  • Patent number: 8430709
    Abstract: A flying toy has a propeller rotated by the first motor mounted on the body. A propeller holder mounts the propeller. An end cap is located to the front of the propeller holder, and there is a snap joint between the holder and the end cap. The end cap is removable by disengagement of holder and end cap at the snap joint, and the propeller is releasable from the holder by a human hand and without a tool. When the toy crashes, the propeller is forced relatively free from the drive force rotating the holder and back towards the body and is trapped against separation from the toy.

  • Patent number: 8371897
    Abstract: An interactive toy comprises a body having a non-reactive portion and a reactive portion. There is a CMOS image sensor with the body for capturing an image in the vicinity of the body. A microprocessor processes the captured image and generates instructions in response to the processed image. The instructions cause operation of the reactive portion of the body. The toy can be a doll including a plush, soft or hard plastic head and body; and the CMOS image sensor has a resolution of about or selectively less than 1M pixels.

  • Patent number: 8337274
    Abstract: A toy car and a remote control regulate the speed of the car. A source of supplemental power selectively energizes the drive motor thereby to selectively permit the vehicle to move faster than the normal speed. A sensor measures the voltage to the vehicle motor. After stepping up the voltage to the drive motor, and detecting a drive motor current increase in excess of the capability of vehicle, the source of supplemental power is disabled. When a normal low voltage state is detected, the source of supplemental power in the vehicle is enabled whereby the motor supply voltage is permitted to increase above a normal low voltage state permitting more power to be provided to motor.

  • Patent number: 8330639
    Abstract: A remote controller for toys includes a user interface which applies the low-cost capacitive sensing method with the remote controller. Users can touch and/or drag on a remote controller surface by fingers to remotely control the movement of R/C cars, planes, helicopters or a boat. The remote controller is essentially a flat faced unit and there is no need for protruding control sticks or pushbuttons. This controller is applicable to different types of remote control toys with digital proportional control on speed and steering control. The remote controller is a symmetric product design whereby the controller is easily operable with left and right hand conventions.

  • Patent number: 8308522
    Abstract: A flying toy comprises a first wing and a second wing attached to and extending from opposite sides of a fuselage. There is a first propulsion unit, having a first motor and a first propeller system rotated by the first motor, mounted with the first wing; and a second propulsion unit, having a second motor and a second propeller system rotated by the second motor, mounted with the second wing. Each propulsion system has main blades and auxiliary blades which interact with each other. Each of two wings can be angled relative to horizontal independently. The toy can operate as a plane or helicopter.

  • Publication number: 20120028538
    Abstract: A handheld electrical charger for a toy vehicle provides a manual handle on the housing for generating kinetic energy. A dynamo within the housing and in mechanical communication with the handle generates electrical energy from the kinetic energy. A power takeoff transfers a portion of the kinetic energy or the electrical energy to a power inlet for a toy, and the toy is separable from the charger. The toy includes an electrical storage device to be charged by electrical output from the inlet. The toy is operable as a toy under its own recharged electrical power when the power take off and power inlet is disconnected. There can be a power storage for DC power in the housing and/or in the toy. A dock is provided for selectively creating an electrical coupling of the toy vehicle to transfer the electrical power and decoupling to allow the vehicle to operate independently of the charger.

  • Patent number: 8075364
    Abstract: A storage housing is provided for stowing a remote control toy. The housing comprises a substantially box shaped body with an interior compartment. The compartment has a platform for movement between two positions, and a door for moving between an open and closed position. There is a remote controller for operating the platform and door in a selected manner and also for operating the remote controlled toy. The housing can additionally be part of a vehicle and have wheels.

  • Patent number: 8038504
    Abstract: A toy includes a vehicle body having a front portion and a rear portion. A pair of rear wheels is coupled with the rear portion and located on the vehicle so as to at least partially support the rear portion. A first electric motor is drivingly coupled with the at least one rear wheel. There is a pair of front wheels coupled with the front portion and located on the vehicle so as to at least partially support the front portion. An electrically operated steering actuator is mounted on the front portion and is drivingly coupled to the at least one front wheel to rotate the front wheels to steer the toy vehicle. When the vehicle is inverted, the sensor detects the orientation change and signals a microprocessor inside the vehicle, the microprocessor responds to the signal and changes the left/right motor control signal to the steering motor and the forward/backward motor control signal on the driving motor.

  • Patent number: 7883392
    Abstract: A toy helicopter, in accordance with the present disclosure, includes a body having a longitudinal length and a main rotor. There is an element movable along the longitudinal length. The element allows a user to selectively adjust the location of the center of gravity of a toy helicopter by moving the element along the longitudinal length, thereby changing the velocity of the helicopter.

  • Publication number: 20090163110
    Abstract: A remote-controlled toy helicopter comprises a body; a motor in the helicopter, a battery for powering the motor, and a receiver for communicating signals between the motor and a separate remote controller. A main rotor with blades is driven by a rotor shaft and causing a first lift force developed by the main rotor when the helicopter is airborne. A system permits movement of the helicopter on the ground, and these can be wheels. The helicopter travels on a floor or ground surface when the main rotor develops a second degree of lift force. The helicopter includes a system to effect motion in a horizontal dimension thereby to direct the desired direction. The control includes an actuator for engaging with an assembly depending from the rotor, the inter-engagement of the actuator and assembly effecting a change in the angle of incidence of at least the one blade of the rotor. The system includes a rotor, preferably complemented with a stabilizer rotor.
