  • Patent number: 9855512
    Abstract: Horizontal control of a toy flying vehicle intended for indoor hovering flight comprises providing the vehicle having a rotor and a separate remote controller for use by a player of the toy. The vehicle is airborne relative to the controller. A signal is sent from a transmitter with the toy to the controller. A variation in intensity of the received signal from the toy being effected in a horizontal plane of the controller. The controller is programmed to transmit a responsive signal to the toy according to the variation of intensity of signal received and thereby to cause the toy with the transmitter in the toy to move horizontally and to thereby retain the received signal in the horizontal direction of the controller at a first predetermined level.

  • Patent number: 9746936
    Abstract: A controller includes a substrate is fixed relative to a movable plate. When a movement or an input operation on the movable plate or surface is detected, a drive signal is directed to drive electrodes or elements related to the substrate. The drive signal is modulated with signals dependent on the location of the movable plate. The movable plate is part of a including a plate being flat plate-like in shape. A movable plate support section supports the movable plate on a support structure so as to permit the movable plate to be moved along a plane lateral and parallel to the plate surface of the movable plate. An actuator is configured to respond to the movable plate; an actuator drive control section for outputting an actuator drive signal to drivingly control a sensor as signaled by the actuator drive control section.

  • Patent number: 8639400
    Abstract: Altitude control of a toy flying vehicle intended for indoor hovering flight comprises providing a selected altitude level for the vehicle. A position control signal is transmitted from the vehicle towards a surface. A receiver in the vehicle receives the signal reflected from the surface. A level of the reflected signal by the receiver is determined, and a change of the reflected signal is an indicator of a change of altitude of the vehicle relative to the selected altitude level. The vehicle receiver communicates with the remote controller, and the remote controller can adjust and control speed and direction of the vehicle. Controlling the altitude can be by a stop control; an up and/or down control; and/or a high and/or low height sensitivity control, take-off/landing control; gesture mode control; left/right trim control; control between altitude control mode and manual control mode.
