not specified erroneously.

  • Patent number: 6227933
    Abstract: The robot ball comprises an encapsulating shell, a drive system and a steering system. The shell has an axis of rotation and an outer annular tread surface centered on the axis of rotation. The drive system is encapsulated in the shell and comprises a first motorized mechanism and a counterweight. The first motorized mechanism has a stator portion and a rotor portion centered on the axis of rotation and connected to the shell. The counterweight is connected to the stator portion and is spaced apart from the axis of rotation whereby, due to inertia of the counterweight, rotation of this rotor portion rotates the shell to roll the tread surface on the ground. The steering system comprises a second motorized mechanism through which the counterweight is connected to the stator portion. This second motorized mechanism includes a pivot assembly having a pivot axis transversal to the axis of rotation.

  • Patent number: 6149494
    Abstract: A toy includes a platform, a moving body, and a balance bar. The moving body has front and rear wheels rotatable about horizontal rotary axes, a turning wheel, and a drive unit coupled to the turning wheel and one of the rear wheels to drive movement of the moving body when the moving body is disposed on the platform. The turning wheel is rotatable about an axis perpendicular to the rotary axes of the front and rear wheels, and prevents the moving body from falling off the platform when the moving body moves to a peripheral edge of the platform. The balance bar has an intermediate fulcrum portion mounted pivotally on the moving body about a horizontal pivot axis, and two arm portions projecting from two opposite lateral sides of the moving body.

    Abstract: A self-propelled musical toy rolling ball which plays musical tunes and sound effects. The ball may also include decorative images on its surface which may generally correspond to the musical tune or sound effects played by the ball. The electronics of the ball, once energized, operate to propel the ball and simultaneously activate an integrated circuit sound effects chip which plays first sound sequence, typically a musical tune. When the ball bumps into a wall or other object, the propulsion mechanism, typically a drive motor which may be transmissivly connected to a central axis shaft, is disengaged and the circuit then plays a second sound sequence, typically a randomly selected pre-programmed sound effect from one of a plurality of different sounds. Thereafter, the propelling mechanism is again activated and the ball resumes playing the musical tune.
